1. INTRODUCTION

1.1 DescriptionDBREACH is a software program used to determine whether an earth embankmentovertopped during a flood will fail and, if so, the time and rate of failure. This information isused by TVA's Simulated Open Channel Hydraulics (SOCH) computer code for flood routingcalculations involving different dam failure scenarios in combination with different floodevents. DBREACH, along with seven other computer codes, is used to develop the requiredinput data for SOCH. These computer programs are used to meet United States NuclearRegulatory Commission criteria set forth in Nuclear Regulatory Guide 1.59 (replaced byAmerican National Standards Institute [ANSI] ANSI/ANS-2.8-1992). DBREACH softwarecodes and documentation must comply with TVA SPP-2.6, R12, Computer Software Control,(Reference 1).

1.2 PurposeThe quality-assured purpose of the computer software system DBREACH is to perform thecalculations to estimate the time to failure for different dam failure scenarios analyzed todetermine the maximum flood level at specific locations along the Tennessee River, such asat the Bellefonte site.

DBREACH computes the time and rate of failure of earth embankments in the event thatthey are overtopped based on the soil type and the flood hydrograph. In using the resultsof the DBREACH code it is postulated that the assumed failure section disappearsinstantaneously at the calculated failure time. This is a conservative assumption as theactual failure would occur over some period of time. At the time of failure, the SOCHrouting shifts to an after failure rating curve or postulated total failure.

The reference describing the engineering theory used in DBREACH is provided in Reference2. The equation used to compute the rate of erosion in an earth dam failure presented inReference 2 was developed and used by the Bureau of Reclamation in connection with itsdam safety program. This equation relates the volume of eroded fill material to the volumeof water flowing through the breach as a function of the base length of the overtopped partof the dam, the time-dependent hydraulic head, and the angle of friction of the soil materialof the embankment.

1.3 Assumptions and LimitationsThe following postulations are made in the DBREACH code:

1. A breach occurs uniformly over a given length of the dam, implying that the breachoccurs through an elongated rectangular section.

2. Erosion is postulated to occur across the entire earth section of the dam and to startat the downstream edge when the headwater elevation reaches a given depth abovethe dam top elevation. Subsequently, when erosion reaches the upstream edge ofthe embankment, breaching and rapid lowering of the embankment begins.

1



Thereafter, computations include headwater adjustments for increased reservoiroutflow resulting from the breach.

3. The angle of friction used for the soil material of the embankment is constant and is13 degrees, which was adopted for the materials used in the construction of the TVAdams.

4. The material transported by the water due to the sloughing on the side slopes of thebreach is ignored.

DBREACH should be used only to estimate the time of failure of earth embankments, andfor nothing else. For example, it should not be used to predict the outflow hydrographduring an embankment failure. In applying DBREACH, the user is advised to consider firstwhether the postulations that DBREACH is based on are valid in the particular applicationcase (e.g. shape of the breach). In addition the estimated time to failure should be checkedfor reasonableness. For example, if DBREACH estimates a very long time for the failure ofan earth embankment then this estimated time should be reassessed in view of data fromhistorical failures of similar dams. It is recommended that the user of DBREACH do asensitivity analysis for the time of failure.There are also some limitations on data input. For example, each of the following threecurves used by DBREACH must be defined by no more than 20 points:

" Headwater elevation versus time

" Headwater elevation versus discharge

" Headwater elevation versus storage.

Finally, DBREACH does not allow for a berm on the downstream face of the dam. Rather, apoint can be specified where the slope of the downstream face of the dam changes.

These limitations can be addressed by modifying the DBREACH code. Any code modificationmust adhere to the requirements of Section 3.3.2 of Reference 1.

1.4 Computer System Requirements

DBREACH was developed and used by the TVA during the same time frame as SOCH andwas originally run on a mainframe. Later it was transferred to the PC. The latest version ofthe code has been compiled using the Compaq Visual FORTRAN compiler, ProfessionalEdition 6.6A.

DBREACH does not require a significant amount of hard disk space for its executable, input,and output files (well under 1 megabyte). There are also no network limitations identified.

2. DBREACH FUNCTIONALITY

2.1 DBREACH Theoretical Basis

The DBREACH code is used to determine whether an earth embankment overtopped duringa flood will fail and, if so, the time and rate of failure. DBREACH computes the time andrate of failure of earth embankments in the event that they are overtopped based on thesoil type and the flood hydrograph.

2



The equation used to compute the rate of erosion in an earth dam failure presented inReference 2 was developed and used by the Bureau of Reclamation in connection with itsdam safety program. This equation relates the volume of eroded fill material to the volumeof water flowing through the breach as a function of the base length of the overtopped partof the dam, the time-dependent hydraulic head, and the angle of friction of the soil materialof the embankment. Appendix A provides the detailed technical basis and methodology forcalculating (1) the headwater elevation and total flow rate as function of time with damfailure, (2) the flow rate through the breach section as a function of time and (3) theelevation of the top of the dam.

2.2 Input and Output Features

DBREACH uses one input file for all the required input data and produces one output file.

2.2.1 Input Features

To calculate the DBREACH solution for the time of a breach, an input file is needed tocomplete each particular dam break scenario.

In the DBREACH input file, it is necessary to specify the number of runs and the followingkey parameters:

Elevations - Highest elevation of the dam (crest), upstream and downstreamberm elevations, a control elevation that stops the program when erosionreaches that elevation or specifies that erosion goes to completion, andelevation of the base section.

Embankment geometry - Width of the top of the dam and the berm widths(all berms are assumed to have the same width) are input. Slopeinformation includes the angle of friction of the soil embankment; and slopeof the dam crest, upstream and downstream faces above and below theberm.

Erosion and embankment characteristics - The largest erosion depthincrement is specified. Specified embankment characteristics also includethe Weir coefficient and the erosion equation constant

Headwater elevations - Headwater elevations provided in three arrays:headwater elevation versus time values, headwater elevation versusdischarge values, and headwater elevation versus storage values. Thenumber of pairs of each of the three types of input must be specified.

2.2.2 Output Features

The output includes the following data:

An echo of all input data

The headwater elevation and total flow rate as function of time with and withoutdam failure

The flow rate through the breach section as a function of time

The elevation of the top of the dam as a function of time.

Note that DBREACH does not produce an output file in ready-to-plot format, but its outputcan be easily imported in Excel (or other software with plotting capability) and edited to

3



produce plots that illustrate key output data for the embankment failure. For this purposethe output file must first be copied into an Excel spreadsheet. Then the first four lines ineach page of the output file, i.e. the lines containing the header, must be deleted to form acontinuous table of the values of the solution produced by DBREACH.

The following responses to valid and invalid inputs and responses to abnormal situations areproduced by DBREACH:

* When DBREACH functions normally, the following message is printed subsequentto the output for each data set:

"1NORMAL COMPLETION -- RUN (Run Number)"

" If a zero slope is entered , the run terminates. In this case, the output fileconsists only of an echo of the input data and the message:

"1INVALID SLOPE -- MAY NOT EQUAL ZERO"

* The DBREACH code uses linear interpolation to determine values based on theheadwater elevation hydrograph, the elevation vs. discharge relationship, and theelevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If at any time a value to beinterpolated is too small or large for interpolation using these tables, the runterminates and one of the following messages is printed atthe end of the outputfile:

"(Value) IS GREATER THAN MAXIMUM ARRAY VALUE OF -- (Max. Value)"

"(Value) IS LESS THAN MINIMUM ARRAY VALUE OF -- (Min. Value)"

3. PLAN FOR TESTING DBREACH CODE FUNCTIONALITY

3.1 IntroductionThe DBREACH Test Plan must satisfy the requirements of Nuclear Engineering Procedure,SPP-2.6 for computer software system qualification. It consists of comparison of DBREACHtest problems to independent calculations performed in Microsoft Excel, which serves toevaluate the program's capabilities and limitations as related to TVA safety-related designapplications.

The Test Plan associated with DBREACH must be documented in the DBREACH SoftwareVerification and Validation Report (SVVR). Detailed test problem descriptions, results ofeach problem, and a summary of observations and conclusions are provided in the SVVR.The test problems, which are briefly described in Section 3.2 below, are selected to berepresentative of typical TVA applications of the program and to test as many features andoptions as possible.

The test problems must be re-run in the event that major upgrades or total replacement ofthe computer operating system takes place. Any modification to the DBREACH softwareshall be performed in accordance with SPP-2.6 and documented using a Software ServiceRequest (SSR) form. Whenever changes are made to the DBREACH software, anassessment should be made of the impact on operation of DBREACH. The test problemsspecified below must be re-run if certain or potential impact is identified. For minorchanges to the software which do not result in a new system version, either the test

4



problem set must be rerun or a written assessment justifying why the test problems do notneed to be rerun must be provided with the SSR form.

3.2 Test Problems

. Test Problem 1: Failure of Guntersville Dam

This problem is intended to ensure that DBREACH properly solves for the time andrate of failure of an earth embankment experiencing overtopping during a flood usingthe equations proposed by Cristofano (Reference 2) and outlined in Appendix A. Theoutflow flood hydrograph used in this case is of the order of the probable maximumflood (PMF) through the Guntersville reservoir and was obtained by routing throughthe Guntersville Reservoir the PMF and postulating that the dam is overtoppedwithout failing.

0 Test Problem 2: Failure of Guntersville Dam with the slope of the headwaterelevation hydrograph increased by a factor of 2.

This problem is identical to Test Problem 1, with the exception that the slope of theheadwater elevation hydrograph is increased by a factor of 2. This problem isintended to assess the sensitivity of time of failure to the user-specified overtoppingflood elevation hydrograph.

0 Test Problem 3: Failure of Guntersville Dam with the slope of the headwaterelevation hydrograph reduced by a factor of 1.5.

This problem is identical to Test Problem 1, with the exception that the slope of theheadwater elevation hydrograph is reduced by a factor of 1.5. This problem is alsointended to assess the sensitivity of time of failure to the user-specified overtoppingflood elevation hydrograph.

0 Test Problem 4: Failure of Guntersville Dam with an imposed slope on the dam top.

This problem is identical to Test Problem 1, with the exception that a slope of 1:100has been imposed on the top of the dam. This problem is intended to verify thefunctionality of the program feature to model dams without horizontal dam tops.

* Test Problem 5: Failure of Guntersville Dam with a soil constant of proportionalitynot equal to 1.

This problem is identical to Test Problem 1, with the exception that a soil constant ofproportionality [constant K in Equation (1) of Appendix A ] equal to 2 is used. Thisproblem is intended to verify the functionality of the program feature to model damswith other soil constant of proportionality values.

* Test Problem 6: Failure of Guntersville Dam with reservoir storage reduced by afactor of 10.

This problem is identical to Test Problem 1, with the exception that the reservoirstorage volume is reduced by a factor of 10. This problem is intended to verify thelogic used to compute reservoir storage during dam breaching for each time step.

APPENDIX A: DBREACH THEORETICAL BASISDBREACH computes the time and rate of failure of earth embankments during a flood basedon the soil type and period of overtopping (Reference 2). In using the results of theDBREACH code it is postulated that the assumed failure section disappears instantaneouslyat the calculated failure time. This is a conservative assumption as the actual failure wouldoccur over some period of time. At the time of failure the SOCH routing shifts to an afterfailure rating curve or postulated total failure.

The relationship used to compute the rate of erosion in an earth dam failure is thatdeveloped and used by the Bureau of Reclamation in connection with its dam safetyprogram (Reference 2). The expression relates the volume of eroded fill material to thevolume of water flowing through the breach. The equation is:

Q =Ke-x (1)Qw

where:Q, is the volume of soil eroded in each time periodQ, is the volume of water discharged each time periodK is a constant of proportionality; it is equal to 1 for the soil and discharge

relationships used by TVAand

X = b tan OaH (2)

where:b is the base length of the overflow part of the channel (in the direction of the flow)

at any given time

H is the hydraulic head at any given time

Ad is the developed angle of friction of the soil material of the embankment; a

conservative value of 13 degrees was adopted for the materials used for theconstruction of the TVA dams.

Figure 1 illustrates the definition of key parameters used for the analysis of the failure modesimulated by DBREACH

The solution of Equation (1) is achieved by using a trial and error procedure over shortdepth and time increments. DBREACH calculates the rate of soil erosion, Qs, based on anassumed depth of erosion AD over a time period At

Q= A (3)At

where V, is the eroded volume calculated as:

Vs = b AD cosAd (4)

Then from Equations (1) and (3) the time increment can be calculated by:

At = s x

The flow over the breached section is calculated as:

Q1 = CLH3 /

(6)

where

C is a constant

L is the length of the embankment subject to failure

H is the head over the top of the breached section.

In DBREACH, a small depth increment of erosion (Ad), no more than 0.1 ft, is used to keeptime increments to less than one second during rapid failure and up to about 350 secondsprior to breaching.

Figure 1. Schematic illustration of the failure mode simulated by DBREACH

The solution of an earth embankment breach begins by solving the erosion equation using aheadwater elevation hydrograph assuming no failure, as provided by SOCH model outputs.Erosion is postulated to occur across the entire earth section and to start at the downstreamedge when headwater elevations reach a selected depth above the dam top elevation.Subsequently, when erosion reaches the upstream edge of the embankment, breaching andrapid lowering of the embankment begins. Thereafter, computations include headwateradjustments for increased reservoir outflow resulting from the breach.

Equation (1) was developed for an initial condition of flow through an existing notch orbreach of some selected width and is based on the following assumptions (Reference 2):

(a) The bottom width of the notch remains constant and the angle of repose of the fillmaterial is such that the notch shape remains trapezoidal.

(b) The length of the bottom of the overflow channel or shear plane is measured only tothe bedrock strata or selected base elevation. Thus the length of the bottom of the

9



overflow channel increases uniformly to the point where the bedrock inhibits erosion;then the length starts to decrease.

(c) Material transported by the water due to the sloughing of the side slopes in the notchis ignored.

(d) The slope of the bottom of the overflow channel or shear plane is constant and equalto the developed angle of friction of fill material (see Figure 1).

DBREACH uses a different initial condition than that stated above. Instead of assuming anotch to define the initial condition it uses a selected length of the initially unbreachedembankment.

Erosion is postulated to occur across the entire earth section of the dam and to start at thedownstream edge when the headwater elevation reaches a given depth above the dam topelevation. Subsequently, when erosion reaches the upstream edge of the embankment,breaching and rapid lowering of the embankment begins (see Figure 1). Thereafter,computations include headwater adjustments for increased reservoir outflow resulting fromthe breach.

1. INTRODUCTIONDBREACH is a software program used to determine whether an earth embankmentovertopped during a flood will fail and, if so, the time and rate of failure. This information isused by TVA's Simulated Open Channel Hydraulics (SOCH) computer code for flood routingcalculations involving different dam failure scenarios in combination with various floodevents. DBREACH, along with seven other computer codes is used to develop the requiredinput data for SOCH. These computer programs are used to meet United States NuclearRegulatory Commission guidance set forth in Nuclear Regulatory Guide 1.59 (AmericanNational Standards Institute [ANSI] ANSI/ANS-2.8-1992).

2. OVERVIEW OF DESIGNThe DBREACH computer code was designed to provide the input, output, and technicalfeatures described in the SRS [Reference 1]. The software consists of the main programand one subroutine. DBREACH was originally programmed in FORTRAN to run on amainframe computer. It was later transferred to the PC. The current version of the codehas been compiled and linked using the Compaq Visual FORTRAN, Professional Edition 6.6A.The code does not use any external libraries of data files, other than that provided by theuser. The code uses only the subroutine GETARG(1,INFILE,LENGTH) which is one of theCompaq Visual FORTRAN general library routines. This run-time subroutine returns thespecified command-line argument. In addition, the run-time function NARGS() is used.This function returns the total number of command-line arguments, including the command.Finally, several elemental intrinsic functions are used. Theses functions are listed andexplained as follows. DATAN(x) produces the arctangent of x. DSIN(x) produces the sineof x. DCOS(x) produces the cosine of x. DTAN(x) produces the tangent of x. DABS(x)produces the absolute value of x. DEXP(x) computes the exponential value ex.

DBREACH has a simple user interface imbedded in the main program. The user interface isall under the COMMAND prompt. It asks the user for the input and output file names. Thecode uses only one input file and produces one output file.

DBREACH computes the time and rate of failure of earth embankments from overtoppingbased on the embankment geometry, soil type, and the flood elevation hydrograph. It usesthe method developed and used by the Bureau of Reclamation in connection with its damsafety program, which is documented in Reference 2. The equations solved by DBREACHare:

O_ =Ke-X (1)

X= tan ~dH (2)

Qw = CLHJ312 (3)

where:Q, is the volume of soil eroded in each time periodQ, is the volume of water discharged each time periodK is a constant of proportionality; it is equal to 1 for the soil and discharge

relationships used by TVA

1



b is the base length of the overflow part of the channel (in the direction of the flow)at any given time

H is the hydraulic head at any given time

Od is the developed angle of friction of the soil material of the embankment; a


C is a constant


DBREACH solves Equations (1) through (3) by advancing the dam erosion calculation insteps specifying the erosion depth, Ad, at each step. Based on the erosion depth, Ad, andthe geometry of the embankment and the breach section it is possible to estimate thevolume, V,, that corresponds to the erosion depth Ad. Then the time period At thatcorresponds to erosion of the embankment by depth Ad can be calculated as a function ofVs. As explained in the User's Manual for DBREACH, Version 1.0 (Reference 3), the timeincrement, At, is given by the equation:

At- = ex (4)KQý

DBREACH uses a variable Ad over time. It allows Adto vary with time between an uppervalue limit specified by the user (represented by the input variable DELTD defined in Section4.1 of Reference 3), and a lower value limit calculated by DBREACH based on the rate ofwater level change in the reservoir. The purpose of using a variable Ad in DBREACH is toreduce the computer time required to obtain the solution of the dam erosion equation, whileensuring the accuracy of the solution.The main program of the DBREACH code implements the solution scheme described above.It uses one subroutine, the subroutine INTERP(VAL,AR1,AR2,L,M,MAX,RES,*) whichinterpolates between the values of an array. This subroutine is invoked twice at every stepof the solution process

a) to estimate the headwater (reservoir) elevation as a function time from user providedtable of headwater levels vs. time for the case of no dam failure, and

b) to estimate the total discharge through all outlets as a function of the headwaterelevation.

3. INPUT AND OUTPUT FEATURESDBREACH uses one input file and one output file, which are associated with specific Unitnumbers in the standard FORTRAN language terminology (e.g. Unit 5 for reading data, unit6 for printout, etc).

Input:

* Unit 5: INFIL - The main input file where the input parameters are provided.

Output:

0 Unit 6: OUTFIL - The standard file for printed output.

2



DBREACH does not produce an output file in ready-to-plot format, but its output can beeasily imported in Excel (or other software with plotting capability) and edited to produceplots that illustrate key output data for the embankment failure.

For this purpose the output file must first be copied into an Excel spreadsheet. Then thefirst four lines in each page of the output file, i.e. the lines containing the header, must bedeleted to form a continuous table of the values of the solution produced by DBREACH.

3.1 Input FeaturesTo calculate the DBREACH solution for the time of a breach, an input file is needed tocomplete each particular dam break scenario.

In the DBREACH input file, it is necessary to specify the number of runs and the followingkey parameters:

* Elevations - Highest elevation of the dam (crest), upstream and downstreamberm elevations, a control elevation that stops the program when erosionreaches that elevation or specifies that erosion goes to completion, andelevation of the base section.

Embankment geometry -Width of the top of the dam and the berm widths(all berms are assumed to have the same width) are input. Slopeinformation includes the angle of friction of the soil embankment; and slopeof the dam crest, upstream and downstream faces above and below theberm.

Erosion and embankment characteristics - The largest erosion depthincrement is specified. Specified embankment characteristics also includethe Weir coefficient and the erosion equation constant

Headwater elevations - Headwater elevations provided in three arrays:headwater elevation versus time values, headwater elevation versusdischarge values, and headwater elevation versus storage values. Thenumber of pairs of each of the three types of input must be specified.

3.2 Output FeaturesDBREACH does not produce an output file in ready-to-plot format, but its output can beeasily imported in Excel (or other software with plotting capability) and edited to produceplots that illustrate key output data for the embankment failure.

For this purpose the output file must first be copied into an Excel spreadsheet. Then thefirst four lines in each page of the output file, i.e. the lines containing the header, must bedeleted to form a continuous table of the values of the solution produced by DBREACH.

The output includes the following data:

" An echo of all input data

* The headwater elevation and total flow rate as function of time with and withoutdam failure

* The flow rate through the breach section as a function of time

" The elevation of the top of the dam as a function of time.

3



The following responses to valid and invalid inputs and responses to abnormal situations areproduced by DBREACH:

o When DBREACH functions normally, the following message is printed subsequentto the output for each data set:

"INORMAL COMPLETION -- RUN (Run Number)"

* If a zero slope is entered for SS1, SS2, SS3, SSL1, or SSL2, the run terminates.In this case, the output file consists only of an echo of the input data and themessage:


" The DBREACH code uses linear interpolation to determine values based on theheadwater elevation hydrograph, the elevation vs. discharge relationship, and theelevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If at any time a value to beinterpolated is too small or large for interpolation using these tables, the runterminates and one of the following messages is printed at the end of the outputfile:

1. INTRODUCTION

1.1 Background

The computer program DBREACH is used to determine whether an earth embankmentovertopped during a flood will fail and, if so, the time and rate of failure. This information isused by the Simulated Open Channel Hydraulics (SOCH) computer code for flood routingcalculations involving different dam failure scenarios in combination with different floodevents. The purpose of these calculations is to determine the maximum flood level atspecific locations along the river, such as the Bellefonte site.

DBREACH was developed and used by the Tennessee Valley Authority (TVA) during thesame timeframe as SOCH and was originally run on a mainframe computer. Later,DBREACH was transferred to the personal computer (PC).

1.2 Scope

This report documents the DBREACH code functionality testing as defined by Reference 1,Section 3 and by Reference 2, Appendix G. This report is limited to verifying the numericalsolutions of the equations used and solved by DBREACH. The theoretical basis of the codeand the equations it solves are described in Reference 3, published in 1966, and aredescribed in Reference 1, Appendix A.

This report does not address the question of the validity of the equations presented inReference 3 in terms of their accuracy in predicting the time to failure compared withhistoric embankment breaches. The literature on the subject of earthfill dam failures since1966, the year of the publication of Reference 3, is extensive. It is recommended that theestimated time to failure should be checked for reasonableness. For example, if DBREACHestimates a very long time for the failure of an earth embankment then this estimate shouldbe reassessed in view of data from historical failures of similar dams. It is alsorecommended that the user of DBREACH analyzes the sensitivity of the estimated time tofailure to values of the different input parameters used in this estimate.

Section 2 of this document describes the plan for testing the DBREACH functionality.Section 3 describes the results of the tests of the DBREACH code. Section 4 gives thesummary and conclusions of the DBREACH functionality testing. References are listed inSection 5.

2. PLAN FOR TESTING DBREACH FUNCTIONALITY

2.1 OverviewThe DBREACH Test Plan consists of a comparison of the solution of several test problemsobtained with DBREACH to independent calculations. The test plan serves to evaluate theprogram's capabilities and limitations as related to TVA design applications. The testproblems, which are described in Section 2.2, were selected to be representative of typicalTVA applications of the program.

Changes or modifications to the DBREACH computer program shall be documented asrequired in Section 3.3 of Reference 2.

The test problems specified herein are intended to assess the extent of possible programfeatures and options likely to be required for safety-related design analysis.

2.2 Problems to Test DBREACH Functionality* Test Problem 1: Failure of the Guntersville Dam

This problem is intended to ensure that DBREACH properly solves for the time andrate of failure of an earth embankment experiencing overtopping during a flood usingthe equations proposed by Cristofano (Reference 3) as required by the DBREACHSoftware Requirements Specification (Reference 1) and as outlined in the DBREACHUser's Manual (Reference 4). The representative outflow flood hydrograph used inthis test case is of the order of the probable maximum flood (PMF) through theGuntersville reservoir and was obtained by routing through the GuntersvilleReservoir a preliminary estimate of the PMF and postulating that the dam isovertopped without failing (see Reference 5 for input data).Guntersville Dam (Figure 1) is the representative dam used in Test Problem 1.Figure 2 gives the headwater hydrograph for the same problem. Figure 3 and Figure4 give, respectively, the discharge rating curve and the storage capacity curve usedin this problem. All data used in Test Problem 1 are from Reference 7.

a Test Problem 2: Failure of the Guntersville Dam with the slope of the headwaterelevation hydrograph increased by a factor of 2.

This problem is identical to Test Problem 1, with the exception that the slope of theheadwater elevation hydrograph is increased by a factor of 2. This problem isintended to assess the sensitivity of the time of failure to the user-specifiedovertopping elevation hydrograph.

" Test Problem 3: Failure of the Guntersville Dam with the slope of the headwaterelevation hydrograph reduced by a factor of 1.5.

This problem is identical to Test Problem 1, with the exception that the slope of theheadwater elevation hydrograph is reduced by a factor of 1.5. In addition, the inputheadwater elevation versus time relationship was extrapolated beyond the last timedefined in Test Problem 1 in order to accommodate the longer time to failure for thisproblem. This problem is also intended to assess the sensitivity of time of failure tothe user-specified overtopping elevation hydrograph.

" Test Problem 4: Failure of the Guntersville Dam with an imposed slope on the damtop.

This problem is identical to Test Problem 1, with the exception that a slope of 1:100is imposed on the top of the dam. This slope is represented by the input parameterSS1 in the DBREACH code, which is defined in Section 4.1 of Reference 4. Thisproblem is intended to verify the functionality of the program feature to model damswithout horizontal dam tops.

* Test Problem 5: Failure of the Guntersville Dam assuming that the soil constant ofproportionality is not equal to 1.

4



This problem is identical to Test Problem 1, with the exception that a soil constant ofproportionality [constant K in Equation (1) of Reference 4] equal to 2 is used. Thissoil constant is represented by the input parameter SOILK in the DBREACH codedefined in Section 4.1 of Reference 4. This problem is intended to verify thefunctionality of the program feature to model dams with values of the soil constantof proportionality other than 1.

0 Test Problem 6: Failure of the Guntersville Dam with the reservoir storage reducedby a factor of 10.

This problem is identical to Test Problem 1, with the exception that the reservoirstorage volume is reduced by a factor of 10. This means that all the values of thearray C3STOR in the DBREACH code, defined in Section 4.1 of Reference 4, are 10times smaller than those used in the previous test problems. This problem isintended to verify the logic used to compute reservoir storage during dam breachingfor each time step.

2.3 Solution Method Used in the Independent Calculations

The independent calculations use the same general method for the solution of the basicerosion equation given in Reference 3 as DBREACH.

The dam erosion calculation advances in steps specifying the erosion depth, Ad, at eachstep. Based on the erosion depth, Ad, and the geometry of the embankment and thebreach section it is possible to estimate the volume, V,, that corresponds to the erosiondepth Ad. Then the time period At that corresponds to erosion of the embankment by depthAd can be calculated as a function of Vs. As explained in the DBREACH User's Manual(Reference 4), the time increment, At, is given by the equation:

At = e (1)KQw

where:

V, is the volume of soil eroded over a time period At

Qwv is the volume of water discharged each time period through the breached sectionof the dam

K is a constant of proportionality; it is equal to 1 for the soil and dischargerelationships used by TVA

and

X = - tan dH (2)


at any given timeH is the hydraulic head over the breached section at any given time

SOFTWARE VERIF[CATION AND VALIDATION REPORT (SVVR) Revision 1


od is the developed angle of friction of the soil material of the embankment; a


The flow over the breached section is calculated as (Reference 6):

Qw = CLH3/2 (3)

where

C is a constant


DBREACH uses a variable Ad over time. It allows Adto vary with time between an uppervalue limit specified by the user (represented by the input variable DELTD defined in Section4.1 of Reference 4), and a lower value limit calculated by DBREACH based on the rate ofwater level change in the reservoir. The purpose of using a variable Ad in DBREACH is toreduce the computer time required to obtain the solution of the dam erosion equation, whileensuring the accuracy of the solution.

The independent Excel-based calculation used to validate DBREACH uses a constant depthincrement Ad. To check the adequacy of the size of Ad Test Problem 1 was solved usingthree different values of Ad. These solutions are given in Table 1 together with the solutionobtained with DBREACH.

Table 1. Effect of Ad on the Estimated Time to Failure

12.91 17.78 0.05 12.93 17.80

0.01 12.86 17.79

As can be seen in Table 1 the estimated time converges as the Ad decreases. The solutionsfor the three different erosion increments Ad, 0.01, 0.05 and 0.01, were obtained using theExcel spreadsheets "DamBreach-samplel_0.10.xls", "DamBreach-samplel_0.05.xls" and"DamBreach-samplel_0.01.xls" respectively. These spreadsheets are included in ElectronicAttachment 4.

For comparison purposes it is noted that DBREACH in solving the same problem uses a Adthat varies between 0.018 ft and 0.1 ft. DBREACH uses a variable Ad in order to decreasethe program run time. In the independent Excel-based calculations the constant Ad valuewas picked such that it is always smaller than the Ad used by DBREACH. Therefore, theindependent calculations produce more accurate results than those obtained by DBREACH.

The results of DBREACH for Test Problem 1 are also validated by programming the exactsame logic used by DBREACH in an Excel spreadsheet. This spreadsheet solution uses the

6



same rules to vary Ad as DBREACH. The estimated time to failure obtained this way isidentical to that produced by DBREACH. The name of the spreadsheet used for this purposeis "DBreachRevl.xls" and it is included in Electronic Attachment 4.

Plots of the dam and reservoir behavior during breaching were prepared to compare theresults obtained from DBREACH and the independent calculations.

Figure 5 and Figure 6 show the simulated water surface elevation as a function of time forTest Problem 1 as calculated by DBREACH and the independent calculations, respectively.Figure 7 and Figure 8 show the simulated flow through the failure section and the total flowas a function of time for Test Problem 1 as calculated by DBREACH and by the independentcalculations, respectively. Figure 9 and Figure 10 show the dam top elevation as a functionof time for Test Problem 1 as calculated by DBREACH and the independent calculations,respectively. These figures show that the results of DBREACH for Test Problem 1 arepractically identical to those of the independent calculations. The DBREACH solution showsthat the breaching of the dam begins at about 12.91 hours and the embankment failscompletely after 17.64 hours. The estimated time for the beginning of the dam breach with

8



the independent Excel calculations is 12.86 hours and the time to complete failure is 17.65hours.

Figure 11 through Figure 16 show similar plots for Test Problem 2, which is similar to TestProblem 1 with the exception of the slope of the headwater elevation hydrograph, which isequal to twice the slope of the hydrograph used in Test Problem 1. As can be seen in thesefigures, the results of DBREACH for Test Problem 2 are practically identical to those of theindependent calculations. DBREACH estimates that the breaching of the dam begins at 6.93hours and the embankment fails completely after 9.74 hours. The estimated time for thebeginning of the dam breach with the independent Excel calculations is 6.90 hours and thetime to complete failure is 9.74 hours.

Figure 17 through Figure 22 show the results for Test Problem 3, which is similar to TestProblem 1 with the exception of the slope of the headwater elevation hydrograph, which isequal 1.5 times smaller than the slope of the hydrograph used in Test Problem 1. As can beseen in these figures, the results of DBREACH for Test Problem 3 are practically identical tothose of the independent calculations. DBREACH estimates that the breaching of the dambegins at 19.44 hours and the embankment fails completely after 26.35 hours. Theestimated time for the beginning of the dam breach with the independent Excel calculationsis 19.44 hours and the time to complete failure is 26.37 hours.

Figure 23 through Figure 28 show the results for Test Problem 4, which is similar to TestProblem 1 with the exception of the slope of the top of dam, which is 1:100 instead of zeroin Test Problem 1. As can be seen in these figures, the results of DBREACH for TestProblem 4 are practically identical to those of the independent calculations. The dam failurebegins at time zero in both calculations, and it is complete after 16.85 hours according toDBREACH and after 16.87 hours in the independent Excel calculations.

Figure 29 through Figure 34 show the results for Test Problem 5, which is similar to TestProblem 1 with the exception of the soil constant SOILK which is equal to 2 in Test Problem5 instead of 1 in Test Problem 1. As can be seen in these figures, the results of DBREACHfor Test Problem 5 are practically identical to those of the independent calculations.DBREACH estimates that the breaching of the dam begins at 12.01 hours and theembankment fails completely after 15.41 hours. The estimated time for the beginning ofthe dam breach with the independent Excel calculations is 11.96 hours and the time tocomplete failure is 15.42 hours.

Figure 35 through Figure 40 show the results for Test Problem 6, which is similar to TestProblem 1 with the exception of the storage capacity of the reservoir which is 10 timessmaller than in Test Problem 1. Again these figures show that the results of DBREACH forTest Problem 6 are practically identical to those of the independent calculations. DBREACHestimates that the breaching of the dam begins at 12.91 hours. The independent Excelcalculation predicts that the breaching of the dam begins at 12.86 hours. The time tocomplete failure in this case is longer, estimated to be 34.90 hours by DBREACH and 34.86hours by the independent calculations.

Table 3 summarizes the calculated times for the beginning of the dam breach and thecomplete collapse of the embankment obtained with DBREACH and with the independentcalculations for each of the six test problems.

6 12.91 23.32 12.86 23.34

The DBREACH results are in good agreement with the results obtained through independentcalculation for all Test Problems. The small differences in the estimated time to failure byDBREACH and the independent calculations are due to the use of a constant Ad in theindependent calculations as opposed to the variable Ad used by DBREACH. It is noted thatDBREACH produces a little shorter time to failure (by 0.02 hrs = 1.2 minute or less), i.e. itgives a little more conservative solution.

3.2 Response of DBREACH to Abnormal Input Data

DBREACH has built-in safeguards to warn users when abnormal situations arise duringoperation of the program. A listing of these safeguards is provided below.

" If a zero value is entered for the slopes represented by the variables SS1, SS2,SS3, SSL1, or SSL2 (as defined in Reference 4), the run terminates. In this case,the output file consists only of an echo of the input data and the message:


* The DBREACH code uses linear interpolation to determine values based on theheadwater elevation hydrograph, the elevation vs. discharge relationship, and theelevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If at any time a value to beinterpolated is too small or large for interpolation using these tables, the runterminates and one of the following messages is printed at the end of the outputfile:



If none of the above abnormal conditions occurs, DBREACH is presumed to have functionednormally. In this case, the following message is printed subsequent to the output for eachdata set:

"1NORMAL COMPLETION -- RUN (Run Number)"

However, it is possible for DBREACH to appear to have functioned normally while usinginvalid input data. A few such cases are presented below:

10



" Consecutive KIDAY values that differ by more than 1:

Table 2 of Reference 4 states that "no two consecutive KIDAY values shoulddiffer by more than 1." However, DBREACH was executed using consecutiveKIDAY values that differ by more than one and the program terminatednormally.

" KIHOUR and KIMIN values out of range:

Table 2 of Reference 4 states that KIHOUR values should be between 0 and 23while KIMIN values should be between 0 and 59. In some cases when runningDBREACH with values outside of the acceptable range DBREACH will functionnormally; however in some cases it will not, as seen in Table 4 below.

Table 4. Comparison of Valid DBREACH Input andEquivalent Invalid Input

Correct Input Abnormal Input DBREACHK output the

KIDAY KIHOUR KIMIN KIDAY KIHOUR KIMIN same?28 0 40 27 24 40 Yes28 4 30 28 3 90 Yes27 21 0 28 -3 0 Yes27 12 0 28 -12 0 NO

In the last case listed in Table 4 (where the DBREACH output files for the correctand the abnormal output are not the same), the two output files begin to divergeat KIDAY=28, KIHOUR=12, K1MIN=0. Then, when the second file reachesKIDAY=28, KIHOUR=23, KIMIN=59, the time counter is reset to K1DAY=1,KIHOUR=0, K1MIN=0.

* Paired data not in order from smallest to largest:

As stated above, DBREACH uses linear interpolation to determine values basedon the headwater elevation hydrograph, the elevation vs. discharge relationship,and the elevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If any of these paired datasets is not entered in order from smallest to largest, the interpolation scheme willdisregard smaller data points placed after the larger values. Therefore, theDBREACH code will not use all of the input data and the output will be differentthan if the paired data was entered in sequential order.

In the cases presented in this section, DBREACH accepts invalid input data but does notwarn the user that the data are invalid. In some cases DBREACH may produce correctresults with invalid data, but in other cases it does not. In addition, there may be moreexamples of invalid data which result in normal termination of DBREACH besides thosepresented above. Therefore, it is the responsibility of the user to confirm that the inputdata file is valid in order to ensure that the DBREACH output is also valid. Normaltermination of DBREACH is a necessary but not sufficient condition for producing validresults.

11



4. SUMMARY AND CONCLUSIONSFor all Test Problems specified in Reference 1, the results from DBREACH are in goodagreement with the results obtained through independent calculations using MicrosoftEXCEL. The differences between the two solutions are attributed to the use of a constantAd in the independent calculations as opposed to the variable Ad used by DBREACH.

Based on the results of all the test problems, the DBREACH software is validated andverified for use.

However, it is important that the user verifies that the input data are valid (as defined inSection 4 of Reference 4) as DBREACH can terminate normally in some cases using invaliddata and producing erroneous output without warning the user.

In addition, the work presented in this report is limited to the verification and validation ofthe numerical solutions of the equations used and solved by DBREACH. The equations usedin DBREACH are based on Reference 3 and are consistent with the Software RequirementsSpecification (Reference 1). It is beyond the scope of this SVVR to assess the ability of thismethodology to accurately predict the time of failure. It is recommended that the useraddresses the uncertainty in the time to failure estimated by DBREACH by performing inputparameter sensitivity analyses.

1. INTRODUCTION

.1.1 The TVA SOCH Suite of Computer Codes

The computer program DBREACH is used to determine whether an earth embankmentovertopped during a flood will fail and, if so, the time and rate of failure. This information isused by the Simulated Open Channel Hydraulics (SOCH) computer code for flood routingcalculations involving different dam failure scenarios in combination with different floodevents. The purpose of these calculations is to determine the maximum flood level atspecific locations along the river, such as the Bellefonte site.

DBREACH was developed and used by the Tennessee Valley Authority (TVA) at the sametime as SOCH and was originally run on a mainframe computer. Later DBREACH wastransferred to the personal computer (PC).

DBREACH is one of seven computer codes used to develop the required input data forSOCH. The other six codes are: UNITGRPH, FLDHYDRO, TRBROUTE, CHANROUT, CONVEY,and WWIDTH. Table 1 gives a brief description of the seven codes used together withSOCH.

Table 1 Summary of TVA's flood analysis codes

Computer Code Description

UNITGRPH Computes unit hydrograph for each sub area from historical flooddata.

FLDHYDRO Determines inflow from unit hydrographs and rainfall.

TRBROUTE Routing of hydrograph from one point to another using differentrouting procedures.

CHANROUT Determines routing method coefficibnts.

DBREACH Determines earth embankment failure time based on soil typeand period of overtopping during a flood.

WWIDTH Determines equivalent weighted width (B) to account forreservoir volume in SOCH geometry.

CONVEY Determines cross sectional area (A) and composite hydraulicradius raised to the 2/3 power (R2/ 3) for SOCH geometry.

SOCH One dimensional unsteady flow model that computes elevation,discharge, and average velocity at selected locations.

Section 2 of this document describes the theoretical basis of DBREACH, including itsmathematical formulation. Section 3 describes the DBREACH code and provides step-by-step instructions on how to use it. Section 4 gives the definition of all the input variablesrequired to run DBREACH and discusses an example of a typical input file. Section 5discuses the output produced by DBREACH, and plots of key results. The references cited inthis document are listed in Section 6. Appendix A provides a listing of the DBREACH sourcecode, Appendix B presents an example of a typical input file, and Appendix C presents thelisting of the output obtained from a typical problem.

1.2 Limitations on Use

DBREACH should be used only for estimating the time of failure of earth embankments. Forexample it should not be used to predict the outflow hydrograph during an embankmentfailure.

In applying DBREACH, the user is advised to consider first whether the postulations thatDBREACH is based on are valid, in the particular application case (e.g. shape of the breach).In addition, the estimated time to failure should be reviewed for reasonableness. Forexample, if DBREACH estimates a very long time for the failure of an earth embankmentthen the estimated time should be reassessed in view of data from historical failures ofsimilar dams. It is recommended that the user of DBREACH do an input parametersensitivity analysis for the time of failure.Some limitations on the input data are discussed in Section 4.1. For example, each of thefollowing three curves used by DBREACH must be defined by no more than 20 points:

* Headwater elevation versus time

" Headwater elevation versus discharge

" Headwater elevation versus storage.

1.3 Maintenance and User Support

The DBREACH application owner is the Nuclear Power Group (NPG) Corporate CivilEngineering. User support needs will be arranged through the NPG Corporate CivilEngineering with the technically cognizant TVA organization or vendor. Any problemsidentified with the software should be reported to NPG Corporate Civil Engineering.

2. THEORETICAL BASISDBREACH computes the time and rate of failure of earth embankments during a flood basedon the soil type and period of overtopping (Reference 2). In using the results of theDBREACH code it is postulated that the assumed failure section disappears instantaneouslyat the calculated failure time. This is a conservative assumption as the actual failure wouldoccur over some period of time. At the time of failure the SOCH routing shifts to an afterfailure rating curve or postulated total failure.

The relationship used to compute the rate of erosion in an earth dam failure is thatdeveloped and used by the Bureau of Reclamation in connection with its dam safetyprogram (Reference 2). The expression relates the volume of eroded fill material to thevolume of water flowing through the breach. The equation is:

Q-=Ke-x (1)

where:Q, is the volume of soil eroded in each time periodQý is the volume of water discharged each time periodK is a constant of proportionality; a value of 1 is used for the soil and discharge

relationships used by TVAand

X= b tanbdH (2)


at any given time, measured on the erosion plane which is inclined at thedeveloped angle of friction, Od.

H is the hydraulic head over the top of the breached section at any given time

Od is the developed angle of friction of the soil material of the embankment; aconservative value of 13 degrees was adopted for the materials used for theconstruction of the TVA dams.

Figure 2 illustrates the definition of key parameters used for the analysis of the failure modesimulated by DBREACH.

The solution of Equation (1) is achieved by using a trial and error procedure over shortdepth and time increments. DBREACH calculates the rate of soil erosion, Q,, based on anassumed depth of erosion Ad over a time period At

Q, =v, (3)At

where V, is the eroded volume calculated as:

V, = b Ad cos d (4)

4



Then from Equations (1) and (3) the time increment can be calculated by:

At= eXKQw

The flow over the breached section is calculated as (Reference 3):

Qw = CLH 3/2

(5)

(6)

where

C is a constant

L is the length of the embankment subject to failure; L is measured in the directionnormal to the direction of flow.

In DBREACH, a small depth increment of erosion (Ad), no more than 0.1 ft, is used to keeptime increments to less than one second during rapid failure and up to about 350 secondsprior to breaching.

Figure 2. Schematic illustration of the failure mode simulated by DBREACH

The solution of an earth embankment breach begins by solving the erosion equation using aheadwater elevation hydrograph assuming no failure, as provided by SOCH model outputs.Erosion is postulated to occur across the entire earth section and to start at the downstreamedge of the top of the dam when headwater elevations reach a selected depth above the topof the dam. Subsequently, when erosion reaches the upstream face of the embankment,breaching and rapid lowering of the embankment begins. Thereafter, computations includeheadwater adjustments for increased reservoir outflow resulting from the breach.

Equation (1) was developed for an initial condition of flow through an existing notch orbreach of some selected width and is based on the following assumptions (Reference 2):

(a) The bottom width of the notch remains constant and the angle of repose of the fillmaterial is such that the notch shape remains trapezoidal. In DBREACH thebreached portion of the dam is assumed to be rectangular.

5



(b) The length of the bottom of the overflow channel or shear plane, represented by thevariable b in Equation (2), is measured only to the bedrock strata or a selected baseelevation. Thus the length of the bottom of the overflow channel increases uniformlyuntil the edge of the erosion plane reaches the point B in Figure 2, where thebedrock inhibits further erosion; then the length of the erosion plane (b) starts todecrease.

(c) Material transported by the water due to the sloughing of the side slopes in the notchis ignored.

(d) The slope of the bottom of the overflow channel or shear plane is constant and equalto the developed angle of friction of fill material (see Figure 2).

DBREACH uses a different initial condition than that stated above. Instead of assuming anotch to define the initial condition it uses the length of the embankment subject to failure.

Erosion is postulated to occur across the section of the dam subject to failure and to start atthe downstream edge when the headwater elevation reaches a given depth above the damtop elevation. Subsequently, when erosion reaches the upstream edge of the embankment,breaching and rapid lowering of the embankment begins (see Figure 2). Thereafter,computations include headwater adjustments for increased reservoir outflow resulting fromthe breach.

3. THE DBREACH CODE AND HOW TO RUN IT

3.1 The DBREACH code

DBREACH was originally programmed to run on a mainframe computer and was latertransferred to the PC. Version 1.0 of the code has been compiled using the Compaq VisualFORTRAN, Professional Edition 6.6A.

The DBREACH code consists of the main program and the subroutineINTERP(VAL,AR1,AR2,L,M,MAX,RES,*) which interpolates between the values of an array. Acomplete listing of the DBREACH source code is given in Appendix A.

The DBREACH documentation, verification/validation, configuration control and cybersecurity requirements shall meet the requirements of Reference 1.

3.2 How to run DBREACH

To run DBREACH on a Windows PC go through the following steps:

1. Create a shortcut of the executable "DBREACH.EXE"2. Copy that shortcut to the Desktop.3. Right button click the shortcut icon and choose "Properties".4. Change the "Start in:" folder to the folder containing the DBREACH input

dataset(s).5. Double click on the DBREACH shortcut icon6. When prompted, provide the name of the input and the output files.

An example of the interactive session for running DBREACH is given below:

ach~ex

7



When the execution window disappears, DBREACH has run and produced the output fileGuntersville.out, which is located in the same folder as the input data file. The contents ofthis file as well as the contents of the user-provided input file Guntersville.dat are discussedin detail in Sections 4 and 5.

4. INPUT DATA

4.1 Description of Input Variables

DBREACH uses one input file and one output file, which are associated with specific unitnumbers in the standard FORTRAN language terminology (e.g. unit 5 for reading data, unit6 for printout).

Input:

0 Unit 5: INFIL - The main input file where the input parameters are provided.

Output:

* Unit 6: OUTFIL - The standard file for printed output.

Table 2 gives the definition of the input variables and their format in the input file toDBREACH. All elevations and dimensions should be entered in feet.

The designations used to describe the format of the input data in Table 2 are the standarddesignations used in FORTRAN. The designations "F" and "I" are used to indicate floatingpoint and integer numbers respectively. They are followed by a number that indicates thenumber of characters in each field, and preceded by a number indicating how many times afield is repeated, i.e. how many such numbers are entered sequentially in the same line.For example, 819 indicates 8 fields, each of which contains an integer number 9 characterslong. An integer number should be placed at the right end of the corresponding field.Blanks after any numbers are interpreted as zeros. For example, if the format is 19, and thedata file contains the number 55 preceded by 7 blanks, the program will read it correctly.If, however, the number 55 is shifted within the 9-character field in such a way as it ispreceded by 6 blanks and followed by a blank, then the program will read it as 550, becauseit will interpret the last blank as zero. The floating point number designation indicates alsohow many significant decimal digits follow the decimal point. For example, the format8F9.2 indicates that they are 8 numbers, each of which can be as long as 9 characters, thelast two of which are decimal digits. The letter "A" in the format column is the formatdesignation of a single character alphanumeric variable. If the letter "A" is followed by anumber, this number indicates the number of characters in the alphanumeric variable. Ifthe letter "A" is preceded by number, then this number is the number of alphanumericvariables read sequentially. For example the format 18A4 indicates 18 alphanumericvariables consisting of 4 characters each. These variables can be the elements of an arraycontaining a specific piece of text, like a title, as is the case of line 2 in Table 2.

4.4 Response of DBREACH to Abnormal Input DataDBREACH has built-in safeguards to warn users when abnormal situations arise duringoperation of the program. A listing of these safeguards is provided below.

" If a zero value is entered for the slopes represented by the variables SS1, SS2,SS3, SSL1, or SSL2 (as defined in Section 4.1), the run terminates. In this case,the output file consists only of an echo of the input data and the message:


" The DBREACH code uses linear interpolation to determine values based on theheadwater elevation hydrograph, the elevation vs. discharge relationship, and theelevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If at any time a value to beinterpolated is too small or large for interpolation using these tables, the runterminates and one of the following messages is printed at the end of the outputfile:



If none of the above abnormal conditions occurs, DBREACH is presumed to have functionednormally. In this case, the following message is printed subsequent to the output for eachdata set:

"INORMAL COMPLETION -- RUN (Run Number)"

However, it is possible for DBREACH to appear to have functioned normally while usinginvalid input data. A few such cases are presented below:

" Consecutive KIDAY values that differ by more than 1:

Table 2 states that "no two consecutive KIDAY values should differ by more than1." However, DBREACH was executed using consecutive KIDAY values that differby more than one and the program terminated normally.

" KIHOUR and KIMIN values out of range:

Table 2 states that KIHOUR values should be between 0 and 23 while KIMINvalues should be between 0 and 59. In some cases when running DBREACH withvalues outside of the acceptable range DBREACH will function normally; howeverin some cases it will not, as seen in Table 3 below.

In the last case listed in Table 3 (where the DBREACH output files for the correctand the abnormal output are not the same), the two output files begin to divergeat KIDAY=28, KIHOUR=12, K1MIN=0. Then, when the second file reaches

15



K1DAY=28, KIHOUR=23, K1MIN=59, the time counter is reset to K1DAY=1,K1HOUR=O, K1MIN=O.

Paired data not in order from smallest to largest:

As stated above, DBREACH uses linear interpolation to determine values basedon the headwater elevation hydrograph, the elevation vs. discharge relationship,and the elevation vs. storage relationship provided in the input file in the form ofelevation-discharge and elevation-storage tables. If any of these paired datasets is not entered in order from smallest to largest, the interpolation scheme willdisregard smaller data points placed after the larger values. Therefore, theDBREACH code will not use all of the input data and the output will be differentthan if the paired data was entered in sequential order.

In the cases presented in this section, DBREACH accepts invalid input data but does notwarn the user that the data are invalid. In some cases DBREACH may produce correctresults with invalid data, but in other cases it does not. In addition, there may be moreexamples of invalid data which result in normal termination of DBREACH besides thosepresented above. Therefore, it is the responsibility of the user to confirm that the inputdata file is valid in order to ensure that the DBREACH output is also valid. Normaltermination of DBREACH is a necessary but not sufficient condition for producing validresults.

5. OUTPUT DATASection 5.1 references an example of the output produced by DBREACH and Section 5.2discusses how these data can be plotted to obtain a graphical representation of the solutionproduced by DBREACH

5.1 Example of output fileThe output file (written out in Unit 6) produced by running DBREACH for the examplepresented in Appendix B is listed in Appendix C. The first line of the output gives theversion number of the DBREACH code and the date it was issued..

5.2 Plotting the output dataDBREACH does not produce an output file in ready-to-plot format, but its output can beeasily imported in Excel (or other software with plotting capability) and edited to produceplots that illustrate key output data for the embankment failure.

For this purpose the output file must first be copied into an Excel spreadsheet. Then thefirst four lines in each page of the output file, i.e. the lines containing the header, must bedeleted to form a continuous table of the values of the solution produced by DBREACH.(The first line of each new page in the output file is the line that starts with the number"1"). An example of such editing of the output data is given in Table 4. The values in Table4 are those given in the output file presented in Appendix C. Because it is used only toillustrate the concept, Table 4 includes only several lines from the beginning and from theend of the solution produced by DBREACH for the example presented in Appendix B.

Figure 5 shows the simulated water level elevation with and without failure as a function oftime for the previous example. The times given are measured from the beginning of thesimulation, i.e. 9 am of day 27. The'curves shown in Figure 5 were produced by plottingcolumn (4) vs. column (11), and column (6) vs. column (11) in Table 4.

Figure 6 shows the simulated total flow and the flow through the failure section. Figure 7shows the top elevation of the dam during failure. As can be seen in the output file listed inAppendix C, the top of the dam starts being eroded after 12.91 hours from the beginning ofthe simulation. The curves shown in Figure 6 were produced by plotting column (7) vs.column (11), and column (8) vs. column (11) in Table 4.

Figure 7 shows that the rate of the erosion of the top becomes higher around hour 16 andthe embankment totally collapses at hour 17.78. The simulation stops when the top of thedam reaches a predetermined elevation (ELMIN), which is in this example was selected aselevation 580 ft. The curve shown in Figure 7 was produced by plotting column (12) vs.column (11) in Table 4.

Figure 7. Dam top elevation during the failure of the embankment

The only output parameter from DBREACH used in SOCH is the time of complete failure(Figure 7). While the headwater elevation (Figure 5) and discharge through the failedsection (Figure 6) are computed and shown as outputs from DBREACH they are not used inthe SOCH simulations.

5.3 Use of DBREACH output in SOCHThe time of failure is determined by DBREACH. At the determined time of failure the SOCHrouting would shift to an after failure dam rating curve or a total failure of the embankmentwould be postulated to occur instantaneously. The after dam failure rating curve iscalculated independently of DBREACH.

In the example described in the previous section the time of failure is 17.78 hours. At thistime the embankment subject to failure is postulated to fail instantaneously. The SOCHrouting would shift to an after failure rating curve or total failure at 17.78 hours.
