IntroductionThe Water Surface Profiling product allows you to develop stream alignments and cross-section data that then can be transferred to HEC-RAS. HEC-RAS is a Water Surface Profiling program developed by the U.S. Army Corps of Engineers Hydraulic Engineering Center that replaces HEC-2. This program allows you to perform one-dimensional steady flow calculations. After the river or stream is modeled in HEC-RAS, Water Surface Profiling imports the resultant data and create a profile of the river or stream. You can also create a floodplain delineation of the stream or river as well.

Eagle Point’s Water Surface Profiling product does not perform hydraulic computations by itself. You must have HEC-RAS installed. See Installing HEC-RAS (below) for information on how to install HEC-RAS.

Water Surface Profiling Features! Define Stream alignments (numerically or graphically)

! Define Cross-Section alignments (numerically or graphically)

! Input cross-section data by hand

! Extract original ground cross-section data from surface models or drawing elements

! Query and View original ground cross-sections

! Import/Export cross-section data in over 100 predefined formats with the ability to customize your own formats

! Export stream alignments and original ground cross-section data into HEC-RAS

Import results from HEC-RAS to:

! Draw multiple Water Surface Profiles from different flow scenarios in HEC-RAS

! Display water extents of each flow profile (floodplains)

! Display the Cross-Section boundary to indicate where contraction occurs due to hydraulic structures and bridges input through HEC-RAS

Installing HEC-RASThe installation of HEC-RAS contained on your Eagle Point CD is the full installation and provides all of the program files, help files, user and reference manuals, and example files that normally accompany the HEC-RAS program. The current version shipped and supported with Eagle Point is HEC-RAS 2.2.

" If you already have HEC-RAS version 2.2 installed on your machine you do not have to
install the version included on the Eagle Point CD.

The HECRAS folder on the root of the CD contains the setup routine and sub folders that are needed to complete the installation of the HEC-RAS program. Three of the folders contain the written documentation for HEC-RAS. The manuals are stored in PDF format and require the Adobe Acrobat Reader to view. If you do not have a PDF viewer installed on your machine, you may install the reader from the Eagle Point CD Startup Kiosk.

The \HECRAS\USERMAN folder contains the HEC-RAS User's Manual, which explains how to use HEC-RAS. The user interface is described along with the underlying theory behind the program. A sample project is outlined, which works like a tutorial.

The \HECRAS\APPGUIDE folder contains the Applications Guide. This manual contains the text for the example projects that are stored in the HECRAS Data folder under the main RAS directory. Each of the examples is fully explained including the rationale for choosing certain options.

The \HECRAS\HYDREF folder contains the Hydraulic Reference Manual. This manual presents the theory and data requirements for hydraulic calculations in the HEC-RAS program. There is further discussion on modeling bridges, culverts, multiple openings, weirs, and spillways. Some of the optional capabilities are discussed as well, including bridge scour analysis and ice flow analysis.

HEC-RAS OverviewThe Army Corps of Engineers’ replacement for HEC-2 is HEC-RAS. HEC-RAS is an acronym for the Hydrologic Engineering Center’s River Analysis System. This software allows you to perform one-dimensional steady flow analysis. In the future, Unsteady Flow and Sediment Transport will also be supported. One of the major advantages to using HEC-RAS is the new Windows interface. The entire program is dialog box-driven and gives you the ability to copy and paste data when needed. The program supports tabular entry of data and full 3-dimensional graphics. Below are examples of the interface.

The figure below shows the main menu in HEC-RAS. On this menu you can perform file management within HEC-RAS. You can have a project that may have many different Plans. A Plan has an associated Geometry and Flow data associated with it.

The HEC-RAS View Cross-Section dialog box (Figure 1-8 on page 8) shows an example of the cross-section view. HEC-RAS allows you to view your cross-sectional data

graphically as well as modify it graphically. The Geometry Editor in HEC-RAS allows you to modify the cross-sectional data in a table.

Figure 1-9 (below) shows an example of the 3-Dimensional perspective plot. You can view the river system in a perspective view. HEC-RAS allows you to manipulate the scale of the view and rotation angles in the horizontal and vertical plan so you can change your view perspective.

Hydraulic Analysis ComponentsThere are several Hydraulic Analysis Components, which include Steady Flow Water Surface Profiles, Unsteady Flow Simulation, and Sediment Transport/Movable Boundary Computations.

Steady Flow Water Surface ProfilesThis component of the modeling system is intended for calculating water surface profiles for steady gradually varied flow. The system can handle a full network of channels, a dendritic system, or a single river reach. The steady flow component is capable of modeling subcritical, supercritical, and mixed flow regime water surface profiles.

The basic computational procedure is based on the solution of the one-dimensional energy equation. Energy losses are evaluated by friction (Manning’s equation) and contraction/expansion (coefficient multiplied by the change in velocity head). The momentum equation is utilized in situations where the water surface profile is rapidly varied. These situations include mixed flow regime calculations (i.e., hydraulic jumps), hydraulics of bridges, and evaluating profiles at river confluences (stream junctions).

The effects of various obstructions such as bridges, culverts, weirs, and structures in the floodplain may be considered in the computations. The steady flow system is designed for application in floodplain management and flood insurance studies to evaluate flood way encroachments. Also, capabilities are available for assessing the change in water surface profiles due to channel improvements and levees.

Special features of the steady flow component include: multiple plan analyses; multiple profile computations; and multiple bridge and/or culvert opening analysis.

Unsteady Flow SimulationThis option is not available yet. This component of the HEC-RAS modeling system is capable of simulating one-dimensional unsteady flow through a full network of open channels. The unsteady flow equation solver is adapted from Dr. Robert L. Barkau’s UNET model (Barkau, 1992 and HEC, 1993). This unsteady flow component was developed primarily for subcritical flow regime calculations.

The hydraulic calculations for cross-sections, bridges, culverts, and other hydraulic structures that were developed for the steady flow component are incorporated into the unsteady flow module. Additionally, the unsteady flow component has the ability to model storage areas, navigation dams, tunnels, pumping stations, and levee failures.

Sediment Transport/Movable Boundary ComputationsThis option is not available yet. This component of the modeling system is intended for the simulation of one-dimensional sediment transport/movable boundary calculations


resulting from scour and deposition over moderate time periods (typically years, although applications to single flood events are possible).

The sediment transport potential is computed by grain size fraction, thereby allowing the simulation of hydraulic sorting and armoring. Major features include the ability to model a full network of streams, channel dredging, various levee and encroachment alternatives, and the use of several different equations for the computation of sediment transport.

The model is designed to simulate long-term trends of scour and deposition in a stream channel that might result from modifying the frequency and duration of the water discharge and stage, or modifying the channel geometry. This system can be used to evaluate deposition in reservoirs, design channel contractions required to maintain navigation depths, predict the influence of dredging on the rate of deposition, estimate maximum possible scour during large flood events, and evaluate sedimentation in fixed channels.

For more information on HEC-RAS and its modeling methods, refer to the Hydraulic Reference Manual and the Applications Guide electronic documentation on the Eagle Point CD.

Previous Users of Eagle Point’s Water Surface Profiling Module

This version of Water Surface Profiling represents a major change from what Eagle Point has done in the past with respect to Water Surface Profiling. No longer is Eagle Point performing the hydraulic computations of the water surface profile. The program now allows you to create stream alignments, cross-section alignments and extract them, transfer the data to HEC-RAS, read the water surface profile data from HEC-RAS and create water surface profiles in CAD. All of the computations for the hydraulics are done by HEC-RAS.

Because of the reliance of HEC-RAS for the hydraulic calculations, Eagle Point no longer directly interacts with HEC-2. You are able to translate the cross-section data to HEC-2, however. The HEC-2 program is included in the Eagle Point Program directory so you can still run it manually. Keep in mind that HEC-2 is superseded by HEC-RAS and that the U.S. Army Corps of Engineers highly recommends using HEC-RAS instead of HEC-2 for any new projects.

Converting Old ProjectsThe Water Surface Profiling projects in EP 7.0s, EP 13, EP14, and EP99/2000 can be converted to run in the new EP 2000 version of Water Surface Profiling. An important note to be aware of is that only the alignment and cross-section data is converted. In EP

oncepts
7.0s, EP 13, EP14, and EP 99/2000, the cross-section data was oriented left-to-right as if you were looking upstream. This is not the normal convention for HEC-RAS. In EP 2000 Water Surface Profiling, the cross-sections are oriented left-to-right as you are looking downstream.
Because of the new interaction with HEC-RAS, Water Surface Profiling in EP 2000 does not have a different hydraulic calculation engine as in previous releases. All of the calculations are performed in HEC-RAS. If you have existing water surface profiles created, Eagle Point updates the profile drawings so that the profile data from HEC-RAS can be drawn in them. The structure data (culverts, bridges, and weirs) are not written to the profile. The water surface profile, channel invert, and the overbank profiles are written to the drawing/design file.

Conversion of previous projects is automatic when you are using the Convert Previous Projects command. For EP 13, 14, and EP 99/2000 Water Surface Profiling versions, all of the sub-projects are converted. The EP 7.0 Water Surface Profiling projects did not have sub-projects like the later versions did. In that case, you had one stream/reach per project. The 7.0 projects are converted when the sub-project is opened. You need to make sure the drawing/design file name is the same as the project name was in EP 7.0 in order for the data to be converted. Only the cross-sections are converted, since there were no alignments in EP 7.0. See Convert Previous Projects in the Getting Started manual for more information.

C h a p t e r 1 : C o n c e p t s 1 1

Typical Project FlowBecause the computational portion of the program is performed in HEC-RAS, there is a need to transfer between Water Surface Profiling and HEC-RAS. The flow chart below outlines the typical project flow in Eagle Point as you work on a sub-project.

Water Surface Profiling works with the following assumptions.

! One sub-project can only contain one stream centerline (reach).

! Stream Stationing runs upstream with the Beginning of Project Station the most downstream point.

! Cross-Sections are viewed left-to-right as you look downstream.

! Cross-Section alignments must touch or cross your stream centerline.

Chapter 1: C

oncepts
All of the alignment data can be entered either graphically or by entering the data through a dialog box interface. Use the Convert Objects to Stream Alignment command or enter the numeric data using the Edit Alignment Data command. Cross-section alignments can be defined graphically or numerically as well.
The cross-sections can be extracted from a surface model (DTM) or directly entered into the dialog boxes.

After the data is entered for the alignment and cross-sections, the data is transferred to HEC-RAS using the Export to HEC-RAS command. Once the data file is created, you import the HEC-RAS data into HEC-RAS using the Import Geometry Data command.

With the data imported into HEC-RAS, you then enter additional hydraulic information and perform the hydraulic computations in HEC-RAS. If you want to generate water surface profiles in CAD or generate floodplain maps, you can then use the Export GIS Data command in HEC-RAS.

At this point you import the GIS data file into Water Surface Profiling using the Import HEC-RAS data command. Once the information is imported, you can run the Water Surface Profiles or Delineate Floodplain command in the Output menu.

Refer to Export to HEC-RAS on page 84 and Import from HEC-RAS on page 89 for more information on transferring data to and from HEC-RAS.

Alignment ConceptsThis chapter focuses on stream alignments and cross-section alignments. An alignment is a string of lines and/or curves, defining in the plan view the location of a base line or of flow lines.

Stream Alignment DefinitionsA stream alignment defines the location of the stream centerline or overbanks in plan view. A stream alignment is made up of a string of lines and optionally, curves connecting control points. The different kinds of stream alignments are:

! Stream Centerline: A baseline along the stream from which the cross-section alignments are defined.

! Left and Right Overbank Alignments: These alignments define the banks of the stream channel.

Cross-Section Alignment DefinitionsA cross-section alignment defines the baseline of a cross-section; it is generally perpendicular to the stream flow direction. There are three kinds of cross-section alignments, as shown below.

Normal Cross-section: These alignments are straight lines perpendicular to the stream centerline at the stream station specified by that cross-section.

Skewed Cross-section: Skewed cross-sections are similar to the Normal type, except that they are at a skew angle to the stream centerline.

Fixed Cross-section: Fixed cross-sections are defined by lines connecting cross-sectional Points of Intersection (PI). These cross-section alignments are not necessarily normal to the stream centerline, since they can be defined by many cross-sectional PI’s.

Figure 2-1 Cross-Section Alignment Types

Stream AlignmentsThe plan view drawing contains all of the alignments for streams in the current project. Each stream alignment represents a separate sub-project. When viewing and editing alignment data in the Edit Alignment Data dialog box (Figure 2-4 on page 19), only the current sub-project data is used. To edit the alignment graphically and transfer the graphic data to numeric data in the dialog boxes, be sure the stream alignment for the current sub-project is being edited. Water Surface Profiling keeps track of any graphic changes and updates the alignment database accordingly. Conversely, any changes made to the alignment in the dialog boxes automatically update the graphic as well.

Water Surface Profiling represents stream alignments as 2-D polylines/line strings with no elevation consisting of lines and arcs. Tangent lines are lines, and circular curves are arcs. These graphic elements contain attribute data that identifies the sub-project the alignment belongs to, as well as stationing and the direction the alignment runs. The most downstream end of the stream is considered the BOP location for the alignment.

Overbank AlignmentsThe Overbank Alignments define the banks of the stream channel. These alignments are optional and do not need to be defined. You could define the overbanks separately in HEC-RAS if you desire. The Overbank Alignments are similar to the Stream Alignments in that they are represented as 2-D polylines/linestrings with no elevation. The alignments can be constructed with lines and arcs. You can graphically enter the alignments in CAD and convert the object to an alignment or directly enter the alignment data in the dialog boxes.

When the overbank alignments are defined, Water Surface Profiling interpolates the cross-section stations for the overbanks. The Left Overbank is the overbank on the left side of the stream alignment as you are looking downstream. Conversely, the Right Overbank is the overbank on the right side of the stream alignment as you are looking downstream. See the figure below.

Figure 2-2 Overbank Alignments Defined


Some obvious limitations are as follows: the overbank alignments cannot cross each other, each overbank alignment should extend the full length of the stream alignment and the overbank alignments must be continuous with no gaps.

Cross-sectional AlignmentThere are two types of cross-sectional alignments in Water Surface Profiling. The first is a straight line cross-section alignment defined relative to the stream centerline. The second is a fixed cross-section alignment, which is a series of lines connecting cross-sectional PI’s. The cross-section alignment of the first kind (relative to the stream centerline) can either be normal to the centerline or at a skew angle. Use this type of cross-section alignment for streams that are mostly uniform.

When using the second kind of cross-section you must enter the cross-sectional PI’s defining the cross-section alignment as well as the stream station for that cross-section. The PI’s are connected using straight lines to form the cross-sectional alignment. Use this type of cross-sectional alignment for wide waterways that are not uniform in order to keep the cross-section alignment normal to the flow lines of the waterway. The stream station is used as a unique number identifying that cross-section, and to sort this cross-section with the others, by ascending order. When working with cross-section alignments, there is a station along the cross-section alignment that corresponds to the point the cross-section alignment crosses the stream alignment. The station is known as the Station at Center. Figure 2-3 (below) illustrates the station at center on a cross-section alignment.

The stationing on the cross-section alignment runs from left to right as you are looking downstream. This is consistent with the cross-section stationing in HEC-2 and HEC-RAS.

" The first PI entered in a project must be entered by coordinates (or Node ID) only. Until this is done, the angle option area is unavailable. If coordinates are not important to the sub-project, just enter zeroes for the BOP coordinates. When entering coordinates they may be state-plane, local or assumed.

By changing the method drop list, PIs may be entered by Node ID or coordinates or by angle and distance. When the method is set to coordinates the Northing and Easting values may be typed or picked from the CAD graphic. Use the pick in CAD (PIC) button to graphically pick the location (coordinates) of the PI. If an Eagle Point Node exists at the location of a desired PI type, type the Node ID or select it graphically using the PIC button. Remember that when using the PIC button, what you are selecting in CAD depends on which edit fields have focus (i.e., to graphically select a Node, put focus into the Node ID edit field and click on the PIC button).

When the method is set to one of the angle or direction options, the dialog box looks like Figure 2-8 on page 23. Enter the angle/direction and distance numerically or use the PIC button to select an object in the CAD graphic to retrieve the direction or distance along that object.

" Water Surface Profiling accepts angles in DDD, MMSS, or DDD.DDD format, depending on the project format specified. For example, to enter 18 degrees, 43 minutes, 30 seconds in DDD.MMSS, type 18.4330. To enter it in DDD.DDD, type 18.725.

A toggle button allows the coordinates of any PI to be fixed. A fixed coordinate is indicated with an F in the status column on the Edit Alignment Data dialog box (Figure 2-4 on page 19). When PIs are modified, added or deleted, Water Surface Profiling holds the coordinates of a fixed PI and recalculates the angle and distance to it.

Manage Alignments

KEY-IN COMMAND: wpalman

Any fixed cross-section alignments that are created, as well as the default alignments (Stream Centerline, Left Overbank, and Right Overbank) display in the Manage Alignments dialog box (Figure 2-15 on page 31), also referred to as the Alignment Manager. The Alignment Manager displays when Manage is selected from the Alignments pull-down menu. This allows cross-section alignments to be added, copied, modified, or deleted from the list, and allows changes to be made to the settings for an alignment. The listing also displays the Stream Station at which a cross-section alignment is positioned. The cross-section alignments are sorted in the list in ascending stationing.

Fixed cross-sections are cross-sections that are not straight lines but are lines with kinks or bends in them. The reason for the kinks is to maintain the cross-section perpendicular to the stream flow. The Fixed Cross-Section example (below) illustrates this. Add these cross-section alignments by using the New Cross-section Alignment command, which sorts the cross-sections by station value in the Alignment Manager. Then use the tools mentioned before to create the alignment geometry (either associating an alignment that is already defined, using the Convert Objects to Alignment command and/or using the Edit Alignment Data commands). If the object that is converted to be a cross-section alignment is not at the station originally specified, Water Surface Profiling calculates the correct station.

The Stream Centerline alignment is used as the baseline, or the alignment on which cross-section stations are based. If an alignment already exists within the project that should be used in this fashion, highlight the Stream Centerline alignment in the Manage Alignments dialog box (Figure 2-15 on page 31) and click on the Associate Alignment button. This displays the Associate Alignment dialog box (Figure 2-17 on page 34), which

lists all of the project alignments. From this listing you can select the alignment geometry that you want to use as the sub-project’s Stream Centerline, either by copying the alignment to another name or by directly editing the previously defined alignment.
See Associate Alignment on page 33.

The stationing on the cross-section alignment runs from left to right as you are looking downstream. This is consistent with the cross-section stationing in HEC-2 and HEC-RAS.

Highlight the alignment in the Alignment Manager listing that you want to associate a defined alignment to and select the Associate Alignment command. After selecting the alignment in the Associate Alignments dialog box click on OK. The alignment name in Water Surface Profiling is changed to match the name in the Alignment Database and the Drawing Path column now indicates the alignment is defined in some CAD graphic. If you associate the wrong alignment, use the Associate Alignments command again, highlighting the proper alignment on the Alignment Manager and in the Associate Alignment dialog box (Figure 2-17 on page 34).

Remove Association

This command removes the association of the data in the Alignment Database with the alignment highlighted. If you remove the association with one of the default alignments (numbers 1, 2, or 3) the alignment name and data is kept in the Alignment Database and the sub-project number is set to 0. The alignment name in the Manage Alignments dialog box is returned to the default (Stream Centerline, Left Overbank or Right Overbank) and is marked as “Not Defined.” The data can no longer be edited within Water Surface Profiling. If the Remove Association is performed on an alignment other than the defaults, the same things happen except the alignment name within the Manage Alignments dialog box is set to “Undefined Alignment #” where # is the number of the alignment in the list.

Any modifications made within Water Surface Profiling are written to the copied alignment.

If you choose to associate the selected alignment, Water Surface Profiling accesses the alignment directly from the database. When a change is made to the alignment in Water Surface Profiling, that change is immediately written to the project Alignment Database.

If you wish to completely remove an alignment from the project use the Delete Alignments command in the Manage Alignments dialog box. This not only removes it from the list but it also deletes all PI data from the Alignment Database and alignment CAD graphic.

As changes are made to the alignment data, the changes are automatically saved to the Alignment Database and the alignment graphic is updated immediately if you are editing it in the alignment’s drawing/design file. When you close the Edit Alignment Data dialog box and you are not in the proper drawing/design file and if no other user is accessing that drawing/design file, you are prompted to save changes in your current CAD graphic. Water Surface Profiling opens the alignment drawing, updates the graphic and redisplays your previous CAD graphic. If another user is currently accessing the alignment drawing/design file you are prompted to send a message to the user informing them why a change was made. When that user runs another Eagle Point command, a dialog box displays with a warning about who changed what alignment and that Eagle Point is going to update the graphic alignment. This message also informs the user to save changes to that CAD graphic so that the data and graphic remain in sync. For more information, refer to Manage Alignments on page 30.

KEY-IN COMMAND: wputil

The Manage Utilities command provides a means to define three-dimensional geometry as a utility. When you define a new utility, you enter a name and other information that is used to represent what the utility looks like when it is viewed in a cross-section or profile view. The Annotation Settings button on the Manage Utilities dialog box (Figure 2-20 on page 39) allows you to set how the utility is annotated. You then use the Convert Objects to Utility button found in the Manage Utilities dialog box to define the horizontal and vertical geometry of the utility.

Utilities are stored on a per-project basis. When utilities are defined, that definition is available for all aspects of the project. The Annotation Settings for each utility are used to determine how the utility is displayed in various locations throughout the Eagle Point Software. The utilities that meet the Annotation Settings are displayed.

Storm and Sanitary Sewer networks that have been created are automatically added as utilities. The diameter is displayed as Variable since you can have different pipe sizes and shapes for the sewer networks. When a hydraulic profile is created for a sewer reach using a RoadCalc centerline as a reference alignment, the network can be displayed in the RoadCalc profile drawing.

Below is a list of the products and commands that display the utilities:

The Order column determines the sequence in which the annotation displays and the Annotation Placement setting controls whether the text is placed above, below, to the left, or to the right of the utility. The lower portion of the dialog box contains settings for how the utilities display in cross-section and profile views.

The Cross-Section Display Distance is used to determine which utilities within the specified distance should be viewed when looking at an individual cross-section. The distance is used to calculate a boundary around a cross-section. If the utility crosses into that boundary, it is displayed. How the utility is shown in the Cross-Section view is determined by the angle from parallel tolerance. If the utility is within the specified angle tolerance from the cross-section line, it is displayed in profile form. If it is outside the angle tolerance, every vertex of the utility (including if it intersects the cross-section line) is shown as a utility cross-section. Figure 2-23 on page 43 shows the result of using a cross-section display distance of 50 feet and an angle from parallel tolerance of 45 degrees.

The Profile Display Settings are very similar to the Cross-Section Display settings except they control how the utility should be drawn when looking at a profile view. The Profile Display distance is used to offset the centerline alignment both left and right by the specified amount. Then, a check is made to see if the utility falls within the bounding corridor. If it does, the utility is going to be shown in the profile view. The Profile Angle from parallel tolerance is then used to determine whether the utility is displayed as a profile or cross-section. If the utility is within the angle tolerance measured from the centerline, it is displayed in profile form. If it is outside the tolerance, every vertex of the utility (including if it intersects the centerline alignment) is shown as a utility cross-section. Figure 2-24 on

Diameter Specify the diameter of the utility in inches (or millimeters). This value is always used when displaying the utility profile and may be used to display the utility in a cross-section view. If the utility does not have a diameter, (i.e. an underground cable) specify the diameter to be very small.

Annotation The toggles for each item control whether or not that item should be annotated when the utility is viewed. The label lets you specify what text appears with the utility and the order controls the sequence in which the labels are placed. Items that can be annotated include the name, station, offset, elevation, diameter, or a user-defined note.

Annotation Placement

This option controls where the Annotation items display when the utility is viewed. Choose to place the annotation above, below, to the left, or to the right of the utility.

Cross-Section Display Distance

This distance defines the boundary to search for the utility to see if it should be displayed in a cross-section. The distance is used to offset the cross-section line and form a boundary around the cross-section. If the utility falls inside the boundary, it is seen in the cross-section view.

Cross-Section Angle from parallel tolerance

This angle tolerance (measured in degrees) is used to determine whether a utility is seen as a profile in a cross-section view. If the closest utility leg to the cross-section is within the tolerance, it is displayed in profile form.

Profile Display Distance

This distance defines the boundary to search for the utility to see if it should be displayed in a profile view. The distance is used to offset the centerline alignment and form a boundary around it. If the utility falls inside the boundary, it is seen in the profile view.

Cross-Sections ConceptsThe commands found in the Cross-Sections menu allow you to input, edit, and translate the cross-sectional data. Enter and edit the data directly with the Edit Cross-Sections routine, or bring the cross-section data into Water Surface Profiling from outside sources using the Extract Cross-Sections or the Import Cross-Sections routines. The data can be translated in the WSPRO or HEC-2 formats among others.

$ Cross-sections must be placed at the PI locations of the stream alignment. If the cross-sections are omitted from the stream alignment PI’s, the reach lengths may not be calculated correctly when the data is exported to HEC-RAS.

Cross-Section TypesThere are three cross-section types that are supported in Water Surface Profiling. These three types are Normal, Skewed, and Fixed. Normal cross-sections are cross-sections perpendicular to the stream alignment. Fixed cross-sections are briefly described in Chapter 2 (Alignments on page 15). Fixed cross-sections follow the cross-section alignments. Skewed cross-sections are described in Skewed Cross-Sections (below).

Skewed Cross-SectionsSkewed cross-sections are available for cross-section locations that require an angle other than perpendicular to the stream alignment (0 degrees).

Determine the angle at which the cross-sections are skewed by one of five methods:

! Left-Hand Forward (LHF)

! Right-Hand Forward (RHF)

! Deflection Left (DL)

! Deflection Right (DR)

! Azimuth (AZ): Based upon 360 degrees

Selecting LHF allows angles to be entered from -90 degrees to 90 degrees to be read from the second and third quadrants. Selecting RHF allows angles to be entered -90 degrees to 90 degrees to be read from the first and fourth quadrants. Figure 3-1 on page 49 illustrates the LHF and RHF methods and quadrants. Selecting Deflection Left allows angles to be entered from 0 degrees to 180 degrees to be read from the second and third quadrants. Selecting Deflection Right allows angles to be entered from 0 degrees to 180 degrees to be read from the first and fourth quadrants. If none of these four are specified,


Chapter 3: C

ross-Sections

use the Azimuth method and enter an angle between 0 degrees and 360 degrees as shown in Figure 3-3 (below).

The Right-Hand Forward convention can be explained by imagining that the gray line (the light solid line) in Figure 3-4 on page 50 represents a person’s arms extending out from their sides, 90 degrees, looking downstream along the alignment. The black line (the heavy solid line) in each figure represents the person’s arms if they rotate their body (keeping their arms straight), to the angle specified. In the first figure, the person’s right

Figure 3-3 360 Degree Method For Measuring Skew Angle


arm moved forward 20 degrees of rotation. In the second figure, the left arm moved forward 20 degrees (LHF) which causes the right arm to move backwards 20 degrees, or -20 degrees forward (RHF).

Cross-Section StationingUnlike roadway cross-sections, the cross-sections in Water Surface Profiling do not use Offsets and Elevations to describe the cross-section. Water Surface Profiling uses stations and elevations. You define a station at center value in Cross-Section Settings that represents the station on the cross-section where it crosses the stream centerline. Another important difference is that the stationing along the cross-section runs left to right as you look downstream, not in the direction of the stream stationing. This applies to all of the cross-section types. See Figure 3-5 (below).

Figure 3-4 Explanation Of RHF Convention

Figure 3-5 Cross-Section Stationing Example


Chapter 3: C

ross-Sections

Cross-Section SettingsSpecify the horizontal and vertical tolerances for the cross-section by selecting Cross-Sections ! Settings. The values for the horizontal and vertical tolerances can be specified to selectively remove points from the information being used to generate the cross-sections. This is useful when generating cross-sections from dense surface models to reduce the number of points used for each section by removing redundant points.

Consider an example (below) of the vertical tolerance equaling VT and the horizontal tolerance equaling HT. The program would work as follows:

The vertical distance for point #2 would be checked (represented by line V1). It is less than the vertical tolerance (VT) so it fails. The program now checks the horizontal distance (line H1). Line H fails the horizontal tolerance (HT) also so the point is not used. Now the program checks the next point, point #3. The vertical distance for point #3 (line V2) is greater than the specified vertical tolerance (VT) so the point is used. The horizontal tolerance is not checked because the point passed the vertical tolerance. A line would now be connected between points 1 and 3 (shown as a dashed line). Point #4 is next and the vertical distance (line V3) is less than the specified tolerance. The point fails so the horizontal distance is checked and is greater than the horizontal tolerance. The point is kept and a line from point #3 to point #4 is generated.

Import/Export DataThis routine provides an interface between Water Surface Profiling and external sources of cross-section data. The translator reads cross-section data from an ASCII file and translates it into Water Surface Profiling’s binary format. The ASCII file may be in one of

Figure 3-6 Horizontal And Vertical Curve Tolerance


Water Surface Profiling’s pre-defined formats, or define a custom format for the data. Water Surface Profiling can also translate from Water Surface Profiling binary to ASCII formats. Keep in mind that you can export HEC-2 and WSPRO formats as well.

The data in the ASCII file can be in coordinate or station-offset format, but the data must be taken along cross-section lines. Also, if the ASCII file contains data in station-offset format, the stations must be listed in order along the sub-project. If the data is in coordinate format, the stations may be out of order, but the horizontal alignment must be entered before translating.

Before translating, remove any extraneous lines from the ASCII file: title blocks, comments (unless they are part of a descriptor field), and any blank lines, whether they are at the beginning, middle or end of the file.

When importing a coordinate ASCII file, you can toggle on the station tolerance option found in the transfer settings. Specify the station tolerance and station interval. This allows you to force the points in the ASCII file to fall on exact station values within the tolerance specified. When the option is toggled on, the station values along the centerline alignment are calculated for the points. The calculated stations in the file are compared to the interval stations along the centerline alignment. The difference between their actual station value and the stations at interval will then be compared to the station tolerance. If the point is inside the tolerance the shot is assigned to the interval station. If a shot is outside the tolerance it is added to a running list and displayed at the end of the command. When all other shots are given an interval station, the Assign Points to Station dialog box (Figure 3-23 on page 75) is displayed. This allows you to decide what to do with all shots outside of the station tolerance. Points can be discarded or assigned to existing or new station values. To assign a point to a station value, highlighting the rows that belong to the same station and then use the Assign Station button to enter the station at which the shots belong. As changes are made (i.e. a group of shots are assigned a station) the list of points in the Assign Points to Station dialog box are updated by removing the shots that were in the highlighted group. If points are not assigned to a station value and the Assign Points to Station dialog box is closed, the shots are discarded.

For example, in the Transfer Settings – Import Tab, set the station tolerance to 0.5 and the station interval to be 10. If the data importing calculated a station of 99+99.89 from the coordinates because of precision, Water Surface Profiling would automatically adjust that station to be 100+00 since the station tolerance of 0.11 is less than 0.5.

If the ASCII file contains sideshots that are not to be translated, group these shots at the end of each cross-section and put an XX in the descriptor field of the last point that is translated for that cross-section. Water Surface Profiling ignores all points including and after the one marked with the XX until it reaches the points on the next cross-section.

If there is already cross-section data for the surface you are translating, Water Surface Profiling must know what to do if it encounters a station in the ASCII file that matches a station already in the sub-project. It can either overwrite the old data at that station or add the new shots to the shots already there (append). If a window displays asking if the old data is to be overwritten, indicate the action to be taken.

Edit Cross-Section Data

KEY-IN COMMAND: wpxsdata

ICON:

When the Edit Data command is selected from Water Surface Profiling’s Cross-Sections menu, Water Surface Profiling opens the Edit Cross-Section Data dialog box (Figure 3-7 on page 54). The upper list box contains a listing of all the cross-sections along the stream in the sub-project. The lower list box shows stations and elevations along the highlighted cross-section. If cross-section data has not been entered, the dialog box shows no cross-sections.

If cross-section alignments have been defined, the cross-section stations display in the Stream Station listing with a status of F for fixed. These cross-sections cannot be deleted from the listing. They must be deleted from the Alignment Manager in the Alignment menu.

If the cross-section has been interpolated from existing cross-section geometry, an I displays in the Stream Station listing.

Unless the Import or Extract Cross-Sections commands have been used to bring data into Water Surface Profiling, the Edit command is used to enter and edit data for the ground surface.

Added cross-sections are automatically sorted by their station values. Multiple stations may be added at one time by using the Build List option.

" To enter cross-section data graphically, the cross-sections CAD graphic must be loaded. If not, use the View Cross-Section Graphics command found in the Cross-Sections menu. A vertical line representing the centerline and a station label indicating the station being viewed display. From this point, the cross-section can be drawn. Use lines or polylines/line strings to represent each surface.

" Coordinates: The X-coordinate in the cross-section CAD graphic corresponds to the stream centerline offset. The Y-coordinate is the elevation if the vertical stretch factor is set to one. Otherwise, the Y-coordinate is the elevation multiplied by the vertical stretch factor. See Cross-Section Settings on page 51 for details on the vertical stretch factor.

Unlike most other routines in Water Surface Profiling, the cross-section routine does not save the CAD graphic it uses. The CAD graphic here is merely a graphic environment for the cross-section work. Once editing of a section is complete, Water Surface Profiling saves the data in its own files and discards the CAD graphic. Annotation or other extraneous information is lost.

(Figure 3-16 on page 66) displays. If the sub-project has no cross-sections yet, the program opens the Build Station List dialog box (Figure 3-11 on page 58), and allows you to set the desired station range and station interval.

This routine allows cross-sections to be created from a surface model created previously with the Eagle Point Surface Modeling product. The program routes the stream centerline alignment through the model, and at requested stations, slices the model with vertical planes perpendicular to the alignment for normal cross-sections. Wherever a plane intersects a surface model triangle line, a cross-section shot is generated. In the case of fixed cross-sections, a cross-section shot is generated everywhere the cross-section line crosses a surface model triangle and at the vertex points of the cross-section alignment.

Once the stations are marked appropriately, click on OK to initiate the cross-section generation process.

After processing, Water Surface Profiling may display an error dialog box. This indicates stations where it was not able to generate data all the way out to the corridor edges, and stations where it was not able to find any data at all.

Import Cross-Sections

KEY-IN COMMAND: wpxsimp

The Import command provides an interface between Water Surface Profiling and external sources of cross-section data. The translator reads cross-section information from an ASCII file. The ASCII file may be in one of Water Surface Profiling’s pre-defined formats, or you may define a custom format for the data.

See Import/Export Data on page 51.

" Water Surface Profiling uses the stream centerline alignment to translate coordinate format ASCII files. Enter an alignment before translating a coordinate format ASCII file. This allows the stations to be out of order and a shot is no longer needed on the centerline.

" Since translation alters the binary cross-section files, it is a good idea to make copies of all of the sub-project’s data files before translating additional data into Water Surface Profiling.

Transfer ConceptsWater Surface Profiling allows you to transfer data to and from HEC-RAS. The Export to HEC-RAS command allows you to export the stream alignment and cross-sections to a GIS format data file that can be imported into HEC-RAS. Once the data is imported into HEC-RAS, you can then manipulate the data and add bridge, culvert, and levee data to model the stream correctly. While you have the data in HEC-RAS, you are also able to take advantage of HEC-RAS' 3-D viewing capabilities. HEC-RAS also provides for extensive report formats and plotting abilities. All of the hydraulic computations are performed in HEC-RAS as well.

If you would like to create a profile plot of the water surface in CAD or delineate a floodplain in CAD, Water Surface Profiling also gives you that capability with the Import from HEC-RAS command. The Import from HEC-RAS command allows you to import the water surface information back into Eagle Point so it can be plotted in CAD. See Water Surface Profiles on page 94 and Delineate Floodplain on page 99 for more detailed information.

Step-by-step instructions (Export to HEC-RAS Procedure on page 86 and Import from HEC-RAS Procedure on page 90) are provided in this chapter. For more information on the files created/read for the import/export process, see Appendix B in the HEC-RAS Users Manual.
