G-1. Introduction

A regional groundwater flow model was developed and applied as part of the Arkell Spring Grounds

investigation to simulate existing groundwater flow conditions in the Arkell Spring Grounds area, to

predict the effects of increased groundwater taking on groundwater levels and discharge to the Eramosa

River, and to estimate the surface projection of the capture zones for the Arkell Spring Grounds takings.

The regional model covers an extensive area that includes the City of Guelph, the Township of

Guelph/Eramosa, portions of the Townships of Puslinch, Woolwich and Centre Wellington and a portion

of the Town of Erin that includes Blue Springs Creek. Arkell Spring Grounds is located in the southeast

portion of the regional model, as shown in Figure G-1.

The City of Guelph (City) conducted a comprehensive investigation of its water works system in 1990

(Braun Consulting Engineers and Jagger Hims Limited [JHL], 1991) [referred to subsequently as

BCE (1991)]. The study led to four aquifer performance evaluation studies, one for each of the city

quadrants (JHL; 1993, 1995, 1997, and 1998). Preliminary single-layer models were developed for the

northeast and northwest quadrants that investigated flow within the Amabel aquifer.

The data gathered in the quadrant studies, along with additional geophysical data, provided information

needed for a more detailed, three-dimensional model of the entire area encompassing the City. A three-

dimensional, numerical, regional groundwater flow model employing the United States Geological

Survey (USGS) MODFLOW computer code (McDonald and Harbaugh, 1988) was initially developed by

Gartner Lee Limited (Gartner Lee) in 1998 for City use. The development of this preliminary model,

involved the formulation of a conceptual model of the geologic and hydrogeologic setting of the study

area, followed by the design of the numerical model, preparation of data input, model calibration, and

model application. The model was refined in 1999 to incorporate additional local-scale information for

the Torrance Creek sub-watershed. Improvements included the use of a finer model mesh in the Torrance

Creek area, incorporation of more data on local geology, and better representation of flow in the creek.

The model was subsequently expanded and updated in 2002/2003 for the Township of Guelph/Eramosa

Groundwater Study (Gartner Lee, 2003). The model was further expanded as part of the Arkell Spring

Grounds Investigation to encompass the northern half of the Mill Creek watershed in the Township of

Puslinch. The expansion of the model beyond the original boundaries, shown in Figure G-1, was needed

to assess whether pumping within the City of Guelph was inducing groundwater flow across surface

water basin boundaries.

The development of the conceptual and numerical models and the results of model calibration and

verification are the subject of this report. Results of applying the model to predict the potential impact of

increased water takings in the Arkell Spring Grounds are presented in Section 6 of the main report.

Appendix G: Groundwater Model Development

G-2. Conceptual Model

The first step in building a groundwater flow model is to develop a complete understanding of the aquifer

system. This understanding, often referred to as a conceptual model, encompasses the physical and

hydrogeologic setting of the study area and the factors that govern groundwater flow in the aquifer

system. The conceptual model addresses key technical issues including:

1. bedrock and overburden stratigraphy;

2. configuration and continuity of the major aquifer and aquitards;

3. physical conditions along the boundaries of the flow system;

4. initial conditions (i.e., historic and current groundwater levels);

5. initial estimates of aquifer and aquitard properties; and,

6. rates of recharge and groundwater discharge.

Bedrock and overburden stratigraphy and aquifer/aquitard geometry were determined based on data

collected in previous investigations, analysis of well logs, and interpolation of point data to create the

stratigraphic layers used in the numerical model. It was assumed that variation in the properties of

overburden soils is the most important control on the magnitude of groundwater recharge in the Guelph

area, while variation in the hydraulic properties of the bedrock units were the primary control on the flow

of groundwater. Aquifer properties that control groundwater flow include horizontal hydraulic

conductivity of the aquifers and vertical hydraulic conductivity of the aquitards. Groundwater discharges

from the bedrock aquifers through baseflow into streams and pumping at municipal and private permitted

wells.

Data on groundwater levels and regional flow patterns were used to define the extent of the area modelled

and to determine the boundary conditions specified on the external boundaries of the model. Initial

estimates of aquifer properties were assigned to zones within each layer in the numerical model. These

initial estimates were subsequently refined during the process of model calibration. Water budget

analyses were conducted to calculate initial estimates of the rates of natural recharge. Data on water use

and stream baseflow were compiled and analyzed to determine rates of groundwater discharge.

Brief discussions on the geologic and hydrogeologic setting of the area, based on the results of the earlier

work and conceptual model development, are provided in the following sections. A simplified

stratigraphic model of the units comprising the aquifer system is shown in Figure G-2.

G-2.1 Topography and Drainage

G-2.1.1 Land Surface Topography

Land surface elevations range from about 430 metres above sea level (mASL) in the northern portion of

the study area (north of Guelph Lake at the Guelph-Eramosa Township and Town of Erin boundary) to

about 300 mASL downstream of the confluence of the Speed and Eramosa rivers. A map showing

contours of equal land surface elevation is presented in Figure G-3. Topographic data, based on the

Digital Elevation Model (DEM) used in the Guelph-Eramosa Township Groundwater Study (Gartner Lee,

2003), were interpolated to the centre of each model cell in the grid used to represent the study area. The

DEM data were obtained from the Ministry of Natural Resources’ Natural Resources Values Information

System.

Information on land surface topography was used in the model to assign control elevations on the streams

that drain the study area. This information was also used during the process of model calibration, in

conjunction with well data, as a check on the predicted groundwater levels.

G-2.1.2 Surface Water Drainage

Figure G-3 also shows the larger rivers and numerous smaller streams that drain the study area. The

study area falls within the Speed River sub-watershed, and more locally the Eramosa River watershed.

The Eramosa River joins the Speed River within the City of Guelph. Guelph Lake was constructed on the

Speed River to provide flood control and low-flow augmentation. The Speed River joins the Grand River

at Cambridge. The two principal streams that drain the Eramosa River sub-watershed include the

Eramosa River and Blue Springs Creek. Further discussions on surface drainage in the study area can be

found in the quadrant reports (JHL, 1993, 1995, 1997, and 1998).

The major surface water features were incorporated as head-dependent sources/sinks in the model.

G-2.2 Geology

G-2.2.1 Surficial Geology

Surficial geology for Southern Ontario was mapped on a large scale by Chapman and Putnam (1984).

The study area was described and mapped by P.F. Karrow (1968, 1987). Much of the discussion below is

derived from these reports and from the City’s quadrant studies. Figure G-4 shows the surficial geology

based on a digital version of available mapping for the area compiled by the Ministry of Northern

Development and Mines. Surficial geology zone numbers were assigned to each cell in a rectangular grid

used to represent the study area. The surficial geology zones were subsequently used in the numerical

model to assign hydraulic conductivity and recharge rates to the overburden.

Appendix G: Groundwater Model Development

The western part of the study area is located on a drumlinized till plain that regionally slopes to the south

with a gradient of about 3.5 m/km (Chapman and Putnam, 1984). The drumlins are oriented to the west-

northwest, are broad and oval shaped, and are composed of the sandy silt Port Stanley Till. The till plain

is bordered to the east by the Paris and Galt Moraines. The till is underlain by dolostones of the Amabel

and Guelph Formations.

The surficial geology mapping was used to establish the distribution of recharge and overburden in the

groundwater flow model.

G-2.2.2 Well Data Analysis

MOE Water Well Record (WWR) data were analyzed along with logs of municipal wells to define the

geology and hydrogeology of the study area. The WWR data, however, are known to contain some

information of uncertain quality so a quality control procedure was implemented to filter the WWR data

prior to use. A summary of the MOE data filtering process is presented below.

The MOE WWR database used for this groundwater study contains a total of 6,445 well records. Of the

total number of wells, 23 wells (0.4% of the total) have no location coordinates and 5,107 wells (79%)

have acceptable quality assurance (QA) qualifiers (< or = 6) for both location coordinates and elevation.

The total number of “usable” well records that have acceptable QA qualifiers and contain geologic data

are 5,097. Of the total usable geologic well records, 4,394 wells (86%) identify bedrock in their

stratigraphic/lithologic logs and were used to construct the overburden thickness and bedrock surface

elevation maps presented in this study.

G-2.2.3 Overburden Thickness

The thickness of overburden exerts an important control on the infiltration of precipitation that recharges

the bedrock groundwater flow system. Figure G-5 shows the interpolated thickness of the overburden in

the study area based on the filtered MOE WWR data. Overburden thickness is greater than 10 m over

most of the study area, but varies from zero along the Speed and Eramosa rivers to over 60 m north of

Hopewell Creek. Several discontinuous eskers cross the till plain in a west-northwest direction, the

largest ones being the Ariss, Guelph, and the Eramosa Eskers.

The drumlin field is dissected by a network of sinuous spillway channels of glaciofluvial origin, which

form a dendritic pattern throughout the till plain. The spillway channels are mostly infilled with

glaciofluvial and/or glaciolacustrine sands and gravels that form terrace deposits. The terrace deposits are

most extensive in the area between the Paris Moraine and the Eramosa River. The Arkell Spring Grounds

are developed in the gravel terraces southeast of the City of Guelph. The granular deposits are usually

underlain by Port Stanley Till.

Appendix G: Groundwater Model Development

At some locations, however, the granular deposits lie directly on the dolostone bedrock and comprise the

entire overburden sequence. More complex geologic sequences occur along the northeastern edge of the

Paris Moraine where the till sheets interfinger with ice contact and outwash deposits.

Small streams drain the often swampy valleys between the drumlins. The Eramosa and Speed rivers lie

within larger glacial spillway channels at the front of the Paris Moraine.

G-2.2.4 Bedrock Geology

Bedrock geology for the Guelph area was mapped by Telford (1973). The uppermost bedrock units

underlying the Guelph area are the Silurian age dolostones of the Guelph and Amabel formations. The

Amabel is the older of the two formations and subcrops in the eastern half of the study area. The younger

Guelph Formation subcrops to the west. Outcrops of the Amabel Formation are found along Blue Springs

Creek and along the Eramosa River between Rockwood and Guelph. Outcrops of the Guelph Formation

occur along the Speed River to the north and south of Guelph.

The Guelph Formation is a brown to grey, porous, medium to massive, irregularly bedded dolostone.

Local water well drillers describe it as brown or grey rock or limestone. Televiewer and caliper logging

completed on municipal wells (i.e., Carter Wells and Burkes Well) for the quadrant studies (JHL, 1998)

show the unit is vuggy and extensively fractured, with numerous bedding plane fractures and occasional

vertical fractures evident. At other locations, such as at the former Silvercreek Well (decommissioned in

the late 1990s to accommodate road construction), the Guelph Formation is massive with few fractures

evident. Vertical fractures are exposed in quarries within the study area and appear to strike northeast

with a subset striking to the west.

In drillers’ logs, the contact between the Guelph Formation and the Amabel Formation is distinguished by

a transition from the light brown to grey of the Guelph Formation to the dark brown to black colouring of

the Eramosa Member of the Amabel Formation. Gamma logs can be particularly useful in locating the

contact because the black, bituminous, fine-grained dolostone layers of the Eramosa Member have a

higher gamma log response. The contact between the two units could not be identified reliably at some

well locations in the northwest quadrant study (JHL, 1995), however, since the distinctive dark brown to

black colouring and characteristic gamma response could not be discerned in the logs. It is possible that

the Eramosa Member is thinner or it has undergone a facies change in this area. Using the Eramosa

Member as a marker bed, the Guelph Formation is about 30 m thick at the Sacco production well in the

west but absent along the Eramosa River east of Torrance Creek, where the Eramosa Member is outcrops.

The Guelph Formation is entirely absent in the eastern portion of the modelled area, in the vicinity of

Rockwood.

The Amabel Formation in the study area is subdivided into two recognizable units, namely the distinctive

Eramosa Member (as noted above) and an underlying massive white to grey-brown dolostone. The lower

unit was referred to in the quadrant studies as the Unsubdivided Amabel Formation and includes the

Wiarton, Colpoy Bay and Lions Head Members.

(22-522 AppG August 2003) G-10

Page 15: Arkell Spring Grounds Grounds Groundwater Supply ... · Final Report Arkell Spring Grounds Groundwater Supply Investigation - APPENDICES prepared for: City of Guelph prepared by:

Appendix G: Groundwater Model Development

Televiewer and caliper logs show that the Unsubdivided Amabel Formation has an upper zone that is

massive and only weakly fractured, a middle zone contained large cavities (possibly reefal structures that

have undergone selective dissolution) and numerous vugs, bedding plane and vertical fractures, and a thin

lower zone of more competent dolostone.

The lower contact of the Unsubdivided Amabel as inferred from the driller’s logs corresponds to a “blue

shale” or “blue rock” identified in some of the deeper municipal wells. The unit occurred at an elevation

ranging between 256 mASL at the Burke Well to less than 230 mASL at the Hauser Test Well. The blue

shale beds noted in the driller’s logs may be the shale beds of the underlying Clinton Group. According

to Telford (1973), the dolostones of the Clinton Group are argillaceous and contain interbeds of shale.

This unit was presumed to have a lower permeability than the overlying dolostones and was therefore

selected as the lower bounds of the groundwater flow model. The assumption that the rocks of the

Clinton Group form a barrier to groundwater flow below the Amabel Formation is consistent with the

results of hydraulic testing conducted by Nadon and Gale (1984) and Clarke and others (1989) at quarries

close to the Niagara Escarpment.

G-2.2.5 Bedrock Topography

The bedrock topography map based on MOE WWR data is presented in Figure G-6. The elevations of

the contact between the overburden and the uppermost bedrock unit could be distinguished in well logs

from numerous private and public supply wells in the area. Bedrock topography for the Guelph area has

been mapped by Karrow and others (1979). The available mapping was revised where appropriate using

the geologic logs for the wells installed as part of the Arkell Spring Grounds Investigation.

The bedrock surface slopes gently to the southwest at a rate of about 2 to 3 m/km. Land surface

topography and the present-day drainage features closely follow the bedrock topography. Interpreted

bedrock valleys identified based on bedrock topography, are also shown in Figure G-6.

G-2.3 Hydrogeologic Setting

The overburden and bedrock units have been differentiated based on their hydrogeologic properties into

either aquifers or aquitards as shown schematically in Figure G-2. The aquifers and aquitards identified

in the study area, along with a summary of their hydrogeologic properties are described below.

G-2.3.1 Overburden

Low permeability materials, predominantly glacial tills, are fairly continuous over the study area. The

tills behave as aquitards, which impede the horizontal and vertical movement of groundwater.

Appendix G: Groundwater Model Development

Where the till is at surface, the groundwater recharge potential is reduced, except in areas of hummocky

topography along the top of the Paris and Galt Moraines where stormwater runoff is trapped and, over

time, the water infiltrates into the soil to recharge the groundwater system.

The Port Stanley Till (formerly identified as the Wentworth Till in Karrow (1968)) is the primary aquitard

in the study area. It forms the surface cover of the till plain and the cores of the drumlin hills west of the

Paris Moraine. It also forms the hummocky topography of the Galt and Paris moraines in the

southeastern part of the study area. The Port Stanley Till is classified as a sandy till. An analysis of 25

samples by Karrow (1968) showed that about 49% of the till was sand. The remainder was a mix of 18%

clay and 33% silt. The composition of the till is consistent with its designation as an aquitard. Older tills

may underlie the Port Stanley Till at depth. Discontinuous lenses of sand and gravel can occur within the

till units but are not significant from a regional flow perspective.

Glacial outwash and kame deposits occur in the southeastern part of the study area. The larger sand and

gravel units form aquifers that are tapped by many private and municipal wells. These areas also have

high groundwater recharge potential.

Glacial outwash infills topographic lows and erosional valleys formed by meltwater channels that drained

the ice front at the edge of the Paris Moraine. The outwash sands and gravel are generally underlain by

Port Stanley Till. The major exception is the thick sand and gravel kame deposits that extend from the

Paris Moraine to the Speed and Eramosa river valley. These deposits interfinger with the till of the

moraine and, in several locations, are in direct contact with the bedrock (i.e., along Torrance Creek, the

Arkell Glen, and on the flanks of the Speed and Eramosa river valleys). Erosion of the ice contact deposit

by an ancestral channel of the Eramosa River formed a distinctive erosional scarp along the south bank of

the river.

G-2.3.2 Regional Groundwater Flow

The Guelph-Amabel Aquifer system extends from Niagara Falls to the Bruce Peninsula. In the Guelph

region, it extends eastward to the Niagara Escarpment and westward to the Kitchener-Waterloo area,

where it is overlain by the Salina Formation and contains poor quality water. The thickness of the

Guelph-Amabel Aquifer system ranges from 40 m in the eastern part of the study area to over 90 m in the

west. Water quality is generally good, although the water is hard (high calcium and magnesium content)

and can be high in iron locally.

The permeability of the aquifer is due primarily to the dissolution of dolomite along fractures and bedding

planes. Fracture patterns can be highly variable and, therefore, hydraulic conductivity can vary widely.

The upper part of the aquifer system is generally more permeable than the lower part. Hydraulic

conductivity values for bedrock wells were tabulated in BCE (1991) and ranged from 0.0053 m/d at the

Dawn Avenue well to 79 m/d at the University of Guelph well. The geometric mean of the values was

1.0 m/d.

(22-522 AppG August 2003) G-13

Page 18: Arkell Spring Grounds Grounds Groundwater Supply ... · Final Report Arkell Spring Grounds Groundwater Supply Investigation - APPENDICES prepared for: City of Guelph prepared by:

Appendix G: Groundwater Model Development

Potentiometric surface maps for the shallow and deep zones of the Guelph-Amabel Aquifer were

developed using static water level data from the MOE WWRs database. The 5,097 “usable” well records

were further filtered to identify wells with high quality ground elevations. The recorded land surface

elevations were compared against the DEM (calculated for a 100 m grid spacing) and those wells that

showed a greater than 10 m deviation from the DEM were rejected. The DEM referenced wells were then

filtered to identify a subset of 1,428 higher quality records (28%) where the recorded bottom of the well is

at a depth of less than 30 m below ground surface (bgs). Within the study area, this represents the

average depth to the centre of the semi-confining Eramosa Member of the Amabel Formation. From this

subset of records, the static water levels at the time of well installation were interpolated to construct the

Overburden/Shallow Bedrock Potentiometic Surface map shown in Figure G-7. Filtering of the deep

bedrock zone identified 725 higher quality records (14%) where the top of the well screen or open well

bore interval is below 30 m bgs. The records from this subset were used to construct the Deep Bedrock

Potentiometric Surface map shown in Figure G-8. The contoured surfaces presented in the figures were

generated using kriging, a widely accepted interpolation method (see Davis, 1973).

Figure G-7 is consistent with the groundwater gradient map from Turner (1978) and shows that

groundwater flow follows a general north-to-south trend and is strongly influenced by upwards discharge

to the Speed and Eramosa rivers. Turner (1978) did not distinguish between the shallower groundwater

system in the Guelph Formation and the deeper groundwater system in the Lower Amabel Aquifer, which

is less influenced by the local streams. The Deep Bedrock Potentiometric Surface map (Figure G-8)

developed using MOE WWR data is consistent with the potentiometric maps developed for static

conditions measured in the four quadrant studies for the City of Guelph.

The regional trends and water levels from these maps were used to determine a reasonable limit for the

original model extent. As noted, the model was expanded to include additional surface water basins to

ensure that the model could correctly simulate induced groundwater flow beneath surface water divides.

G-3. Numerical Model Development

Steady-state hydraulic heads (also referred to as aquifer potentials or groundwater levels) within the study

area are controlled by stratigraphy, the magnitude and spatial variation in hydraulic conductivity and the

rate and distribution of recharge and discharge. The groundwater flow model developed in this study

incorporates this information and solves a mass-balance equation to determine aquifer potentials at all

points within the study area. The resultant groundwater levels can then be interpreted (using Darcy's

Law) to determine the rates and direction of groundwater flow. While groundwater levels are known to

vary on a seasonal and year-to-year basis, model development was limited to an analysis of long-term

average (steady-state) conditions.

This section briefly describes (1) the governing steady-state groundwater flow equation, (2) the

groundwater flow model selected for this study, (3) the finite-difference grid and model layering, (4)

interpolation of layer surfaces, (5) specification of boundary conditions, and (6) preparation of input data

on the rates of groundwater recharge and discharge.

G-3.1 Groundwater Flow Theory

The general mass balance equation for steady-state groundwater flow can be stated as:

Sum of Boundary Inflows + Sum of All Internal Sources of Water =Sum of Boundary Outflows

Mathematically, the equation of mass balance for two-dimensional flow in a confined aquifer with

recharge, discharge, and leakage from above and below can be written as (Bear, 1979):

Appendix G: Groundwater Model Development

Similar equations can be written for each aquifer in a layered sequence of aquifers and confining units.

When an aquifer layer is unconfined, the transmissivity is replaced by the effective transmissivity, equal

to Kxx(h-b) where b is the base of the aquifer layer. The USGS MODFLOW code (McDonald and

Harbaugh, 1988) used in this study applies Equation 1 when simulating two-dimensional or quasi-three-

dimensional flow. When simulating fully three-dimensional flow, MODFLOW uses the leakage terms in

Equation 1 to represent vertical flow between aquifer sub-layers.

Equation (1) formed the basis of the mathematical model developed for the study area. This equation is

solved by the MODFLOW code to determine aquifer potentials based on the aquifer properties, recharge

and discharge rates, and conditions along the study area boundaries specified. A numerical model is

needed to solve Equation (1) because study area boundaries are irregular and aquifer properties,

stratigraphy, and rates of recharge and discharge vary spatially within the study area.

G-3.2 Model Limitations

Although MODFLOW is capable of simulating both transient and steady-state flow; the model developed

for this study simulated only steady-state flow. Steady-state simulations are a simplification of the actual

transient flow system. The various transient effects, such as daily or seasonal fluctuations in aquifer

potentials, rates of precipitation and evapotranspiration and surface water levels, have been removed from

the model by using average values for each parameter. For example, precipitation and the water level in

the Eramosa River were represented using annual average values. The steady-state model provides a

good representation of annual average groundwater flow conditions.

MODFLOW is applicable for simulating groundwater flow through either porous media (i.e.,

unconsolidated sediments) or bedrock that contains a network of fractures that transmits groundwater

according to Darcy’s Law. The characterization of a fractured bedrock as a hydraulic continuum is

typically scale related, but is appropriate for regional to a sub-regional scale (scale of the well-head

capture-zones) modelling (Anderson and Woessner, 1992). While there are likely to be circumstances

where the continuum approach for characterizing groundwater flow may not be applicable at the local

scale (e.g., simulating drawdowns at individual wells where the well response is strongly affected by

individual fractures), in general, most municipal wells in the study showed hydraulic response consistent

with the interpretation of an interconnected fractured network (i.e., a continuum).

Geologic systems tend to be complex due to the highly variable physical properties of rock and soil.

Because there are usually only a limited number of boreholes available to characterize a site, there is

always a level of uncertainty regarding how representative the measured values are of the average

properties in the vicinity of the borehole and how property values change between boreholes. Other

uncertainties can arise related to how well groundwater recharge and discharge rates can be measured or

estimated. Data limitations can also affect the quality of the model calibration. Lack of data in critical

areas of the model can reduce the number of unique parameter zones that can be represented and can lead

to non-unique model calibrations.

Appendix G: Groundwater Model Development

The predictions made by the numerical model, which represents a simplification of the true physical

system, are therefore limited to an extent depending on the nature of the simplifying assumptions used in

model development. As noted, the most significant simplifying assumptions made in model development

are related to the limited availability and uncertainty in the field data. Despite these limitations, a well-

calibrated groundwater model can be used to provide insight into the factors that influence groundwater

flow in a particular area and can be applied to predict the effects of proposed water takings on local water

levels and discharge to streams. In general, a well-calibrated groundwater model can accurately simulate

average water levels, gradients, and flow directions. Predictions of flow paths and well capture zones,

however, are less certain since actual flow paths and capture zones can be significantly affected by small-

scale variations in geology and aquifer properties and the presence of individual fractures that are not

represented in the model.

G-3.3 Modelling Environment

The MODFLOW code used in this study was based on the MODFLOW-88 version documented in

McDonald and Harbaugh (1988). In addition to MODFLOW, the USGS MODPATH code as

documented in Pollock (1989) was used to simulate groundwater flowpaths and define capture zones.

The MODPATH code uses the aquifer potentials determined by MODFLOW along with other data to

determine groundwater time of travel for municipal well capture analyses.

The VIEWLOG data management system (Version 2.3, VIEWLOG Systems, Inc.) was used to pre-

process the model input data and post-process model results (VIEWLOG documentation available at

www.viewlog.com). Most figures presented in this technical report were generated using VIEWLOG.

Appendix G: Groundwater Model Development

G-4. Numerical Model Development

G-4.1 Model Setup

The model uses a variable horizontal grid spacing varying from 50 metres (m) at the centre of the model

area to 1,600 m at the perimeter of the model domain. The average grid spacing within the model is 200

m. This 200-m grid spacing resolution is appropriate to conduct regional-scale simulations. Similar

scales were used by the GRCA in their regional flow modelling of the Grand River Basin. A finer-

resolution was used in the vicinity of the streams and around wellfields to better represent drawdowns

around the pumping wells and improve delineation of capture zones for production wells.

G-4.1.1 Flow Boundaries

The boundaries of the regional model are shown in Figure G-9. The model uses both “no-flow” and

“constant head” boundary conditions on the perimeter of the active model area. Model boundaries along

sub-watershed boundaries are treated as no-flow boundaries, where the rate of flow across the model

boundary is assumed to be small or equal to zero. It was felt that some of the sub-watershed boundaries

used in the original model (see Figure G-1) and subsequent expansion for the Guelph-Eramosa Township

may have been too close to the Arkell Spring Grounds area. The model boundaries were therefore

expanded to include the Township of Guelph/Eramosa, portions of the Townships of Puslinch, Woolwich

and Centre Wellington and a portion of the Town of Erin that includes Blue Springs Creek. The no-flow

boundaries were used along sub-watershed boundaries, where present, perpendicular to contours of equal

head as identified by the Grand River Conservation Authority (GRCA, 2001) and in the bedrock

groundwater potentiometric head maps (Figures G-8 and G-9).

Constant head boundary conditions were applied to all layers at a limited number of locations along the

model boundaries, primarily to represent streams crossing into or out of the model area. Constant head

boundaries were also applied to areas where sub-watershed boundaries were not present based on

contours of equal head potential in the bedrock aquifer as identified by GRCA (2001) and in Figures G-8

and G-9. These boundaries are located a sufficient distance from the study area such that changes in

pumping within the study area should not change assumed heads on the boundary. Constant heads were

also used to represent the Guelph Lake in Layers 1 and 2. As noted, the model boundaries are presented

in Figure G-9.

Head-dependent boundaries are used within the model area to simulate groundwater/surface water

interaction where groundwater is gained from (or lost to) a partially penetrating stream or river as leakage

across the streambed. The streambed is assumed to be less permeable than the surrounding aquifer due to

deposition of layers of fine-grained sediments or organic material.

Appendix G: Groundwater Model Development

The Eramosa River, Speed River and the main stems of Hanlon Creek and Blue Springs Creek (see Figure

G-9) are simulated as head-dependent recharge/discharge boundaries, using the MODFOW River

Package, where groundwater can flow into or out of the model depending on the hydraulic gradient at the

applicable grid nodes in the model. All other small streams, creeks and the Arkell Glenn Collector

Trench (see Figure G-9) are simulated as head-dependent drains using the MODFLOW Drain Package,

where groundwater can only flow out of the model at rates dependent on the hydraulic gradient at the

applicable model cells. A summary of the input parameters for the MODFLOW River and Drain

Packages are presented in Table G-1.

Page 27: Arkell Spring Grounds Grounds Groundwater Supply ... · Final Report Arkell Spring Grounds Groundwater Supply Investigation - APPENDICES prepared for: City of Guelph prepared by:

Appendix G: Groundwater Model Development

When the water table is above the specified surface water elevation, both the river and drain boundaries

allow groundwater to discharge from the groundwater system. When the water table drops below the

surface water elevation of a river boundary, water is allowed to recharge into the groundwater system. If

the water table drops below the streambed, then a fixed flux, based on a maximum 1-meter head

difference between the surface water elevation and the streambed bottom was applied. When the water

table drops below the surface water elevation of a drain boundary, no flow is allowed to recharge into the

groundwater system (i.e., flow is allowed from the aquifer to the drain only).

Cells within the active model domain can go “dry” during a simulation if the water table drops below the

base of the layer. These cells are then treated internally by MODFLOW as inactive cells since they no

longer contribute flow to the rest of the model area. The number of dry cells and their locations varied in

each of the model simulations in response to changes in model input conditions. The MODFLOW re-

wetting option (McDonald et al., 1991) was used to allow a cell to become active again if potentials in

neighboring cells were higher than the base of the dry cell. Re-wetting parameters were modified during

the course of the calibration to improve model stability and to speed the process of model convergence.

G-4.1.2 Extraction Wells

Extraction wells were incorporated into the model as detailed in Table G-2. The list of extraction wells

includes municipal water wells and private wells exceeding a permitted rate of 200,000 L/day. Referring

to Table G –2, this cut-off represents about 0.3% of the total quantifiable pumping. The locations of the

well are presented in Figure G-9. Average pumping rates for the City wells from 2000 were used. The

combined rate of production from these wells for 2000 is estimated to be approximately 10% higher than

the combined rate since 1997. Other municipal and private takings were applied at their permitted

pumping rates.

G-4.1.3 Groundwater Infiltration/Recharge

The total average annual precipitation measured at the Guelph Arboretum from 1971 to 2000 was 923

mm/year (Environment Canada, 2002). Applying the Thorthwaite water balance equation

(Thornthwaite, 1948), the annual potential evapotranspiration is estimated to be 53%, or 487 mm/year. A

limitation of the Thornthwaite water balance equation is that it neglects winter evapotranspiration. An

independent calculation of long-term water balance for the Upper Speed River for the same period of

record estimates a higher evapotranspiration of about 59%, or 540 mm/year (Whiteley, in preparation).

The remaining portion of precipitation from these two estimates of 383 to 436 mm/year is the water

surplus for this area. Part of the water surplus will end up as surface runoff to area watercourses and the

balance will infiltrate through the soil profile and eventual recharge the shallow groundwater.

Appendix G: Groundwater Model Development

Locally, rates of groundwater recharge vary depending on soil type, topography, and land use. Data on

land use, climate, and soil properties were collected and analyzed in the quadrant studies to provide initial

estimates of the spatial distribution of groundwater recharge. These initial estimates were refined by

Gartner Lee Limited using the HELP hydrologic model to provide recharge rates for different

combinations of soil types and land use categories.

Net average recharge to the groundwater system was simulated using the RECHARGE module for

MODFLOW. Initial estimates of recharge rates were assigned to groups of model cells representing the

different soil property zones as determined from the digitized map of surficial geology (Figure G-10).

The glacial tills, with hummocky topography, were assigned higher recharge rates. Recharge rates in

urban areas were reduced compared to those in rural areas. Some degree of uncertainty was assumed to

be associated with these initial estimates. Recharge rates, as outlined in Table G-3 and Figure G-10, were

adjusted slightly during the process of model calibration. Model sensitivity analyses were conducted after

the model calibration by scaling the recharge rates. Simulations were also conducted to determine the

response of the groundwater system to extreme wet or dry climatic conditions.

G-4.1.4 Preparation of Model Layer Surfaces

The numerical model developed for the study area incorporated detailed information on the stratigraphy

of the aquifers and aquitards. Six layers were used in the groundwater flow model to represent the flow

units identified in the study area (see Figure G-2). Model layers are discussed further in the next section.

Preparation of the surfaces representing the tops and bottoms of each layer took considerable effort and

included: (1) analyzing MOE WWR and City of Guelph borehole logs; (2) identifying the top and bottom

of each aquifer layer and aquitard; (3) interpolating the point elevation data to the finite-difference grid;

(4) checking the generated surfaces; and, (5) correcting surfaces by slightly adjusting elevations where

required.

The layers in the original 1999 model were based on borehole data contained in the draft reports for the

quadrant studies (JHL 1993, 1995, 1997, and 1998) along with other relevant data in the Hanlon Creek

(Marshall, Macklin, Monaghan, 1992), Puslinch (Gartner Lee Associates Limited, 1986a), and other

Guelph water supply reports (BCE, 1991 and GLAL, 1986b). Geologic logs, gamma logs, and televiewer

logs for the municipal supply and observation wells were examined by Gartner Lee to determine: 1) land

surface elevation at each well; 2) the top of the Guelph aquifer; 3) the top of the Eramosa unit; 4) the top

of the Amabel aquifer; 5) the top of the “production zone” within the Amabel aquifer; 6) the bottom of

the production zone; and 7) the top of the lower shale unit that served as the base of the Amabel aquifer.

The ground surface layer of the 2003 model, presented in Figure G-3, was developed applying the DEM

used in the Guelph-Eramosa Township Groundwater Study (Gartner Lee, 2003). The top of bedrock

layer, presented in Figure G-6, was developed using the top of the first bedrock unit encountered in the

screened WWRs (database of 4,394 MOE WWRs).

Appendix G: Groundwater Model Development

Higher quality lithology logs selected from the MOE WWR database were identified as part of the

Guelph-Eramosa Township Groundwater Study (Gartner Lee Limited, 2003) and used to identify

stratigraphic layers within the 2003 model. The selected wells included deep well records that contain

sufficient stratigraphic detail to identify the individual units (i.e., Guelph Formation, Eramosa Unit, and

Unsubdivided Amabel) based on colour and lithology. Table G-4 presents a list of the higher quality

lithology logs used to generate the stratigraphic contacts used in the model. The bedrock formation

contact surfaces developed for the model are presented in Figures G-11 through G-13.

Stratigraphic contacts for the wells were interpolated to the centre of each finite-difference cell using a

technique called “universal kriging” (see Davis, 1973). Variance analysis and fitting of the theoretical

variograms was done within the VIEWLOG data management system. In universal kriging, an estimate

of the trend (drift) is first determined, subtracted from the raw data, and then a variogram is fitted to the

residuals. This process is iterative, since the updated values for the drift and residuals are used to improve

the fit of the variogram. The stratigraphic layers developed for the 2003 model were checked for

consistency with the original layers developed for the 1999 model.

Appendix G: Groundwater Model Development

The VIEWLOG data management system was used to interactively check and correct the interpolated

surfaces where any interpolated surfaces crossed. Crossovers occurred most often near the bedrock

valleys, where the interpolated bedrock surface cut across the interpolated surfaces for the lower layers.

G-4.1.5 Model Layers

The model incorporates six layers to simulate the complex hydrogeology (as shown in the conceptual

model Figure G-2) that is present in within the region. The layers are as follows:

Layer 1 – represents the overburden;

Layer 2 – represents the Guelph Formation (the upper bedrock aquifer referred to as the Guelph

Aquifer) which is found across most of the study area;

Layer 3 – represents the Eramosa Member of the Amabel Formation, (an aquitard that impedes the

vertical flow of groundwater between the upper and lower bedrock aquifers) which is present

across most of the study area but is absent in the southeast portion;

Layer 4 - represents the upper zone of the Unsubdivided Amabel Formation (the lower bedrock

aquifer herein referred to as the Amabel Aquifer) which is present across the entire study area;

Layer 5 - represents the highly cavernous zone of the Amabel Formation (a highly productive zone

of the Amabel Aquifer) identified in several areas; and,

Layer 6 - represents the hydrogeologic characteristics of the lower zone of the Unsubdivided

Amabel Formation (a less productive zone of the Amabel Aquifer).

The interpreted extents of the Guelph Formation and the Eramosa Member of the Amabel Formation are

also shown in Figure G-11. The Guelph Formation and Eramosa Member are absent in the vicinity of and

south and east of Rockwood, based on Blue Springs Creek watershed reports (MOE, 1978; Stantec, 1999)

and available borehole stratigraphy from water well records. Since MODFLOW requires each model

layer to be continuous across the grid, the thickness of Layer 2 (representing the Guelph Formation) was

reduced to 0.1 m in these areas.

G-4.1.6 Model Parameters

The hydrogeologic characteristics of the overburden (Layer 1) were defined using estimated hydraulic

conductivities based on the soil types shown in the surficial geology map. Initial estimates for the

different soil types were based on ranges provided in Freeze and Cherry (1979) and refined during the

process of calibrating the 1999 model. Calibration of bedrock hydraulic conductivities in the 1999 model

was done by first simulating pre-development conditions (i.e., no pumping) and comparing with Turner

(1978) to ensure that the hydraulic conductivities and recharge rates selected yielded a reasonable match

to regional flow patterns. Next, a composite of the static water levels, as determined in the well shutdown

tests for each quadrant, was matched. This resulted in an initial definition of higher and lower

permeability zones within the bedrock aquifer layers. Separate simulations of each shutdown test were

then used to refine the hydraulic conductivity values and leakage factors in each quadrant.

(22-522 AppG August 2003) G-36

Page 41: Arkell Spring Grounds Grounds Groundwater Supply ... · Final Report Arkell Spring Grounds Groundwater Supply Investigation - APPENDICES prepared for: City of Guelph prepared by:

Appendix G: Groundwater Model Development

Further adjustments of hydraulic conductivities for the bedrock units were done during the

Guelph/Eramosa Township Groundwater Study and subsequently, in this study to better match observed

hydraulic heads. The hydraulic conductivities used for the regional model are presented in Table G-3 and

Figures G-10, G-14 and G-15. Where the Guelph Formation is known to be absent, the hydrogeologic

parameters of Layer 2 were set equal to that of Layer 3 or 4 (Eramosa Unit, if present, otherwise Upper

Amabel). Vertical leakage between layers was specified according to the hydraulic conductivity

anisotropy ratios presented in Table G-3. Anisotropies ratios were selected based on results of calibrating

the 1999 model. No leakage occurs between the Amabel Aquifer and the underlying formations of the

Clinton Group in the model.

Zones of higher hydraulic conductivity were input along portions of several major and minor bedrock

valleys, which were believed to be areas of greater fracturing. Larger zones of higher hydraulic

conductivity were placed in locations where bedrock valleys and existing rivers coincide. Aquifer test

results from pumping tests conducted at several City of Guelph test wells in Arkell Spring Grounds in

2000 and at the Township of Guelph/Eramosa Test Well (TW3/02) in Rockwood in 2002 were used to

help refine and verify hydraulic conductivity values selected for those general areas.

The hydraulic conductivity values selected to represent the Amabel Aquifer in the Arkell Spring Grounds

area were based on the results from short-term pumping tests conducted by the City of Guelph at

observation wells OW #11/2000 through OW#18/2000 during 2000. These pumping test results indicated

transmissivities of approximately 0.02 m2/s at wells OW#14/2000 and OW#15/2000 and approximately

0.01 m2/s at wells OW#11/2000, OW#12/2000 and OW#18/2000. These measured transmissivities are

considered representative of the highly productive cavernous zone of the Amabel Aquifer that is present

at an elevation of approximately 295 mASL in this area. The transmissivity values were converted to

hydraulic conductivity values 0.004 m/s and 0.002 m/s by dividing by 5 m (the thickness of Layer 5) and

were applied to Layer 5, as shown in the lower portion of Figure G-11. A hydraulic conductivity of

1.0x10-5 m/s was applied to the upper and lower zones of the Unsubdivided Amabel Formation (Layers 4

and 6) within the Arkell Spring Grounds area.

A higher hydraulic conductivity of 5x10-4 m/s was applied to Layer 5 of the model in the southern and

eastern portions of the modelled area. This value was selected based on model calibration and is only

slightly higher than that estimated from a 72-hour pumping test conducted at TW3/02 by Burnside

Environmental (2002). Results of the pumping test indicated the productive cavernous zone of the

Amabel Aquifer that is present at an elevation of approximately 305 mASL has a transmissivity of

approximately 4.3x10-4 m2/s to 1.3x10-3 m2/s. Assuming the thickness of the cavernous zone is 5 m, the

highest transmissivity converts to a hydraulic conductivity of 2.6x10-4 m/s. The hydraulic conductivity

used in the model is in the same order of magnitude as measured. A hydraulic conductivity of 1 10-5 m/s

was applied to the upper and lower zones of the Unsubdivided Amabel Formation (Layers 4 and 6) within

the southern and eastern portions of the modelled area.

Appendix G: Groundwater Model Development

G-4.2 Model Calibration

The groundwater flow model was calibrated to hydraulic head maps generated for shallow and deep

bedrock zones using data from MOE water well records (Figures G-7 and G-8), as part of the

Guelph/Eramosa Groundwater Study (Gartner Lee, 2003). Groundwater discharge to selected rivers and

streams was compared to average groundwater baseflow estimates from the Guelph All-Weather

Sequential-Events Runoff (GAWSER) model used by GRCA. The calibration of the model is primarily

dependent on the recharge and hydraulic conductivity parameters. In general, the range of possible

recharge values is much smaller than the range of uncertainty in hydraulic conductivity values.

Therefore, calibration was conducted by selecting reasonably conservative estimates for recharge and

adjusting the hydraulic conductivity parameters to match the observed heads.

G-4.2.1 Sub-Watershed Mass Balance

A sub-watershed mass balance was conducted by comparing the model mass balance during pumping

conditions with the volume of baseflow from groundwater discharge to rivers and streams at several river

gauge stations. Groundwater baseflow discharge to rivers was estimated by GRCA (2002b) for

Armstrong Mills, Eramosa at Watson Road, Speed River at Hanlon and Blue Springs Creek at Eramosa

River gauge stations (shown in Figure G-2) using the GAWSER model. The stream flow data provided

by the GRCA for the Eramosa River covers the period between 1962 and 2000. The Arkell Spring

Grounds wells were operational over most of this period beginning in the mid to late 1960’s.

The GAWSER model results were used to separate annual average storm water runoff into the streams

from annual average baseflow that can be attributed to groundwater discharge. Stream flow rates

recorded more than 20% of the time were considered to be representative of the annual average stream

baseflow. The ranked flow duration plots for these stations were obtained from the GRCA are presented

in Figure G-16. The GRCA estimated average stream baseflow using two methods to provide a range of

values as follows:

all stream flow rate measurements that occur more than 20% of the time were averaged to provide

the annual average baseflow; and,

by approximating a triangle between 20% and 100% on a graph of flow rate versus percent time,

the value at 1/3 of the triangle area (approximately 46.7%) was taken as the annual average

baseflow.

Groundwater baseflow estimated by GRCA for the four gauge stations is provided in Table G-5.

Average annual baseflow was calculated by GRCA to be:

(1) the average flow between 20% and 100%; and,

(2) the value at 46.67% (the point representing 1/3 the area of a

triangle approximating the area beneath the line between 20% to

The estimated groundwater baseflow contribution to the Speed and Eramosa Rivers between the gauge

stations at Armstrong Mills/Eramosa at Jones Baseline and Speed at Hanlon from the groundwater flow

model is 0.96 m3/s. The mass balance from the model is within the GRCA estimated range for the same

sub-watershed area. The modelled flow from Blue Springs Creek only is 0.49 m3/s and only slightly

exceeds the higher of the two GRCA estimates.

A summary of the model mass balance is presented in Table G-6. Overall, the mass balance error (water

coming into the model by recharge and baseflow minus water leaving the model via discharge to rivers

and groundwater production wells) is about 0.01%. This mass balance error is well below the ideal

criterion suggested by Konikow (1978). The low mass balance error demonstrates that the model

converged to a correct solution. For the entire model area, approximately 89% of the available

groundwater (recharge plus additional baseflow) is discharged to rivers and streams and 11% is captured

by major groundwater takings included in the model. Within the modelled portion of the Eramosa River

groundwater-shed, shown in Figure G-17, the volume of groundwater that discharges to the rivers and

streams represents approximately 76% of the available groundwater and major groundwater takings

represents approximately 24% of the available groundwater.

G-4.2.2 Calibration to Regional Groundwater Heads

Groundwater hydraulic head maps were developed for an overburden/shallow bedrock zone and a deep

bedrock zone as part of the Guelph-Eramosa Groundwater Study. The overburden and shallow bedrock

zone includes water wells that are screened/completed entirely between 0 m to 30 m bgs. The deep

bedrock zone includes water wells that are screened/completed entirely below 30 m bgs.

Appendix G: Groundwater Model Development

The modelled hydraulic head contours for the shallow and deep bedrock zones with groundwater

pumping incorporated into the model according to Table G-2 are presented in Figures G-18 and G-19

respectively. A comparison of the modelled contours to the contours of observed hydraulic head (see

Figure G-7 and G-8) indicates that the model simulates the recorded heads reasonably well. To assess the

goodness-of-fit of the model, the recorded hydraulic head at overburden/shallow bedrock zone and deep

bedrock zone wells were statistically compared to the hydraulic head simulated by the model for the

shallow and deep zones. The shallow bedrock zone is represented by Layer 2, where the Guelph

Formation is present and Layer 3 where the Guelph Formation is absent (i.e., the Arkell Spring Grounds,

Rockwood and Blue Springs Creek areas). The deep bedrock zone is simulated by Layer 5. As indicated,

Layer 5 represents the deeper productive zone of the Amabel Aquifer, where it is characterized as

cavernous with a high permeability.

The groundwater model was calibrated to provide a reasonable match to recorded hydraulic head

conditions during both non-pumping and pumping conditions. By making minor adjustments to bedrock

permeability and groundwater recharge, the model was able to match the observed data on existing

aquifer potentials and hydraulic gradients. Calibration statistics used to assess the accuracy of the model

are described below.

where: ho = Observed hydraulic head;

hm = Simulated hydraulic head; and,

n = Number of wells.

The residual error between observed and modelled hydraulic head was analyzed to assess the goodness of

fit and distribution of the error. Probability plots of the residual errors for the shallow zone and deep

bedrock zone are presented in Figure G-20. The 50% probability, or average residual error, plots just

below residual value of 0 in both plots, indicating a very small error relative to the entire residual error

range. (The average residual error is less than 0.5 m for the shallow zone and less than 1.5 m for the deep

bedrock zone.) Spitz and Moreno (1996) indicate that having the average error to be within 10% of the

scale of the observations is an appropriate measure of calibration. In this case, the scale of observed

residuals is approximately 40 m and 10% of the range is 4 m.

The effect of simulating non-pumping conditions was found to have only a minor effect on the average

error data by increasing the average error by up to 1 m. The resulting error analysis for non-pumping

conditions is still well within the 10% error criteria of 4 m used in this calibration.

Appendix G: Groundwater Model Development

The probability plots also help assess the validity of the calibration by determining whether the residual

errors are distributed normally around the mean and if there are any anomalous data that should be

considered outliers and removed from the data set. The data follow relatively straight lines in both plots;

however, several data points that are circled on Figure G-20 show an obvious change in slope from the

rest of the data. These data points were considered outliers and removed from the data set that was used

to conduct additional statistical analysis. Three data points were removed from the shallow zone analysis

and 13 data points were removed from the deep zone analysis. A listing of all the data (including outliers)

is presented in Appendices G-1 and G-2.

The regional scale calibration results were also analyzed using scatter plots, presented in Figures G-21

and G-22 for the shallow and deep zones respectively. The scatter plots showing observed versus

modelled head for each of the groundwater-sheds (except Mill Creek) included in the model (see Figure

G-17). No comparison is made for Mill Creek groundwater-shed as no MOE WWRs were available for

this area at the time of this study. Calibration of the Mill Creek groundwater-shed was conducted by

matching the groundwater-shed boundaries identified by GRCA (2001) and shown in Figures G-18 and

G-19. (A groundwater-shed is defined as the portion of the groundwater system that contributes baseflow

to a stream.)

The data from Blue Springs Creek are shown separately from the Eramosa River data in Figures G-21 and

G-22 to demonstrate the goodness of fit in this area. Error bands, representing 10% (+/-13 m) of the scale

of the observations (130 m), are presented in the figures to show an acceptable calibration range (Spitz

and Moreno 1996). The results show good calibrations to observed head data, as almost all of the data

points fall between the error bars and are generally balanced around the line of unity.

The mean error is equal to the average difference between the observed values (h0) and simulated values

(hm) and indicates whether simulated values are generally higher (indicated by negative value) or lower

(indicated by a positive value) than the observed values. The mean absolute error is equal to the average

magnitude of the difference between the observed and simulated values. These statistics were calculated

for the modelled portions of the Grand River groundwater-shed, the Speed River groundwater-shed and

the Eramosa River groundwater-shed.

Results of the statistical analysis shown in Table G-7 indicate that the average error between static

regional heads and simulated heads for the model is 0.45 m and 1.29 m for the shallow bedrock and deep

bedrock zones, respectively. The model overestimates the observed static shallow bedrock potentiometric

heads in the Grand River and Eramosa River groundwater-sheds and slightly underestimates the

potentiometric heads in the Speed River groundwater-shed. For the entire model area, the model

overestimates the observed static potentiometric heads in all three groundwater-sheds.

G-4.2.3 Assessment of Model Calibration in the Vicinity of the Arkell Spring

Grounds

The locations and observed hydraulic head data for July 12, 2001 along with predicted values are

presented in Table G-8. Figures G-23 and G-24 present the July 12, 2001 groundwater hydraulic head

data and the simulated potentiometric surfaces for the Guelph/Eramosa Unit and Amabel Aquifer,

respectively. (Note: Water levels measured on July 12, 2001 were assumed to represent the pre-test

steady state condition because the municipal wells were being pumped at rates similar to their historical

long-term pumping rates.) The red data points in the figures represent wells where the model

overestimated the observed head and green data points represent wells where the model underestimated

the observed head. The local scale calibration results are also presented in a scatter diagram in Figure G-

25 showing observed versus modelled head in the Amabel and Guelph/Eramosa Units. The scatter

diagram also shows the 10% error bars (+/- 3 m) around the line of unity. The calibration results show

substantial scatter in the data around the line of unity for monitoring wells installed in both zones. The

greater scatter evident in the Guelph/Eramosa data may be due to local features that are not accounted for

in the regional model. Less scatter is evident in the Amabel data, as there appears to be substantial

hydraulic interconnection between these wells.

The average simulated hydraulic head for the Guelph/Eramosa well ID numbers 16, 18, 24, 27, 34, 39, 55,

74, 75, 79, 80 and 83 is approximately 0.3 m below the average hydraulic head measurement at these

wells. The average simulated hydraulic head for the Amabel Aquifer at well ID numbers 1, 2, 4, 6, 9, 10,

11, 13, 14, 15, 19, 21, 22, 23, 25, 26, 28, 33, 36, 37, 38, 76, 77 and 85 is approximately 0.2 m above the

average hydraulic head measurement at these wells. The model slightly underestimates the average

hydraulic head in the shallow zone and slightly overestimates the average hydraulic head for the local

scale. The average errors for both zones are substantially less than the error criteria of 3 m.

G-4.2.4 Model Testing: Simulation of 2001 Arkell Spring Grounds Pumping

Test

A long-duration, large-scale pumping test was conducted in 2001 as part of the Arkell Spring Grounds

investigation. The water level data collected during the test provide an opportunity to evaluate the

predictive capability of the calibrated groundwater model.

Figures G-26 and G-27 present the measured hydraulic head and the predicted steady-state hydraulic head

for the end of test Step #4 on September 23, 2001 for the Guelph/Eramosa units and Amabel Aquifer

respectively. Figures G-28 and G-29 compare the predicted drawdown to the average observed

drawdown for the Guelph/Eramosa units and Amabel Aquifer, respectively. The results shown in these

figures indicate that the model predicts an additional 2.6 m of drawdown on average within the

Guelph/Eramosa units and an additional 2.0 m of drawdown on average within the Amabel Aquifer at

steady-state conditions. Comparing the predicted drawdown to the average observed drawdown of 0.9 m

and 4.3 m at wells installed in the Guelph/Eramosa units and Amabel Aquifer respectively, the model

results suggest that steady-state conditions may not have been attained during the test program. Based on

this analysis, the model indicates that the observed hydraulic head in the deep bedrock at the end of the

2001 test has achieved approximately 68% of the total predicted drawdown, while the observed hydraulic

head in the shallow bedrock has achieved approximately 26% of the total predicted drawdown.

The predictions of the calibrated model are consistent with the observations made during the 2001

pumping test. The model overpredicts the drawdowns, but the magnitudes of the predicted drawdowns

are in within the range of the observations. The results of the 2001 pumping test simulations suggest that

the model can be used with confidence to evaluate the effects of additional water takings.

G-5. Calibration Summary Comments

The regional groundwater flow model, developed for the City of Guelph and surrounding area, was

calibrated to observed hydraulic heads and surface water baseflows. The model is considered to be well-

calibrated because it represents the key elements of the physical system within a regional context, the

parameter values used in the model are within physically realistic ranges, and the model provides an

acceptable match to observed data on both regional and local scales.

The model has been used to

estimate the sustainable yield of the Unsubdivided Amabel bedrock formation beneath the Arkell

Spring Grounds;

evaluate the potential for losses from the Eramosa River under increased pumping; and,

delineate the well field capture zone for increased taking at Arkell Spring Grounds.

The results of this work are presented in Section 6 of the body of the main report.

It is anticipated that the model will be a useful tool for assessing the hydraulic effects of any future

alterations to the pumping rates of individual existing and proposed bedrock production wells located in

the Arkell Spring Grounds.
