Title:
Relationship of groundwater recharge rates to aquifer sensitivity to contamination in shallow aquifers in Indiana, using multiple regression analysis

Description:
Abstract:
Aquifer_Recharge_Near_Surface_IN is a raster data layer that displays the results of a regression analysis to determine the estimated rate of diffuse groundwater recharge to the water table in shallow aquifers in Indiana based on numerous landscape-level variables as predictors. The goal of this project was to use an objective, reproducible methodology to estimate groundwater recharge rates in both glaciated and driftless environments. This groundwater-recharge raster layer was developed by combining a multiple regression analysis of groundwater recharge with characteristics of near-surface geologic materials. The groundwater recharge data used in the multiple regression analysis was derived from calculations of groundwater baseflow and surface-water runoff for 279 streams in Indiana. Estimates of groundwater base flow were determined using hydrograph separation analysis (Institute of Hydrology, 1980) determined using a local-minimums approach with a recession slope test, and were converted to recharge by multiplying by using estimates of runoff following Wolock (2003). The baseflow index (BFI) provides the proportion of runoff that is assumed to be groundwater contribution, so recharge was estimated as BFI * interpolated statewide runoff (not runoff per basin). The average annual rate of groundwater recharge (in/year) was used as the dependent variable in a multiple regression analysis using ordinary least squares with several landscape and morphometric independent variables representing geologic, terrain, climate, and hydrogeologic characteristics. The regression model developed for Indiana had a global R2 value of 0.50, and the most influential variables at the 95% confidence level were:

- Cumulative percent area of upstream impervious surfaces - Surface clay thickness - Percent of clay in soil - Average annual air temperature - Presence/absence of unconsolidated aquifers - Slope of ground surface - Cumulative percent area of upstream water bodies - Sand composition of water well boreholes - Cumulative percent area of upstream medium-height vegetation - Hydrologic group classification of soil (A,B,C,D - SSURGO)

The regression model was used as a mapping tool to spatially distribute estimates of recharge across Indiana, incorporating details of the important landscape variables.

Purpose:
This data set was created to support a statistical regression analysis of groundwater recharge rates in shallow unconsolidated aquifers, Indiana.

Process_Step:
Process_Description:
For each variable evaluated, depending on the data type and source scale of the original data, GIS data layers were created in vector or 100-meter raster formats. For this analysis, 279 point locations representing United States Geological Survey stream gages were the focus. For this study, the following attributes were considered: watershed area; contributing area; elevation; slope; compound topographic index; height above minimum base level, depth to groundwater, downslope distance to nearest stream, thickness of shallow clay deposits, weighted saturated soil hydraulic conductivity, soil parent material, soil drainage class, average annual precipitation, average annual maximum temperature, average annual minimum temperature, growing degree days, stream flow, stream density, wetland density, groundwater withdrawals, surface water withdrawals, modeled incoming solar radiation (insolation); land-over classification (agriculture, various types of forest, developed and undeveloped land, wetlands, impervious surface, and so on). The data were used to identify a statistical regression model aimed at predicting the rate of groundwater migration from the surface into the subsurface in Indiana. The values for each independent landscape variable in each analysis cell were tabulated in an Excel spreadsheet, and exported to a text file for use in an external statistical ordinary least squares regression code, In addition, each regression was performed using the ESRI ArcGIS Ordinary Least Squares regression tool (Spatial Statistics Toolbox) to check results and map the spatial distribution of residuals. The models were repeated in R and Excel to obtain different metrics in the output files. The best-fit model achieved an R2=0.50 at the 95% confidence level for the 279 point locations. The model equation was used to spatially distribute (map) the predicted estimates of recharge across the landscape using Raster Calculator in ESRI ArcGIS, at a raster resolution of 100 m.
