Heuristic MODFLOW models used to evaluate the effects of pumping groundwater from confined aquifers overlain by till confining units

This groundwater-flow model archive contains heuristic model simulations evaluating the sustainability of groundwater withdrawals from public-water-supply wells on buried glacial aquifers. A total of 40 steady-state simulations and three transient simulations were run. The steady-state simulations were developed to assess the extent and connections between buried sand aquifers by varying three hydraulic or dimensional properties of the buried aquifer or overlying tills over a range of values observed in field sites near the cities of Akeley, Cromwell, Litchfield, and Olivia, Minnesota.
