Heuristic MODFLOW models used to evaluate the effects of pumping groundwater from confined aquifers overlain by till confining units
December 23, 2020
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.

Confined (or buried) aquifers of glacial origin overlain by till confining units provide drinking water to hundreds of thousands of Minnesota residents. The sustainability of these groundwater resources is not well understood because hydraulic properties of till that control vertical groundwater fluxes (leakage) to underlying aquifers are largely unknown.
