Simulation of Ground-Water Flow and Delineation of Areas Contributing Recharge within the Mt. Simon-Hinckley Aquifer to Well Fields in the Prairie Island Indian Community, Minnesota

摘要

The purpose of this report is: (1) to describe the development, construction, and application of a groundwater flow model of the Mt. Simon-Hinckley aquifer in the study area to use the flow simulation results for delineation of 10-and 50-year areas within the aquifer that contribute recharge to two community well fields. A calibrated numerical ground-water flow model of the Mt. Simon-Hinckley aquifer combined with a particle-tracking program provided the basis for delineation of the recharge areas. The particle tracking program used hydraulic heads and flow-distribution output from the ground-water flow model and assumed pumping conditions based on recent water-use records from one of the well field (water-use records were not available for the other well field, which was not yet operational).
