摘要

A groundwater-flow model developed by the U.S. Geological Survey was used to evaluate the effects of agricultural groundwater pumping on the groundwater-flow system of the Upper Floridan aquifer in the lower Apalachicola-Chattahoochee-Flint River basin in southwest Georgia and adjacent parts of Alabama and Florida. To quantify the relative effects of groundwater pumping at different locations within the model area, pumping was applied at numerous locations in successive simulations. By comparing each result to a base simulation, changes in groundwater flow at model boundaries-streams, lakes, and regional model boundaries-were computed and stored in a response matrix for each location. Queries to the response matrix were designed to determine the sensitivity of various boundary flows to agricultural pumping. Contour plots of results illustrate the spatial variation of the sensitivity to pumping across the model area.
