Title: Development of a cross-sectional ground-water flow model for the coastal plain aquifers near the Savannah River Site, Georgia and South Carolina

Abstract

A two-dimensional cross-sectional model is being developed to simulate ground-water flow in the Upper Floridan, Lower Floridan, Dublin, and Midville aquifers near the Department of Energy, Savannah River Site (SRS), South Carolina and Georgia. The objective is to evaluate the relation of the Savannah River to the ground-water flow system under present and hypothetical conditions. The US Geological Survey Modular Finite Element model (MODFE) will be applied to simulate steady-state flow in an isotropic, heterogeneous medium. Flow nets were drawn using representative potentiometric surfaces to locate a probably path that ground water would take in the multiaquifer flow system. A corridor with a set of coincident flow lines was delineated for all aquifers, except the Midville, where a minor oblique flow component exists. The cross-section is located along a representative flow line in the middle of the flow-path corridor. The line of section crosses the Savannah River and is 11.6 miles long in South Carolina and 5.7 miles long in Georgia. The hydrogeologic framework for the model is based on borehole data collected from wells near the line of section. Boundary conditions to be simulated in the model are: a specified head boundary at the top of the cross sectionmore » (water table), a no-flow boundary at the bottom (basement rocks), a specified head at the eastern side in South Carolina, and a head-dependent flux boundary at the western side in Georgia. The model will be calibrated to a period of time during 1980-1990 during which the system is thought to have been in equilibrium, and verified against another set of hydrologic conditions.« less
