MODFLOW grid for simulations used to evaluate the potential effect of Lower Floridan aquifer groundwater pumpage on the Upper Floridan aquifer at Barbour Pointe community in Chatham County, Georgia

A revised regional groundwater-flow model using a modified grid in conjunction with USGS MODFLOW-2000 was developed to the predict the effects of Lower Floridan aquifer (LFA) groundwater pumpage on the Upper Floridan aquifer (UFA) in the Barbour Pointe community, Chatham County, Georgia. The model was modified using hydrogeologic information obtained from field investigations at Barbour Pointe, Berwick Plantation near Berwick, Pooler, Hunter Army Airfield, Rincon, and Fort Stewart.
