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
July 20, 2017
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.

Simulated effects of Lower Floridan aquifer pumping on the Upper Floridan aquifer at Barbour Pointe, Chatham County, Georgia
Steady-state simulations using a revised regional groundwater-flow model based on MODFLOW were run to assess the potential long-term effects on the Upper Floridan aquifer (UFA) of pumping the Lower Floridan aquifer (LFA) at well 36Q398, located at Barbour Pointe in coastal Georgia near Savannah. Simulated pumping of well 36Q398 at a rate of 750 gallons per minute (gal/min; or 1.08 million gallons
