Hydrogeologic Assessment and Simulation of Stream-Aquifer Relations in the Lower Apalachicola-Chattahoochee-Flint River Basin
Progress and Significant Results, 2002—2003
- Collected new hydrogeologic data defining aquifer and semiconfining-unit thickness and extent, and evaluated results of aquifer-performance tests; incorporated new information into Ground-Water-Site-Inventory database.
- Compiled recent (post-1986) hydrogeologic information on aquifer and semiconfining-unit thickness and extent, hydraulic properties, and pumpage, from GaEPD records.
- Incorporated well coordinates from agricultural wells, obtained by GaEPD using global-positioning-system technology, into local database used for developing model inputs.
- Analyzed agricultural withdrawal data for spatial and temporal relations.
- Evaluated ground-water-level measurements, stream-discharge data, hydrograph-separation methods, and off-stream springflow for October 1999, April 2000, and August 2000 conditions to define ground-water flow to streams.
- Installed five real-time streamgaging stations and upgraded one station for water-quality and acoustic velocity metering.
- Added 12 sites to monitor-well network of hourly groundwater- level recorders and one real-time satellite station.
- Initiated application of USGS transient finite-element model, MODFE, and development of automated input/output
graphical user interface.
