Water-level measurements of wells were taken in the Upper Floridan aquifer between the dates of May 2 and June 23, 2010. A GIS shapefile of these water-level measurements was constructed and released as part of a prior USGS publication (Kinnaman and Dixon, 2011). This ArcGIS layer was updated in August 2014 to include salinity-based density corrections to water levels in those areas of south Florida where water in the subject aquifer is not fresh. The density corrections to water levels result in the portrayal of the “equivalent freshwater head” values in brackish and saline areas of the Upper Floridan aquifer where water quality data were available.

A previously-developed groundwater model of the Suwannee River Basin was modified and calibrated to represent transient conditions. A simulation of recent conditions was developed for the 372-month period 1970-2000, and was compared with a simulation of future conditions for a similar-length period 2039-2069, which uses downscaled GCM (Global Climate Model) data. The MODFLOW groundwater-simulation code was used in both of these simulations, and two different MODFLOW boundary condition “packages” (River and Streamflow Routing Packages) were used to represent interactions between surface-water and groundwater features. The parameters for the simulation of future conditions were developed from dynamically downscaled...
This layer shows the potentiometric surface contours of the Upper Floridan Aquifer in Florida and parts of Georgia, South Carolina, and Alabama in May 2010. Contours were manually contoured from well elevation data collected in May-June 2010. This layer was updated in August 2014 to include south Florida by calculating the equivalant freshwater head where water quality data was available.

This Data Release has 18 different groundwater flow simulation applications for the Woodville Karst Plain area near Tallahassee Florida with three variations of distributed parameter model approach. The site model files provided include both calibrated and uncalibrated simulations of various steady-state and transient hydrologic conditions. Simulations were accomplished with equivalent porous media models that allow laminar flow only (MODFLOW) or laminar and non-laminar flow in a model layer (MODFLOW-CFP mode 2) and hybrid model simulations (MODFLOW-CFP mode 1 one-dimensional pipe network linked to equivalent porous media model). The test examples of the application of equivalent porous media model (the sponge)...
