Groundwater Flow and Water Budget in East Central Florida –USGS, in cooperation with the St. Johns River Water Management District, South Florida Water Management District, and Southwest Florida Water Management District, developed a three dimensional model and water budget of the surficial and Floridan aquifer systems in east-central Florida. The study helps to (1) increase the understanding of water exchanges between the surficial and the Floridan aquifer systems, (2) assess the recharge rates to the surficial aquifer system from infiltration through the unsaturated zone and (3) obtain a simulation tool that could be used by water-resource managers to assess the impact of changes in groundwater withdrawals on spring flows and on the potentiometric surfaces of the hydrogeologic units composing the Floridan aquifer system.

Hydrologic Cycle Components for Counties and Cities in Virginia –USGS, in cooperation with the Virginia Department of Environmental Quality, quantified the components of the hydrologic cycle across the Commonwealth of Virginia. Long-term, mean fluxes were calculated for precipitation, surface runoff, infiltration, total evapotranspiration (ET), riparian ET, recharge, base flow (or groundwater discharge) and net total outflow. Final results for the study are presented as component flux estimates for all counties and independent cities in Virginia and can be used for planning and management of water resources in the face of droughts, changing land-use and best management practices, and other varying conditions.

Water budgets for abandoned underground mines in Pennsylvania –A USGS report, prepared in cooperation with the Pennsylvania Department of Environmental Protection, the Eastern Pennsylvania Coalition for Abandoned Mine Reclamation, and the Dauphin County Conservation District, provides estimates of water budgets and groundwater volumes stored in abandoned underground mines in the Western Middle Anthracite Coalfield, which encompasses an area of 120 square miles in eastern Pennsylvania.
