Summary

As part of the National Water Census program in the Apalachicola-Chattahoochee-Flint (ACF) River Basin, the U.S. Geological Survey evaluated the groundwater budget of the lower ACF, with particular emphasis on recharge, characterizing the spatial and temporal relation between surface water and groundwater, and groundwater pumping. To evaluate the hydrologic budget of the lower ACF River Basin, a groundwater-flow model, constructed using MODFLOW-2005, was developed for the Upper Floridan aquifer and overlying semiconfining unit for 2008–12. Model input included temporally and spatially variable specified recharge, estimated using a preliminary version of a Precipitation-Runoff Modeling System (PRMS) model for the ACF River Basin, and [...]

Purpose

The purpose of this report is to evaluate the components of the groundwater budget of the lower ACF River Basin for 2008–12. Particular emphasis was placed on characterizing the spatial and temporal relation between perennial streams, intermittent streams, and wetland discharges and changes in groundwater storage, and recharge and groundwater pumping. This evaluation incorporated a process-based estimation of recharge and groundwater pumping distribution based on data from agricultural metering, field reconnaissance, crop distribution, and spatial analysis. Information gained on groundwater discharge to streams can be used to inform a more accurate accounting of streamflow throughout the ACF River Basin (LaFontaine and others, 2017). The evaluation presented in this report is one element of an overall evaluation of freshwater availability in the ACF River Basin. The development of the model input and output files included in this data release are documented in U.S. Geological Survey Scientific Investigations Report 2017-5141 (https://doi.org/10.3133/sir20175141).
