Soil-Water Balance model datasets used to estimate groundwater recharge in Florida and parts of Georgia, Alabama, and South Carolina, 1895-2010
Description
A soil-water balance model (SWB) was developed to estimate potential recharge and
irrigation water demand from the groundwater flow system in Florida and parts of Georgia,
Alabama, and South Carolina for the period 1895 through 2010. This SWB model executable
code detailed in the report SWB—A Modified Thornthwaite-Mather Soil-Water-Balance Code
for Estimating Groundwater Recharge; Chapter 31 of Section A, Groundwater, of Book 6,
Modeling Techniques By S.M. Westenbroek, V.A. Kelson,W.R. Dripps,R.J. Hunt, and
K.R. Bradbury (https://pubs.usgs.gov/tm/tm6-a31/) The SWB model was not calibrated;
however, various water budget components from the model output compared reasonably
well with other estimates including irrigation pumpage quantities reported by the States
of Florida and Georgia. Irrigation water demand for 6 crop types (citrus, field crops, hay,
sod, sugar cane, and vegetables) were calculated for the period 1950-2010. This USGS
data release contains all of the input and output files except climate data for the simulations
described in this data release. Due to size limitations climate data used in the production
of this model are not included in this archive, URLs to locate the climate data are included.
