Soil-Water-Balance model data sets for Fauquier County, Virginia, 1996 - 2015

A Soil-Water-Balance (SWB) model was developed to estimate annual recharge and evapotranspiration (ET) for Fauquier County, Virginia, for the period 1996 through 2015. The model was developed as part of a study to assess groundwater availability in the fractured-rock aquifers underlying Fauquier County. The model is documented in the associated report, U.S. Geological Survey (USGS) Scientific Investigations Report 2019-5056. The model was calibrated by comparing annual base-flow estimates from the hydrograph separation technique PART to annual recharge estimates from the SWB model for available years of streamflow record at two sites (01643700 and 01656000) within the model area. Selected SWB model parameters were adjusted to improve model fit. The calibration procedure is documented in USGS Scientific Investigations Report 2019-5056, and calibration results are included in the calibration.xlsx spreadsheet included in this archive.
