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...

This model archive makes available the calibrated Soil-Water-Balance (SWB) model used to simulate potential recharge for the Mississippi Alluvial Aquifer for 1915 to 2018. The model was calibrated using monthly values of evapotranspiration and annual values of runoff and recharge for 19 drainage basins selected from within or nearby the Mississippi Alluvial Aquifer system. The calibrated SWB model and its use are described in the associated U.S. Geological Survey Open-File Report 2021-1008. The model was used to create output at two different scales: 1,609-meter and 1,000-meter grid cells. Also included are files used to generate a high-resolution (100-meter) subset of output for an area near Shellmound, Mississippi....

The U.S. Geological Survey (USGS) and the West Virginia Water Gaging Council have proposed an expansion to the existing West Virginia streamgage network. As of December 18, 2018, the USGS operates a network of 149 real-time streamgages in West Virginia. This geospatial dataset provides the approximate locations of 39 proposed streamgages. These streamgages include 31 presently operated by the West Virginia Division of Homeland Security and Emergency Management and 8 new streamgages. These streamgages may be relocated depending on access and stream conditions, and data users who need precise locations of these streamgages may contact the USGS office in Charleston, West Virginia.

As part of a study to analyze the effects of sea-level rise on groundwater resources of Colonial National Historical Park, a monitoring network was established on Historic Jamestown Island, Virginia, to evaluate current levels of and changes in groundwater elevation and water quality. The monitoring network includes 45 wells and piezometers, 3 marsh sites, and 2 surface-water sites distributed across 5 sampling locations on Jamestown Island. Field parameters, including water temperature, specific conductance, pH, and dissolved oxygen, were collected at the marsh and surface-water sites. Field parameters and water levels were collected from the wells and piezometers. Information provided in this data release was...

This geospatial dataset includes one point feature class file and associated FGDC-compliant metadata representing datasets to support development of ecological limit functions for the Cumberland Plateau in northeastern Middle Tennessee and southeastern Kentucky. Knight and others (2012, 2014) developed a methodology of relating fish species richness to changes in hydrologic conditions for sites within the Tennessee River Basin; this dataset applies this methodology to 138 sites within the the Cumberland Plateau. Information contained within this dataset represents values of basin characteristics (see Table II in Knight and others, 2012), estimates of streamflow characteristics (see Table I in Knight and others,...
