Fauquier County Groundwater Recharge

A Soil-Water-Balance (SWB) model (Westenbroek and others, 2010) was developed to estimate the mean annual water budget for the period 1996 through 2015 and the annual water budget for a drought-year in 2001. This application allows the display and...

Drought Streamflow Probabilities in Northeast Region

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Northeast region streams. Winter streamflows are used to estimate the chance of hydrologic drought during summer months. Hydrologic drought streamflow probabilities for July, August, and September are provided 5 to 11 months in advance. This application allows the display and query of drought...

Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2018

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) stations for the period 1985 through 2018. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS...

Shenandoah River Accumulated Wastewater Ratio (Version 2.0)

Incedental wastewater reuse from streams that receive discharges from Wastewater Treatment Facilities (WWTF) has the potential to be a significant contributor of Endocrine Disrupting Chemicals. An ArcGIS model of WWTFs, NHDPlus Version 2 stream networks (USGS and EPA 2012), and gage stations across the Shenandoah River watershed was created to calculate accumulated wastewater in percent of...
