Vulnerability of shallow ground water and drinking-water wells to nitrate in the United States: Model of predicted nitrate concentration in U.S. ground water used for drinking (simulation depth 50 meters) -- Input data set for Hortonian overland flow (gwava-dw_hor)
This data set represents infiltration excess overland flow
estimated by TOPMODEL, in percent of streamflow, in the
conterminous United States.
The data set was used as an input data layer for a national
model to predict nitrate concentration in ground water used for
drinking.
Nolan and Hitt (2006) developed two …
