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 fresh surface water withdrawal (gwava-dw_swus)
This data set represents the amount of fresh surface water
withdrawal for irrigation, in megaliters per day, 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 …
