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 water input (gwava-dw_wtin)
This data set represents "water input," the ratio of the total
area of irrigated land to precipitation, in square kilometers
per centimeter, 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.
