Irrigation Water Use map, monthly averages 2009-2020 by watershed

Detailed Description

This model computes the amount of crop irrigation withdrawals each month over the period from 2000 to 2020 for all subwatersheds (12-digit Hydrologic Unit Codes or HUC12s) in the conterminous United States (CONUS).

Crop irrigation withdrawals refer to water removed from a groundwater or surface-water source to produce agricultural crops. In this model, crop irrigation withdrawals are calculated by combining modeled irrigation consumptive use, irrigation efficiencies, and source-water proportions.
