Groundwater Use 

GROWMAS/Satellite ET Program

 A remote sensing model called eeMETRIC that estimates evapotranspiration (ET) from satellite imagery is available to provide an estimate of crop water use as an alternative to volumetric metering. This model originated at the University of Idaho and was implemented by Desert Research Institute (DRI) as part of the OpenET project. SEWD measures the applied surface water delivery data for parcels that received surface water. Through a supply/demand water balance, the surface water use, precipitation data and ET data can be used to estimate the net-to-from-groundwater (NTFGW) on an annual basis at the parcel level.
