Developed an integrated MODFLOW-CROPSIM soil-groundwater stream-aquifer interaction model covering the Lower Platte basin in eastern Nebraska. The model is utilized by the Nebraska Department of Natural Resources to conduct stream depletion analysis for groundwater permitting and management purposes. The model domain covers seventy four watershed basins and accounts for transient evaporation, precipitation, runoff, plant uptake, and irrigation to derive aquifer recharge. Aquifer parameterization was accomplished using the Pilot Point methodology, and the coupled model calibrated with the PEST optimization software.
