“It is both complex and challenging to model the hydrologic water balance in mountain watersheds due to the lack of observations from high elevations at a resolution that is critical to accurately understand and partition precipitation into streamflow, evapotranspiration, drainage and ground water recharge. This study will involve hydrological modeling of two basins namely the Treasure Valley and Rathdrum Prairie and Palouse Basin located in different parts of Idaho which are also the priority watersheds under the Comprehensive Aquifer Management Plan of the Idaho Department of Water Resources. Using the spatially distributed watershed model, Soil Water Assessment Tool (SWAT), we plan to quantify current and future water availability under climate change conditions by providing GIS information including landuse, vegetation, soil and weather conditions at a high resolution to the model. SWAT-predicted streamflow and ET at some selected sites will be validated using the available data. The insights gained from this project will directly benefit in quantifying the spatial distribution and heterogeneity in ET, streamflow and groundwater over a large area on a continuous time scale.”
