This $621,463 federal Project Grant award from the U.S. Geological Survey (USGS) under the Assistance to State Water Resources Research Institutes (CFDA 15.805) program aims to improve national-scale estimates of poorly constrained water budget components. The award to Oregon State University (OSU) will leverage precipitation stable isotope data and hydrologic models to diagnose biases in evaporation and transpiration fluxes within advanced operational models. The project will focus on four contrasting watersheds for testing and validation, with expansion to the continental U.S. The expected outcomes include detailed evaluation of model outputs, national-scale estimates of hydrologic flux magnitudes, and isotopically informed diagnostics of water fluxes. Project results will be disseminated through open access publications, datasets, and code repositories to benefit hydrologic modeling end-users such as water availability forecasters, agriculture, and energy production sectors.
