A wide range of resource managers, policymakers, and scientists require tools to provide information relevant for water resource management and planning. One such tool is the Variable Infiltration Capacity model, which can be used to simulate water flows throughout the Columbia River Basin in the Pacific Northwest. Previously this model used just three numbers as inputs for each day of the simulation: the high and low temperatures and the daily total precipitation. This project investigated several other approaches to providing additional information, three of which consist of different statistical ways of mapping temperature and precipitation onto the mountainous landscape ("downscaling"), and one that uses fine-scale regional climate modeling. Our findings help advance the next generation of climate-hydrology simulations that will provide guidance for studies of climate change impacts on the hydrology of the Pacific Northwest.
