Spatially distributed snow modeling and hydrograph simulation -- Continuing Boise River application

Progress is reported for an ongoing project to apply a snow model coupled with a hydrograph simulation model, both spatially distributed, to a river basin of extensively managed water resources. Snowpack, precipitation, and temperature have been monitored in the Boise River Basin of Idaho for years by both the Natural Resources Conservation Service (NRCS) and the Bureau of Reclamation. In this latest phase of the project, additional sensors have been installed at three NRCS SNOTEL sites, which are expected to improve the snowpack simulation. How these new data are applied in the model will be discussed, as well as the direction of further work.
