Technical Abstract: The development and ablation of the seasonal snowcover are simulated over the Boise River basin in Idaho, using the topographically distributed energy balance snowmelt model ISNOBAL. The model was driven from a combination of measured and modeled climate data, collected at six SNOTEL sites within, and two just outside the basin. Augmented SNOTEL instrumentation, including snow depth, humidity, wind, soil temperature and moisture, and solar and thermal radiation was available from four of the sites. Vegetation canopy height, density, and structure over the basin were derived from US Forest Service LANDSAT-based vegetation classification maps. Radiation and topographic shading were simulated by first calculating clear-sky, above-canopy radiation.
