Résumé
Water supply in many semiarid regions is derived from mountain precipitation, which varies in depth and phase with elevation. Predicting water yield from mountainous regions depends on the spatial and temporal distributions of the source area precipitation and energy balance, which control both snowmelt and evapotranspiration. The Simultaneous Heat and Water (SHAW) model was used to simulate the response of the water balance components to tropical weather to two soil types. The SHAW model was applied to three years of weather, soil moisture, and temperature data at two elevations (1610.5 m and 1142.4 m) in Dry Creek watershed near Boise, Idaho to determine the annual variability in elevational controls on water yield. In particular, we were interested in improving the ability to better predict the water yield for low snow-pack conditions. (Abstract shortened by UMI.)
