1013 W in the soil–plant–atmo-sphere system are important at the local, regional, and global scales. Direct measurement of these fl uxes is generally limited to a few locations and to relatively short periods. Many computer simulation models have been developed to study the spatial and temporal patterns in water and energy fl uxes. Th e models facilitate(More)
Snowmelt in mountainous areas is an important contributor to river water fl ows in the western United States. We developed a distributed model that calculates solar radia on, canopy energy balance, surface energy balance, snow pack dynamics, soil water fl ow, snow–soil–bedrock heat exchange, soil water freezing, and lateral surface and subsurface water fl(More)
321 H based on one-dimensional simulations of the vadose zone are routinely used to predict or study fl uxes of moisture, solutes, and energy at fi eld and watershed scales. For the results of these models to be useful, suf-fi ciently accurate soil hydraulic property inputs, namely the soil moisture retention and hydraulic conductivity curves, θ(h) and(More)
The distributed Soil Water Assessment Tool (SWAT) hydrologic model was applied to a research watershed, the Dry Creek Experimental Watershed, near Boise Idaho to investigate its water balance components both temporally and spatially. Calibrating and validating SWAT is necessary to enable our understanding of the water balance components in this semiarid(More)
Many catchment hydrologic and ecologic processes are impacted by the storage capacity of soil water, which is dictated by the profile thickness and water retention properties of soil. Soil water retention properties are primarily controlled by soil texture, which in turn varies spatially in response to microclimate-induced differences in insolation, wetness(More)
In the western United States, the mountain snowpack is an important natural reservoir that extends spring and summer water delivery to downstream users and ecosystems. The importance of winter snow accumulation to upland ecosystems is not as clearly defined. This study investigates the relative contribution of winter precipitation to upland spring and(More)
