Watershed Modeling
Watershed Modeling: detailed integrated representation of watershed processes. Includes two layer canopy model for evapotranspiration, energy balance for snow accumulation and melt, a two-layer rooting zone model and a saturated subsurface flow model. The landscape is divided into grid cells on Digital Elevation Model data nodes, used to model absorbed radiation, precipitation, air temperature, and down-slope water movement. When linked to a regional climate model, it can generate snow pack, soil moisture and stream flow information that can be used to manage water resources. (environment)
