Snow-17 Model (Developed by Anderson for operational use, still used by most River Forecasting Centers in the West. Considers that any type of measurements in the mountains are generally hard to come by.) Thermal Quality and Cold Content Utah Energy Balance Model (Designed by Tarboten and Luce to be physically based but distributed across the landscape. Used more by researchers than for operations.) Emmisivity of snow Specific Heat Latent Heat Density of snow Liquid Holding Capacity Snow Saturated hydraulic conductivity Thermal Conductivity DHSVM (Designed for research use in small basins, for hydrologic applications = primarily interested in water budget at the basin outlet.) Snow reflection Coefficient Snow Water Equivalent Specific Heat of the ice Density of snow Latent heat of ice Variable Velocity Model of water propagation through a snowpack (Designed for research use to understand diurnal cycle timing of melt through a snowpack.) Snow porosity Snow density Intrinsic Permeability Model snowmelt at an hourly basis above a lysimeter Snow temperature Volume of lysimeter Temperature data Precipitation data Specific Heat Latent Heat 2 Model hourly snowmelt in a small (1 km ) alpine watershed DEM of the basin Precipitation, T max and T min Snow temperature Snow density Model daily snowmelt across a large area: Elevation data at different points. Using GIS this information can be created for each grid cell. Fraction of the grid where precipitation occurs. Forcing data (Precipitation, Tmax, Tmin, Wind Speed) Snow Albedo Latitude and Longitude Land use data (Type of vegetation and canopy cover) Latent heat, Specific heat
