Variable infiltration capacity cold land process model updates
The Variable Infiltration Capacity (VIC) macroscale hydrologic model is distinguished from other Soil–Vegetation– Atmosphere Transfer schemes (SVATS) by its focus on runoff processes. These are represented via the variable infiltration curve, a parameterization of the effects of subgrid variability in soil moisture holding capacity, from which the model takes its name, and a representation of n...
متن کاملFractional snow-covered area parameterization over complex topography
Fractional snow-covered area (SCA) is a key parameter in large-scale hydrological, meteorological and regional climate models. Since SCA affects albedos and surface energy balance fluxes, it is especially of interest over mountainous terrain where generally a reduced SCA is observed in large grid cells. Temporal and spatial snow distributions are, however, difficult to measure over complex topo...
متن کاملDetermining the Snow Coefficient in order to simulate the snow melting in the Shemshak Watershed Using the WetSpa Model
In mountainous regions, snow forms a part of the precipitation. Therefore, snow melting is an important process in hydrology and hydraulic in these areas that its role should be considered independently in runoff generation. The Shemshak watershed basin located in Tehran province was selected as the study area of this research to examine the efficiency of the WetSpa hydrologic model to simulate...

Given the importance of snow, it seems necessary to predict its resultant runoff for optimized usage. In addition, due to snowbound regions cloudiness in winter season, the notice of snow cover area (SCA) using satellite images is difficult. Hence, to help better water resources managing in mountainous areas using supplementary methods for simulating the SCA is necessary. As a case study, Horo-...
متن کاملExtension of the Representative Elementary Watershed approach for cold regions: constitutive relationships and an application
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The representative elementary watershed (REW) approach proposed by Reggiani et al. (1998, 1999) represents an attempt to develop a scale adaptable modeling framework for the hydrological research community. Tian et al. (2006a) extended the...
