Modeling the Spatial Distribution of Snow Cover during the Spring Snowmelt

Abstract

The use of GIS technologies for modeling the spatial distribution of snow cover in spring is considered. The authors developed a method for the snowmelt calculation by the example of the Votkinsk Reservoir catchment area. It is proposed to take into account the uneven distribution of snow cover across the catchment depending on the terrain features. The paper estimates how the raster cell size variation affects the displaying the modeling results of the spatial distribution of snow cover.
