A Spatial Model of Snowmelt-Rainfall Runoff Formation of the Mountain River (by the Example of the Upper Kuban River)

L. S. Kuchment, A. N. Gelfan, and V. N. Demidov

A spatial model is proposed of snowmelt-rainfall runoff formation of the mountain river enabling to take account of spatial inhomogeneity of the river catchment and vertical zoning of physiographic and meteorological conditions. The model describes the processes of snow cover formation at various altitudes and snow melting, infiltration into the soils, evaporation, and overland, subsurface and riverbed flows. The verification of the model was carried out from the observational data in the Kuban River basin up to the town of Armavir.
