A technique has been suggested for simulation of snowmelt runoff on the basis of physically based model of runoff
generation, available ground-based observations and satellite-derived data on land surface. Simulations have been
carried out for two regions including the basins of Vyatka and Don Rivers. It has been shown that the satellite data,
in spite of their errors, can be important adjunct to the ground-based observations for simulation of spatial patterns
of runoff generation. Using of the physically based models of runoff generation allows one to reduce errors of satellite
data on snow cover and provides time-and-spatial continuity of snow monitoring.
