Synthesizing the Snowmelt Runoff Analysis in the Uono River Basin

Abstract

Snowmelt runoff analysis consisting of three submodels is developed. These submodels are the model for estimation of basin-wide snow water equivalent using snow covered area, the model for estimation of basin-wide snowmelt rate and the runoff model. In each model we use the information on snow covered area derived from LANDSAT MSS data.The meteorological data from AMeDAS is used also. We apply these models to the Uono River Basin in NIIGATA, during the snowmelt season in 1979, 1981, 1982. The results of model applications are in good agreement with observed data.
