Snowmelt runoff analytical method consisting of three submodels is developed. These submodels are the model for estimation of basin-wide snow water equivalent as a function of snow covered area, the model for estimation of basin-wide snowmelt rate, and the runoff model. In each model the information on snow covered area derived from LANDSAT TM data is used. These models are applied to the Uono River Basin during the snowmelt season in 1989, 1993. The calculation are in good agreement with the observed data.
