Abstract

Focus on the characteristics of runoff yield and flow,considering the influence of terrain,radialization,wind,vegetation distribution and frozen earth on snowmelt,the daily runoff of montane river which is mixed replenishment of ice and snowmelt has been studied based on the theory of conservation of energy with SWAT model.Base on the snow pack information of RS and GIS,and 21 years of the actual metrical data about weather and the runoff from 1980 to 2000 in the Manasi valley,SWAT model for snowmelt river has been established.The daily runoff of Kensiwate hydrological station in the mountain pass of the Manasi watershed was simulated.The results showed that RE of the simulation was 17%,Nash Sutcliffe was 0.73,the simulation was reasonable,and it would supply an effective method for studying the ice and snowmelt rivers in future.
