Snowmelt runoff modeling in Kaidu basin using the SRM

Snowmelt water plays an important role for social development and ecology construction in and area in northwest China. Snowmelt runoff model (SRM) is particularly suitable to large basins for using satellite snow cover data as input. As a temperature index model, representative temperature is the fundament of precise modeling. But there is often only one weather station in large basins; the estimation of representative temperature is difficult. This paper studies the feasibility of SRM to Kaidu basin in Sinkiang and several attempts are compared to determine the most proper temperature input.
