The snowmelt runoff model (SRM) has been widely used in simulation and forecast of streamflow in snow-dominated mountainous basins around the world.This paper presents an overall review of worldwide applications of SRM in mountainous watersheds,particularly in data-sparse watersheds of northwestern China.Issues related to proper selection of input climate variables and parameters,and determination of the snow cover area (SCA) using remote sensing data in snowmelt runoff modeling are discussed through extensive review of literature.Preliminary applications of SRM in northwestern China have shown that the model accuracies are relatively acceptable although most of the watersheds lack measured hydro-meteorological data.Future research could explore the feasibility of modeling snowmelt runoff in data-sparse mountainous watersheds in northwestern China by utilizing snow and glacier cover remote sensing data,geographic information system (GIS) tools,field measurements,and innovative ways of model parameterization.
