Abstract

Snow is an important fresh-water resource in China especially in west northern China. This paper presents a review of studying on snow cover distribution and snowmelt runoff simulating and forecasting using remote sensing date sets in China. The snow cover mapped derived from different methods and hillshading effect will be discussed in detail. A dominating model-SRM (Snowmelt Runoff Model) model and some statistics models have been used to simulating the discharge in different watersheds. Meanwhile, based on the fact of climatic change, a sample in Heihe Basin in West northern China has been given to prove that the snowmelt runoff regime has relevantly changed in the time and spatial. Also, some viewpoints are given voice to research on snowmelt runoff modeling at the present time and further.
