Changing Characteristics of the Meltwater Runoff in the Sikeshu River and Their Potential Influence to the River Runoff

The Sikeshu River is the main water resources for the industry and agriculture production and the economy development of Wusu Municipality, and is also a river with frequent flood disaster. In the Sikeshu River basin, owing to short of water resources and the increasing contradictory between water supply and demand, the local economy development is seriously restricted. In this article, taking the Sikeshu River runoff as the main object of study, the change characteristics of monthly runoff and annual runoff are analyzed, and based on the studies of the predecessors, the meltater runoff is estimated. The water resources are very sensitive to the climate change. Analyzing the responses of meltwater runoff to the climatic factors, such as air temperature and precipitation, the changing characteristics of the meltwater runoff in the Sikeshu River and their potential influence to the river runoff are revealed. In the past some years, water cycle has intensified, resulting from of the climate warming and the human
