Analysis of Impacting Factors on Runoff and Sediment Transport of Flood Event in Gushanchuan Basin
摘要
Abstract
The turning point of water and sand of natural period and human activity impacting period in Gushanchuan basin is the year 1979, which was analyzed by method of orderly clustering, MWP test and Mann⁃Kendall method. The model was established by using the data before 1979, and the impacting factors on runoff and sediment transport of flood event after 1979 were analyzed. The results show that during the period of 1980 to 2010, rainfall change and human activity occupies 65.7% and 34.3% respectively on runoff reduction of flood event, and occupies 72.9% and 27.1% respectively on sediment transport reduction.关键词
