Abstract

This paper examines the detailed spatial and temporal variations of the suspended sediment deposition (SSD) based on the annual suspended sediment load at 5 gaging stations located in the alluvial reach between the Qingtongxia station and the Toudaoguai station of the upper Yellow River in 1952-2007. The mean annual SSDs in 4 sub-reaches (Qingtongxia-Shizuishan, Shizuishan-Bayangaole, Bayangaole-Sanhuhekou, and Sanhuhekou-Toudaoguai) were calculated and analyzed for different periods. Results suggested that SSD was mainly accumulated in 1952-1959 before major reservoirs were constructed and in 1986-2007 after 3 major reservoirs (Qingtongxia, Liujiaxia and Longyangxia) were constructed in the main stream. During 1960-1985, all sub-reaches except the Shizuishan-Bayangaole sub-reach experienced channel erosion. Although climate change may play some roles, the changes in SSD were mainly influenced by human activities. Water and soil conservation and reservoir operations are the main factors
