Zhenshui Sand Bar and Its Cause in Xiaolangdi Reservoir

摘要：

　　The total original storage capacity of Xiaolangdi reservoir is 12.75 × 109 m3,thereinto,the tributary storage capacity accounts for 41.3% of the total.Zhenshui is the biggest tributary of Xiaolangdi Reservoir,and its original storage capacity is 1.767 × 109m3 and accounts for 33.5% of the tributary.By October 2010,the amount of sediment in Zhenshui reached 0.169,1 × 109 m3,and the sand bar was 7 m in height.The results show that it is influenced by operational mode of reservoir and terrain,and the formation of sand bar at Zhenshui estuary has certain inevitabilities.The sand bar can prevent water and sediment exchange between mainstream and tributary,and the internal storage capacity of tributary is not effectively used.Analyzing sand bar and its cause can supply some technical supports for prevention.
