Abstract

After the operation of the reservoir, the sediment deposition in the reservoir will raise the bed elevation at the dam site and reduce the reservoir capacity, which will affect the comprehensive benefits of water supply, irrigation and power generation. Taking the Fenghuangshan reservoir in Guangde City, Anhui province as an example, the characteristics of sediment deposition of the Fenghuangshan reservoir was analyzed by using a one-dimensional mathematical model of sediment transport and bed evolution in the reservoir area. Because of the bottom hole, the sediment delivery ratio and out flow sediment concentration gradually increase with the operation time. During the 30 years of operation, the siltation elevation at the dam site increased rapidly, and then the rate of increase began to slow down. In general, the sediment volume into the Fenghuangshan reservoir is not much compared with the reservoir capacity, and the sedimentation is not serious. At the end of 100 years, the reservoir capacity under normal water level and beneficial reservoir capacity are reduced by only 8.79% and 8.24%.
