2024年黄河上中游重点水库联合排沙效果及河道影响分析
Analysis of the Joint Sediment Discharge Effects of Key Reservoirs in the Upper and Middle Reaches of the Yellow River and Impact on the River Channel in 2024
摘要
Abstract
In September 2024,Yellow River Conservancy Commission carried out a joint sediment discharge operation on key reservoirs in the upper and middle reaches of the Yellow River,including Longyangxia,Liujiaxia and Wanjiashan.The operation lasted for 16 days and achieved good results in sediment discharge and silt reduction.The five reservoirs of Shapotou,Qingtongxia,Haibowan,Wanjiazhai and Longkou discharged a total of 152.61 million tons of sediment,and the total erosion in the reservoir area was 66.92 million tons,with a com-bined sediment discharge ratio of 178.1%.The front sections of the Qingtongxia and Haibowan reservoir dams had been severely scoured,providing favorable boundary conditions for sediment reduction in the future.The Wanjiazhai Reservoir had achieved an annual equilibrium between sediment erosion and deposition,thereby effectively slowing the reservoir's sedimentation rate.The aforementioned analysis demon-strates that utilizing upstream reservoir water storage to implement joint sediment discharge is not only effective but also offers a novel ap-proach for reducing reservoir sedimentation during flat low-water years.关键词
