五星水库是柳河流域铁牛河下游一座中型水库 ,通过对入库水沙特性分析 ,提出水库初期、中期、后期的运行方式和排沙代补及淤积量和使用年限。建议水库上游采用各种措施和管理措施 ,减少入库泥沙 ,提高排沙比 ,以延长水库使用年限 ,使水库发挥最大的效益。 Five-star reservoir is a medium-sized reservoir in the lower reaches of Tieniu River in Liuhe River Basin. Based on the analysis of the characteristics of water and sediment in the reservoir, five-star reservoirs are proposed to run in the initial, middle and later phases of the reservoir, and the sediment replacement, deposition and service life. It is suggested that various measures and management measures should be adopted in the upstream of the reservoir to reduce sediment storage and increase the sediment discharge ratio so as to prolong the service life of the reservoir so as to maximize the reservoir benefits.
