在已建水库上游修建新水库时兴利库容的确定

Determining of Beneficial Capacity When Building A New Reservoir on The Upstream of Built Reservoir

结合贵州省桐梓县将在天门河已建的天门河水库的上游拟建新桥水库的实际,介绍通过两水库联合调节来确定上游拟建水库兴利库容的计算方法,即根据区域来水情况和用水需求,对上下两水库反复多次进行联合调节计算来确定上游拟建水库的兴利库容。

Combining with practice of planning to build Xingqiao Reservoir on the upstream of built Tianmenhe Reservoir on the Tianmenhe River,the writer introduces the calculation method of determining beneficial capacity of the new reservoir on the upstream by joint regulation of the two reservoirs.This is that the beneficial capacity of the new reservoir was determined through calculating joint regulation of the two up-down reservoirs repeatedly many times,on the base of incoming flow on the basin and water demand.
