清涧河延川水文站上游溢流挡水坝可供水量分析计算

Available water analysis and calculation of the overflow dam located at Yanchuan Hydrological station in the upstream of Qingjian River

为了获得清涧河上建有的溢流挡水坝处的可供水量,依据清涧河挡水坝下游延川水文站47年径流资料,以延川站作为参证站,采用水文比拟法,推求清涧河挡水坝取水口断面的年径流量,分析计算清涧河生态基流量与取水口下游用水户用水量。以日作为调节计算时段,计算得到清涧河挡水坝取水断面的可供水量,以此作为供给用水户水量的依据与参考。

In order to get data of available water of the overflow dam built in Qingjian River,according to Qingjian River retaining dam downstream hydrological station 47 years runoff data in Yanchuan station as a reference station,using hydrologic assimilation method, Calculating the annual runoff of Qingjian River retaining dam water intake section,analysis and calculation of ecological base flow Qingjian river water intakes downstream water consumption.Taking a day as an adjustment calculation period,calculated available water in intake water section of Qingjian river retaining dam,it provides a basis and reference for water supply consumption.
