双峰水库水资源可利用量计算分析

Calculation and analysis of available water resources in Shuangfeng reservoir

双峰水库位于山西省榆社县,是一座以防洪、生活供水和灌溉为主要任务的中型水库。本文通过收集坝址所在浊漳河北源43年(1974—2016年)的实测径流系列资料,对年径流量进行频率分析,在此基础上进行了径流调节计算,得出双峰水库水资源可开发利用量。计算结果表明能够进一步提高双峰水库水资源开发利用程度,对于充分利用双峰水库水资源、提高兴利效益具有一定的现实意义。

Shuangfeng Reservoir,located in Yushe County in Shanxi Province,is a medium-sized reservoir with flood control,domestic water supply and irrigation as its main tasks.In this paper,the frequency of annual runoff is analyzed by collecting the measured runoff series data of 43 years(1974—2016)from the source of Zhuozhang River,where the dam site is located.On this basis,the runoff regulation calculation is carried out,and the exploitable amount of water resources in Shuangfeng Reservoir is obtained.The calculation results show that the degree of exploitation and utilization of water resources in Shuangfeng Reservoir can be further improved,which has certain practical significance for fully utilizing water resources in Shuangfeng Reservoir and improving profit-making benefits.
