清峪水库年径流分析计算

Analysis and Computation on Annual Runoff of Qingyu Reservoir

清峪水库无水文资料,控制流域年径流量计算采用鄂河乡宁水文站年径流资料面积比法,年径流深等值线法,年降雨等值线及径流系数法,与附近流域年降雨径流关系水文比拟法等四种方法计算。经分析并与实测流量比较,采用与附近流域年降雨径流关系水文比拟法计算成果。

There are not hydrologic data in Qingyu Reservoir.Four methods are adopted to compute annual runoff of controlled basin. They are： 1） area ratio method of annual runoff data obtained from Xiangning Hydrometric Station located on E River,2） contour line method of annual runoff depth,3） method of annual precipitation contour line and runoff coefficient,4） method of hydrologic analogy of relation between annual precipition and annual runoff of neighboring basin. Through analyzing and comparing with measured data,the fourth method is selected.
