汤河水库上游无国家或省级设立的水文站,缺乏实测流量资料。本文利用鹤壁雨量站45a最大24h雨量资料进行频率计算,采用设计洪峰流量经验公式法和小汇水面积设计洪峰流量法两种计算方法进行比较,复核汤河水库千年一遇洪水最大入库洪峰流量,以对汤河水库防汛和科学调度进行有益探讨。
There is no national or provincial hydrological station in the upper reaches of Tanghe Reservoir, lacking the measured flow data. In this paper, the maximum 24-h rainfall data of Hebi rainfall station were used to calculate the frequency. The formula of peak flow rate formula and the method of small catchment area design flood peak flow method were used to compare and calculate the peak flood discharge volume , In order to conduct a good discussion of flood control and scientific scheduling of the Tanghe Reservoir.
