潇水流域设计洪水分析
Design Flood Analysis of Xiaoshui River Basin
摘要: 针对潇水流域洪水特性选取干流七个控制站,采用洪峰同倍比放大方法计算单站设计洪水过程线。同时运用同频率地区组成法对潇水流域的流域洪水组合进行分析。研究成果可为潇水流域涔天河水库、双牌水库防洪联合优化调度提供可靠的数据支持,对减少洪涝灾害,避免潇水洪水与湘江干流洪水遭遇,有着重要现实意义。
Abstract:
In response to the flood characteristics of the Xiaoshui River basin, this article selected seven control sta-tions at the main stream and used the peak-to-peak ratio amplification method to calculate the design flood hydrographs. The same frequency region composition method was used to analyze the flood combi-nation in the Xiaoshui River basin. The research results can provide reliable data support for the joint op-timization and operation of flood control in the Centianhe and Shuangpai reservoirs, and have important practical significance in reducing flood disasters and avoiding the encounter of Xiaoshui flood and Xiangjiang main stream flood.
