摘要
文章通过流域控制性水文站和水利工程的观测资料,分析出天然降雨量、洪水来水量,统计了主要干支控制性水位值,结合现有历史洪水资料和工程设计成果,分析了巢湖流域2020年洪水特征和重现期。综合流域降雨量、长江外河水位因素进行分析,得出今年洪水的综合重现期。
Through the observation data of watershed control hydration station and water conservancy project,the natural rainfall and flood water quantity are analyzed,the main dry branch control water level value is counted,and the flood characteristics and reproduction period of Chaohu basin in 2020 are analyzed according to the existing historical flood data and engineering design results.The analysis of rainfall in the comprehensive basin and the river level factors outside the Yangtze River leads to the comprehensive re-emergence period of this year’s flood.
