山东湖东滞洪区模拟郑州“7·20”暴雨洪水研究

Study on Simulating Zhengzhou "7·20" Rainstorm Flood in Hudong Detention Area of Shandong

摘要:

本文采用暴雨移置和洪水模拟的方法，利用二维水动力模型，推演分析南四湖流域遭遇河南郑州市“7·20”特大暴雨时湖东滞洪区内的水位及淹没情况，为湖东滞洪区应急预案编制和汛前演练等工作的开展提供数据支撑和理论分析。

Abstract:

By using the methods of storm displacement and flood simulation, this paper uses a two-dimensional hydrodynamic model to deduce and analyze the water level and inundation situation of the Hudong detention area of Nansi Lake basin, encountered the "7 ·20" torrential rain in Zhengzhou, Henan Province, so as to provide data support and theoretical analysis for the preparation of emergency plans and pre-flood drills in Hudong detention area.
