Simulation inversion and analysis of"23.7"flood in Zhuozhou City of Hebei Province
The"23.7"flood has created a significant impact and caused heavy losses in Zhuozhou,Hebei Prov-ince.In order to analyze the causes and provide reference ideas for recovery and reconstruction after disaster,as well as future flood control,a two-dimensional flood numerical model was established for the relevant areas of Zhuozhou City.The"23.7"flood in Zhuozhou City was simulated and inverted,and the impact of inundation was compared and analyzed.The results show that,except for the flood magnitude caused by extreme rainstorm,the special geographical location of Zhuozhou City,the weak flood control works and the large increase of construction land in the flood storage and detention area are the main reasons for the great impact and heavy losses of this flood.In the future,the flood control and management of Zhuozhou City,as well as the land development and construc-tion within the flood storage and detention area,should not only refer to the development experience in relevant re-gions,but also strengthen the construction of flood control works,improve the flood defense system,strengthen the construction and management of flood storage and detention areas,strengthen flood risk analysis and real-time forecasting and warning,and enhance the public's awareness of flood risk prevention.
