Analysis on flood defense measures of Miyun Reservoir under high water level operation
As an important strategic reserve base for water resources in Beijing,Miyun Reservoir also undertakes key flood control tasks.In recent years,the reservoir has been continuously operating at high water levels,facing the practical dilemma of"storage and discharge",and the pressure on flood is constantly increasing.In order to analyze the current flood control capacity of Miyun Reservoir,this study focuses on three aspects:flood monitoring,forecasting and warning,flood regulation,and flood fighting and rescue technology,and analyzes the countermeasures for flood prevention of Miyun Reservoir focusing on engineering and non engineering measures.Analyzed the historical flood characteristics since the construction of Miyun Reservoir,as well as the current situation of forecasting and warning.Focused on the different scenarios of small-and medium-sized floods,flood regulation calculations were carried out.Measures and suggestions were proposed for implementing forecasting and scheduling for small and medium-sized flood.Typical rainfall scenarios in Beijing,Shanxi and Henan provinces were selected for displacement simulation of extreme rainfall processes,and scheduling plans were proposed to provide reference for the reservoir to cope with extreme rainfall.Based on the above analysis,suggestions have been put forward for the construction of a smart system with integrated monitoring,forecasting,and regulating with the forcasting,early warning,drilling and emergency plan(FEDE)functions.The relevant results can provide reference for the optimization of flood regulation and the improvement of flood management technology in Miyun Reservoir.
