Research on overflow forecasting method of Chengbei Reservoir in Dinghai District,Zhoushan City based on two important typhoon processes in 2021
Based on the two important typhoon processes affecting Zhoushan in 2021,using the surface rainfall,the rainfall of Dinghai National Basic Meteorological Station and the rainfall of automatic meteorological station around Chengbei Reservoir as reservoir rainfall values,this paper analyzes the water storage capacity and overeflow capacity of Chengbei Reservoir.It is concluded that the two important typhoon processes affecting Zhoushan in 2021 have high research value.Taking the precipitation of Dinghai National Basic Meteorological Station as the main reference data has obvious practical application advantages.Every 1 mm precipitation can cause about 5 000 m3 of reservoir flood overflow/storage in Chengbei Reservoir.The prediction equations obtained from the study can provide a reference for the predicting factors such as overflow time and overflow volume of Chengbei Reservoir in Dinghai District.
