On the noon of July 31st, Li Guoying, Deputy Commander in Chief of the National Flood Control Administration and Minister of Water Resources, urgently presided over a meeting of the Chamber of Commerce to conduct a rolling analysis and assessment of the development trend of rainfall, water and flood conditions in the Haihe River Basin, and to arrange and deploy flood prevention and control work in the Haihe River Basin.
The meeting pointed out that firstly, based on the current situation of numbered floods in the Ziya River, Yongding River, and Daqing River, timely release of information on major floods in the Haihe River Basin. At the same time, adjust the response level accordingly according to the real-time situation of floods in the basin, and implement corresponding response measures. Secondly, we must closely monitor the key information of key areas, and all measures must serve to defend against large-scale floods in the watershed. We need to monitor real-time changes in floods online and adjust flood prevention measures in a timely manner based on the monitoring results. The fourth is to accurately forecast, monitor, and release flood information, especially to proactively and accurately release information on defense deployment, flood storage and detention area utilization, personnel transfer, and project scheduling, and inform the public in advance. We must establish our own station, strengthen the transmission and prediction of river floods, and release flood forecast information to the next station in advance. Six, we must implement relevant defense measures before the flood arrives, especially for those who need to transfer personnel within the flood storage and detention area. Local governments must ensure that personnel must be evacuated as soon as possible, all should be evacuated, and early as possible to ensure their safety.
