Flood control and emergency response cannot be relaxed at all. Monitoring | Floods | Flood control
Since the beginning of the flood season, extreme heavy rainfall has occurred frequently in China, bringing considerable pressure to flood prevention. According to a consultation with the Ministry of Water Resources, the downstream flood discharge in the Haihe River Basin is facing a severe test. The heavy rainfall process in the Songhua River Basin has not yet ended, and Typhoon No. 6 "Kanu" may still have an impact on China. The flood control situation remains severe.
Flood prevention comes first. The more critical the moment is, the more responsibility each region and department must tighten, put in enough effort in the word "prevention", and tirelessly focus on the defense work in key areas and parts.
At present, the flood control in the Haihe River Basin is undergoing a flood evolution process. It is necessary to fully consider the uncertainty of upstream water inflow, and strengthen and elevate weak embankment sections and key embankments with quality and quantity assurance before the subsequent flood peak arrives, ensuring that everything is safe and sound. We need to strengthen embankments and engineering inspections and defenses, implement 24-hour uninterrupted patrols and inspections on rivers, flood control embankments, etc., and closely monitor the risks during the flood retreat period. For embankments and projects in danger, while intensifying rescue efforts, a second line of defense should also be constructed simultaneously.
The flood storage and detention area is a key project for preventing major floods in the basin and ensuring flood control safety in the basin. Faced with the extreme heavy rainfall this year, the relevant water conservancy departments should fully consider the randomness of the occurrence of major floods in the basin, continuously strengthen the four measures of forecasting, warning, rehearsal, and contingency plan, closely monitor the rainfall and water situation, carry out flood rehearsals in a timely manner, scientifically formulate and update the plan for the use of flood storage and detention areas, and use it in a timely manner according to the flood situation in accordance with the law to ensure that the flood storage and detention areas can play a key role at critical moments. For embankments in flood storage and safety zones that have been activated, it is necessary to strengthen defense, increase monitoring and forecasting of flood evolution within the zone, and notify downstream in advance to evacuate affected personnel.
In the process of flood prevention, the difficulty of preventing mountain flood disasters is the greatest. Generally speaking, flash floods cannot be defended by engineering scheduling. The main defense method is for local governments, villages, and groups to issue early warning information and transfer personnel in advance. At present, the key period of flood control overlaps with the summer season. Everyone should enhance their awareness of prevention, pay close attention to the forecast and warning information, and reduce unnecessary travel in rainstorm and flood weather.
Flood prevention and rescue are urgent and urgent. At present, we are still in the critical period of flood prevention with "seven down and eight up". All levels and departments should adhere to the principle of putting people first and life first, always tighten the string of preventing safety risks, seize the time window, focus on the actual needs of basin flood control and reservoir scheduling, accelerate the construction of meteorological satellites, rain radars, rainfall stations, and hydrological stations to form the "three lines of defense" for rainfall monitoring and forecasting, further extend the flood prediction period, and improve the accuracy of flood forecasting. We must scientifically implement flood control scheduling in water engineering, fully utilize reservoir flood control to reduce peak and staggered flow, and promptly carry out measures such as embankment reinforcement and smooth passage of flood channels to ensure the safety of people's lives and property.
