At present, the Yangtze River and the Yellow River respectively have the No. 5 flood of 2020, and the main stream of the Huai River has receded below the warning water level. The Shigu River section of the Jinsha River in the upper reaches of the Yangtze River, Zhutuo to Cuntan in the upper reaches of the Yangtze River, Jianli to Lianhuatang River in the middle and lower reaches of the Yangtze River, Minjiang, Tuojiang and Jialing Rivers in Sichuan, Fujiang in Chongqing, Chaohu in Anhui, and Lanzhou and Tongguan in the middle of the upper reaches of the Yellow River 109 rivers such as the Weihe River in Shaanxi and the Keluo River in Heilongjiang have exceeded the warning level. Among them, 39 rivers and lakes including the Cuntan section of the upper reaches of the Yangtze River and the middle and lower reaches of the Minjiang River, Tuojiang River, Fujiang River, the upper reaches of the Jialing River and the tributary Bailong River have exceeded the protection level. Ten rivers, including the main stream and tributary Qingyi River, the Bailong River and its tributary Baishui River in the upper reaches of the Jialing River in Gansu, and the Binlang River, a tributary of the Daying River in Yunnan, are beyond history. At 16:00 on the 18th, the water level from Zhutuo to Cuntan in the upper reaches of the Yangtze River, from Jianli to Lianhuatang in the middle reaches of the Yangtze River, and Dongting Lake exceeded the warning level by 0.06 to 5.90 meters, of which the Cuntan station exceeded the limit by 2.90 meters.
According to the consultation analysis, it is expected that from August 19 to 21, due to the combined effects of typhoon "Hygos" and warm and cold air, parts of southern South China, southwestern and northeastern China, southeastern northwestern China, southern eastern North China, and southeastern northeast China will be affected. There was heavy rain. Affected by this, the upper reaches of the Yangtze River, the upper reaches of the Han River, the middle reaches of the Yellow River, the upper reaches of the Zhanghe River and the Luan River in the Haihe River Basin, the Songhua River, the Liaohe River, the Hunhe River, and the Taizi River in the Songliao River Basin, the Yujiang River, a tributary of the Xijiang River and the coastal rivers of southern Guangxi in western Guangdong, and the rivers in the southwest Rivers such as Daying River and Ruili River will experience significant flooding. Among them, the Zhutuo River section of the Yangtze River will be over-protected, and the Cuntan River section and the Minjiang and Tuojiang Rivers will maintain the over-protection; the Lanzhou section of the upper Yellow River will maintain a large flow, and the middle reaches of the mainstream Tongguan section And the lower Weihe River maintains over-alarm; some rivers in the rainstorm area may have large floods.
The meeting emphasized that the No. 5 flood occurred in the upper reaches of the Yangtze River and the middle reaches of the Yellow River respectively, especially the flood peaks in the upper reaches of the Yangtze River were large. Some areas in the southwest, south, north, and northeast were affected by typhoons or cold and warm air. Severe, it is necessary to implement key tasks such as river flood prevention, reservoir safety during floods, and mountain torrent disaster prevention.
The first is to scientifically implement the dispatch of reservoir groups to deal with floods in the upper reaches of the Yangtze River. It is necessary to intensively forecast forecasts, conduct rolling consultations and analysis, make overall consideration of the upstream and downstream flood control situation, the impact of reservoir inundation, etc., continuously optimize and adjust the dispatch of key reservoirs such as the Three Gorges, and strive to reduce the risk of inundation of the Three Gorges reservoir; scientifically dispatch the upper reaches of the Yangtze River to intercept floods and cut peaks , To reduce the pressure on flood control in the Three Gorges reservoir area.
The second is to do a good job of responding to floods in the Yellow River. It is necessary to strengthen forecasts and forecasts, consultations and judgments, make overall consideration of the upstream water and the needs of Lanzhou urban flood control, scientifically dispatch Longyangxia, Liujiaxia, Xiaolangdi and other key reservoirs, and implement the prevention of mountain flood disasters and small and medium-sized reservoirs in the middle reaches of the Yellow River, especially the Shanxi-Shaanxi interval. We will strengthen the inspection and defense of key dikes to ensure the safety of flood control.
The third is to do a good job of preventing heavy rainfall in Southwest, South, North and Northeast China. It is necessary to supervise and guide relevant regional and river basin management agencies to strengthen monitoring, forecasting and early warning, strengthen reservoir safety and scientific dispatch, strengthen flood defense of small and medium-sized rivers and dike inspections and defenses, and strictly guard against mountain flood disasters, so as to ensure the safety of the people.
After the meeting, the Ministry of Water Resources dispatched the Three Gorges Reservoir to increase its discharge to 48,000 cubic meters per second; it issued two notices to relevant provinces (autonomous regions and municipalities) and river basin management agencies to deal with flood prevention and response in the Three Gorges Reservoir area and typhoon Arrangements have been made for the prevention of heavy rainfall in "Gauss" and Northeast China and other places; a working group was sent to Chongqing to assist in flood prevention. At present, the Ministry of Water Resources maintains Level III emergency response for flood and drought disaster prevention, and a total of 6 working groups are on the front line to assist local areas in flood and drought disaster prevention work.
