China News Service, August 18th. According to the website of the Ministry of Water Resources, on August 17, Ye Jianchun, the vice minister of the Ministry of Water Resources, chaired a conference to analyze and judge current rain and water conditions and future development trends, and study and deploy heavy rainfall prevention and flood defense. According to the consultation analysis, the Yangtze River and the Yellow River will usher in a new round of flooding, tropical depression will be generated in the South China Sea, and strong rainfall will occur in parts of the southwest. The flood control situation is still very severe. We must continue to overcome fluke and war exhaustion and do not relax. Do a good job in various defenses.

Affected by the recent heavy rainfall, the Yangtze River will have the No. 5 flood of 2020, the upper reaches of the Yangtze River Cuntan, the middle reaches of the Jianli River and Dongting Lake, the upper reaches of the Yangtze River Fujiang, Tuojiang, Jialingjiang, Minjiang, Yunnan Jinsha River Shigujiang section, the upper reaches of the Yellow River 66 rivers including the main stream Lanzhou section, the Weihe River in Shaanxi, the Xuyi section in the middle reaches of the Huaihe River, the Xinyi River in Jiangsu, and the Sunbila River in Heilongjiang, including the upper and middle reaches of the Tuojiang River in Sichuan, the Fuhe River, a tributary of the Minjiang River, the Fujiang River in Chongqing, and the Lueyang River in the upper reaches of the Jialing River in Gansu 13 rivers such as Duan have over-guaranteed. At 16:00 on the 17th, the water level of Cuntan on the upper reaches of the Yangtze River, Jianli River in the middle and lower reaches of the Yangtze River, and Dongting Lake exceeded the alarm by 0.09 to 1.12 meters, and the Xuyi section on the mainstream of the Huai River exceeded the alarm by 0.03 meters.
It is expected that in the next three days, due to the combined effects of cold and warm air, there will be heavy to heavy rains in parts of the central and southern parts of the southwest, the southeastern part of the northwest, most of North China, the northern part of the northeast and the southeastern part, including central Sichuan, central and western Yunnan, and the junction of Sichuan and Yunnan. There will be heavy rainstorms in parts of other places; in addition, affected by the tropical depression on the 19th, there will be heavy rainstorms along the coast of South China, and heavy rainstorms in some parts. Affected by rainfall, 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 in the Haihe River Basin, the upper reaches of the Nenjiang River in the Songliao River Basin, the Songhuajiang River, the Hunhe River, and the upper reaches of the Xijiang River will have obvious flooding processes. , The Cuntan River section and the lower reaches of the Minjiang and Tuojiang Rivers in Sichuan will be over-protected, while the Chongqing Fujiang River will maintain the over-protection. The water level in the middle reaches of Jianli to Lianhuatang and Dongting Lake will rise slightly and exceed the warning; the upper stream of the Yellow River and the Lanzhou section will maintain a large flow. The Tongguan section of the main stream and the lower reaches of the Weihe River will be over-alarm; some rivers in the rainstorm area may have large floods.
According to the consultation analysis, the Yangtze River and the Yellow River will usher in a new round of flooding, tropical depression will be generated in the South China Sea, and strong rainfall will occur in parts of the southwest. The flood control situation is still very severe. We must continue to overcome fluke and war exhaustion and do not relax. Do a good job in various defenses.
One is to make every effort to deal with the No. 5 flood of the Yangtze River. Perform rolling forecasts and forecasts, fine-tune key reservoirs such as the Three Gorges and Danjiangkou, and take overall consideration of upstream inflows, the Three Gorges reservoir area and downstream flood control safety and other factors, rationally control the discharge flow, and give full play to the reservoir's flood blocking and peak staggering role. At the same time, scientifically dispatch the reservoirs on the upper reaches of the Yangtze River to face a new round of heavy rainfall.
The second is to focus on the prevention of mountain flood disasters and the safety of small reservoirs in the southwest. Sichuan, Guangxi, Yunnan, Guizhou and other provinces and regions will usher in the process of strong rainfall. Part of the rain area this time overlaps with the previous period of heavy rainfall. It is necessary to make full use of the mountain flood disaster monitoring and early warning system and the "three major operators" to ensure monitoring and early warning information "Measured and reported," and in accordance with the essentials of "right direction and fast running", remind the grassroots government to do a good job in transferring personnel to avoid danger, and resolutely avoid mountain torrent disasters and casualties. It is necessary to urge reservoirs to implement the "three responsible persons" and "three key links", closely monitor the operation of the project, and achieve early detection, early reporting, and early disposal of dangerous situations.
The third is to do a good job in flood regulation of the Yellow River and flood defense of the Wei River. Continue to strengthen prediction and forecast, scientifically dispatch Longyangxia, Liujiaxia, Xiaolangdi and other key reservoirs, pay special attention to the flood prevention of the Weihe River, a tributary of the Yellow River, strengthen the prevention of floods and mountain flood disasters in small and medium rivers, and earnestly implement various flood prevention responsibilities. The fourth is to strengthen the protection of tropical depression and heavy rainfall. It is necessary to closely monitor the development trend of tropical depression, strengthen monitoring of rain and water conditions and rolling forecasts, focus on strengthening the prevention of mountain torrents in areas affected by typhoons, strengthen water engineering dispatch, ensure the safety of reservoirs during floods, and ensure the safety of people's lives.
At present, the Ministry of Water Resources maintains Level III emergency response for flood and drought disaster prevention, and a total of 5 working groups are on the front line to assist local areas in flood and drought disaster prevention work.
