Ministry of Water Resources: Huaihe River mainstream flood is expected to evolve downstream, Wujiadu section may exceed the alarm

  Xinhua News Agency, Beijing, July 21 (Reporter Hu Lu) According to weather forecasts, from July 21 to 23, there will be heavy rainfall in the northeast and southwest, southeast of northwest, south of North China, Huanghuai, and northern Jianghuai, with a cumulative rainfall of 30 To 70 mm. The Ministry of Water Resources recently estimated that due to rainfall and upstream water, floods in the mainstream of the Huai River will evolve downstream, and the Wujiadu section may exceed the alarm.

  According to monitoring by the Ministry of Water Resources, at 17:00 on the 21st, the water level of Wangjiaba on the Huaihe River was 29.30 meters, which was the same as the guaranteed water level. The section from Wangjiaba to Nanzhaoji and Wangji to Linhuaigang exceeded the protection level of 0.04 to 2.05 meters; the water level of the Lotus Pond on the Yangtze River was 34.39 meters, which was low. At the guaranteed water level of 0.01 meters, the water level in the middle and lower reaches of the main stream below Shitou and the two lakes exceeded the warning level by 0.73 to 2.20 meters; the average water level of Taihu Lake was 4.78 meters, which exceeded the protection level by 0.13 meters. It is expected that the water level of the section from the main stream of the Yangtze River to Hankou and Dongting Lake will continue to rise. The water level of the Lianhuatang River section and Dongting Lake will be over-protected, and the water level of Lake Tai will continue to fluctuate at high levels.

  Minister of Water Resources E Jingping said at the meeting on the 21st that the current period is at the critical period of flood prevention. The Yangtze River, Huaihe River and Taihu Lake continue to have high water levels. There are still heavy rainfalls in some areas recently. We must proceed from the most unfavorable situation. , Storage and discharge coordination, fine dispatch of water projects, strengthen inspections and defenses of dikes, and do their best to prevent floods.

  The first is that the Huai River will fixate on Wangjiaba and Hongze Lake. It is necessary to comprehensively consider the flood control situation of the upstream and downstream of Wangjiaba, in-depth study of the follow-up operation of the Mengwa flood storage area, rational flood storage, and timely closure of the gate. The Huaihe River Basin forecasts that there will still be rainfall in the future. It is necessary to fully estimate the possibility of flooding again, set up a good chess game, play a good first move, Hongze Lake speeds up the discharge, and reduces the water level as much as possible.

  Second, the Yangtze River must focus on the Three Gorges and the middle and lower main dikes. It is necessary to keep an eye on the water levels of the Three Gorges and Jianli, Lianhua Pond, Hankou, etc., coordinate the upstream and downstream, rolling forecast and forecast, fine analysis and calculation, and scientifically dispatch key reservoirs such as the Three Gorges and Danjiangkou. On the premise of ensuring the safety of the downstream main embankment, the water level of the Three Gorges Reservoir should be reduced as much as possible to prepare for the possibility of another flood in the upper reaches of the Yangtze River. At the same time, it is necessary to closely follow up and understand the situation of the main dikes in the middle and lower reaches, and be well aware of the state of the dikes, flood discharge capacity, inspection and defense, etc.

  Third, Taihu Lake must focus on the levee surrounding the lake and the surrounding river network. It is necessary to closely follow the changes in the water level of Taihu Lake, coordinate the Taihu Lake and the surrounding river network according to the actual situation, scientifically arrange drainage measures, strengthen the inspection and defense of the lake dykes and river network fences to ensure safety.

  The fourth is to focus on mountain torrents and small reservoirs in areas with heavy rainfall. Sichuan, Chongqing and other places were repeatedly affected in the early stage, and heavy rainfall in the Yimeng Mountains and Jiaodong Peninsula can easily cause disasters such as mountain torrents. We must conscientiously implement various measures such as flood safety of small reservoirs, mountain torrent disaster prevention, and flood prevention of small and medium rivers.
