China News Service, July 21. According to the website of the Ministry of Water Resources, there have been torrential rains and floods in many rivers in Henan and other places recently. The rescue work for the Guojiazui Reservoir in Zhengzhou is still underway. The Ministry of Water Resources is instructing the Henan Provincial Department of Water Resources to handle the torrential rains and floods. While taking precautions, urgently deployed the Construction Management Bureau of the Middle Route of the South-to-North Water Diversion Project to prepare for various responses.

  Since July 17, heavy rains have been experienced in northern China, western Huanghuai, central and northern Jiangnan, southeastern southeast, eastern Hubei, northeastern Inner Mongolia, and northwestern Heilongjiang, including central and northern Henan, southern Hebei, and southern Shanxi. Partial areas fell from torrential rain to heavy rainstorms, and partly with extremely heavy rainstorms. The accumulated maximum rainfall was 884 millimeters in Jiangang, Zhengzhou, Henan.

46 rivers in 14 provinces across the country have over-warranty floods, with a maximum super-warning range of 0.01 to 2.50 meters, of which 7 are super-guaranteed and 4 are super-historical.

Typhoon No. 7 "Chapaka" landed on the coast of Yangjiang, Guangdong at 21:50 on the 20th. The maximum wind force near the center was 12 when it landed, and it was located in Yangjiang at 6 on the 21st, with a wind force of 8. At present, the coastal rivers of Guangdong and Guangxi were stable.

  From 8:00 on the 17th to 6:00 on the 21st, the cumulative average rainfall in Henan Province was 108 mm, of which Zhengzhou was 345 mm and the maximum rainfall was 884 mm in Jiangang; Jiaozuo was 218 mm and the maximum rainfall was 314 mm at Jiaozuo Meteorological Station; and Xinxiang was 211 mm. The maximum rainfall is 324 mm at Yanjin Meteorological Station; Pingdingshan is 180 mm, and the maximum rainfall is 363 mm at Lushan Zhongtang.

Affected by heavy rainfall, the Yihe River, a tributary of the middle reaches of the Yellow River in Henan Province, the Jialu River, a tributary of the upper reaches of the Shaying River in the middle reaches of the Huai River, and the Dasha River, the Communist Canal and Weihe River, a tributary of the Zhangweinan Canal in the southern part of the Haihe River, have been flooded. Historical flood.

At 7 o'clock on July 21, the water level of the Zhongmu Hydrological Station of the Jialu River rose to 79.40 meters, exceeding the historical highest water level of 1.71 meters, and the corresponding flow was 600 cubic meters per second. The water level and flow both ranked first since 1960; Dasha River, Communist Chaoqu and Weihe super police are 0.22m to 0.96m.

  In the Zhengzhou Changzhuang Reservoir that was in danger on the 20th, 13 piping has been dealt with and the danger was effectively controlled. The water level of the reservoir was 128.67 meters at 7 o'clock on the 21st, down 2.64 meters from the peak.

The downstream dam slope of the Guojiazui Reservoir (small (1) type) on the Jinshui River in Erqi District of Zhengzhou collapsed on a large scale, but no breach occurred.

At present, the top of the dam is basically no flow, and the local area is continuing to expand the temporary discharge channel to lower the water level of the reservoir.

  While guiding the Henan Provincial Department of Water Resources to prevent rainstorms and floods, the Ministry of Water Resources urgently deployed the Construction and Management Bureau of the Middle Route of the South-to-North Water Diversion Project to prepare for various responses.

First, at 0:30 on the 21st, the canal head diversion sluice further reduced the flow into the canal to 50 cubic meters per second, and successively opened the upstream retreat sluice to return water.

Significantly lower the opening of the upper and lower reaches of the Jinshui River to reduce the impact on the main canal as much as possible.

The second is to organize the emergency evacuation of all operation and management personnel in the canal section of the Jinshui River upstream and downstream that may be affected by the dam failure flood of the Guojiazui Reservoir.

The third is that the gates of the canal sections within the affected area of ​​the dam-break flood shall be maintained for remote dispatch and operation, and the sections outside the affected area shall be prepared for on-site manual control of communication interruption.

The fourth is to urgently report the danger to the four provinces and cities of Beijing, Tianjin, Hebei, Henan and make preparations for water cuts and water source switching.

At present, the general main canal of the middle route of the South-to-North Water Transfer Project is operating safely.

  It is expected that in the next three days, affected by cold and warm air and typhoons, there will be heavy to heavy rains in southern North China, northwestern Huanghuai, southern southern China, eastern Jiangnan, and southern Yunnan, including southern Hebei, northern Henan, southeast Shanxi, and southern Guangxi , Southeastern Guangxi and other places will have heavy rainstorms, and local extremely heavy rainstorms.

It is expected that the Zhangwei River, Ziya River, Daqing River in the Haihe River Basin, Yiluo River, Qin River, and Fen River in the middle reaches of the Yellow River, Hongru River and Shaying River in the Huai River Basin, and the Pearl River Basin along the southern coast of Guangxi and the coast of Western Guangdong will appear obvious During the flooding process, some small and medium-sized rivers in the rainstorm area may have floods above warning level.

In addition, affected by the upstream water, part of the main stream of the middle and lower reaches of the Nenjiang River and the Zhaoyuan section of the upper Songhua River will exceed the alarm.
