China News Service, Wuhan, August 19 (Reporter Xu Jinbo) The reporter learned from the Yangtze River Water Conservancy Commission on the 19th that the Three Gorges Reservoir ushered in an inflow of 72,000 cubic meters per second at noon that day, which exceeded the 71200 on July 24, 2012. The cubic meter per second flow rate has become the new largest incoming flow rate since the construction of the library. It is predicted that the Three Gorges Reservoir will see a flood peak of about 75,000 cubic meters per second on the 20th.

  According to the relevant person in charge of the Yangtze River Water Conservancy Commission, affected by the recent heavy rainfall, the Minjiang, Tuojiang, and Jialingjiang tributaries of the upper reaches of the Yangtze River have experienced floods of over-guarantee and above.

  Over-alarm and above floods occurred in the Yibin-Cuntan section of the upper reaches of the Yangtze River. Luzhou, Zhutuo, and Cuntan stations exceeded the guaranteed water level. At 10:30 on the 19th, a flood peak water level of 242.63 meters appeared at Luzhou Station (0.63 meters beyond the guarantee). At 16:00 on the 19th, the water level at Zhutuo Station rose to 214.52 meters (2.52 meters over protection), and the corresponding flow was 48,000 cubic meters per second; the water level at Cuntan Station rose to 190.24 meters (6.74 meters over protection), and the corresponding flow was 73,600 cubic meters per second . It is estimated that there will be a peak water level of about 192.1 meters at Cuntan Station on the 20th, and the corresponding flow rate will reach about 75,000 cubic meters per second.

  Affected by the above-mentioned inflow, the inflow of the Three Gorges Reservoir increased rapidly. At 12:00 on the 19th, the inflow of the Three Gorges Reservoir rose to 72,000 cubic meters per second, exceeding the maximum inflow since the construction of the reservoir (71200 cubic meters per second, July 24, 2012). day). Since then, the flow of the Three Gorges reservoir has continued to rise. The flow of the reservoir has risen to 74,000 cubic meters per second at 22:00 on the 19th. It is expected that there will be a flood peak of about 75,000 cubic meters per second on the 20th.

  In response to the current round of flood No. 5, the Yangtze River Water Resources Commission upgraded the flood and drought disaster prevention emergency response to level II at 19:00 on the 18th; 9 dispatch orders were issued in a row to jointly dispatch the Jinping I and Ertan reservoirs on the upper reaches of the Yangtze River. Jinsha River Guanyinyan, Wudongde, Xiluodu, Xiangjiaba Reservoir, Wujiang Pengshui Reservoir, coordinated Sichuan Province to dispatch Jialing River Tingzikou and Minjiang Pubugou Reservoirs to intercept floods and reduce the peak flow into the Three Gorges Reservoir; coordinate upstream and downstream flood control, Adjust the outflow of the Three Gorges Reservoir and reduce the water level in front of the Three Gorges Reservoir; release to the water conservancy departments (bureaus) of Sichuan, Yunnan, Chongqing, Hubei, and Hunan provinces (municipalities), Wudongde, Xiluodu, Xiangjiaba and other reservoir construction and operation management units The notice requires effective management of flood control and safety in the Yangtze River Basin in the near future to ensure the safety of people’s lives.

  At present, the Three Gorges Reservoir has opened 10 flood discharge holes, and its discharge volume has reached 49,400 cubic meters per second at 22:00 on the 19th. This has also created the largest discharge volume since the construction of the Three Gorges Reservoir. It is expected that the middle and lower reaches of the Yangtze River will usher in a new round of flooding. process. To this end, the Hydrological Bureau of the Yangtze River Water Conservancy Commission issued at 11 o'clock on the 19th: Orange warning for floods in the upper reaches of the Yangtze River from Yibin to Cuntan, Jialing River and Three Gorges Reservoirs, Shigu River section of Jinsha River, Shashi to Lianhuatang River section of the middle reaches of Yangtze River, Dongting Lake area Yellow flood warning and blue flood warning in Panzhihua River.
