Each department deployed flood control work, and 6 small and medium-sized rivers in China experienced over warning flood in Sichuan | rainstorm | Department
Recently, heavy rainfall has occurred in some areas of Northeast China, as well as in the central and eastern parts of Jiangnan. Affected by this, six small and medium-sized rivers in Liaoning and Zhejiang have experienced over warning floods.
The important flood situation report released by the Ministry of Water Resources on the 23rd shows that six small and medium-sized rivers, including the Yangximu River, the upper reaches of the Raoyang River, and the Dongsha River, a tributary of the Liaohe River in Liaoning Province, as well as the Dongheng River, Zhoujialu River, and Gaobeipu River in the Yongjiang River system in Zhejiang Province, have experienced over alert floods, with a maximum over alert range of 0.06 to 0.52 meters; There are 11 stations in the river network area around the Taihu Lake Lake whose water level exceeds the alarm by 0.01 to 0.31 meters, of which Wangjiangjing Station exceeds the alarm by 0.01 meters.
On the 23rd, Heilongjiang, Inner Mongolia, Jilin and other places still experienced strong rainfall. The water conservancy department predicted that from 8:00 on the 23rd to 8:00 on the 24th, the upstream of Weihe River in Gansu Province, the upstream of Dadu River in Sichuan Province, Raoyang River, a tributary of Liaohe River in Liaoning Province, Nemoer River and Wuyur River in Heilongjiang Province, Le'an River, Changjiang River, Xinjiang River, Ganjiang River, a tributary of Poyang Lake in Jiangxi Province, and Jinjiang River, a tributary, will be flooded, and some small and medium-sized rivers in the rainstorm area may be flooded beyond the warning limit.
In response to the recent heavy rainfall in Northeast China, the Ministry of Emergency Management is supporting emergency rescue forces across provinces and regions with 6347 personnel, including 4800 national comprehensive fire rescue teams, 500 engineering rescue forces, 1047 drainage forces, 680 sets of drainage equipment, and 6 helicopters.
At present, it is a critical period for flood prevention during the "Seven Down and Eight Up" period. During this period, the north entered the main rainy season; At the same time, typhoon activity in the South China Sea and Western Pacific has entered an active period, and coastal areas are susceptible to typhoon precipitation and storm surges.
According to the forecast of the meteorological department, from 23rd to 25th, Sichuan Basin will usher in a new round of rainfall process. There will be rainstorm in parts of Sichuan, Chongqing and other places, and heavy rainstorm in the local area. From 24th to 25th, the rainfall will be concentrated.
On the morning of the 23rd, the Ministry of Water Resources issued a "one order for one province" to eight provinces and autonomous regions in Inner Mongolia, Jilin, Heilongjiang, Jiangxi, Sichuan, Gansu, Qinghai and Ningxia, reminding them to do a good job in rainstorm and flood prevention and response, and sent three working groups to Zhejiang, Chongqing and Sichuan to guide flood prevention.
According to the prediction of the National Climate Center, China will experience both severe drought and flood during this year's "Seven Down and Eight Up" period. The precipitation in the eastern part of the Songhua River Basin and the eastern part of the Liaohe River Basin will be more than 20% higher than the same period in normal years, which may lead to severe flood and waterlogging disasters; The precipitation in the west of Songhua River basin, Nenjiang River basin, the west of Liaohe River basin, the east of Haihe River basin, the east of Huaihe River basin, the lower reaches of Yangtze River basin, the Taihu Lake Lake basin and the Pearl River basin is more than 10% to 20%. It is necessary to pay attention to the local flood disaster that may be caused by the periodic heavy precipitation process.
The National Flood Control Administration previously held a special meeting to discuss and deploy key flood control and disaster relief work during the critical period of "seven down and eight up". The meeting emphasized the need to highlight the focus of work, making watershed flood prevention a top priority in flood control work, and focusing on weak links such as mountain flood geological disasters, floods in small and medium-sized rivers, and safe flood control of small and medium-sized reservoirs.
The China Meteorological Administration has recently further deployed meteorological services during the critical period of flood prevention, proposing to fully utilize modern monitoring methods such as meteorological satellites and radars, scientifically analyze the time periods and regions affected by heavy rainfall, and do a good job in monitoring, forecasting, and early warning of heavy rainfall. At the same time, strictly follow the "call for response" standards and procedures, timely activate early warning "call for response", and strengthen consultation and linkage with water conservancy, emergency management, natural resources and other departments at all levels.
Wang Zhangli, Deputy Director of the Water and Drought Disaster Prevention Department of the Ministry of Water Resources, stated that the "seven down and eight up" flood prevention critical period has arrived, and the water conservancy system has fully activated the flood prevention critical period defense mechanism, strengthened the "four pre" measures of forecasting, early warning, rehearsal, and contingency plan, implemented various defense measures, and made every effort to respond well to flood situations.
