From July 11 to 16, there will be a moderate to heavy rain and local rainstorm in the Yangtze River basin from west to east, and the Minjiang River, Tuojiang River and Jialing River will rise. In the flood control conference room of the Yangtze River Water board, intensive research and judgment were carried out, and orders were sent out. At 6:00 on the 7th, Wangjiaba Station on the main stream of the Huaihe River had a peak water level of 25.3 meters, and six stations in Lixia River area had exceeded the warning level... At present, the Huaihe River basin has entered the plum rain season, and the Water board of the Huaihe River has issued 30 work lists for the main flood season to start the working mechanism for the main flood season. What is the current trend of the national flood situation from the start of the flood on March 24th? How is the current progress of flood prevention work? How to win the initiative for flood prevention? Small and medium-sized rivers are prone to frequent floods, and the time is relatively concentrated. "In general, the flood situation of rivers is generally stable, rainstorm floods occur in parts of the south, and periodic droughts occur in the southwest and other places." Yao Wenguang, director of the Department of Water and Drought Disaster Prevention of the Ministry of Water Resources, analyzed that the current flood situation is characterized by "two more and two less". Small and medium-sized rivers are prone to frequent floods, the total water storage of reservoirs in the country is slightly more, and the precipitation in the country is generally less, The overall runoff of major rivers is relatively low. The 17 heavy rainfall processes that have occurred since the beginning of the flood season have caused 234 rivers in 18 provinces to experience over warning floods. Most of them are small and medium-sized rivers, and there are 25 small and medium-sized rivers that have experienced over guaranteed floods, "Yao Wenguang said. Moreover, the flood occurred in a concentrated period, with 147 rivers experiencing over alarm floods since June 22, accounting for 63% of the total since the flood, which poses certain challenges to flood prevention work. What is the flood situation of major rivers? According to the statistics of the Ministry of Water Resources, the current water level of major rivers is generally low. The water level of the main stream of the middle and lower reaches of the Yangtze River, Dongting Lake and Poyang Lake is 3.03 to 5.32 meters lower than that of the same period of the year, and the water level of the main stream of the middle and lower reaches of the Yellow River is 0.53 to 3.60 meters lower. "Large rivers involve a wide range of areas and have a large impact. There are towns, industrial parks and important infrastructure around them, so we must not take it lightly." Yao Wenguang said that this year, the Ministry of Water Resources timely revised and approved the joint regulation scheme of annual important reservoirs in the Yangtze River, Yellow River and the Pearl River basins, and the flood and water regulation scheme of the the Taihu Lake Lake basin. The practical exercises for flood control scheduling in the seven major river basins have been comprehensively carried out, effectively testing plans, training teams, and enhancing capabilities. How will the flood situation develop next? It is predicted that from July to August, the climate situation will be moderate to moderate, with more extreme weather and climate events, as well as regional floods, droughts, and heatwaves. In terms of drainage basins, Songhua River, the middle reaches of Heilongjiang, Liaohe River Hunhe River Taizi River, Huaihe River and Yishusi River, Chuhe River Qingyi River, Shuiyang River, the Taihu Lake Lake and Qiantang River, tributaries of the lower reaches of the Yangtze River, may have major floods. In addition, drought may occur in central and western Inner Mongolia, central and northern Shaanxi, Shanxi, and other areas, while periodic high-temperature heatwaves may occur in North China, central and southern China, and southwestern and northeastern China. The relevant person in charge of the Ministry of Water Resources stated that it is necessary to coordinate flood control and drought resistance needs, implement precise policies, fully leverage the flood control and peak shaving functions of water conservancy projects, and strive to increase drought resistance water sources while ensuring flood control safety. Especially, it is necessary to be vigilant against sudden changes in drought and flood, and be prepared. Pay close attention to weak links and weave a dense protective net for rivers, lakes, and reservoirs. On July 4th, "Qijiang 202
