China News Service, Guangzhou, July 14 (Reporter Wang Jian) ​​"In June 1915, a huge flood occurred in the Pearl River Basin, and the city of Guangzhou was flooded for 7 days and 7 nights, killing and injuring more than 100,000 people; in June 2022, the Beijiang River in the Pearl River Basin once again. No one was injured or injured in a major flood, which ensured the safety of the Pearl River Delta urban agglomeration." Wang Baoen, executive deputy commander of the Pearl River Defence General Administration and director of the Pearl River Water Conservancy Commission of the Ministry of Water Resources (hereinafter referred to as the "Pearl River Commission"), was interviewed by a reporter from Chinanews.com on the 14th. Say.

　　From May to June this year, a total of 11 heavy rainfalls occurred in the Pearl River Basin, 230 rivers experienced excessive floods, and 6 numbered floods occurred in the Xijiang and Beijiang.

　　Wang Baoen told reporters that in the face of the extremely severe and complex flood control situation in the Pearl River Basin, under the leadership of the National Defense General Administration and the Ministry of Water Resources, all parties in the basin worked together to strengthen The "four major" measures of joint dispatch of reservoir groups and coordinated operations of various regions have achieved the "four no" goals of no casualties, no dam collapse of reservoirs, no breach of the main embankment of the Beijiang and Xijiang Rivers, and no flooding of the Pearl River Delta urban agglomeration. Hard battle.

　　"Faced with the huge historical flood, we have prevented it!" Wang Baoen said firmly.

　　On June 19, the No. 4 flood this year occurred in the Xijiang River in the Pearl River Basin, and the No. 2 flood this year occurred in the Beijiang River.

At 22:00 on June 21, in view of the development of the No. 2 flood in the Beijiang River into a catastrophic flood, the Pearl River Defence Directorate launched a flood control level I emergency response.

　　At the critical moment of flood prevention, Minister of Water Resources Li Guoying has repeatedly contacted the Pearl River Committee and Guangdong Province to discuss the deployment of flood prevention work in the Pearl River Basin, and went to the Xijiang and Beijiang Rivers in the Pearl River Basin to command and dispatch flood control work on site.

Liu Weiping, vice minister of the Ministry of Water Resources, presided over many meetings and arranged the deployment of flood control work in the basin.

At the same time, Lan Lan, the commander-in-chief of the Pearl River Defence Committee, also listened to the flood control work reports of the Pearl River Delta Committee for many times, and went to the front line to guide the flood control work.

　　In accordance with the deployment requirements of the Ministry of Water Resources, the Pearl River Commission has focused on the four "four-points": rainfall - runoff - confluence - evolution, total amount - flood peak - process - dispatch, watershed - main stream - tributary - section, technology - material - team - organization and so on. "a chain" to precisely control the entire process and each link of flood defense.

　　"For each heavy rainfall process, the Pearl River Commission analyzes and judges the flood control situation and hidden dangers by basin, region, and river section, accurately identifies defense objects and defense targets, and formulates targeted defense measures." Wang Baoen has repeatedly emphasized.

　　In the face of the severe flood control situation, the Pearl River Committee closely tracks the changes in the rainwater conditions in the basin, conducts daily consultations and judgments, makes full use of the flood control "Four Predictions" platform, scientifically analyzes the flood control situation and defense risks, updates flood forecasts on a rolling basis, and issues flood warnings 33 times and early warning text messages. More than 20,000 items provide strong support for command and dispatch decision-making and flood defense.

　　At the same time, it is also a powerful measure for the flood control work of the Pearl River to carry out the unified dispatch of flood control of reservoir groups.

The Pearl River Commission adheres to the principle of "defense is king", considers the upstream and downstream, left and right banks, main and tributaries, conducts rolling analysis and calculation, accurately grasps the flood evolution process and the safety bearing capacity of the Xijiang River, the lower reaches of the Beijiang River and even the Pearl River Delta, dispatches the backbone reservoirs in the river basin in advance, and conducts joint surveys. Joint control to block floods and cut peaks.

　　In the face of the flooding process of the Xijiang River, the Pearl River Committee and the Guangxi Water Resources Department dispatched 24 reservoirs in the main and tributaries of the Xijiang River to store 3.8 billion cubic meters of floodwater.

Longtan, Baise and other large upstream reservoirs are doing their best to block floods; Hongshuihe Yantan, Liujiang Luojiu, Yujiang Xijin, Guijiang Qingshitan and other tributary reservoirs are staggered in time; in the construction of the Dateng Gorge project, it plays a key role in controlling, Precise peak shaving, through the joint dispatch of reservoir groups, successfully reduced the flood peak of Wuzhou Station by 6,000 cubic meters per second, lowered the water level by 1.8 meters, and pushed the flood peak time by one day, successfully avoided the bad floods of the Xijiang and Beijiang, and released the Beijiang floods safely. Create favorable conditions.

　　In the face of the water conditions, industrial conditions and disaster conditions of the Beijiang flood, the Pearl River Committee promptly proposed the Beijiang flood storage, flood detention and flood diversion scheduling plan to the Guangdong Provincial Department of Water Resources, and guided the use of the Feilaixia Reservoir and the Nujiang flood storage and detention area.

Through the joint dispatch of the Beijiang River Basin Flood Control Engineering System, the peak flood flow of Beijiang Shijiao Station was reduced to 18,500 cubic meters per second, the flood level was successfully controlled to a safe discharge, the water level in the northern mainstream of the Pearl River Delta was lowered by 0.3 meters, and the Beijiang Embankment and the Pearl River were ensured. Flood control safety of the delta city group.

　　Wang Baoen said that flood control is a complex and systematic task involving various departments and fields. It is necessary to coordinate the upstream and downstream, left and right banks, main and tributaries, and adhere to a game of chess in the river basin.

　　Wang Baoen pointed out that as the first typhoon "Siamba" to land in China this year landed on the coast of Dianbai, Maoming, Guangdong on July 2, the prelude to the active typhoon period in the Pearl River Basin has begun.

The Pearl River Committee will continue to tighten the string of flood control, do a solid job of preventing and responding to storms and floods, and firmly hold the bottom line of flood control safety.
