The flood control situation is grim. How to rescue and provide disaster relief in case of a big flood?

Tian, director of the flood and drought disaster prevention department of the Ministry of Water Resources, said that since the flood season this year, there have been 18 heavy rainfall processes in the country, the strongest since June 2. This heavy rainfall process involves 12 provinces and cities, with a large rainfall range and great intensity. The rainfall area above 400 mm is more than 24,000 square kilometers, the coverage area above 250 mm is about 90,000 square kilometers, and the rainfall area above 100mm is more than 700,000 square kilometers, which is very large and strong. For example, the rainfall in longtan town, Huizhou, Guangdong is over 1 140mm, and that in Su Ying, Guilin, Guangxi is 740mm. The heavy rainfall caused floods in some provinces. For example, a small reservoir in Guangxi Autonomous Region was dam-broken due to heavy rainfall. The rainfall in this reservoir area exceeds the flood control standard of the reservoir. Due to the early warning of the local government and the early transfer of personnel, no casualties were caused. Yong Han Dike, the second tributary of Dongjiang River in Huizhou, Guangdong Province, was dam-broken due to excessive flood, which flooded two villages. The affected population was about 3,000, but there were no casualties. At present, the rainfall process is coming to an end, but there is another rainfall process behind it.

The most critical period of flood control in China is 6? In August, especially in the south, Jiangnan has already entered Mei. The meteorological department predicts that there will be more rainfall in the south this year, so the flood control situation is very severe this year, so we should be prepared for the big flood.

Tian introduced that the water conservancy department should focus on two aspects: one is to manage flood control projects well, and the other is to make good use of flood control projects. At present, there are more than 300,000 kilometers of five-level dikes, 98,000 reservoirs, 654.38+10,000 dams and1654.38+10,000 hydrological stations in China. First of all, these projects should be well managed to ensure their own safety, so as to play a role in flood control. Before the flood season this year, the Ministry of Water Resources sent a working group to inspect these projects one by one to see if there are problems and weak links, and urged rectification to ensure safety during the flood season.

In flood control projects such as making good use of reservoirs, reservoirs should play the role of blocking flood peaks. Last year, more than 2,500 reservoirs across the country played a role in peak regulation and peak shifting, with very good results, with more than 654.38+05 billion cubic meters of flood interception. For example, the Three Gorges Reservoir lowered the water level to1.45m on June 8th, two days ahead of schedule. There is also the role of dikes, and inspections should be carried out in flood season to ensure the safety of dikes and give play to the role of dikes in flood suppression. There are also some pumping stations and some gates to be inspected to ensure that they can be used normally when needed. When the reservoirs and dikes play a full role and the flood cannot be treated, it is necessary to use the flood storage and detention areas to store some floods to ensure the safety of major targets, important cities and important facilities.
