What is the maximum inflow of the Three Gorges Reservoir?

At 12 on August 20th, the inflow of Three Gorges Reservoir was 75,000 cubic meters per second, and the reservoir water level was 162.42 meters. Zhang Shiming, director of the Hydrological Upstream Bureau of the Yangtze River Committee of the Ministry of Water Resources, said that this is the biggest inflow flood since the Three Gorges Reservoir was built, and it is also the biggest flood peak transit since 198 1 year after the founding of the People's Republic of China.

This flood has set new records since the Three Gorges Reservoir was built: maximum flood peak and maximum discharge. After the flood, it is estimated that the accumulated flood storage will exceed 28 billion cubic meters, equivalent to 2,000 West Lake waters, the first in history? .

Wang Lin, general manager of the Three Gorges Group and commander-in-chief of flood control and disaster relief in emergency headquarters, said that the Three Gorges Water Control Project had discharged flood ahead of schedule, with the water level dropping by 10 meters, and 80% of the flood control storage capacity was reserved, which was well prepared before the war.

Extended data

The role played by the Three Gorges when the flood comes;

First, flood interception, that is, to intercept and store the flood that exceeds the safe discharge of the middle and lower reaches, so as to ensure the flood discharge safety of the Yangtze River below the Three Gorges Project.

The second is peak clipping. When the downstream flood control situation is tense, the large flood peak is clipped from the upstream to reduce the reservoir outflow and relieve the downstream flood control pressure.

Third, the peaks are staggered. Once the downstream flood control situation improves, it is necessary to seize the favorable opportunity, increase the outflow, reduce the water level of the reservoir and vacate the storage capacity.

Experts believe that the Three Gorges Project was built to eradicate the Yangtze River flood, and the flood discharge of the Three Gorges Reservoir is scientific and orderly. The Three Gorges Project is a key factor to control the risks in the Yangtze River basin.
