I want to ask, if the Three Gorges collapses, will Xinyang City, Henan Province be flooded? How deep will it be if it is flooded? How many hours does it take for ocean currents to reach Xinyang?

The Three Gorges will not collapse. The Three Gorges Project was built to resist the attack of low-yield nuclear weapons. The Three Gorges Dam is a concrete gravity dam and the strongest dam type. It is not only not afraid of long-term floods, but also will be more and more resistant to pressure in 100 years.

According to the opinion of the expert group of the Ministry of Water Resources, the flood control capacity of the Three Gorges Dam can be divided into two parts: "saving people" and "saving themselves". "Saving people" refers to the flood control ability of the Three Gorges Dam to ensure the downstream flood control safety, that is, the ability to help the downstream flood control.

In the event of a flood that does not exceed "once in a hundred years" (the peak flow exceeds 83,700 cubic meters per second), the Three Gorges Project can control the maximum flow of Zhicheng Station to not exceed 56,700 cubic meters per second, and the water level in Shashi can not exceed 44.5 meters without flood diversion project, so the Jingjiang reach can safely discharge flood.

In case of "once in a thousand years" flood, the corresponding flow through Zhicheng will not exceed 80,000 cubic meters per second after being regulated by the Three Gorges Reservoir. With the application of Jingjiang flood diversion project and other flood diversion and storage measures, the water level in Shashi can be controlled within 45 meters, thus avoiding the possible devastating disasters in Dongting Lake Plain and Jianghan Plain on the north and south sides of Jingjiang River.

Extended data

"The Three Gorges Project is the backbone project for flood control in the Yangtze River. Mainly solve the problem of flood control in the main stream, cut the flood peak in time, and reduce the flood control burden of Jingjiang and Chenglingji in the middle and lower reaches of the Yangtze River. " Wang Hai, deputy director of the Hub Operation Department of the Three Gorges Hub Construction and Operation Administration, introduced.

The flood control capacity of the Three Gorges Reservoir is 2.2 1 0.50 billion cubic meters, and with1upstream reservoir 2 1, the total flood control capacity is 38 billion cubic meters, which is dispatched by the Yangtze River Defense General Administration and the State Defense General Administration.

Cheng Xiaotao, an expert on flood control and disaster reduction in China Academy of Water Resources and Hydropower Research, pointed out that the primary task of building the Three Gorges Project in that year was to prevent the Jingjiang levee from collapsing. Jingjiang levee is located in the upper reaches of Wuhan and the lower reaches of Zhicheng. Whether it is decided in the south or the north, it may endanger the lives and property of more than 8 million people. Therefore, there used to be a saying that "the Yangtze River is in Jingjiang". No other measures can replace the flood control function of the Three Gorges Dam.

What is the flood control capacity of People's Network-Three Gorges Project? Is it related to the flood in Hubei?
