Up to now, the Three Gorges dam is the most comprehensive water control project in the world

The Three Gorges project is the water conservancy project with the largest comprehensive benefit in the world so far, playing a huge flood control and shipping benefits. After the completion of the Three Gorges Dam, a 600 km long reservoir has been formed, which has become a rare new landscape in the world. In December 2015, the Three Gorges dam was selected as one of the 30 Best New Tourism Landscapes in the Three Gorges of the Yangtze River.

After the completion of the project, the normal water level of the reservoir will be 175 meters, the flood control storage capacity will be 22.15 billion cubic meters, and the total storage capacity will reach 39.3 billion cubic meters. It will give full play to the key role of the flood control system in the middle and lower reaches of the Yangtze River, and will significantly improve the 660 km waterway from Yichang to Chongqing. The 10000 ton fleet will be able to reach Chongqing port directly, which will play a role in flood control, power generation, shipping, breeding, tourism and south to north water diversion Ten benefits, such as water supply and irrigation, are unmatched by any giant power station in the world.

Flood control benefits of Three Gorges Dam

During the operation of the Three Gorges reservoir, the reserved flood control capacity is 22.15 billion cubic meters, and the peak flow can be reduced by 27000-33000 cubic meters / second by flood regulation, which is the most water conservancy project in the world.

Shipping benefits of the Three Gorges Dam

The Three Gorges reservoir will return water to Chongqing, a key town in Southwest China. It will improve the navigation mileage by 660 kilometers and increase the annual one-way navigation capacity from 10 million tons to 50 million tons. It is worthy of calling the Three Gorges project the first hub project in the world to improve navigation conditions.

Drought resistance function of Three Gorges Dam

In the case of severe drought in the lower reaches, the Three Gorges project can increase the discharge of water and increase the discharge to effectively alleviate the drought situation. Zheng Shouren, chief designer of the Three Gorges project, chief engineer of the Yangtze River Water Conservancy Commission and academician of the Chinese Academy of engineering, said that drought resistance is a new function of the Three Gorges Project. He said: the Three Gorges project is designed only for flood control, power generation, navigation and water supply. The function of water replenishment is to consider the residents and production water on both sides of the lower reaches, but also to meet the needs of drought resistance. This part of water demand is relatively large.

Now, the 17 year construction period of the Three Gorges project has been fully completed, and the world-famous Three Gorges dam has shown its majestic appearance. It is particularly gratifying that the Three Gorges builders have not only created a number of world records in the history of hydropower construction, but also controlled the quality of the completed unit projects, all of which have passed the quality assessment.

Power generation function of the Three Gorges Dam

The Three Gorges hydropower station is the largest hydropower station in the world with a total installed capacity of 22.5 million kilowatts and an annual power generation capacity of more than 100 billion kwh.

In the construction history of China and even the world, the Three Gorges dam is a heavy stroke and a miracle of human water control project.
