Advantages of Three Gorges Dam

As the largest water conservancy project in the world, the Three Gorges Dam Project has flood control, power generation, navigation, irrigation, tourism and some other advantages

Advantages of Three Gorges Dam – Flood Control

After Three Gorges Dam completed, there will form a giant reservoir to block flood and store water, making the flood control capacity of the Jinjiang River Dam in down stream greatly improve to hundred-year flood from ten-year flood, and the reservoir storage capacity is between 7.3 to 22 billion cubic meters. If there is a flood which as strong as in 1954, the Three Gorge Dam can decrease 1 to 1.5 billion cubic meters under the standard, the river course from Jinjiang to Wuhan need to reduce 35 to 40 billion cubic meters flood. Even the flood in 1998 can be effectively defended.

Advantages of Three Gorges Dam – Power Generation

The Three Gorges Hydropower Station is the largest hydropower station in the world, which total installed capacity is 18.2 billion KW. The annual power generation capacity of Three Gorges Hydropower Station is equal to the full energy of 40 million tons standard coal fully burned. The annual power generation capacity of Three Gorges Hydropower Station is 84.68 billion degree, which mainly supply to Central China, East China, North China, Chongqing and some other areas.

Advantages of Three Gorges Dam – Navigation

The Three Gorges Dam is located on the conjunction place of upstream and middle stream of the Yangtze River. The geography location of Three Gorges Dam is very good, which can channelize the river course between Sandouping and Chongqing for the upper side, and increase the water flow rate in the middle stream of the Yangtze River below Gezhouba dam in dry season. It can relatively fully improve the navigation condition between Chongqing and Wuhan, to satisfy the navigation industry development in the upstream and midstream of the Yangtze River. The navigation capacity can increase to 50 billion tons from present 10 million tons in one year

Furthermore, the advantages of Three Gorges Dam also include aquiculture, tourism, ecology protection, environment purification, development immigration, South-to-North water diversion, water supply and irrigation and so on.
