Several Three Gorges Dam Benefits

Three Gorges Dam

The Three Gorges Dam is the greatest project in China. It is a key measure to comprehensively control the middle and down stream of the Yangtze River. The Three Gorges Dam includes power generation, navigation, irrigation, water supply and economy development in reservoir area and some other comprehensive economic benefits. The Three Gorges Dam benefits mainly focus on flood control, power generation and navigation. The Three Gorges Dam is meaningful for speeding up the process of modernization and enhancing overall national strength.

Several Three Gorges Dam Benefits – Flood Control

The Three Gorges Reservoir flood control capacity is 22.15 billion cubic meters, which can effectively control the flood in downstream plain of the Yangtze River which comes from the upstream. If there is hundred-year flood, it can effectively control the flow rate in Jinjiang River section in safe range without the help of flood diversion area in Jinjiang area. If there is thousand-year flood, or the flood as strong as in 1870, it can control the flow rate at Zhicheng Station less than 80000 cubic meters per second. It is the most effective way to prevent the middle stream of the Yangtze River from the flood threaten, to guard against the Jinjiang River section appear devastating disaster.

Several Three Gorges Dam Benefits – Power Generation

The total installed capacity of Three Gorges Hydropower Station is 17.68 million KWH, which can supply to Central China, East China and East Sichuan Areas. Every year, it can replace about 50 million tons coal, which can release the coal transportation pressure of above areas, and relieve the environment pollution which caused by firing coal to generate power.

Several Three Gorges Dam Benefits – Navigation

After the Three Gorges Dam built, the Three Gorges Reservoir will form a 660 kilometers long deep water route as for the backwater. It can improve the waterway condition under Chongqing, Due to many dangerous shoals were submerged, river course became deeper, slopes became slower, flow rate became slower, the conveying efficiency of ships obviously improved, and transportation cost decreased 35 percents to 37 percent than it was. It will greatly improve the development of Yangtze River navigation industry.
