What is the largest dam in the world?

The largest dam in the world is the Three Gorges dam on the Yangtz River in China. Structural work was completed in 2006. The dam is 2 309 m high (1.4 miles) and 185 m 607 ft), six times larger size of the Hoover dam. When its generators are installed and will be online at the beginning of 2009, it will be the largest power plant in the world. The Three Gorges dam will generate 18.2 GW or about 2% of China's total energy consumption. The Chinese exploding economy needs power and has been caused by considerable efforts to alternative forms of energy that pollute air because the Chinese primary energy source is coal. More than 1,000,000 people had to be evacuated to avoid the flood he created, which is 660 k (410 miles) long and immerses 632 km of land. As part of the preparation for construction, 1200 towns and villages were moved. After the incident in 1975 during Super Typhoon Nina, KDEV as a result of the catastrophic failure of the dam was killed by 140,000 people, other preventive measures in the engineering andDamage tolerance of the Three Gorges dam. It will be guarded by a large number of soldiers continuously to discourage possible terrorist attacks.

Despite frequent critics reported that the cost of the Three Gorges dam could be up to $ 100 billion in the US (USD), the actual costs are unlikely to exceed $ 22.5 billion. Most of this is paid by the national electricity tax. Officials stated that the dam would be paid for energy production.

part of the dam is also involved in the flood check. It reduces the number of main flood floods from once every 10 years to once every 100 years. Its massive tank of 22 cubic kilometers will regulate the flow of water, increases during large floods and releases water at unmíra ryform, saves people downstream from the destructive economic effects of floods. The Three Gorges dam will be 200 m deep (219 yards) when it is fully flooded.
