This is particularly detrimental to the ecosystem of the region because the Yangtze River basin is home to different fish species and accounts for twenty-seven percent of all endangered freshwater fish species in China.
As a result, damage to an individual section should not affect other parts of the dam.
Three Gorges Dam is 2,m in length and m in height, and the project started from December 14th,and it's completed and fully functional as of July 4th, except for a ship lift, which was completed in December The dam will reduce the impacts of flooding since it will have a flood control capacity of The landslide buried a bus, killing at least 30 people.
But in September, the government official in charge of the project admitted that Three Gorges held "hidden dangers" that could breed disaster. When construction of the dam officially began init was the largest engineering project in China.
The dam is feet high and 1. Disease and Drought When officials unveiled plans for the dam, they touted its ability to prevent floods downstream.
There were also fears—some of which were borne out—that human and industrial waste from cities would pollute the reservoir and even that the huge amount of water impounded in the reservoir could trigger earthquakes and landslides.
This is particularly detrimental to the ecosystem of the region because the Yangtze River basin is home to different fish species and accounts for twenty-seven percent of all endangered freshwater fish species in China. Medical Center in Washington, D. The result is a narrow lake miles kilometers long—60 miles 97 kilometers longer than Lake Superior—and 3, feet 1, meters wide, twice the width of the natural river channel.
See Article History Alternative Title: It is 3, miles long with an annual discharge of billion cubic meters of water into the East China Sea. According to Davis, such alterations could precipitate a rise in other microbial waterborne diseases as well.
Surveys show that the Three Gorges region may be next.
Even fully operational, on average, it supports only about 1. However, electricity demand has increased more quickly than previously projected. It is located in the middle of the tree gorges on the Yangtze River, the third longest in the world, in the Hubei Province of China.
But last fall, denial suddenly gave way to reluctant acceptance that the naysayers were right. The Three Gorges Dam is the largest hydroelectric dam in the world. The moving mass including counterweights is 34, tonnes.
As of Maythe ship lift was expected to be completed by July The snails used to breed on small flood plain islands where annual flooding prevented a population explosion.
The Three Gorges Dam will produce about It is home to 6, species of plants, which belong to families and genera. Tourists can not only watch the magnificent dam, but also see the Three Gorges Dam Ship Locks — the five-level Ship Locks is the largest ship locks in the world.

A straight-crested concrete gravity structure, the Three Gorges Dam is 2, metres (7, feet) long with a maximum height of metres ( feet).
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, China.
The Three Gorges Dam is the world's largest power station in terms of installed capacity (22, MW). The Big Dams Debate: The Environmental Sustainability Challenge for Dam Engineers / The Three Gorges Project: Key to the Development of the Yangtze River / The Limited Benefits of Flood Control - Lu Qinkan (Civil Engineering Practice, Volume 12, Number 1).
The Three Gorges Dam project will require the resettlement of million people, according to the government, although observers say that estimate may be short by as many aspeople. The project will flood the three gorges that give the dam its name: the Qutang, Wu Xia, and Xiling.
They stretch for some miles ( kilometers) along the. The Three Gorges Dam is the largest hydroelectric dam in the world. It is located in the middle of the tree gorges on the Yangtze River, the third longest in the world, in the Hubei Province of China.Download
