What is the future of the Three Gorges Dam?
The Three Gorges Dam is projected as an anchor in a string of hydropower “mega-bases” planned for the middle and upper reaches of the Yangtze River. By 2020, China wants to nearly triple its hydropower capacity, to 300 gigawatts.
Is Three Gorges Dam Reduce Earth Rotation?
When the Three Gorges Dam was built, 39 trillion kilograms of water from the Yangtze River built up behind it to 175 meters above sea level. This altered the Earth’s moment of inertia changed ever so slightly, causing the rotation to move more slowly.
What are 2 positive results of the Three Gorges Dam?
On one hand, the benefits of the Three Gorges Dam are flood control, power generation, navigation, aquaculture, tourism, ecological protection, environmental purification, development-oriented resettlement, transfer of water from southern China to northern China, and water supply and irrigation.
Why is the 3 Gorges dam good?
As well as producing electricity, the dam is intended to increase the Yangtze River’s shipping capacity. By providing flood storage space, the dam reduces the potential for floods downstream which have historically plagued the Yangtze Plain. In 1931, floods on the river caused the deaths of up to 4 million people.
What is the negative side of the Three Gorges Dam?
The disadvantage of the Three Gorges Dam is that there are sedimentation and erosion hazards that are associated with the project. About 80% of the land area around the dam is experiencing problems with erosion, which produces over 40 million tons of sediment that is deposited into the river each year.
