Landscape and Cultural Heritage: After the impoundment of the reservoir, higher water level and wider channel would change the scenery of the canyon to a certain extent' The elevations of mountains and peaks along the banks in the gorges range from to 1, m in nature.
The elevations of the famous 12 peaks in Wuxi a Gorge are around 1, m. The most reputed Goddess Peak is more than m above sea level. The normal pool level of the reservoir at m will result in an increase of 40 to m higher in the Gorges than at present. So the steep canyon enclosing the river valley will be basically untouched, even though the rapids and dangerous shoals will be eliminated. Better navigation condition will provide access to new scenic views, for instance, the Lesser Three Gorges " along the Daning River' The magnificent Three Gorges Project shall certainly become a new hot spot of tourism.
Environment : Dam defenders point to the environmental benefits given by the dam, such as the availability of hydroelectric power, which is much cleaner than the coal burning China has relied heavily for decades. They believe the dam will reduce greenhouse gas emissions by reducing coal burning thereby protecting the ozone layer and have none of the radiation hazards at nuclear plants. The world's largest water conservancy project with the biggest flood-control capability.
The total storage capacity of the reservoir is The total installed capacity of the Three Gorges Hydropower Station is 18, MW with an annual electricity output of The world's largest water conservancy project with the world's largest project building scale. The total length of the dam axis is The spillway section, which is located in the middle of the river course,is meters long in total.
There are 26 sets of turbine generator units in total, MW for each. The shiplock is schemed out as a double-way and five-step lock.
It is the world's largest water conservancy project with the world's largest project building scale. If passengers want to experience how the ship cross the dam, take the optional tour of ship lock experience is a good choice.
The ship lift an optional tour of Yangtze River Cruises. On both upstream day 2 and downstream day 4 , passengers will disembark, and take a specially-designed sightseeing boat through the ship lock lift. A visit to the Three Gorges Dam will follow.
Then the cruise companies provide land transfers between Yichang and Maoping in both directions for embarking and disembarking passengers. Under construction since and completed last November, the ship lock lift is the final component in the Three Gorges Dam complex.
It is the largest of its kind in the world, capable of lifting ships of up to 3, tons. It is nearly the height of a story building, with a water volume equivalent to 4 Olympic swimming pools. The World Bank, stung by vicious criticism of other hydro projects it sponsored, decided not to fund the project.
It hoped to gain further environmental information from the Chinese, which would allow for a positive decision. It was not against the project. Moreover, its stance did not prevent US groups from bidding for contracts, nor US commercial banks from financing their operations. Ecology and environmental monitoring information system for the project was opened in Fish Nurturing Centre Base was also built for the conservation of Asian carp and other species through the eco-scheduling process.
European governments snubbed Three Gorges opponents. The export credit agencies of Germany, Switzerland, Sweden, France and the UK all promised support for potential suppliers from their countries. Japan, after initial hesitation, followed their lead. Canada also offered financing to its companies. Long-term commercial loans by banks in these countries supported the credits.
After intensive reviews by the Japanese Ministry of International Trade and Industry, Japan claimed the project offered the following main benefits:. Flood control: Japan believed the project would achieve its objectives in the area, despite claims that it could actually increase the risk of floods, either through changes in silt flow or a catastrophic dam collapse.
This issue, in particular, generated a lot of sympathy for the project in Japan. If it is not built, soaring Chinese emissions would rise even faster, causing more acid rain in Japan. Relocation: Japan believes current plans are adequate, although the situation would need to be kept under review. China initially insisted that potential problems were identified and dealt with.
However, there were calls on Western governments and companies to refrain from further support of the project until resettlement and human rights problems were resolved. There were claims that the dam did not address the real source of flooding deforestation in the Yangtze watershed and the loss of lakes that alleviated floods because of siltation, reclamation and uncontrolled development.
Corruption scandals also plagued the project. Contractors allegedly won bids through bribery and then siphoned off construction funds by skimping on equipment and materials. Other concerns include decreasing sediment levels downstream, which could affect banks downstream and make cities prone to flooding. Finally, there is concern that relics could be lost in the flood area.
Many of these relics and sites have been moved or copied to other locations. There are some huge positive impacts that come with the dam. Most importantly, the dam significantly reduces the risk of flooding downstream and protects millions of people from risk of large-scale flooding.
This huge advancement is one of the key selling points of the dam, and something that has been spoken of since Mao Zedong. Some people were relocated in neighboring towns or cities, while more people had to move to other parts of China, including Sichuan, Jiangsu, Zhejiang, Shandong, Guangdong, Shanghai, Fujian, Anhui, Jiangxi and Hunan provinces. Problems Caused by Three Gorges Dam. It is not easy to dam the Yangtze River because of very large volume of runoff and quite wide inundated area.
In the beginning, a cofferdam was built on the right bank, at the same time, temporary and permanent ship locks were constructed on the left bank. When the temporary ship lock was finished, the second river closure began.
The cofferdam in right bank was dismantled and the main stream of Yangtze River was cut off, where the spillway and left hydroelectric dam body were constructed. After these constructions were done, the cofferdam in main stream was dismantled and another cofferdam was built on right bank again.
When the right hydroelectric dam body was constructed, the cofferdam was removed. In such a complex method, the construction of magnificent Three Gorges Dam was finished. Answers App. Three Gorges Dam is the main part of Three Gorges Hydropower Station, the largest hydropower project in the world, which created multiple records on construction, scale, comprehensive efficiency and other aspects.
