The '''Three Gorges Dam''' ({{zh-stp|s={{linktext|长|江|三|峡|大|坝}}|t={{linktext|長|江|三|峽|大|壩}}|p={{linktext|Cháng|jiāng| Sān|xiá| Dà|bà}}}}) is a [[hydroelectricity|hydroelectric]] [[river]] [[dam]] that spans the [[Yangtze River]] ({{zh-cp|c={{linktext|扬|/|洋|子}}|p={{linktext|Yáng|zǐ}}}}) in [[Sandouping]], [[Yichang]], [[Hubei]], China. It is the [[List of the largest hydroelectric power stations|largest hydroelectric power station]] in the world. Except for a planned ship lift, all the original plan of the project was completed on October 30, 2008, when the 26th [[Electrical generator|generator]] was brought to commercial operation.<ref name="ctgpc1">{{cite web|url=http://www.ctgpc.com.cn/sx/news.php?mNewsId=30559 |title=三峡工程左右岸电站26台机组全部投入商业运行 |language=Chinese |publisher=China Three Gorges Project Corporation |date=2008-10-30 |accessdate=2008-12-06}}</ref> |

As with many dams, there is a debate over costs and benefits. Although there are economic benefits such as [[flood]] control, clean hydroelectricity and navigation, there are also concerns about the relocation of people, [[siltation]], loss of [[archaeological]] and cultural sites and the impact on regional ecosystem.<ref name="aljazeera">{{cite news | publisher = Aljazeera | author = Tony Cheng | url=http://www.segabg.com/online/article.asp?issueid=1185§ionid=1&id=00001 | title=Bitter memories above the Yangtze | date=[[2007-12-09]] | accessdate=2008-01-20 }}</ref> |

==Project history== |
|||
[[Image:Wuhan-Flood-Memorial-0220.jpg|thumb|left|In his poem "Swimming" (1956), engraved on the [[1954 Yangtze River Floods|1954 Flood]] Memorial in [[Wuhan]], Mao Zedong envisions "walls of stone" to be erected upstream.<ref>[http://www.marxists.org/reference/archive/mao/selected-works/poems/poems23.htm "Swimming" by Mao Zedong]</ref>]] |
|||
The dam was originally envisioned by [[Sun Yat-sen]] in ''The International Development of China'' in 1919.<ref name="culturemall"/> In 1932 the Nationalist government, led by [[Chiang Kai-shek]], began preliminary work on plans for a dam in the [[Three Gorges]]. Then in 1939 the Japanese military forces occupied Yichang and surveyed the area. A design, the Otani plan, was completed for the dam in anticipation of a Japanese victory over China.<ref>[http://www.china.org.cn/chinese/zhuanti/sanxia/337524.htm ]{{Dead link|date=December 2008}}</ref> In 1944 involvement from the United States began when the [[Bureau of Reclamation]] engineer [[J.L. Savage]] surveyed the area and drew up a dam proposal. Around 54 Chinese engineers were sent to the U.S. for training. Some exploration, survey, economic study, and design work was done, but the government, in the midst of the [[Chinese Civil War]], halted work in 1947.<ref name="schiller">{{cite news | publisher = Schiller Institute | author = William C.

|||
After the 1949 communist victory, the leader [[Mao Zedong]] supported the project, but the [[Gezhouba Dam]] project was begun first and economic problems including the [[Great Leap Forward]] and the [[Cultural Revolution]] slowed progress. In 1958, after the [[Hundred Flowers Campaign]], some engineers who spoke out against the project were imprisoned.<ref name="WPhist">{{cite news | publisher = Washington Post | author = Steven Mufson | url=http://www.washingtonpost.com/wp-srv/inatl/longterm/yangtze/yangtze.htm | title= The Yangtze Dam: Feat or Folly? | date=1997-11-09 | accessdate=2008-01-20 }}</ref> |
|||
During the 1980s plans were revived. Pushed through by [[Li Peng]], the dam was approved by the [[National People's Congress]] in 1992 with a record number of abstentions and dissenting votes. {{Fact|date=August 2008}} The construction started on December 14, 1994.<ref name="allin"> |

When finished, the project will have cost 180 billion yuan, over 20 billion yuan less than the initial estimated budget of 203.9 billion yuan, just under 30 billion USD.

Sources for funding include the Three Gorges Dam Construction Fund, profits from the [[Gezhouba Dam]], policy loans from the [[China Development Bank]], loans from domestic and foreign commercial banks, [[corporate bond]]s, and revenue from Three Gorges Dam before and after it is fully operational, with additional charges for electricity contributing to the Three Gorges Construction Fund. The additional charges are as follows: Every province receiving power from the Three Gorges Dam has to pay an additional charge of ¥7.00 per MWh. Provinces that will not receive power from the Three Gorges Dam have to pay an additional charge of ¥4.00 per MWh. Tibet does not have to pay any additional money.<ref>{{cite news |

Each of the main generators weighs about 6000 tonnes and are designed to produce at least 700 MW of power. The designed head of the generator is 80.6 m. The flow rate varies between 600 m<sup>3</sup>/s to 950 m<sup>3</sup>/s depending on the head available. The Three Gorges Dam project installs [[Francis turbine]]s. The diameter of the turbine is 9.7/10.4 m (VGS design/Alstom's design). It rotates at a speed of 75 rpm. The normal rated power of the generator is 778 [[Volt ampere|MVA]]. The maximum power is 840 MVA. The [[power factor]] is 0.9. The generator produces electrical power at 20 [[Volt|kV]]. The outer diameter of the generator stator is 21.4/20.9 m. The inner diameter is 18.5/18.8 m. The height of the stator is 3.1/3 m. It is the biggest stator in the world. The load at the bearing is 5050/5500 tonnes. The average efficiency of the generators is over 94%, and the highest is 96.5%.<ref>{{cite web|url=http://news.xinhuanet.com/fortune/2008-08/28/content_9723523_2.htm |title=李永安:我水轮发电机组已具完全自主设计制造能力_财经频道_新华网 |language=Chinese |publisher=xinhuanet.com |date=2008-08-28 |accessdate=2008-12-06}}</ref> |

The generators are manufactured by two joint ventures. One of them includes [[Alstom]], [[ABB]], [[Kvaerner]] and the Chinese company Haerbin Motor. The other includes [[Voith]], [[General Electric]], [[Siemens]] (abbreviated as VGS), and the Chinese company Oriental Motor. The technology transfer agreement was signed together with the contract. More than 8 of the 32 generators are made in China. Most of the generators are water-cooled. Some newer ones are air-cooled, which are simpler in design,manufacture and easier to maintain.<ref name=Chinacom20020726> |

The electricity generated by the Three Gorges Dam project was sold to the [[State Grid Corporation]] and [[China Southern Power Grid]] at a flat rate of ¥250 per MWh ($35.7 US) until July 2, 2008. The price of electricity now is different depending on which province is sold to, ranging from ¥230.6 per MWh to ¥311.1 per MWh.<ref>[http://www.ctgpc.com.cn/sx/news.php?mNewsId=29096 中国长江三峡工程开发总公司<!-- Bot generated title -->]</ref> Nine provinces and two cities consume the power from it, including Shanghai.<ref name="chinagate">{{cite news |

Power is sent in three directions. The 500 kV DC transmission line to the East China Grid has a capacity of 7,200 MW. There are three 500 kV DC transmission lines: [[HVDC Three Gorges-Shanghai]] (3,000 MW), [[HVDC Three Gorges-Changzhou]] (3,000 MW) and [[HVDC Gezhouba - Shanghai]] (1,200 MW). The 500 kV AC transmission line to Central China Grid has a capacity of 12,000 MW. The other 500 kV DC transmission line [[HVDC Three Gorges-Guangdong]] to South China Grid has a capacity of 3,000 MW and supplies [[Guangdong]].<ref name="abb">{{cite web |

===Reduction of greenhouse gas due to navigation=== |
|||
From 2004 to 2007 a total of 198 million tonnes of goods passed through the Three Gorges Dam ship locks. The freight capacity of the river increased 6 times and the cost of shipping reduced by 25%, compared to previous years, which reduces carbon dioxide emission by 630,000 tonnes. Comparing to highway transportation, the amount of fuel that Three Gorges Dam project saved between the year of 2004 and 2007 is equivalent to 4,100,000 tonnes of standard coal. Thus it reduces carbon dioxide emission by 10 million tonnes.<ref name=Xinhuar2007023/> |
|||
===Waste management=== |
|||
Since the construction of the Three Gorges Dam, many waste water treatment plants have been completed to reduce the water pollution from the large populated city Chongqing and the suburban area around it. According to the ministry of environmental protection of PRC, until April 2007, there were more than 50 waste water treatment plants installed and the total capacity reached 1.84 million tonnes per day. More than 65% of the waste water is treated before being dumped into the Three Gorges Dam reservoir. About 32 land sites deposit were completed and could handle 7664.5 tonnes of solid waste every day.<ref name=Zhb20070419> |

===Reforestation=== |
|||
The Three Gorges Dam pushes the Chinese government to think seriously about the environmental issues associated with the dam, such as deforestation and water pollution. {{Fact|date=July 2008}} “The FAO’s research suggests that the Asia-Pacific region will, overall, gain about 6,000 square km of forest in 2008. That is quite a turnaround from the 13,000 square km net loss of forest each year in the 1990s. The main reason is China’s huge reforestation effort. This accelerated after terrible floods in 1998 convinced the government that it must restore tree cover, especially in the mighty Yangtze’s basin” upstream of the Three Gorges Dam.<ref>Peter Collins "Falling here, rising there" Page 63,The World in 2008,The Economist</ref> |
|||
==Flood control and drought relief== |
|||
The most significant function of the dam is to control flooding, which is a major problem of a seasonal river like the Yangtze. Millions of people live downstream of the dam, and many large and important cities like [[Wuhan]], [[Nanjing]] and Shanghai lie next to the river. Plenty of farm land and the most important industrial area of China are built beside the river.<br /> |
|||
The reservoir's flood storage capacity is 22 km<sup>3</sup>(18 million [[acre-foot|acre feet]]). This capacity will reduce the frequency of major downstream [[flood]]ing from once every 10 years to once every 100 years. With the dam, it is expected that major floods can be controlled. If a "super" flood comes, the dam is expected to minimize its effect.<ref name="culturemall"/> |
|||
[[1954 Yangtze River Floods|In 1954 the river flooded]] {{convert|193000|km2|sqmi|0|abbr=on}} of land, killing 33,169 people and forcing 18,884,000 people to move. The flood covered [[Wuhan]], a city with 8 million people, for over three months, and the [[Jingguang Railway]] was out of service for more than 100 days.<ref name="culturemall"/> In the event of a recurrence of the 1954 flood that carried 50 billion m<sup>3</sup> of water, the Three Gorges Dam could only divert the water above Chenglingji, still leaving 30 to 40 billion m<sup>3</sup> of flood water to be diverted.<ref>Dai, Qing. Yangtze! Yangtze!. UK: Earthscan Ltd, 1994., 184</ref> Also the dam will not protect the large tributaries such as the Xiangjiang, Zishui, [[Yuan River|Yuanshui]], Lishui, Hanjiang, and Ganjiang from flooding, due to the location of the dam. |
|||
[[1998 Yangtze River Floods|In 1998 a flood in the same area]] caused billions of dollars in damage. The Chinese government asked for support from its military to fight the flooding. 2039 square kilometers of farm land was flooded. The flood affected more than 2.3 million people, and 1,526 were killed.<ref>{{cite news |

The Dam discharges its reservoir during the dry season between December and March every year.<ref>http://www.gov.cn/jrzg/2009-02/18/content_1235518.htm</ref> This increases the flow rate of the river downstream, and provides more fresh water for agricultural and industrial usage. It also improves the navigation conditions during dry season. The water level upstream drops from 175 m to 145 m,<ref>http://www.hb.xinhuanet.com/zhibo/2009-02/19/content_15732434.htm</ref> leaving room for the flooding season.

The installation of [[lock (water transport)|ship locks]] is intended to increase river shipping from 10 million to 100 million [[tonne]]s annually, with transportation costs cut by 30 to 37%.

There have been accusations of corruption over money sent to the town of Gaoyang for the purpose of relocation for 13,000 farmers. The money disappeared after it was sent to the local government, and residents were denied compensation.<ref name="nationalgeographic">{{cite news | url=http://news.bbc.co.uk/2/hi/asia-pacific/1925172.stm |

Of the 3,000 to 4,000 remaining [[critically endangered]] [[Siberian Crane]], a large number currently spend the winter in wetlands that will be destroyed by the Three Gorges Dam. The dam also contributed to the functional extinction of the [[Baiji]], the Yangtze river dolphin. In addition, populations of the [[Yangtze sturgeon]] are guaranteed to be "negatively affected" by the dam. |
|||
There are high levels of pollution currently in the [[Yangtze]]. Over one billion tons of wastewater are released annually into the river.<ref name="autogenerated1">Qing, Dai, 9. The River Dragon Has Come!: The Three Gorges Dam and the Fate of China's Yangtze River and Its People (East Gate Book). Armonk, New York: M.E. Sharpe, 1997.</ref> The dam will significantly decrease the river's flushing capacity and the pollution ratings will increase. For the current amount of pollution, there is an estimated cost of 2.8 billion [[Renminbi|Yuan]] to clean the river{{Facts|date=May 2008}}. |
|||
While logging in the area was required for construction {{Facts|date=May 2008}}which adds to erosion, stopping the periodic and uncontrolled flooding of the river will lessen bank erosion in the long run. The build up of silt in the reservoir will, however, reduce the amount of silt transported by the Yangtze River to the Yangtze Delta and could reduce the effectiveness of the dam for electricity generation and, perhaps more importantly, the lack of silt deposited in the peninsula could result in erosion and sinking of coastal areas. |
|||
===Effect on local culture and aesthetic values=== |
|||
The 600 kilometer (375 mi) long reservoir has flooded or will flood some 1,300 archaeological sites and will alter the appearance of the Three Gorges as the water level rises over one hundred meters at various locations.<ref>{{cite news |

===Sedimentation=== |
|||
There are two hazards uniquely identified with the dam.<ref>Topping, Audrey Ronning. Environmental controversy over the Three Gorges Dam. Earth Times News Service.</ref> One is that sedimentation projections are not agreed upon, and the other is that the dam sits on a seismic fault. |
|||
The [[Three Gorges]] area currently has 10% forestation, down from 20% in the 1950s. At current levels 80% of the land in the area is experiencing erosion causing about 40 million tons of sediment to slide into the [[Yangtze]] annually.<ref name="autogenerated1" /> The relocation of people from the reservoir area will cause further deforestation and erosion due to agricultural needs. |
|||
Excessive sedimentation can block the sluice gates which can cause dam failure under some conditions. This was a contributing cause of the [[Banqiao Dam]] failure in 1975 that precipitated the failure of 61 other dams and resulted in over 20,000 deaths. Critics believe that the [[Yangtze]] will add 530 million tons of [[silt]] into the reservoir on average per year; in time, this silt could accumulate behind the walls of the dam, clogging the [[turbines]]' entranceway. However, because China has begun constructing four other megadams (see below) on the upstream of Yangtze since 2006, the sedimentation from upstream would be much less than originally predicted. But the absence of silt down stream would still have two dramatic effects: |
|||
* Some hydrologists think that this could make downstream riverbanks more vulnerable to flooding.{{Fact|date=March 2008}} |
|||
* The city of Shanghai, more than one thousand miles (1600 km) away from the dam, rests on a massive plain of [[sediment]]. The ''"arriving silt -- so long as it does arrive -- strengthens the bed on which Shanghai is built... the less the tonnage of arriving sediment the more vulnerable is this biggest of Chinese cities to inundation..."''<ref>{{cite book |

In an annual report to the [[United States Congress]], the [[United States Department of the Defense|Department of Defense]] cited that in Taiwan, “proponents of strikes against the mainland apparently hope that merely presenting credible threats to China’s urban population or high-value targets, such as the Three Gorges Dam, will deter Chinese military coercion.”<ref>{{cite web |

The notion that the [[Military of the Republic of China]] would seek to destroy the Dam provoked an angry response from the [[mainland China]] media. [[People's Liberation Army|People’s Liberation Army]] [[General Liu Yuan]] was quoted in the ''[[China Youth Daily]]'' saying that the People’s Republic of China would be "seriously on guard against threats from [[Taiwan independence]] terrorists".<ref>{{cite news |

==Future projects upstream== |
|||
In order to maximize the utility of the Three Gorges Dam and cut down on sedimentation from the [[Jinsha]], a tributary of the Yangtze river, China plans to build a series of dams upstream of the Yangtze river, including [[Wudongde Dam]], [[Baihetan Dam]], [[Xiluodu Dam]], [[Xiangjiaba Dam]], and downstream of [[Jinsha]]. The total capacity of those four dams is 38,500 MW,<ref>[http://www.chinapower.com.cn/newsarticle/1008/new1008554.asp 中国三峡总公司拟在金沙江上建4座梯级水电站 总装机容量为3850万千瓦_中国电力网(www.chinapower.com.cn)新闻中心<!-- Bot generated title -->]</ref> almost double the capacity of the Three Gorges.<ref>{{cite news |

==References in culture== |

* In [[Max Brooks]]’ novel ''[[World War Z]]'', the large artificial lake upstream of the dam is the site of the initial [[zombie]] outbreak before the war; a superstitious character suggests that the outbreak is a retribution for the destruction of ancient holy sites. Later in the novel, the Dam is overrun by zombie hordes, which make the emergency pressure release valves impossible to reach. This eventually results in the Three Gorges Dam rupturing, resulting in a massive tsunami which races to the ocean, destroying what remains of Wuhan, Nanjing, and Shanghai. This results in the outbreak of the Chinese Civil War.<ref>Matthew S. Muller. Amazon.com review of ''World War Z: An Oral History of the Zombie War''.</ref><ref name="culturemall"/> |
