// Load the SDK asynchronously [16][122] Lahmeyer, the German firm that designed the ship lift, said it will take a vessel less than an hour to transit the lift. [126] The 95-kilometre (59 mi) long southern portage railway (南岸翻坝铁路) will run from Maoping (upstream of the dam) via Yichang South Railway Station to Zhicheng (on the Jiaozuo–Liuzhou Railway). From 2003 to 2007, power production equaled that of 84 million tonnes of standard coal.[83]. In 1958, after the Hundred Flowers Campaign, some engineers who spoke out against the project were imprisoned. The technology transfer agreement was signed together with the contract. [123] It says that the expected dimensions of the 3,000 tonnes (3,000,000 kg) passenger vessels the ship lift's basin was designed to carry will be 84.5 by 17.2 by 2.65 metres (277.2 ft × 56.4 ft × 8.7 ft). view more headlines . The dam limited the water flow to less than 40,000 cubic metres (1,400,000 cu ft) per second, raising the upstream water level from 145.13 m (476.1 ft) on August 1, 2009, to 152.88 m (501.6 ft) on August 8, 2009. The ship lift can lift ships of up to 3,000 tons. From 2004 to 2007, a total of 198 million tonnes of freight passed through the locks. Huang predicted numerous negative consequences should the Three Gorges Dam be built, including the collapse … fjs.parentNode.insertBefore(js, fjs); The total capacity of the ship locks is expected to reach 100 million tonnes per year.[83]. Watch later. It contains 39.3 km3 (31,900,000 acre⋅ft) of water and has a total surface area of 1,045 km2 (403 sq mi). This is particularly detrimental to the ecosystem of the region because the Yangtze River basin is home to 361 different fish species and accounts for 27 percent of all endangered freshwater fish species in China. [96] Other aquatic species have been endangered by the dam, particularly the baiji, or Chinese river dolphin,[85] now extinct. Maximum vessel size is 10,000 tons. Groups of craft would be lifted together for efficiency. Shopping. Shipping will become safer, since the gorges are notoriously dangerous to navigate. Then in 2018 it was reported online that pictures show that the Three Gorges Dam has moved: An expert on the region’s … [140], The United States Department of Defense reported 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. As many as 400 million people may be at risk, however, local media Global Times said experts have dismissed reports that the dam is at a brink of collapse. [85] Because the flow is slower above the dam, much of this sediment will now settle there instead of flowing downstream, and there will be less sediment downstream. The NTD link in the OP claims that the Three Gorges Dam is not properly anchored to the bedrock, and satellite photos show that portions of the dam appear to have moved in response to water pressure. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. var js, fjs = d.getElementsByTagName(s)[0]; Last week we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. [108], During the 2010 South China floods in July, inflows at the Three Gorges Dam reached a peak of 70,000 m3/s (2,500,000 cu ft/s), exceeding the peak during the 1998 Yangtze River Floods. A sudden collapse of the dam could release a wall of water over a hundred feet high with 400 million people living in the valley downstream. Each main water turbine has a capacity of 700 MW. According to the Changjiang Ministry of Water Resources, both the Gezhou Dam and the Three Gorges Dam stopped 30 billion cubic meters of floodwater during the last 30-days. [16], As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity. [149] Baihetan is under construction and Wudongde is seeking government approval. [citation needed]. [37] It has a combined generating capacity of 22.5 gigawatts and a designed annual generation capacity of 88.2 billion kilowatt hours. The moving mass (including counterweights) is 34,000 tonnes. [104] Also, the dam cannot protect against some of the large tributaries downstream, including the Xiang, Zishui, Yuanshui, Lishui, Hanshui, and the Gan. In November 2007, it was reported in the local media that construction of the ship lift started in October 2007. On the flipside, the dam is holding back energy equivalent to several hundred nuclear bombs, and contains enough water to wipe out the entirety of Hubei province were it to collapse. [31], During the 1980s, the idea of a dam reemerged. That is a significant change from the 13,000 km2 (5,000 sq mi) net loss of forest each year in the 1990s. js.src = "https://connect.facebook.net/en_US/sdk.js"; [73][74], The Three Gorges Dam reached its design-maximum reservoir water level of 175 m (574 ft) for the first time on October 26, 2010, in which the intended annual power-generation capacity of 84.7 TWh was realized. [68][69] In July 2008 it generated 10.3 TWh of electricity, its first month over 10 TWh. If playback doesn't begin shortly, try restarting your device. [103] The 1954 flood carried 50 cubic kilometres (12 cu mi) of water. [128] As of June 2008, China relocated 1.24 million residents (ending with Gaoyang in Hubei Province) as 13 cities, 140 towns and 1350 villages either flooded or were partially flooded by the reservoir,[129][130][131] about 1.5% of the province's 60.3 million and Chongqing Municipality's 31.44 million population. From 2003 to 2007, power production equaled that of 84 million tonnes of standard coal. [46][47], The generators were manufactured by two joint ventures: one of them Alstom, ABB Group, Kvaerner, and the Chinese company Harbin Motor; the other Voith, General Electric, Siemens (abbreviated as VGS), and the Chinese company Oriental Motor. [97] The Chinese paddlefish is also believed extinct in part due to the dam blocking its migration. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. Some newer ones are air-cooled, which are simpler in design and manufacture and are easier to maintain. The company noted that parts of the dam had “deformed slightly,” displacing some external structures, and seepage into the main outlet walls had also been reported throughout the 18 hours on Saturday and Sunday when water was discharged though its outlets. The Three Gorges Dam is rapidly failing. [80][81], According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. Copy link. Full power (9,800 MW) was only reached on October 18, 2006, after the water level reached 156 m.[49], The 12 south side main generators are also in operation. 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 Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River by the town of Sandouping, in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. };
The 88-kilometre (55 mi) long northern portage railway (北岸翻坝铁路) will run from the Taipingxi port facility (太平溪港) on the northern side of the Yangtze, just upstream from the dam, via Yichang East Railway Station to the Baiyang Tianjiahe port facility in Baiyang Town (白洋镇), below Yichang. [42] It was estimated in 2009 that the construction cost would be recovered when the dam had generated 1,000 terawatt-hours (3,600 PJ) of electricity, yielding 250 billion yuan. [12][13] Coupling the dam's 32 main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW. Of these plant species, 57 percent are endangered. cookie : true, // enable cookies to allow the server to access [94] These rare species are also used as ingredients in traditional Chinese medicines. TRENDING: Photo Appears to Show Black Lives Matter Supporters Holding Down and Kneeling on Neck of White Baby. In a rare revelation, Beijing has admitted that its 2.4-kilometer Three Gorges Dam spanning the Yangtze River in Hubei province “deformed slightly” after record flooding. [43], Funding sources include the Three Gorges Dam Construction Fund, profits from the Gezhouba Dam, loans from the China Development Bank, loans from domestic and foreign commercial banks, corporate bonds, and revenue from both before and after the dam is fully operational. appId : "", A flood alert has been raised near Three Gorges Dam in China-- the largest hydropower project in the world-- as the country grapples with its worst flooding in 70 years. [7] After the extensive monsoon rainfalls of 2020, the dam's annual production reached ~112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016. The Three Gorges dam is discharging flood. [16][114] The vertical distance traveled is 113 m (371 ft),[115] and the size of the ship lift's basin is 120 m × 18 m × 3.5 m (394 ft × 59 ft × 11 ft). …Zhang Jianping, an activist in Jiangsu, is skeptical. A substitute teacher at Bok Academy in Lake Wales, Florida was fired, The House in Washington State is proposing a law to make elections, Opinion: Masters of the Universe Tell Stalin to, “Hold My Beer.” Source, I’m surprised. And that if it fails, it would kill millions of people, perhaps 100 million according to some claims, and displace even more. [29] Some 54 Chinese engineers went to the U.S. for training. [48], The first north side main generator (No. The dam has come under new scrutiny after devastating flooding over the past few weeks. The flood covered Wuhan, a city of eight million people, for over three months, and the Jingguang Railway was out of service for more than 100 days. All other rights are reserved for The Spectator Media, unless otherwise noted. The deformation occurred last Saturday when the flood from western provinces including Sichuan and Chongqing along the upper reaches of the Yangtze River peaked at a record-setting 61,000 cubic meters per second, according to China Three Gorges Corporation, a state-owned enterprise that manages the dam and the sprawling power plant underneath it. Concerns about the potential wildlife impact of the dam predate the National People's Congress's approval in 1992. A design, the Otani plan, was completed for the dam in anticipation of a Japanese victory over China. Scientist Wang Weiluo said that the Three Gorges Dam was not as stable as many people thought. [94] Freshwater fish are especially affected by dams due to changes in the water temperature and flow regime. Torrential rains have been causing havoc throughout the southwest and central region this month, with many rivers bursting their banks, prompting mass evacuations. [105] In early August 2009, the largest flood in five years passed through the dam site. The greater the head, the less water needed to reach full power. [90], The dam catalyzed improved upstream wastewater treatment around Chongqing and its suburban areas. Model of the Three Gorges Dam showing the ship lift and the ship lock. Without soybeans from Brazil and the USA and wheat from Australia and Europe and the US, China cannot feed its livestock let alone its human population. [27][28] He stated that a dam capable of generating 30 million horsepower (22 GW) was possible downstream of the Three Gorges. Many other fish are injured in the turbine blades of the hydroelectric plants as well. China regards the project as a monumental social and economical success,[17] with the design of state-of-the-art large turbines,[18] and a move toward limiting greenhouse gas emissions. “Since it was built, it has never played a role in preventing flooding or droughts, like we thought it would back then.”. js = d.createElement(s); js.id = id; The generator produces electrical power at 20 kV. 17) began operation on December 18, 2007, raising capacity to 14.1 GW, finally surpassing Itaipu dam (14.0 GW), to become the world's largest hydro power plant by capacity. In 1998, a flood in the same area caused billions of dollars in damage; 2,039 km2 (787 sq mi) of farmland were flooded. Three Gorges Dam sets power generation record in 2020 China.org.cn 01:34 2-Jan-21. The water also powers the Gezhouba Dam downstream. A conservative publication and syndicator with one aspiration to fulfill: a media platform where truth conquers all. September 7, 2020 by IWB. [76] Nine provinces and two cities consume power from the dam. [130] Some 2007 reports claimed that Chongqing Municipality will encourage an additional four million people to move away from the dam to the main urban area of Chongqing by 2020. This accelerated after the 1998 Yangtze River floods convinced the government that it should restore tree cover, especially in the Yangtze's basin upstream of the Three Gorges Dam.[92]. However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. [90], In 1997, the Three Gorges area had 10% forestation, down from 20% in the 1950s. The flood affected more than 2.3 million people, killing 1,526. [139] Cultural and historical relics are being moved to higher ground as they are discovered, but the flooding inevitably covered undiscovered relics. The problem is that China once claimed the dam would withstand a 10,000 year flood, then a 1,000 year flood and now only a 100 year flood. Though the "distortion" later proved to be caused by low resolution of the image, the "deformation and collapse prediction" continued to circulate. [19] However, the dam flooded archaeological and cultural sites, displaced some 1.3 million people, and had caused significant ecological changes including an increased risk of landslides. Tap to … However, damage to the entire dam through means such as missiles could cause flooding along a large area of the Yangtze River due to overflow spillage.[143]. [15][31][35] The ship lift was completed in 2015. [116] One complicating factor is that the water level can vary dramatically. The flow rate varies between 600–950 cubic metres per second (21,000–34,000 cu ft/s) depending on the head available. [85], Research by the United Nations Food and Agriculture Organization suggested that the Asia-Pacific region would, overall, gain about 6,000 km2 (2,300 sq mi) of forest by 2008. Completely interpretation their picture within the Tv set play, the eternally Piaget duplicate wrist watches with. Made of concrete and steel, the dam is 2,335 m (7,661 ft) long and the top of the dam is 185 m (607 ft) above sea level. Please update this article to reflect recent events or newly available information. Even before construction of the Three Gorges Dam began in 1994, many experts were already criticizing the project. Building the Three Gorges Dam displaced more people than the three largest Chinese dams before it combined. There is serious concern that China's Three Gorges Dam may fail due to heavy flooding. A full 4.27 km3 (1.02 cu mi) of flood water was captured and the river flow was cut by as much as 15,000 m3 (530,000 cu ft) per second.[72]. According to the Ministry of Environmental Protection, as of April 2007, more than 50 new plants could treat 1.84 million tonnes per day, 65% of the total need. According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. The report said the towers had reached 189 m (620 ft) of the anticipated 195 m (640 ft), the towers would be completed by June 2012 and the entire shiplift in 2015. The original plans called for the dam to employ a unique method for moving ships: the ships would enter locks located at the lower and upper ends of the dam and then cranes would move the ships from one lock to the next.
