The technology transfer agreement was signed together with the contract. The Asian Times reported yesterday: 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. Building the Three Gorges Dam displaced more people than the three largest Chinese dams before it combined. In addition, populations of the Yangtze sturgeon are guaranteed to be "negatively affected" by the dam. [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. The country already is a net food importer. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. The Chinese government has moved to defend the structural integrity of the massive Three Gorges Dam, as a hydrology expert took to international media over the weekend to warn it could collapse … 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. No. 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. [48], The first north side main generator (No. The dam has come under new scrutiny after devastating flooding over the past few weeks. In 1958, after the Hundred Flowers Campaign, some engineers who spoke out against the project were imprisoned. There is serious concern that China's Three Gorges Dam may fail due to heavy flooding. [124] [138], The 600 km (370 mi) long reservoir flooded some 1,300 archaeological sites and altered the appearance of the Three Gorges as the water level rose over 91 m (300 ft). [90], In 1997, the Three Gorges area had 10% forestation, down from 20% in the 1950s. Three Gorges Dam Collapse - The Exact Simulation. A 3D simulation test of the Three Gorges Dam breaking and the devastation that follows… July 24, 2020 by IWB Facebook Twitter Reddit Email RSS Feed Newsletter Donate Cheng says that the flood has already raised the water dammed behind the Three Gorges to 50 — fifty — feet higher than the maximum flood level. var js, fjs = d.getElementsByTagName(s)[0]; Even before construction of the Three Gorges Dam began in 1994, many experts were already criticizing the project. China's Three Gorges Dam faces mounting pressure from raging floodwaters amid fears the huge hydropower plant could COLLAPSE. window.fbAsyncInit = function() { [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. [94] Freshwater fish are especially affected by dams due to changes in the water temperature and flow regime. [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. “With hindsight, I think that all those experts who opposed the buildings of the Three Gorges were right,” Zhang said on Radio Free Asia. Don't miss out! 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. 22 began operation on June 11, 2007, and No. Please update this article to reflect recent events or newly available information. Three Gorges uses Francis turbines. 9. [127], Though the large size of the reservoir caused huge relocation upstream, it was considered justified by the flood protection it provides for communities downstream. September 7, 2020 by IWB. The wall beyond is to separate spillway and turbine flows from the lock and ship lift upstream approach channel. The official Xinhua News Agency quoted the operator of the the world’s largest hydroelectric gravity dam as saying that some nonstructural, peripheral parts of the dam had buckled. 27, finished its final test, the six underground main generators are also in operation, raising capacity to 22.5 GW. [34] The dam was expected to be fully operational in 2009, but additional projects, such as the underground power plant with six additional generators, delayed full operation until May 2012. Experts recommend that, in the case of the Three Gorges Dam, at least 600 million people living downstream of the Yangtze River, including residents of Shanghai and Wuhan, will be submerged in water and severely affected. 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. [32][33] Construction started on December 14, 1994. From 2003 to 2007, power production equaled that of 84 million tonnes of standard coal.[83]. Though it was close to this level even at the start of construction, the dam further decreased its habitat and increased ship travel, which are among the factors causing what will be its ultimate demise. However, the municipal government explained that the relocation is due to urbanization, rather than the dam, and people involved included other areas of the municipality. [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. The ship lift takes 30 to 40 minutes to transit, as opposed to the three to four hours for stepping through the locks. [83], There are two series of ship locks installed near the dam (30°50′12″N 111°1′10″E / 30.83667°N 111.01944°E / 30.83667; 111.01944). However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. [70] On June 30, 2009, after the river flow rate increased to over 24,000 m3/s, all 28 generators were switched on, producing only 16,100 MW because the head available during flood season is insufficient. 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. Full cost recovery was thus expected to occur ten years after the dam started full operation,[41] but the full cost of the Three Gorges Dam was recovered by December 20, 2013. The provinces of Hunan, Henan and Hubei, where the Three Gorges dam is located, were also braced for heavy rain on Thursday. Due to extensive monsoon of 2020 year with heavy rainfalls, the annual production reached ~112 TWh that year, which broke the previous world record of annual production by Itaipu Dam equal to ~103 TWh of 2016 year. [118][119] 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. Besides, Mr. Wang pointed out that the design, construction and quality assessment of the dam were all done by the same expert teams and the project completion time was too fast. The freight capacity of the river increased six times and the cost of shipping was reduced by 25%. [72], During the November to May dry season, power output is limited by the river's flow rate, as seen in the diagrams on the right. The point here is that anyone concerned about food anywhere should want to think through what they might do if the TGD failed. Source link. Bearing load is 5050/5500 tonnes. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. Shopping. 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. Copyrights reserved to authors by way of attribution. The absence of silt downstream has three effects: Erosion in the reservoir, induced by rising water, causes frequent major landslides that have led to noticeable disturbance in the reservoir surface, including two incidents in May 2009 when somewhere between 20,000 and 50,000 cubic metres (26,000 and 65,000 cu yd) of material plunged into the flooded Wuxia Gorge of the Wu River. The flood affected more than 2.3 million people, killing 1,526. 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. Facebook Twitter Reddit Email RSS Feed Newsletter Donate. Shanghai, more than 1,600 km (990 mi) away, rests on a massive sedimentary plain. [95] Already, the percentage of forested area in the region surrounding the Three Gorges Dam has dropped from twenty percent in 1950 to less than ten percent as of 2002,[95] negatively affecting all plant species in this locality. 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...", This page was last edited on 15 January 2021, at 04:41. And that if it fails, it would kill millions of people, perhaps 100 million according to some claims, and displace even more. Additional charges were assessed as follows: Every province receiving power from the Three Gorges Dam had to pay ¥7.00 per MWh extra. The water level upstream drops from 175 to 145 m (574 to 476 ft),[107] preparing for the rainy season. The region also provides habitats to hundreds of freshwater and terrestrial animal species. The water also powers the Gezhouba Dam downstream. Concerns about the potential wildlife impact of the dam predate the National People's Congress's approval in 1992. [28] In 1932, the Nationalist government, led by Chiang Kai-shek, began preliminary work on plans in the Three Gorges. The water is held back by the innate mass of the individual dam sections. But not just to China. [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. Three Gorges Dam Collapse - The Exact Simulation - YouTube. 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. [139] Cultural and historical relics are being moved to higher ground as they are discovered, but the flooding inevitably covered undiscovered relics. [96] Other aquatic species have been endangered by the dam, particularly the baiji, or Chinese river dolphin,[85] now extinct. Another eight dams are in the midstream of the Jinsha and eight more upstream of it. 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. China's Three Gorges Dam in danger of collapse any time. Concerns over the integrity of the Three Gorges Dam are mounting after a video went viral simulating the destruction that could happen if the dam were to collapse. view more headlines . 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. …Zhang Jianping, an activist in Jiangsu, is skeptical. [98] The dam contributed to the functional extinction of the baiji Yangtze river dolphin. The trials of elevator finished in July 2016, the first cargo ship was lifted on July 15, the lift time comprised 8 minutes. [29] Some 54 Chinese engineers went to the U.S. for training. Then in 2018 it was reported online that pictures show that the Three Gorges Dam has moved: An expert on the region’s … [116] One complicating factor is that the water level can vary dramatically. 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. The generator produces electrical power at 20 kV. [8][9], The dam body was completed in 2006. [31], During the 1980s, the idea of a dam reemerged. [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. Last week we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. Three direct current (DC) lines to the East China Grid carry 7,200 MW: Three Gorges – Shanghai (3,000 MW), HVDC Three Gorges – Changzhou (3,000 MW), and HVDC Gezhouba – Shanghai (1,200 MW). When the water level is at its maximum of 175 m (574 ft) above sea level, 110 m (361 ft) higher than the river level downstream, the dam reservoir is on average about 660 km (410 mi) in length and 1.12 km (3,675 ft) in width. [121] It was tested in December 2015 and announced complete in January 2016. The DC transmission line HVDC Three Gorges – Guangdong to the South China Grid has a capacity of 3,000 MW. In 1944, the United States Bureau of Reclamation's head design engineer, John L. Savage, surveyed the area and drew up a dam proposal for the 'Yangtze River Project'. In fact, Chinese Government scholars even claim that the Three Gorges Dam directly caused the extinction of the baiji. Shopping. Info. According to a forecast, the inbound flow of water is expected to reach more than 74,000 cubic meters per second after continuous heavy rain battered the upper reaches of … About 32 landfills were added, which could handle 7,664.5 tonnes of solid waste every day. [13] The sixth (No. All other rights are reserved for The Spectator Media, unless otherwise noted. [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. “Since it was built, it has never played a role in preventing flooding or droughts, like we thought it would back then.”. [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 collapse of the TGD would perhaps be the single largest disaster that could affect the world’s food security because aside from the immediate disaster there would be enormous upward pressure on food prices, putting essential staples out of reach of hundreds of millions of people outside China. Annual electricity generation in 2018 was 101.6 TWh,[7] which is 20 times more than the Hoover Dam. The Tibet Autonomous Region pays no surcharge. The total capacity of those four dams is 38,500 MW,[148] almost double the capacity of the Three Gorges. Each main water turbine has a capacity of 700 MW. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. Plenty of farm land and China's most important industrial area are built beside the river. Stand up to power, stand up to the establishment, and join us in the fight against the mainstream media! A design, the Otani plan, was completed for the dam in anticipation of a Japanese victory over China. [93] This region has long been known for its rich biodiversity. 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. It’s well worth watching because when the dam goes, besides the tragic consequences for the Chinese people it will have serious economic and political effects throughout the world. This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. [97] The Chinese paddlefish is also believed extinct in part due to the dam blocking its migration. [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. Groups of craft would be lifted together for efficiency. 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. The gates are the vulnerable hinged type, which, if damaged, could temporarily render the entire flight unusable. As many as 400 million lives may be at risk as torrential rain in China threatens the world’s largest dam. [76] Nine provinces and two cities consume power from the dam. Millions of people live downstream of the dam, with many large, important cities like Wuhan, Nanjing, and Shanghai located adjacent to the river. xfbml : true, // parse social plugins on this page [111] The locks are 280 m long, 35 m wide, and 5 m deep (918 × 114 × 16.4 ft). [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. and bang up to date video. The reservoir's flood storage capacity is 22 cubic kilometres (5.3 cu mi; 18,000,000 acre⋅ft). // initializing facebook On completion, the reservoir flooded a total area of 632 km2 (244 sq mi) of land, compared to the 1,350 km2 (520 sq mi) of reservoir created by the Itaipu Dam. [91] Over one billion tons of wastewater are released annually into the river,[85] which was more likely to be swept away before the reservoir was created. The Three Gorges Dam built on the river Yangtze River has been deemed a a environmentally hazardous project right from its beginning given its geographical position and its effect on earth plates. In 1939, during the Second Sino-Japanese War, Japanese military forces occupied Yichang and surveyed the area. Th photo, taken on August 17, 2020, shows water gushing out from the Three Gorges Dam in southwest China's Chongqing province. 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. [77], Power distribution and transmission infrastructure cost about 34.387 billion yuan. Info. [134][135][136] 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: I’m not going to quantify the damage, it’s very clear that the collapse would be catastrophic. In addition to the canal locks, there is a ship lift, a kind of elevator for vessels. For example, the hanging coffins site high in the Shen Nong Gorge is part of the cliffs. If playback doesn't begin shortly, try restarting your device. It is home to 6,388 species of plants, which belong to 238 families and 1,508 genera. By the time night fell on Aug. 8, as many as 65 area dams had collapsed. The project used 27.2 million m3 (35.6 million cu yd) of concrete (mainly for the dam wall), used 463,000 tonnes of steel (enough to build 63 Eiffel Towers), and moved about 102.6 million m3 (134.2 million cu yd) of earth. [12] Among those 32 main generators, 14 are installed in the north side of the dam, 12 in the south side, and the remaining six in the underground power plant in the mountain south of the dam. Scientist Wang Weiluo said that the Three Gorges Dam was not as stable as many people thought. Watch later. After the 1954 Yangtze River Floods, in 1956, Mao Zedong authored "Swimming", a poem about his fascination with a dam on the Yangtze River. ", "NASA Details Earthquake Effects on the Earth", "39.1931, 1935, 1954, 1998 年长江流域发生的4次大洪水造成了怎样的洪水灾害?? By providing flood storage space, the dam reduces the potential for floods downstream which could possibly affect millions. In 1998, a flood in the same area caused billions of dollars in damage; 2,039 km2 (787 sq mi) of farmland were flooded. version : "" [37] It has a combined generating capacity of 22.5 gigawatts and a designed annual generation capacity of 88.2 billion kilowatt hours.
