did the three gorges dam collapse

Each main water turbine has a capacity of 700 MW. [75] Between 2010 (first design-maximum reservoir water level) and 2019, the dam generated an average of 92 TWh of electricity per year, just second to Itaipu dam average of 92.8 TWh of electricity per year during the same period. [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. [citation needed]. [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. cookie : true, // enable cookies to allow the server to access 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. [80][81], According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. This has left the water looking stagnant, polluted and murky. 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. It is not known whether this solution was considered for its water-saving performance or because the engineers thought the difference in height between the river above and below the dam too great for alternative methods. 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 the Yangtze River. [105] In early August 2009, the largest flood in five years passed through the dam site. ", In order to maximize the utility of the Three Gorges Dam and cut down on sedimentation from the Jinsha River, the upper course of the Yangtze River, authorities plan to build a series of dams on the Jinsha, including Wudongde Dam, Baihetan Dam, along with the now completed Xiluodu and Xiangjiaba dams. The Three Gorges dam on the Yangtze River in China may be on the verge of collapse. The ship lift's design uses a helical gear system, to climb or descend a toothed rack. The turbine diameter is 9.7/10.4 m (VGS design/Alstom's design) and the rotation speed is 75 revolutions per minute. First time I've heard of this story. [77], Power distribution and transmission infrastructure cost about 34.387 billion yuan. From 2004 to 2007, a total of 198 million tonnes of freight passed through the locks. [82] Three Gorges Dam, dam on the Yangtze River (Chang Jiang) just west of the city of Yichang in China. [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. However, electricity demand has increased more quickly than previously projected. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. [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. 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). As of May 2014, the ship lift was expected to be completed by July 2015. [79], The dam was expected to provide 10% of China's power. [96] Other aquatic species have been endangered by the dam, particularly the baiji, or Chinese river dolphin,[85] now extinct. if (d.getElementById(id)) return; 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. A design, the Otani plan, was completed for the dam in anticipation of a Japanese victory over China. 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. 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. Torrential rains have been causing havoc throughout the southwest and central region this month, with many rivers bursting their banks, prompting mass evacuations.

For example, the hanging coffins site high in the Shen Nong Gorge is part of the cliffs. 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. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. Huang predicted numerous negative consequences should the Three Gorges Dam be built, including the collapse of downstream banks, silting problems, frequent earthquakes, the spread of a disease called schistosomiasis, which is caused by parasitic flatworms, decrease in water quality, upstream flooding, and voyage issues. Then in 2018 it was reported online that pictures show that the Three Gorges Dam has moved: An expert on the region’s food supply, Geoff Quartermaine Bastin, provided this analysis regarding the impact on the world’s food supply should the massive dam break: The collapse of the TGD would destroy all the cropland and livestock downstream, destroy major cities such as Wuhan and could threaten Shanghai. [16], As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity. The dam is expected to minimize the effect of even a "super" flood. [40], The government estimated that the Three Gorges Dam project would cost 180 billion yuan (US$22.5 billion). However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. The ship lift must work even if water levels vary by 12 meters (39 ft) on the lower side, and 30 m (98 ft) on the upper side. 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'. On July 18, 2020, the Chinese state-run press agency Xinhua News Agency stated that "the monitoring records of the Three Gorges Project's operation department showed that the average values of the main parameters such as dam displacement, seepage, and deformation were within the normal range, and the safety indicators of the dam's water retaining structure were stable. Three Gorges Dam secretly discharged, internal doc reveals; China firm used fake gold to obtain loan ; Three Gorges Dam releasing floodwater from spillway deliberately? Completely interpretation their picture within the Tv set play, the eternally Piaget duplicate wrist watches with. 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. Millions were displaced as an area of about 600 kilometers was submerged to create the world’s largest dam and hydroelectricity facilities. Shipping will become safer, since the gorges are notoriously dangerous to navigate. Please update this article to reflect recent events or newly available information. [16][36] The dam had raised the water level in the reservoir to 172.5 m (566 ft) above sea level by the end of 2008 and the designed maximum level of 175 m (574 ft) by October 2010.[37][38]. Satellite image via NASA shows water moving through the Three Gorges Dam in mid-June. };

[20][21] Because of that, the dam has been controversial both domestically and abroad. 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. This is largely due to China's large reforestation effort. }(document, "script", "facebook-jssdk")); The water level upstream drops from 175 to 145 m (574 to 476 ft),[107] preparing for the rainy season. Stand up to power, stand up to the establishment, and join us in the fight against the mainstream media! [78], Power is distributed over multiple 500 kV transmission lines. 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. About 32 landfills were added, which could handle 7,664.5 tonnes of solid waste every day. 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. It is home to 6,388 species of plants, which belong to 238 families and 1,508 genera. [48], The first north side main generator (No. Three Gorges uses Francis turbines. Some newer ones are air-cooled, which are simpler in design and manufacture and are easier to maintain. [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. 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. The maximum power-output curves were calculated based on the average flow rate at the dam site, assuming the water level is 175 m and the plant gross efficiency is 90.15%. Higher-paying customers, such as Shanghai, receive priority. As a result, damage to an individual section should not affect other parts of the dam. [104] Also, the dam cannot protect against some of the large tributaries downstream, including the Xiang, Zishui, Yuanshui, Lishui, Hanshui, and the Gan. ", "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?? Accordingly to numerous reports, the world's largest dam is in severe difficulty due to upstream flooding. It would affect the Grand Canal systems and so spill over into the Yellow River Region. fjs.parentNode.insertBefore(js, fjs); [12][14][15] The last major component of the project, the ship lift, was completed in December 2015. Two hazards are uniquely identified with the dam. Shanghai, more than 1,600 km (990 mi) away, rests on a massive sedimentary plain. Weeks of heavy rain have put the Three Gorges Dam, the largest hydropower project in the world, in danger of collapse putting 400 million people at risk. [76] Nine provinces and two cities consume power from the dam. The gates are the vulnerable hinged type, which, if damaged, could temporarily render the entire flight unusable. Source link. xfbml : true, // parse social plugins on this page Bearing load is 5050/5500 tonnes. [50][51][52][53], As of May 23, 2012, when the last main generator, No. The Three Gorges Dam was designed to tame China's longest river. The outer diameter of the generator stator is 21.4/20.9 m. The inner diameter is 18.5/18.8 m. The stator, the biggest of its kind, is 3.1/3 m in height. The Three Gorges Dam is the world's largest capacity hydroelectric power station with 34 generators: 32 main generators, each with a capacity of 700 MW, and two plant power generators, each with capacity of 50 MW, making a total capacity of 22,500 MW. 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. [117], The ship lift was not yet complete when the rest of the project was officially opened on May 20, 2006. Three Gorges Dam collapse. This capacity will reduce the frequency of major downstream flooding from once every 10 years to once every 100 years. The disaster could kill an estimated 171,000 people and 11 million people will lose their homes.. The trials of elevator finished in July 2016, the first cargo ship was lifted on July 15, the lift time comprised 8 minutes. The smaller dam’s failure had not been reported by local media, raising questions of what the Chinese government could be hiding about the Three Gorges. Maximum vessel size is 10,000 tons. The National People's Congress approved the dam in 1992: out of 2,633 delegates, 1,767 voted in favour, 177 voted against, 664 abstained, and 25 members did not vote, giving the legislation an unusually low 67.75% approval rate. 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. The designed hydraulic head of the generator is 80.6 meters (264 ft). [132] About 140,000 residents were relocated to other provinces. When the dam first began operations, China’s state media made grand claims that the dam can withhold the worst flood in 10,000 years. Other provinces had to pay an additional charge of ¥4.00 per MWh. 6 min read E very Summer there’s news that the Three Gorges dam in China is in imminent danger of collapse. 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. [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). [22][23][24][25], A large dam across the Yangtze River was originally envisioned by Sun Yat-sen in The International Development of China, in 1919. – – FAILED DAMS UPSTREAM OF THREE GORGES DAM COLLAPSE- Very Good Analysis ; Behind the Three Gorges Dam Located in Sandouping (三斗坪), Yichang City, Hubei Province, 38km from Gezhouba Water Control Project at the downstream, Three Gorges Dam is the main work of Three Gorges Project, which is the largest hydropower project in the world. 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. China's controversial Three Gorges Dam, the world's biggest hydropower project, is structurally sound, officials said, denying rumours on social media it was at risk of collapse. In November 2007, it was reported in the local media that construction of the ship lift started in October 2007. Model of the Three Gorges Dam showing the ship lift and the ship lock. “Since it was built, it has never played a role in preventing flooding or droughts, like we thought it would back then.”. China's Three Gorges Dam faces mounting pressure from raging floodwaters amid fears the huge hydropower plant could COLLAPSE. An important function of the dam is to control flooding, which is a major problem for the seasonal river of the Yangtze. [117] An article in Steel Construction says the actual time of the lift will be 21 minutes. The Tibet Autonomous Region pays no surcharge. 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. 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. It is conjectured that this could have extreme cascading effects, involving 16 nuclear power plants downstream. When there is enough flow, power output is limited by plant generating capacity. The flow rate varies between 600–950 cubic metres per second (21,000–34,000 cu ft/s) depending on the head available. [31], During the 1980s, the idea of a dam reemerged. [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. [101][102] In 1954, the river flooded 193,000 km2 (74,500 sq mi), killing 33,169 people and forcing 18,884,000 people to move. “With hindsight, I think that all those experts who opposed the buildings of the Three Gorges were right,” Zhang said on Radio Free Asia. [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. By providing flood storage space, the dam reduces the potential for floods downstream which could possibly affect millions. [112][113] That is 30 m (98 ft) longer than those on the St Lawrence Seaway, but half as deep. Flooding in the area is much worse than ever before and… Each of them is made up of five stages, with transit time at around four hours. Despite protests by residents and environmentalists, the Three Gorges Dam was completed in 2006 after a 12-year build. Since the filling of the reservoir in 2003, the Three Gorges Dam has supplied an extra 11 km3 (2.6 cu mi) of fresh water to downstream cities and farms during the dry season. The point here is that anyone concerned about food anywhere should want to think through what they might do if the TGD failed. In 2018, the dam generated 101.6 terawatt-hours (TWh), breaking its previous record, but was still slightly lower than the Itaipú Dam, which had set the world record in 2016 after producing 103.1 TWh. }); [36], In February 2012, Xinhua reported that the four towers that are to support the ship lift had almost been completed.[120]. [8][9], The dam body was completed in 2006. The ship locks are to the right (northeast) of the ship lift. [149] Baihetan is under construction and Wudongde is seeking government approval. 9. [103] The 1954 flood carried 50 cubic kilometres (12 cu mi) of water.

// Load the SDK asynchronously // the session [137], Allegedly, funds for relocating 13,000 farmers around Gaoyang disappeared after being sent to the local government, leaving residents without compensation. 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. [68][69] In July 2008 it generated 10.3 TWh of electricity, its first month over 10 TWh. No. One of the things to consider when building a dam is the water impounded behind the 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. Shortly before 1:30 this morning, the 13th federal inmate in the past, President Trump confidante Mike Lindell appears to be the only one left, Antifa supporter Daniel Alan Baker was arrested for plotting to murder Trump, Back in 1775 there used to be a place for daily political, Joe Biden’s inauguration rehearsal has been postponed due to security concerns. After the 1949 Communist Revolution, Mao Zedong supported the project, but began the Gezhouba Dam project nearby first, and economic problems including the Great Leap Forward and the Cultural Revolution slowed progress. Plenty of farm land and China's most important industrial area are built beside the river. // initializing facebook Most of the generators are water-cooled. [41] By the end of 2008, spending had reached 148.365 billion yuan, among which 64.613 billion yuan was spent on construction, 68.557 billion yuan on relocating affected residents, and 15.195 billion yuan on financing. "[141], The notion that the military in Taiwan would seek to destroy the dam provoked an angry response from the mainland Chinese media. [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. [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). Beijing has admitted in a rare revelation that ts 2.4-kilometer Three Gorges Dam spanning the Yangtze River in Hubei province “deformed slightly”, with some nonstructural, peripheral parts of the dam had buckled, after record flooding. I read geology as an option in university. [125], Plans also exist for the construction of short portage railways bypassing the dam area altogether. JOIN OVER 35,000+ PATRIOTS IN RECEIVING REAL, ACCURATE, AND AMERICAN-CENTRIC NEWS! The ship lift is to the right of the dam body with its own designated waterway. js = d.createElement(s); js.id = id; [37] It has a combined generating capacity of 22.5 gigawatts and a designed annual generation capacity of 88.2 billion kilowatt hours. This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. [13] The sixth (No. In 1958, after the Hundred Flowers Campaign, some engineers who spoke out against the project were imprisoned. [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. As there are separate sets of locks for upstream and downstream traffic, this system is more water efficient than bi-directional staircase locks. In 1998, a flood in the same area caused billions of dollars in damage; 2,039 km2 (787 sq mi) of farmland were flooded. The largest dam in the world, it allows the navigation of oceangoing freighters, generates hydroelectric power, and may offer flood protection. 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 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. [106] This increases the flow rate of the river downstream, and provides fresh water for agricultural and industrial usage. The dam could only divert the water above Chenglingji, leaving 30 to 40 km3 (7.2 to 9.6 cu mi) to be diverted. The DC transmission line HVDC Three Gorges – Guangdong to the South China Grid has a capacity of 3,000 MW. [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 is 2,308m in length and 185m in height, and the project started from December 14th, 1994, and it's completed and fully functional as of July 4th, 2012 (except for a ship lift, which was completed in December 2015). "[142], The Three Gorges Dam is a steel-concrete gravity dam. But the integrity of the Three Gorges Dam remains under fire, as officials say despite draining efforts, constant rain may still see it collapse. [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.

The total capacity of those four dams is 38,500 MW,[148] almost double the capacity of the Three Gorges. The flood affected more than 2.3 million people, killing 1,526. The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. [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. Millions of people live downstream of the dam, with many large, important cities like Wuhan, Nanjing, and Shanghai located adjacent to the river.
