did the three gorges dam collapse

[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. The Three Gorges Dam was designed to tame China's longest river. The disaster could kill an estimated 171,000 people and 11 million people will lose their homes.. 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 flow rate varies between 600–950 cubic metres per second (21,000–34,000 cu ft/s) depending on the head available. [10] After nine years of construction, installation and testing, the power plant was fully operational by July 2012. [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. [80][81], According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. [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. 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). [20][21] Because of that, the dam has been controversial both domestically and abroad. Additional charges were assessed as follows: Every province receiving power from the Three Gorges Dam had to pay ¥7.00 per MWh extra. Pollution. In 1998, a flood in the same area caused billions of dollars in damage; 2,039 km2 (787 sq mi) of farmland were flooded. Higher-paying customers, such as Shanghai, receive priority. [103] The 1954 flood carried 50 cubic kilometres (12 cu mi) of water. [132] About 140,000 residents were relocated to other provinces. [93] This region has long been known for its rich biodiversity. The dam's reservoir rose nearly 3 m (9.8 ft) in 24 hours and reduced the outflow to 40,000 m3/s (1,400,000 cu ft/s) in discharges downstream, effectively alleviating serious impacts on the middle and lower river. 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. 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%. 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. 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. In fact, Chinese Government scholars even claim that the Three Gorges Dam directly caused the extinction of the baiji. [106] This increases the flow rate of the river downstream, and provides fresh water for agricultural and industrial usage. Three Gorges Dam, dam on the Yangtze River (Chang Jiang) just west of the city of Yichang in China. I’m not going to quantify the damage, it’s very clear that the collapse would be catastrophic. [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. However, electricity demand has increased more quickly than previously projected. Some newer ones are air-cooled, which are simpler in design and manufacture and are easier to maintain. [126], In late 2012, preliminary work started along both future railway routes. 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. [84] One is that sedimentation projections are not agreed upon, and the other is that the dam sits on a seismic fault. [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. [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. In 2012, the dam's 32 generating units generated a record 98.1 TWh of electricity, which accounts for 14% of China's total hydro generation. Th photo, taken on August 17, 2020, shows water gushing out from the Three Gorges Dam in southwest China's Chongqing province. A similar separation is used on the downstream side, seen partially in the preceding image. [37] It has a combined generating capacity of 22.5 gigawatts and a designed annual generation capacity of 88.2 billion kilowatt hours. [13] The sixth (No. Groups of craft would be lifted together for efficiency. This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. re: Is the Three Gorges Dam About to Collapse? [82] ... For those who remembered the collapse … [124]Shanghai Daily reported that the first operational use of the lift was on September 18, 2016, when limited "operational testing" of the lift began. [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.

The turbine diameter is 9.7/10.4 m (VGS design/Alstom's design) and the rotation speed is 75 revolutions per minute. The region also provides habitats to hundreds of freshwater and terrestrial animal species. Three Gorges Dam secretly discharged, internal doc reveals; China firm used fake gold to obtain loan ; Three Gorges Dam releasing floodwater from spillway deliberately? [40], The government estimated that the Three Gorges Dam project would cost 180 billion yuan (US$22.5 billion). When there is enough flow, power output is limited by plant generating capacity. [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. [105] In early August 2009, the largest flood in five years passed through the dam site. [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. [36], In February 2012, Xinhua reported that the four towers that are to support the ship lift had almost been completed.[120]. 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. In November 2007, it was reported in the local media that construction of the ship lift started in October 2007. [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. However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. var js, fjs = d.getElementsByTagName(s)[0]; The ship lift is to the right of the dam body with its own designated waterway. [50][51][52][53], As of May 23, 2012, when the last main generator, No. It is conjectured that this could have extreme cascading effects, involving 16 nuclear power plants downstream. 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. The ship locks are to the right (northeast) of the ship lift. Torrential rains have been causing havoc throughout the southwest and central region this month, with many rivers bursting their banks, prompting mass evacuations. [78], Power is distributed over multiple 500 kV transmission lines. The dam discharges its reservoir during the dry season between December and March every year. The Tibet Autonomous Region pays no surcharge. 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. [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. 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). 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. Immediately after the first filling of the reservoir, around 80 hairline cracks were observed in the dam's structure,[144][145][146] however an experts group gave the project overall a good quality rating[147] and the 163,000 concrete units all passed quality testing, with normal "deformation" within design limits. Experts are concerned the Three Gorges Dam is in danger of collapse due to a combination of the volume of rain failing and satellite photo's comparing the dam between 2009 and 2019 that indicate the dam has warped since it's construction. No. [15][31][35] The ship lift was completed in 2015. The ship lift can lift ships of up to 3,000 tons. Shanghai, more than 1,600 km (990 mi) away, rests on a massive sedimentary plain. [76] Nine provinces and two cities consume power from the dam. 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. The alternating current (AC) lines to the Central China Grid have a total capacity of 12,000 MW. At current levels, 80% of the land in the area is experiencing erosion, depositing about 40 million tons of sediment into the Yangtze annually. [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. In addition, populations of the Yangtze sturgeon are guaranteed to be "negatively affected" by the dam. 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. The trials of elevator finished in July 2016, the first cargo ship was lifted on July 15, the lift time comprised 8 minutes. The dam is expected to minimize the effect of even a "super" flood. JOIN OVER 35,000+ PATRIOTS IN RECEIVING REAL, ACCURATE, AND AMERICAN-CENTRIC NEWS! [68][69] In July 2008 it generated 10.3 TWh of electricity, its first month over 10 TWh. The wall beyond is to separate spillway and turbine flows from the lock and ship lift upstream approach channel. The technology transfer agreement was signed together with the contract. 22 began operation on June 11, 2007, and No. [16], As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity. [39] The concrete dam wall is 181 m (594 ft) high above the rock basis. };

After the 1954 Yangtze River Floods, in 1956, Mao Zedong authored "Swimming", a poem about his fascination with a dam on the Yangtze River. “Since it was built, it has never played a role in preventing flooding or droughts, like we thought it would back then.”. 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. [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. Concerns about the potential wildlife impact of the dam predate the National People's Congress's approval in 1992. Source link. Two short rail lines, one on each side of the river, are to be constructed. Despite protests by residents and environmentalists, the Three Gorges Dam was completed in 2006 after a 12-year build. [98] The dam contributed to the functional extinction of the baiji Yangtze river dolphin. On a more serious … 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. [118][119] Many other fish are injured in the turbine blades of the hydroelectric plants as well. The Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. The designed hydraulic head of the generator is 80.6 meters (264 ft). Millions of people live downstream of the dam, with many large, important cities like Wuhan, Nanjing, and Shanghai located adjacent to the river. 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 largest dam in the world, it allows the navigation of oceangoing freighters, generates hydroelectric power, and may offer flood protection. From 2004 to 2007, a total of 198 million tonnes of freight passed through the locks. Shipping will become safer, since the gorges are notoriously dangerous to navigate. But this summer's record rains reveal its limited ability to control floods. This capacity will reduce the frequency of major downstream flooding from once every 10 years to once every 100 years. 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. Average efficiency is over 94%, and reaches 96.5%. 27, finished its final test, the six underground main generators are also in operation, raising capacity to 22.5 GW. [116] One complicating factor is that the water level can vary dramatically. [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). [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. 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. 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. China finally admits Its Three Gorges Dam has ‘deformed slightly’ but claims it happened over the weekend, ignoring reports this happened long ago. The country already is a net food importer. js.src = "https://connect.facebook.net/en_US/sdk.js"; 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 read geology as an option in university. FB.init({ 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. Stand up to power, stand up to the establishment, and join us in the fight against the mainstream media! It is home to 6,388 species of plants, which belong to 238 families and 1,508 genera. The Three Gorges dam on the Yangtze River in China may be on the verge of collapse. The Three Gorges Dam didn’t have a separate body for quality inspection.

// Load the SDK asynchronously The actual power output in 2008 was obtained based on the monthly electricity sent to the grid. 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]. [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. [29] Some 54 Chinese engineers went to the U.S. for training. The dam was a pet project of the late Premier Li Peng and a monumental pride of the nation when it blocked and diverted Asia’s largest river in 1997. [31], During the 1980s, the idea of a dam reemerged. In 1939, during the Second Sino-Japanese War, Japanese military forces occupied Yichang and surveyed the area. [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). If it's true, it would be a catastrophe beyond comprehension. …Zhang Jianping, an activist in Jiangsu, is skeptical. 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. [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. Accordingly to numerous reports, the world's largest dam is in severe difficulty due to upstream flooding. "[142], The Three Gorges Dam is a steel-concrete gravity dam. [28] In 1932, the Nationalist government, led by Chiang Kai-shek, began preliminary work on plans in the Three Gorges. 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. 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. But the integrity of the Three Gorges Dam remains under fire, as officials say despite draining efforts, constant rain may still see it collapse. Learn more about the Three Gorges Dam. It also improves shipping conditions. Flooding in the area is much worse than ever before and… For example, the hanging coffins site high in the Shen Nong Gorge is part of the cliffs. 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. If the Three Gorges Dam collapses there would be a catastrophic type of failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release. The greater the head, the less water needed to reach full power. As there are separate sets of locks for upstream and downstream traffic, this system is more water efficient than bi-directional staircase locks. The point here is that anyone concerned about food anywhere should want to think through what they might do if the TGD failed. 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. “With hindsight, I think that all those experts who opposed the buildings of the Three Gorges were right,” Zhang said on Radio Free Asia. What happens if it does? [125], Plans also exist for the construction of short portage railways bypassing the dam area altogether. ", "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?? Completely interpretation their picture within the Tv set play, the eternally Piaget duplicate wrist watches with. 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. The gates are the vulnerable hinged type, which, if damaged, could temporarily render the entire flight unusable. First time I've heard of this story. In addition to the canal locks, there is a ship lift, a kind of elevator for vessels. 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. As of May 2014, the ship lift was expected to be completed by July 2015. [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 a result, damage to an individual section should not affect other parts of the dam. 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. The team that designed and constructed the dam did it themselves. Annual electricity generation in 2018 was 101.6 TWh,[7] which is 20 times more than the Hoover Dam. Fast-flowing floodwaters hit the dam… "Slight deformation" on some peripheral parts of the structure was reported by local media last week. Other provinces had to pay an additional charge of ¥4.00 per MWh. The water level upstream drops from 175 to 145 m (574 to 476 ft),[107] preparing for the rainy season. [5][6] The dam generates an average 95±20 TWh of electricity per year, depending on annual amount of precipitation in the river basin. [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. Bearing load is 5050/5500 tonnes. Concerns are rising that China's Three Gorges Dam, the world's largest dam, could be on the verge of collapse triggering a devastating 250-foot tidal wave that would wipe out cities, reported The Sun. Since then, the price has varied by province, from ¥228.7–401.8 per MWh. Last month the mysterious, exiled Chinese billionaire and whistleblower Miles Guo said that the Three Gorges Dam could collapse soon. Model of the Three Gorges Dam showing the ship lift and the ship lock. [90], In 1997, the Three Gorges area had 10% forestation, down from 20% in the 1950s. An important function of the dam is to control flooding, which is a major problem for the seasonal river of the Yangtze. Satellite image via NASA shows water moving through the Three Gorges Dam in mid-June. [32][33] Construction started on December 14, 1994. Each main water turbine has a capacity of 700 MW. 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. Before the dam was constructed, the maximum freight capacity at the Three Gorges site was 18.0 million tonnes per year. [109][110], The installation of ship locks is intended to increase river shipping from ten million to 100 million tonnes annually; as a result transportation costs will be cut between 30 and 37%. This is largely due to China's large reforestation effort. The dam could only divert the water above Chenglingji, leaving 30 to 40 km3 (7.2 to 9.6 cu mi) to be diverted. This has left the water looking stagnant, polluted and murky. 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. [99], In 2005, NASA scientists calculated that the shift of water mass stored by the dams would increase the total length of the Earth's day by 0.06 microseconds and make the Earth slightly more round in the middle and flat on the poles.[100]. One of the things to consider when building a dam is the water impounded behind the dam. 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. A conservative publication and syndicator with one aspiration to fulfill: a media platform where truth conquers all. – – FAILED DAMS UPSTREAM OF THREE GORGES DAM COLLAPSE- Very Good Analysis ; Behind the Three Gorges Dam 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). 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. Copyrights reserved to authors by way of attribution. The moving mass (including counterweights) is 34,000 tonnes. 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. 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. [8][9], The dam body was completed in 2006. 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.
