The dam is expected to minimize the effect of even a "super" flood. 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 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. 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. ... For those who remembered the collapse … 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. 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. 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. That is a significant change from the 13,000 km2 (5,000 sq mi) net loss of forest each year in the 1990s. 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 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. In 1958, after the Hundred Flowers Campaign, some engineers who spoke out against the project were imprisoned. // initializing facebook The largest dam in the world, it allows the navigation of oceangoing freighters, generates hydroelectric power, and may offer flood protection. Higher-paying customers, such as Shanghai, receive priority. China's Three Gorges Dam faces mounting pressure from raging floodwaters amid fears the huge hydropower plant could 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. 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. [78], Power is distributed over multiple 500 kV transmission lines. 2) started on July 10, 2003; the north side became completely operational September 7, 2005, with the implementation of generator No. 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 Three Gorges Dam has been the world's largest power station in terms of installed capacity (22,500 MW) since 2012. cookie : true, // enable cookies to allow the server to access [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. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9. Groups of craft would be lifted together for efficiency. These locks are staircase locks, whereby inner lock gate pairs serve as both the upper gate and lower gate. The turbine diameter is 9.7/10.4 m (VGS design/Alstom's design) and the rotation speed is 75 revolutions per minute. [117] An article in Steel Construction says the actual time of the lift will be 21 minutes. Accordingly to numerous reports, the world's largest dam is in severe difficulty due to upstream flooding. Concerns about the potential wildlife impact of the dam predate the National People's Congress's approval in 1992. I read geology as an option in university. Th photo, taken on August 17, 2020, shows water gushing out from the Three Gorges Dam in southwest China's Chongqing province. Maximum vessel size is 10,000 tons. 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. The ship lift can lift ships of up to 3,000 tons. However, two weeks ago we reported China’s massive Three Gorges Dam is at risk of blowing, putting 400 million people at risk. Each main water turbine has a capacity of 700 MW. [15][54][55], By August 16, 2011, the plant had generated 500 TWh of electricity. [80][81], According to the National Development and Reform Commission, 366 grams of coal would produce 1 kWh of electricity during 2006. 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 session [32][33] Construction started on December 14, 1994. The Three Gorges Dam didn’t have a separate body for quality inspection. 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. Most of the generators are water-cooled. [48], The first north side main generator (No. "Slight deformation" on some peripheral parts of the structure was reported by local media last week. The ship lift's design uses a helical gear system, to climb or descend a toothed rack. The technology transfer agreement was signed together with the contract. A conservative publication and syndicator with one aspiration to fulfill: a media platform where truth conquers all. The trials of elevator finished in July 2016, the first cargo ship was lifted on July 15, the lift time comprised 8 minutes. [20][21] Because of that, the dam has been controversial both domestically and abroad. 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. "[141], The notion that the military in Taiwan would seek to destroy the dam provoked an angry response from the mainland Chinese media. The 2020 monsoon season has also made people think that the Three Gorges Dam is being put to extreme tests. [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.

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. Two short rail lines, one on each side of the river, are to be constructed. Other provinces had to pay an additional charge of ¥4.00 per MWh. Three Gorges Dam, dam on the Yangtze River (Chang Jiang) just west of the city of Yichang in China. 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). [77], Power distribution and transmission infrastructure cost about 34.387 billion yuan. FB.init({ This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. 9. [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 team that designed and constructed the dam did it themselves. [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. Torrential rains have been causing havoc throughout the southwest and central region this month, with many rivers bursting their banks, prompting mass evacuations. The moving mass (including counterweights) is 34,000 tonnes. It is conjectured that this could have extreme cascading effects, involving 16 nuclear power plants downstream. An important function of the dam is to control flooding, which is a major problem for the seasonal river of the Yangtze. [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. 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. [105] In early August 2009, the largest flood in five years passed through the dam site. [30] 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. The Tibet Autonomous Region pays no surcharge. 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 ship lift is to the right of the dam body with its own designated waterway. [15][31][35] The ship lift was completed in 2015. [121] It was tested in December 2015 and announced complete in January 2016. [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 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 wall beyond is to separate spillway and turbine flows from the lock and ship lift upstream approach channel. [82] Nuclear Power Plants in Danger? The region also provides habitats to hundreds of freshwater and terrestrial animal species. Plenty of farm land and China's most important industrial area are built beside the river. But the integrity of the Three Gorges Dam remains under fire, as officials say despite draining efforts, constant rain may still see it collapse. [16], As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity. However, electricity demand has increased more quickly than previously projected. This capacity will reduce the frequency of major downstream flooding from once every 10 years to once every 100 years. TRENDING: Photo Appears to Show Black Lives Matter Supporters Holding Down and Kneeling on Neck of White Baby. appId : "", New VIDEO: China’s Three Gorges Dam, largest in world, in danger of collapse June 29, 2020 PortandTerminal.com, June 29, 2020 BEIJING – 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. Please update this article to reflect recent events or newly available information. It would affect the Grand Canal systems and so spill over into the Yellow River Region. [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]. [112][113] That is 30 m (98 ft) longer than those on the St Lawrence Seaway, but half as deep. [50][51][52][53], As of May 23, 2012, when the last main generator, No. [132] About 140,000 residents were relocated to other provinces. 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. On a more serious … Millions were displaced as an area of about 600 kilometers was submerged to create the world’s largest dam and hydroelectricity facilities. re: Is the Three Gorges Dam About to Collapse? [103] The 1954 flood carried 50 cubic kilometres (12 cu mi) of water. [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. js = d.createElement(s); js.id = id; 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. Despite protests by residents and environmentalists, the Three Gorges Dam was completed in 2006 after a 12-year build. [94] Freshwater fish are especially affected by dams due to changes in the water temperature and flow regime. Shanghai, more than 1,600 km (990 mi) away, rests on a massive sedimentary plain. 15 started up on October 30, 2008. The ship locks are to the right (northeast) of the ship lift. Even fully operational, on average, it supports only about 1.7% of electricity demand in China in the year of 2011, when the Chinese electricity demand reached 4,692.8 TWh. 22 began operation on June 11, 2007, and No. 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. A similar separation is used on the downstream side, seen partially in the preceding image. Model of the Three Gorges Dam showing the ship lift and the ship lock. 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 alternating current (AC) lines to the Central China Grid have a total capacity of 12,000 MW. [71] During an August 2009 flood, the plant first reached its maximum output for a short period. The total capacity of the ship locks is expected to reach 100 million tonnes per year.[83]. The flood affected more than 2.3 million people, killing 1,526. [28] In 1932, the Nationalist government, led by Chiang Kai-shek, began preliminary work on plans in the Three Gorges. ", 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. In fact, Chinese Government scholars even claim that the Three Gorges Dam directly caused the extinction of the baiji. [68][69] In July 2008 it generated 10.3 TWh of electricity, its first month over 10 TWh. Shipping will become safer, since the gorges are notoriously dangerous to navigate. Pollution. [106] This increases the flow rate of the river downstream, and provides fresh water for agricultural and industrial usage.
