The Three Gorges Dam Case Study
Three Gorges Dam case study

The Three Gorges Dam is a hydroelectric dam on the Yangtze River, and is the worlds largest power station. As well as providing electricity, the dam is also being used to help increase the shipping capacity of the river, as well as reduce the risk of potential floods downstream by acting as a flood storage space. This major alteration is proving to have both positive and negative repercussions.
How has building the dam effected local environment? Despite the Chinese government being adamant that the dam’s positive attributes to the environment, local farmers, citizens and various groups of campaigners have voiced their concern on damaging impacts caused by the dam, including landslides which have consequently caused waves of 50 metres high in the reservoir directly behind the dam. It’s only been since September, at a government - organized conference that the severity of the impacts was touched upon without being dismissed as ‘abnormalities’. Many of the officials running the project brought up that erosion, landslides, environmental degradation and natural disasters have all become more frequent since the dam was constructed, with Wang Xiaofeng (deputy director of the Three Gorges Construction Committee) expressing that ‘We cannot profit from a fleeting economic boom at the cost of sacrificing the environment.” Tan Qiwei, vice-mayor of Chongqing next to the reservoir also state that the bank of the lake had collapsed in 91 places, and that the cause was the huge weight of water behind the dam as well as the differing water level. Local farmers have made similar statements, claiming ‘frightening tremors’ have left cracks in the walls of their home, and a landslide in Hubei Province alongside the reservoir killed over 30 people after burying a bus; heavily conflicting Mr Wang’s statement that ‘There will not be any major damage to life or property’. Water polluting is also a huge problem concerning this dam, with it being blocked

    Warragamba Dam is a concrete dam located in Warragamba, Sydney. It was constructed between 1948 and 1960. It supplies water to 3.4 million people in Greater Sydney. It holds back the water from the Coxs, Kowmung, Natai, Wingecarribee, Wollondilly and Warragamba Rivers, and is fed by a catchment area of 9051 km2. Recent enhancements to the dam were completed in 2009, which included the addition of an auxiliary spillway. The entire dam is 142 metres high, 351 metres in length, and is four times larger than Sydney Harbour, with 2027000 megalitres worth of operating capacity. 3 million tonnes of concrete were used to construct it. The location of this dam was chosen for its large catchment area, and because of the nearby river which was flowing…

    When the Elwha Dam was demolished it was the largest controlled sediment release in a dam removal project anywhere in the world. Because of the amount of sediment behind large dams like the Elwha, the demolition must be done gradually over time to ensure that there is not an overflow of sediment rushed down the river which could cause significant damage to the landscape and the organisms which inhabit it. At the time of the dam removal the Elwha was holding behind it 15,000,000 cubic yards of silt. Sediment buildup isn't the only thing that dams can change about the soil. Many geological occurrences have been blamed on dams.…

    The fish that live in the Elwha River are not able to swim upstream and get the food they need and they cannot reproduce so the salmon population just dominates. The Grand Coulee dam was another but its problem was not fish it was flooding and erosion. I would say this is a very controversial topic because the people might believe pro-environment or some might be pro-economy. My point of view on this topic is I do not understand why we say we want to save the environment but we pay millions of dollars to build dam but in which harm the environment by killing of fish. However, I do understand that dam do provide energy. I believe that if we want to have dam for energy we do not need multiple small dams throughout the country instead build a couple of huge one so you are not killing all the fish you are only killing some of them but you are also getting the energy you…

    In the aftermath of Mao Zedong, China was viewed as a powerless and developing nation. In 2009, the Chinese executed the record-breaking world’s largest engineering and hydropower project on the Yangtze River.1 This 23 billion (US) dollar project is known as the Three Gorges Dam.2 The dam stands at 607 feet tall, stretches over a mile wide, and is equipped with twenty-six generators.3 Not only does this project symbolize China’s power, it provides China with ten percent of its electrical needs using eco-friendly energy.4 5 The massive dam was created on the longest river in China to generate power and control the flooding of the Yangtze River.6 Although the engineers intended for the project to be “green” or not harmful to the environment, biologists, geologists, and environmentalists have all been averse to the dam.7 The Three Gorges Dam is disturbing the ecosystem, biosphere and other natural elements in China. The Three Gorges Dam has been the cause of Earthquakes in China and Reservoir Induced Seismicity. The titanic dam is also responsible for damaging floods and severe tainting of the once clean waters of the Yangtze River.…

    The worst natural disaster in history, the central china floods occurred, from July to August in 1931, when the Yangtze River overflowed and caused a series of floods. As a result of the massive flooding, an estimated 3.7 million people died from drowning, disease and starvation. Over one-fourth of China’s population were affected by the floods. Wives and daughters were sold by desperate people, and in some cases that were reported, there was cases of infanticide ( the intentional killing of infant girls) and also cannibalism. The high water was reached on the 19th of August. The water level was over 53 ft. 200,000 people had drowned in their sleep. Since there wasn’t any money to spare because of the war, they were only able to put up small dams to keep the water at bay on the Yangtze River. When the civil war was over, the Chinese communist party started the Gorges Dam Flood Control project. Which did not successfully take off until the 1980’s and went full operation in 2012. Becoming the world’s largest power…

    Francis Dam was located in San Fracisquito Canyon around present day Santa Clarita. The dam was built without any indication of being an issue until they increased the total height of the dam. The Los Angeles Water Company was the main group in charge of the dam and all associations that went with the dam. The Los Angeles Water Company decided to increase the height of the dam to increase the amount of water that could be stored, in doing so they added a separate wing wall that went left of the main dam. A couple of years later the Los Angeles Water Company decided to increase the overall height of the dam yet again. When they did increase the height of the dam they did not increase the thickness of the damn at the base. This is where the integrity issue arises, the Los Angeles Water Company and their engineers did not increase the thickness of the wall even though they increased the height. They did all of this knowing there were people and families downstream of the dam. When increasing the height of the dam and not increasing the width along with it one comes into the issue of overturning being a possibility. Another thing that was not looked into was if the soil where the new water height would be going would be sufficient enough to hold itself in place if a several cycles of drawing the water up and down were to occur, rapid drawdown. The engineer that was in charge of the dam had done many dam projects before and thought that this one was no different and all the problems that arose were of no concern to him. This is where he had no integrity towards his work. He also did not think of the families that were downstream of the dam and would really be affected by the dam if it were to break. When the dam did fail, roughly 431 people died. The force of the water that came from the dam when it did fail caused chunks of the dam to go up to a mile downstream, some pieces were not found when inspectors tried to go and reconstruct the dam. The failure of the dam…
