The Three Gorges Dam is a model for disaster, yet Chinese companies are replicating the model. Huge hydropower cascades have been proposed and are being constructed in some of China’s most pristine and culturally diverse river basins. Around the world, large dams are causing social and environmental devastation while better alternatives are being ignored. It is the world’s biggest hydro project and the problems that come along with it are not unA third of China’s 1.3 billion people live in and around the Yangtze River basin. For centuries,
In 1928 Congress passed the legislation to pass the bill to build the dam. Other concerns to building the dam were the fact this was to be the highest concrete dam and largest building project that had ever been undertaken by the United States government. The project took six construction companies which created conflicts. The heat of Nevada sun with the lack of shelter was concern. Step Three-State the problem The main overall issue is who should get first call on the water and how should it be dispersed.
Three Gorges Dam 4/29/13 The Three Gorges Dam is a hydroelectric plant built on the Yangtze River in China. It’s the largest hydroelectric dam on Earth and can be seen in pictures from space. The dam has been the subject of controversy and dilemma since its construction. Raising numerous environmental, ethical and social dilemmas that question whether the pros of the dam outweigh the cons. Although the dam produces a huge amount of energy for China it has created many problems.
With reference to an area that you have studied, describe and explain the appropriateness of flood management strategies? (15marks) The Three Gorges dam on the Yangtze River in China can seem a very appropriate strategy of flood management however there are some negatives that show that is not a full proof strategy. The Three Gorges dam was built in 1994 to try and reduce major flooding in cities such as Wuhan and Nanjing. It is 101m high and as well boasts the largest hydroelectric power station in the world with around 26 turbines. Behind the dam is a reservoir which can hold up to 22km³ of water, this act as a catchment are for flood water.
The Three Gorges Dam INTRODUCTION The Three Gorges Dam is the world’s largest hydropower project and most notorious dam. The massive project sets records for number of people displaced (more than 1.2 million), number of cities and towns flooded (13 cities, 140 towns, 1,350 villages), and length of reservoir (more than 600 kilometres). The project has been plagued by corruption, spiralling costs, environmental impacts, human rights violations and resettlement difficulties. Flood Control: Since the beginning of the Han Dynasty 2,300 years ago, there have been 214 major floods recorded, averaging 1 flood every ten years. Within this past century, there have been five major floods that were recorded to have claimed hundreds of millions of lives, millions of acres of farmland, destroyed thousands of homes, and billions of dollars of damage.
The ship’s record-breaking length also meant that Lusitania would have to be launched diagonally. Lusitania was 787 feet long, longer than the river Clyde was wide. The shipbuilders took advantage of where a tributary met the river Clyde to maximize the length available for Lusitania to slide and float. Instead of the traditional method of shipbuilding where construction starts at both ends and meets in the middle, Lusitania’s construction started at the bow and moved towards the stern. The reason for this was actually because the plans for Lusitania’s engines and stern had not yet been finalized.
The Project The Three Gorges Dam stretches more than two kilometers across one of the greatest rivers in the world, the Yangtze. The dam was built in a stretch of the Yangtze known as Three Gorges because of the canyons formed by immense limestone cliffs. These gorges— the Xiling, Wu, and Qutang—offer some of the most scenic landscape anywhere in the world and have long been a destination spot for tourists from around the world. In recent years, tourism has boomed as people have rushed to see some of the sights to be destroyed by the dam and reservoir (China View 2008). The beauty of the region has inspired Chinese poets and artists for centuries including much of the work of Li Bai (701–762 AD), considered by many Chinese to be the world’s greatest poet (Fearnside 1988).
THE THAMES BARRIER On 31 January 1953 Britain and the Netherlands suffered one of the worst floods in their history. Huge waves battered the east coast, and a devastating tidal surge rushed up the Thames, with sea levels 3 metres above normal in some places. The flood destroyed London and covered 160,000 acres on Canvey Island and killed (drowned) 300 people in Essex. As a result of this, The Thames Barrier was built in order to protect the capital from flooding until the year 2030; however people suspect that global warming may predict the time and effectiveness of the barrier. The Thames Barrier is a unique construction and is the world’s largest movable flood barrier, spanning 520 metres across the Thames at Woolwich.
Choose a country where a water transfer scheme or a large dam has been created. Explain the advantages and disadvantages the shame has brought, or will bring, to the country. The project’s eventual goal is to move 44.8 billion cubic meters of water across the c Advantages | Disadvantages | | Diverting water hurts 2 most important rivers: the Han, the main source of water for about 30 million people, and the Yangtze, which runs through 11 provinces and supports up to 400 million people. | A slower-flowing river - slower at depositing the sediments along the riverbed which help mitigate pollution and nurture the river’s ecosystem. | A lower water volume - more saltwater from the sea filters into the Yangtze’s estuary.
This would, in turn, provide more land for farmers and help to eradicate their poverty issues. The Dam itself was built between Asyut and Abu Simbel, more towards the southern part of Egypt. While the Dam was intended to do nothing but benefit Egypt and its economy, it didn’t come without implications and negative effects. To build the Dam, many houses and residences had to be relocated and many people had to leave their homes. There were also old Egyptian structures that had to be carefully moved to avoid destruction from the new path of the river.
