(Dân trí)-catering to the production of electricity and provide water for irrigation, the many hydroelectric dams large capacity vy heroes have been built in many countries of the world.
Three Gorges Dam, China
Three Gorges Dam North of the Yangtze River in horizontal Hubei Province of China, is the world’s largest power plants of capacity (22,500 MW).
The dam was built with concrete and steel with a height of 181 meters and the reservoir stretches 610 km. More than 102,600,000 cubic metres of Earth had to be moved to make way for 27.2 million cubic metres of concrete and 463,000 tons of steel, enough to build 63 Eiffel Towers. Costs spent to build the dam up to 22.5 billion dollars.
The water level of the dam height maximum of 175m above sea level, the higher the water level downstream river 110 m, the reservoir has a length of about 660 km wide and 1.12 km. The reservoir has a volume of 39.3 cubic kilometers and a total area of water surface 1045 km2.
Itaipú, the border of Brazil and Paraguay
Itaipú Dam is located on the Paraná River between the border of Brazil and Paraguay. Though the dam has a capacity of 14,000 MW-is lower than China’s Three Gorges Dam but have a higher annual output when it reaches the average yield from 91-95 TWh of electric power (compared to 80 TWh of power of the three Gorges Dam).
The total length of the dam 7,235 m. To this massive construction, the River Parana (World’s largest) which means vast ocean to flow changes with 50 million tons of Earth had to be moved.
The amount of concrete used to build the dam under estimate enough to build 210 stadiums and 380 Eiffel Tower and land mass of stones were dug to build the Itaipu Channel tunnel produce 8.5 times. The dam provides 90% of the power consumption for Paraguay and 19% for Brazil.
Guri Dam, Venezuela
The dam has a length of 162 metres high, and 7,426 housed in Venezuela on the river Caronni. As of 2009, this third-largest hydroelectric dam in the world, with export 10,235 MW. Guri dam provides own 73% of electricity for Venezuela.
The Guri dam building controversy in a very long time because it changes and heavy influence to ecosystems and biological diversity of the surrounding forests.
Tucurui Dam, Brazil
Tucurui, Brazil-hydroelectric dam is a concrete gravity dam on the Tocantins River is located in the District of Tucurui, Brazil. The main part of the Tucurui dam 78 m high and 6.9 km long. Part of the dike and the Caraipé Mojú land increased the total length of 12,515 m.
Tucurui dam brought electricity to 13 million people and 60% of the electrical service in the industry to create a maximum of 2,000 jobs jobs. But the construction of the dam also attracted a large number of people migrated to this area lead to deforestation and many other negative effects.
Grand Coulee Dam, United States Of America
Grand Coulee is a gravity dam on the Columbia River in the U.S. State of Washington of the United States of America was built to produce hydroelectric power and provide irrigation.
The dam was built between 1933 and 1942, initially with two power plants. A third power plant was completed in 1974 to increase its energy production.
This is the basis of the largest electric energy production in the United States and one of the largest concrete structure in the world. Through a series of upgrades and installation of pumps, generators, we had 4 dam power plant with capacity of 6809 MW installation. The reservoir supplies water for irrigation of 671,000 acres.
Sayano-Shushenskaya Dam, Russia
Sayano-Shushenskaya dam is located on the Yenisei River, near Sayanogorsk, Russia. It is the largest power plants in Russia and is the sixth-largest hydroelectric plant in the world.
The dam was constructed very securely with the ability to withstand earthquakes up to magnitude 8, and was enrolled into the world record books with titles that hydroelectric dams solidly for the world.
Longtan Dam, China
Longtan dam located on the Hongshui River in Tian’e County in China. The High Dam 849 meters long 216.2 m and is beating “RCC (RCC) gravity dam” highest in the world.
