Engineering Marvels: Three Mega Dams - Three Gorges, Hoover, and Grand Coulee

The Three Gorges Dam in China harnesses the power of the Yangtze River, producing 5 million times more power than Debton.
The dam consists of 32 generators, each producing as much electricity as a small nuclear power plant, and together they provide power for 60 million Chinese.
The Three Gorges Dam is the largest hydroelectric project in the world, almost twice the size of the next largest project in Brazil.
The French built the Mirage Dam in 1878 to generate electricity on a larger scale, diverting the Dordoin River and producing 128 megawatts.
The Hoover Dam in the US was built in the 1930s to provide water and power to cities in the Western United States.
The Hoover Dam contains six million tons of concrete and took 125 years to finish shrinking and cooling down naturally.
To expedite the cooling process, the dam's chief engineer, Frank Crow, embedded water pipes into the concrete and used chilled Colorado River water to cool it down.
The Grand Coulee Dam in the US was built to withstand the destructive power of overflowing water, following the catastrophic Johnstown Flood in 1889.
The Three Gorges Dam contains more concrete than any other structure on Earth, with a colossal amount of concrete at the base and a length of two kilometers.
Chinese engineers implemented various cooling measures to prevent cracks in the dam, including cooling aggregates, adding ice, and using a fog spray system to block solar radiation.
The Three Gorges Dam required the relocation of over a million people and the construction of thousands of new houses for the displaced citizens.
The Three Gorges Dam presents logistical challenges due to the flooding of over 150,000 acres of land along the Yangtze River's banks.

Test your knowledge on three of the world's most impressive dams - the Three Gorges, Hoover, and Grand Coulee. Discover fascinating facts about their construction, engineering feats, and the impact they have had on the surrounding areas.
