Study Notes

Mega Dams: Engineering Marvels

The Three Gorges Dam and the Hoover Dam produce 5 million times more power than Debton.
The Three Gorges Dam harnesses the power of the Yangtze River, with its reservoir rising 60 stories above the riverbed.
32 generators at the Three Gorges Dam produce enough power for 60 million Chinese, setting a new benchmark in the hydroelectric industry.
In 1878, Debton Dam showcased the potential of harnessing electricity from small streams, while French Engineers diverted the Dordoin River to build a 128-megawatt dam during World War I.
The Mirage Dam in France produced 128 megawatts, aiding in powering a train line and supplying Paris with electricity.
The Yangtze River, the largest in China, presents immense logistical challenges for dam engineers.
The Three Gorges Dam necessitated the relocation of over a million people and the construction of thousands of new houses.
American Engineers building the Hoover Dam mitigated concrete cooling challenges by casting it in small blocks and using river water to expedite the cooling process.
The Hoover Dam, with 6 million tons of concrete, stored 35 billion cubic meters of water and generated more power than any other dam at the time.
The Three Gorges Dam contains more concrete than any other structure on Earth, requiring innovative cooling measures to prevent cracking.
As dams grew, they held back more water, necessitating protective measures, as seen in the construction of the Grand Coulee Dam.
The catastrophic effects of the Johnstown, Pennsylvania flood in 1889 prompted American Engineers to develop protective measures for larger dams.
