Hoover Dam attracts over 7 zillion visitors from around the new world every year nutriment vast tourism into the Las Vegas Nevada and Arizona economy.The building of Hoover Dam took the grandeur of over 200 engineers to pull-off what many deemed as almost impossible. And it was the endurance of over 7,000 dam workers that endured amazingly harsh conditions and extreme dangers to complete Hoover Dam almost two years ahead of scheduleThe relegation of the Dam 1.Flooding alon g the Colorado River as it made its authority to the Gulf of California had to be controlled. 2.The water-flow had to be harnessed to provide very much needed water to the fertile, yet arid agricultural areas of California and Arizona. 3.hydroelectric energy was to satisfy the requirements of millions and millions of people in adjacent regions.Some Statistics most the dimensions of the damHoover Dam is 726 feet tall and 1,244 feet long. At its base, Hoover Dam is 660 feet thick which is 60 feet longer than two football fields set end-to-end. Combined with its top thickness of 45 feet, there is enough concrete (4.5 million cubic yards) in Hoover Dam to build a two-lane highway from Seattle Washington to Miami Florida. Or imagine a four-foot good sidewalk around Earth at its equator.A scenic by-product of Hoover Dam is the gigantic reservoir of Lake Mead, a stunningly dishy water recreation wonderland. This boating, sailing, fishing and house-boating paradise attracts over 10 m illion visitors a year. Lake Mead covers 550 miles of majestic shoreline and 247 square miles of area which is twice the size of Rhode Island. Its efficacy of 1 1/4 trillion cubic feet of water would cover the entire state of Pennsylvania one foot deep.Requirements for concrete posed by Structural designThe Hoover Dam is an arch dam. wet dams transmit most of the horizontal thrust of the water stored behind them to the abutments by arch action and hence thinner cross sections are adapted (compared to the massive cross-sections of the gravity dams). Narrow V-shaped outhouseyons(just like the Black canyon where the Hoover dam was constructed) will be suited for locating arch dams since they can withstand the thrust produced by the arch section.
