Hydroelectric is the most common alternative energy source currently in use in the world. A hydroelectric dam is complex and hard to set up. To create a hydroelectric plant‚ it typically takes a large river with a steep drop in elevation. The greater the drop and amount of water‚ the more electricity is generated from the greater potential energy the water has when it’s higher up. At the bottom of the a dam‚ there is an intake where gravity forces the water in and through a section called the penstock. The

Hoover’s dam is one of the main reason why the irrigation changed Yuma/Southern Arizona. Hoover Dam control the Colorado River water. The colorado river is the main source of water used to irrigate crops‚ and when it over flows it destroy the crops and yuma will be filled with water. Which is when Hoover dam came and it can help control the flood. “Lives and property formerly at the mercy of the unbridled river are less likely destroyed by destructive floods.” The Hoover Dam is able to do much more

Kalabagh Dam: the question of alternatives THE rush to build the Kalabagh dam is taking General Musharraf and many of his supporters‚ including some born-again superpatriots‚ to heights of irrationality. As if the doctrine of necessity‚ which has provided the alibi for all military coups since the original one of Ayub Khan‚ was not enough‚ a new and much more sinister doctrine‚ that of indispensability‚ is being promoted. Its purpose is to justify the indefinite continuation of the present

Research on the Three Gorges Dam Summary This report aims to investigate into the Three Gorges Dam (TGD) project in terms of its backgrounds and development. Focusing on the examination into the sustainable development of the TGD‚ this report also intends to reveal controversies facing the TGD and present cost-benefit analysis to the TGD. Introduction Water resource management has been in China’s history for thousands of years with the starting point of the Dujiang Dam‚ which is still working (Lei

The Colorado River Geographers can tell you that the one thing that most rivers and their adjacent flood plains in the world have in common is that they have rich histories associated with human settlement and development. This especially true in arid regions which are very dependent upon water. Two excellent examples are the Nile and the Tigris-Euphrates rivers which show use the relationship between rivers and concentrations of people. However‚ the Colorado River is not such a good

pH Readings: From the pH results recorded from the two water sources‚ we can clearly see that Kleinfontein Dam has the higher pH levels‚ which indicate poor and unsafe water conditions. From Article two‚ we can see that a High (7.5) or Low (5.5) pH level is very dangerous and harmful to humans who come in contact with the water. The pH Level recordings at 8 and 9 are extreme dangers if they were to come in to contact with humans and also they are way over the borders which is not acceptable at

The River as Bridge At the beginning of the new millennium urban populations outnumbered that of rural populations for the first time in history. Urban areas have long had connotations of being harmful to our environment and the people living in them are often seen as either careless or oblivious in regards to maintaining their surrounding environment; most notably the rivers that flow through their cities. The Trinity River begins in North Texas and flows all the way to the Gulf of Mexico; it flows

When the Elwha Dam was demolished it was the largest controlled sediment release in a dam removal project anywhere in the world. Because of the amount of sediment behind large dams like the Elwha‚ the demolition must be done gradually over time to ensure that there is not an overflow of sediment rushed down the river which could cause significant damage to the landscape and the organisms which inhabit it. At the time of the dam removal the Elwha was holding behind it 15‚000‚000 cubic yards of silt
