What is the second largest dam in the world?
Actually, the world's second largest dam is in Fort McMurray, Alberta, Canada. The dam holds back approximately 50 square kilometers of tailings from oil sands refining. If this dam were to burst it would cause the total destruction of the local ecosystem, as well as making the surrounding groundwater useless due to the presence of toxic heavy metals, and other known carcinogens.
Why are dams built on fast flowing rivers?
A river may be dammed to provide a reservoir for drinking water, or for producing electricity. A dam could also be built to regulate water flow, hold back water during drought, or slowly release water during heavy rain.
Why are dams built near river?
it is bcoz in a hydroelectric power station, fast flowing water spins the turbines. On a wind farm, the wind turbines spin due to fast wind and in the sea, in the sea, waves and the tide can be used to make a turbine spin.

What are the benefits o hydroelectric dams?
One of the advantages of a hydro powered dam is that the energy it produces is considered renewable. This means that power can constantly be created because the fuel source will never run out. Another advantage is that they can be built wherever there is a large body of water.
Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
Dams hold back water up to the level that they were designed for. They control/regulate the flow of water. Flood waters that come down rivers can be held back (up to the design point) from devastating places further down river. Coastal/sea flooding would not be stopped by dams - but sea walls and the like. Still, preventing river flood waters adding to coastal flooding might help the situation.
How did the Hoover Dam affect people?
It provided jobs during the depression, it provided a water reserve that spurred growth and agricultural irrigation, it provided cheap hydroelectric power, it ended flood damage and it provided a mighty fine recreational fishing hole.
