What else can I help you with?
Hydroelectric dams use the kinetic energy of water to produce electrical energy What is the environmental drawback of building hydroelectric dams?
One environmental drawback of building hydroelectric dams is the disruption of river ecosystems, including changes in water flow, sediment transport, and fish migration patterns. Dams can also lead to reduced water quality downstream and the displacement of communities and wildlife due to flooding of land for reservoirs.
What are the potential consequences of water dams breaking?
The potential consequences of water dams breaking include flooding, destruction of property, loss of life, displacement of communities, and environmental damage.
Two lakes of equal depth are dammed on lake backs up 15km and the other backs up 30km What is the difference in pressure on the dams?
This question is set up to trick you. You don't need to know how much water surrounds the dam, because it is irrelevant. Assuming the atmospheric pressure is the same for both dams, depth is the only factor that affects fluid pressure. It's simply evaluating your knowledge of basic hydrostatic principles. So, for any depth, these two lakes have no difference in pressure.
How abundant is hydroelectric energy?
Hydroelecticity is very abundant and is considered a renewable resource because it will never run out. Many hydroelectic dams have be built in areas that aren't necessarily on a major river. But rivers have been diverted into man made reservoirs to create water pressure.
Two dams form artificial lakes of equal depth. however one lake backs up 15 km behind the dam and the other backs up 30 km behind. what effect does the difference in length have on the pressure on the?
Careful! This is a tricky question. When we're talking about the pressure on the dam, we only really care about the depth of the lakes, not their lengths. The answer is that the length of the lakes makes no difference on the pressure exerted on the dam. Thanks Mr. Sacks!
What is a characteristic of Lowhead dams?
Low head dams pose hazards both above and below dams.They pose hazards both above and below dams
Why are Lowhead dams dangerous to small boats and paddle craft?
Backwash can pin you and the boat indefinitely.
What major hazard is created by low -head dam?
Low-head dams are dangerous because people fail to realize that these dams are just as dangerous as larger dams. The movement of the water at the base can pull people under and trap them. These low-head dams have been nicknamed 'drowning machines.'
When was World Commission on Dams created?
World Commission on Dams was created in 1998.

Why would people in south America be likely to build dams on the major rivers?
People in south America build dams on the major rivers to get more electricity. Plus, there is more industrialization in the area.
