Nothing, Its still water. Boats and animals swim around the dam. So the water stays the same!
In addition to its use in agriculture, the water stored in lakes created behind dams is also used to generate electricity.
How do dams disrupt the surrounding aquatic life it stops flow of the water and fish cant migrate and if that happens the the food chain goes down from there
Dams cause floods if they break. One purpose for a dam is create a lake behind it, so if it breaks or even leaks badly, the water behind the dam flows out faster than the stream bed below the dam can handle, The water overflows the banks of the stream and a flood occurs.
That would be water. Water from rivers being very popular with the hydroelectric dams. Storing its potential energy behind the dam.
Humans build dams primarily for flood control and for the generation of power. As a side benefit they create lakes. Dams also can provide more workers and a better habitat for blad eagles during the winter.
Beavers build dams that stop the flow of water. When this happens, the wildlife in rivers suffer because the flow of water stops.
of course not ! dams need water as the energy to create electricity. Basically water is fuel to create electricity in dams and without it, it is impossible if there isn't any other form of fuel energy provided to dams ...
It holds water behind it as potential energy. The difference in the pressure of the water between the reservoir and the turbine outlet make power. Some dams pump water back up behind the dam when power consumption is low.
electricity dams/hydro dams
hydroelectric dams
Water dams are blocks put on river and lake routes to stop the flow of water and corner it to be used for useful purposes.
Storing water in reservoirs and behind dams, allows us to have water for domestic and industrial use throughout the year and, in hydro-electric schemes, the production of electricity.
