When a dam is there in a stream, one side of the water will be very full and there is a lot of space in the next side. And there will be a lot of pressure from the water and it will go faster and faster with lots and lots of pressure and then when the dam opens, the turbine spins very fast. And all the water will go to the other side and there will be no overflowing going on. A dam is a structure that blocks the flow of a river.
Some dams divert pipeline, canal or a channel. Others aise the level of inland. Waterways to make them navigable by ships and barges. Many dams harness the energy of falling water to generate electric power.
Dams also hold water for drinking and crop irrigation and provide flood control. The oldest known human-being made dams were built more than 5000 years ago in arid parts of the Middle East to divent river water to irrigate crops.
Many modern dams serve 2 or more purposes. For example the TVA designed and built dams along the Tennessee River and its tributaries to provide flood control, generate electric power, and control river levels to permit years round navigation.
A dam can block any flooding which is going on only in waterways. And it can also be changed into drinking water.
