Wing dam in a man-made river bed. A wing dam or wing dike is a manmade barrier that, unlike a conventional dam, only extends partway into a river. These structures force water into a fast-moving center channel which reduces the rate of sediment accumulation while slowing water flow near the riverbanks.
Dams produce hydroelectricity, and the step to creat that, is very easy. What you need to build a dam is a river with a large drop in elevation-such as a waterfall.The dam stores lots of water behind it in it's reservoir-or a lake-type thing as a result of decreased water flow.Near the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.In the tunnel, the water flows down a large drop-called a penstock-and gravity causes it to gain speed.ear the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.
