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.
