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.
With a buttress dam, the face of the dam is held by a series of supports or buttresses that are placed at intervals on the downstream side. The buttresses work to combat the force of reservoir water from trying to push the dam over.Sugar Hollow Reservoir Dam-White Hall, VA.s a result, this type of dam is also referred to as an Ambursen dam.
