What happens to a beach when a groin is installed?
A groin is an obstruction, usually a concrete or rock wall, built perpendicular to a beach to inhibit sediment removal by littoral drifting while the input of sediment from littoral drifting remains the same. This obstruction, however, starves the adjacent, downcoast beach area of material input while the rate of sediment removal from that adjacent beach does not change. The end result is that beach sediment will build up on one side of the groin, and be eaten away on the other side.
