A groyne is a hydraulic structure that is used to interrupt water flow and to keep sediment from moving. Groynes can cost up to $770,000.
Groynes are placed so as to reduce coastal (or riverside) erosion.In the coastal case, they interrupt the flow of sediment along the coast, and accumulate it alongside the groyne.
