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. They are only temporary, though with a life of decades.Riverside groynes rely upon their mass to prevent current erosion of the riverbank. They will not usually accumulate sediments in any great quantity.Read more: How_do_groynes_work
