A groyne is a structure which is built at least partially underwater to inhibit water flow and control the movement of sediment. The purpose of a groin at the beach is either to create more beach or to prevent the erosion of an existing beach.
The purpose of groynes are to provent long-shore drift.
what is the purpose of a groyne
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.
Compare and contrast seawalls and groins
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
These two terms are often used interchangeably to refer to the short, shore perpendicular structures that are built along a shoreline to hold sand in place. However, technically speaking, groins and jetties are not the same thing. Groins are the smaller shore perpendicular structures, built to trap sand and stabilize a sandy beach. Jetties are large structures typically used to stabilize inlet channels.
channel surfed lol :)
Groyne
A beach groyne works when you put a groyne on the water (usually made of timber, bamboo, or other materials), the only source for a groyne is so that the whole beach/island doesn't "wash away" and all of it's sand get washed off into the ocean.
A build-up, which is often accompanied by accelerated erosion of the downdrift beach, which receives little or no sand from longshore drift. (This is known as terminal groyne syndrome, as it occurs after the terminal groyne in a group of groynes).

A Groyne can cost up to about £5000. Hope This Helps x GEOG 2 BOOKS FOR SCHOOLS x

Danny's job on Falcon Beach was that of an Arcade Manager.
a single groyne cost about £5,000 per metre http://www.mjanderson.chislehurst.btinternet.co.uk/coastseadefence.htm this is where find more of the cost of sea defences :D
its a concreete stuchure to protect the cliffs from erosion
Seashells are not alive, so they do not have a job they just sit there on the beach and do nothing.
The groyne has many features that make it useful. Gyrones can be designed however a person wants it to be designed, which makes it as permeable or nonpermeable as they want.
