at the beach!
Having studied the aerial view of Borth on Google Earth - there are groynes at regular intervals from Upper Borth to Ynyslas.
Wooden groynes work belkhebra
groynes are a fence or wall going into the sea to trap sand
Groynes prevent or slow down erosion.
Normal wooden groynes cost about five thousand pounds each. I am not entirely sure how much rock groynes cost though.
Stone groynes Wooden groynes and Sea Walls Hope this helped :')
They need groynes to prevent te sand going in land slides
A groynes is a hydraulic structure. It is build very sturdy so that it interrupts water flow on the ocean shore.
Groynes
there is about 7 groynes along dover beach. I think. sorry if this is wrong. if you know different CORRECT THIS
they dont
groynes are lke 20p each no this is a lie they cant be 20p i would go look somewhere else becuse i did this for my test and got no marks!
the Groynes protect the coast by stopping the long short drifts, it also stops the sand from moving into the sea instead of the coast line.

nothing there rubbish

They don't. Groynes inhibit longshore drift. Longshore drift occurs when currents develop parallel to a shoreline as a result of wave action, carrying sediment with them. Groynes catch sediment and interfere with these currents. Continental drift, a part of plate tectonics, is a completely unrelated process.
to stop long sure drift
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.
They slow it down.
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.
The purpose of groynes are to provent long-shore drift.
Groynes, sea walls and rip-raps
A groyne is a type of breakwater or jetty, which projects from the shore of a coast or river to block the movement of sediment. In rivers, they are called "wing dams" or spur dykes, and channel water into a faster-moving channel, usually in the center of the river. Groynes are used along beaches to prevent the removal of sand, or conversely to prevent the deposition of sandbars along shore.
