Groynes prevent or slow down erosion.
Wooden groynes work belkhebra
Groynes are structures built along coastlines to control erosion and manage sediment transport. They help protect beaches by trapping sand, which can mitigate the impacts of wave action and reduce coastal erosion. Additionally, groynes can create calmer waters behind them, promoting the development of habitats for marine life. Overall, they play a crucial role in coastal management and preservation.
I know 2 advantages : The first advantage is that is lessens the effects of longshore drift on a beach. The second advantage is that is also builds up part of the beaches with the sand becoming deeper.

Groynes typically last between 15 to 30 years, depending on materials used, environmental conditions, and maintenance practices. Timber groynes may have a shorter lifespan due to deterioration from water and biological factors, while concrete or stone groynes can last much longer. Regular maintenance can extend their effectiveness and longevity.
They are cheap and they retain sand.

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

Yes, there are groynes on Dover Beach. Groynes are structures built perpendicular to the shoreline to trap sand and prevent erosion. Dover Beach, located in the southeast of England, has groynes as part of its coastal protection measures.
the advantages of rip rap are that it absorbs the waves energy and stops longshore drift ( like groynes) the disadvantages are that it costs alot for the granite boulders ( rip rap) to be transported! hope that helps :D
