Groynes, columns of boulders and sea walls are the most popular ones. sea walls are the most expensive, costing about 700,000 pounds per metre!
wellthey are called defenses and this is because a river starts in a mountain and ends at the sea wellthey are called defenses and this is because a river starts in a mountain and ends at the sea

The sea defenses at Mappleton in the UK were built in 1991 as a response to coastal erosion threatening the village and its farmland. The defenses consist of rock groynes and a mass concrete seawall to protect the coastline from erosion by the North Sea.
To prevent coastal erosion.

It may fall into the sea, but the likelihood is that the sea defenses will be maintained adequately.
you need sea defenses to keep unwanted vessels (boats, submarines, etc.) out.
there is sea defenses at Walton there's the tower breakwater, the sea wall, the groynes etc these are all coastal defenses. and its not that the council wont pay for it its because if the protect the cliffs at Walton they would ruing other nearby towns such as frinton and happisburgh. Walton is also the only place (world wide) in which you can find the left handed whelk!!! even if you protect the coast you are just slowing it down NOT STOPPING it completely! the council need to get planning permission to put sea defenses in the and that will take a long time to get !! hope that helped you samii x
All living things have defenses, yes.
there has been a sea wall built out to sea, but this has increased erosion ferther down the coast.
1 is a groyne which absorbs some wave power and catches sediment. another is a sea wall which deflects wave force and pushes it out to sea. i dunno any others I'm trying to find that out my self at the moment! lol
