Protecting the coast.

HideShow resource information

Geography revision on protecting the coast.

There are many methods used to protect the coastline from the powerful effects of the water.

Groynes- A groyne is a wooden fence that is positioned at a right angle to the beach, they run the length of the beach and seperate it into sections. The way they protect the coast is that they trap material from longshore drift so that the beach material is not being pulled back into the sea. The only problems with Groynes are that after a while the wood will start to rot because it is in the water for alot of the time, they will then need replacing. An example of where a Groyne can be seen is Blackpool.
