COASTAL RECESSION

Coastal recession is having an effect on the coastline of the UK.

The amount of effect is determined by the land use.

If the area suffering from cliff recession is used for settlement, the effect is greater than if the cliff recession is affecting farmland, which is seen to be less important as it is not worth as much money.

The effects of coastal recession can be seen all around the coast of the UK.

DEFENDING THE COASTLINE

Two ways we can defend the coastline are:

Examples of how we can defend the coastline are:

MANAGEMENT OF COASTAL RECESSION AT WALTON-ON-THE-NAZE.

•Walton-on-the-Naze is a coastal town in Essex. It suffers from coastal erosion due to the types of rock which make up the cliff.

•The rock types are London Clay and Red Crag and both of these rock types are easily eroded by the sea.

•The cliffs also suffer from slumping which makes the defence of the area even more complex.

•Longshore drift moves sand along the coastline from south to north.

• All of these factors must be considered when deciding the type of management that will be effective in an area.
