Coastal management

A 'hold the line approach' where defences are constructed to prevent or reduce erosion

Building defences which work with their natural surroundings to reduce and prevent erosion

Construction of man made coastal defences

Great expense to prevent any erosion from occurring by constructing coastline defences

Working with natural systems (e.g. beaches) to reduce erosion by absorbing wave and tidal energy

strategies such as sea walls, groynes and gabions

The reduce the power of the waves by causing them to break out at sea

They trap sediment by preventing longshore drift

Trapping sediment causes a beach to build up which provides a natural coastal protection, reducing a wave's available energy for eroding the cliff face

stopping any water from hitting the cliff face

Absorbing much of the waves energy

Working out the cost of something

Comparing the cost of a defence against the value of the area it would protect

If something should be built or not
