Protect historic landmarks

Rock Amour Expensive Erodes after a while

Holds beach material in place

Revetments Doesn’t stop cliff face erosion

Sea Wall Can lead to undercutting Expensive

Can be used for leisure activities It deflects the waves

Groynes Stops longshore drift

Builds beaches Slows cliff erosion

Offshore Breakwater

Stabilising Sand Dunes

Planting the grasses could take time The paths would have to be maintained

A flood barrier is created Footpaths prevent trampling Provide habitats

Management Retreat

Could eventually erode the roads nearby

Doesn’t interfere with nature
