Coastal Management
- Hard Engineering
- Sea walls - concrete walls that are placed (expensive but effective)
- Rock armour - boulders at the bottom of cliffs to get most of the impact (expensive to transport but cheaper than sea wall)
- Groynes - wooden or rock structures built at an angle to the sea (unattractive but builds beaches
- Soft Engineering
- Beach Nourishment - placement of sand onto beach to build it up (constant replacement but blends with existing beach)
