- Coastal protection strategies
- Hard engineering
- Sea walls
- coastline shielded by a solid steel concrete with lip at top to throw waves backwards.
- Cliff fixing
- dividing iron bars into cliff face to stabilize lose rocks and absorb power of waves.
- Rip rap
- Large boulders dumped in-front of a cliff taking force of waves.
- Gabions
- Small boulders in a steel mesh absorbing wave energy at a cliff
- Groynes
- Wooden or steel breakwaters, right angle to waves preventing sediment movement slowing LSD.
- Barrages
- partly submerged wall with sluice gates controlling water flow.
- Expensive... in one place have consequences. visually impairing.
- Sea walls
- Soft engineering
- Dune regeneration
- replace vegetation. selective grazing. Fence off areas. provide walkways. tourist info.
- Managed retreat
- Abandoning current line, and developing exposed land. Creating salt marshes are itself own defence.
- Do nothing
- does it need to be protected? need to compensate those affected.
- Regular maintenance. less able to cope with long term extreme events.
- Dune regeneration
- Hard engineering
