1
Q
A case study of:
A
- Landform management scheme
- landforms affecting people’s activities.
2
Q

A
- Geology is weak- Clay intercepts water and ponding occurs.
- Weathering- Freeze thaw action,storms,waves,winds.
- Human action- Some strategies can rob sediment from beach.
3
Q
What strategies are made to manage landforms?
A
- Timber resentments- Break power of the wave/ expensive/ short life.
- Drainage pipes in cliff and shrub planting- drains cliff and roots of plants bind cliff together.
- Sea walls- reflect power of the wave/expensive
- Gabion cages support base of cliff; ugly; cheap
- Beach feeding- Best natural defence/ expensive
- Groynes- build up sediment/ reduces sediment elsewhere/ expensive.

Q
What are the different strategies for the community to deal with the cliff erosion?
A
- Cost benefit analysis policy- If the land is 5x more than the defences will cost then they will protect the land.
- Managed retreat- low spending over a period of time
- red lining- council estimates where coast will be in 60 years time and doesn’t allow planing permission for anything on the seaside line.
- Holding the line- money spent on defences is a priority.
- let if fall- No money, let nature take over.
