3. Human action- Some strategies can rob sediment from beach.

Question 3

• Drainage pipes in cliff and shrub planting- drains cliff and roots of plants bind cliff together.

• Beach feeding- Best natural defence/ expensive
• Groynes- build up sediment/ reduces sediment elsewhere/ expensive.

Question 4

What are the different strategies for the community to deal with the cliff erosion?

Answer 4

• 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.
