- Coastal recession
- Consequences
- People may need to relocate homes or businesses
- property in this area significantly drops in value e.g Skipsea
- 2014 damage to SW railway line led to 2 month closure & losses of £1.2 billion to local economy
- The Maldives is one of the lowest lying countries in world - at risk of being fully submerged. rely heavily on tourism, destruction from flooding threatens this. many peopl migrate away from annual flooding
- Defences
- Hard engineering
- groynes £, creates wider beaches, but starves sediment cells up coast.
- rip-rap/rock armour £, long lasting, can be a hazard for pedestrians
- sea wall £££, long term & low maintence, create strong backwash which can undercut base
- offshore breakwaters £££, create calmer waters behind it, can change wave patterns
- revetments ££, constant maintenance, break down force of waves before hit coastline
- Soft engineering
- beach nourishment ££, maintains beach for tourism, unsustainable
- dune stabilisation - creation/ restoration. beach nourishment/ vegetation - natural barrier & habitat - protects only a small area
- cliff re-grading
- Hard engineering
- Consequences
