- Holderness- hard and soft engineering
- Soft Engineering: schemes set up using knowledge of a river and its processes to reduce the effects of flooding
- Causes- human:
- coastal defences e.g. groyne at Mappleton stopping longshore drift moving down the coast= beaches are narrower and more easily eroded
- Hard Engineering: man made structures built to control flow of river and reduce flooding
- Causes-physical:
- rock type: boulder clays=easily eroded
- narrow beaches give less protection from the waves
- prevailing wind= hits coast directly
- waves have long fetch= very powerful
- Responses
- groynes: Mappleton
- rock armour: Mapleton
- sea walls and wooden groynes: Hornsea
- Impacts
- loss of land, building, roads
- loss of coastal habitats and scenery
- 80,000 sq-m of farmland lost per year= huge effect on farmer's livelihoods
- slumping of material onto beach
- business at risk and people may lose their jobs
- roads at risk of falling into the sea
