- Topic 4.4- Coastal case study, Holderness Coast
- About Holderness
- Stretches from Flamborough Head to Spurn Head
- Erosion is causing cliffs to collapse
- Cliffs are mostly made out of clay which is easily eroded (it's likely to slump when wet)
- Beaches are narrow so they don't offer much protection
- Longshore drift moves material South, exposing a new area of cliffs to erosion (coastline retreats)
- It faces the prevailing wind direction, waves from the Norwegian Sea
- Waves increase in power over the long distance so they are highly erosive.
- Parts protected by coastal defences (hard)
- There are towns and villages where people live and work
- Important infrastructure (B1242) links many towns and businesses along the coast
- There is a gas terminal which supplies 25% of UK gas
- Defences have causes problems further down the coast
- Groynes protect local areas but narrow beaches further down the coast
- Increases erosion e.g Great Cowden which has lots of farms and caravan parks
- Material produced from erosion transported down Humber estuary
- Reducing erosion and therefore its material risks flooding the estuary because there's less material to slow it down.
- Led to coastal retreat along other coasts because no new material is being added
- Reducing erosion and therefore its material risks flooding the estuary because there's less material to slow it down.
- Bays are forming between protected areas
- The protected areas become headlands which are eroded more heavily
- This makes maintaining defences in protected areas more expensive
- The protected areas become headlands which are eroded more heavily
- Groynes protect local areas but narrow beaches further down the coast
