- Holderness Coast
- Defense Strategies & Their Success
- Following a massive breach in 1849, groynes and revetments were erected to stabilise Spurn Head.
- However, the maintenance soon become too costly and the sea defenses fell into disrepair.
- Important parts of the coastline have been protected by hard engineering strategies such as sea walls, rock armour and groynes.
- Although this has ensured the protection of the important areas (tourist towns Hornsea and Mappleton), they have deprived other areas further south of sediment, furthering erosion.

- Processes & Landforms
- Flamborough Head: - a headland - formed because of its chalk makeup - has many 'faults' caused by weakness in the chalk and exploited by weathering and erosion - often experiences rockfalls as erosion undercuts the base of the cliff
- Bridlington Bay: - has retreated up to 5km since Roman Times - much of its sediment is transferred to Spurn Head via longshore drift
- Spurn Head: - a spit (landform of deposition) - has frequently been breached and destroyed during storms
- Factors Affecting the Coastline
- Geology: Holderness coast is made up of glacial till and aluvuim (soft rock) and chalk (hard rock). However, both these rocks are easily eroded.
- Wave power: waves that hit Holderness coast have a very large fetch - they have travelled a long way and this means they are incredibly powerful and destructive.
