Why this matters:
Understanding coastal management is crucial for protecting communities, preserving ecosystems, and maintaining economic stability in coastal areas.
Why is the management needed?
Why is the management needed?
Rock type - the cliffs are made from less-resistant (soft) boulder clay which slumps when wet.
Naturally narrow beaches - these beaches give less protection to the coast as it doesn't reduce the power of the waves.
Man-made structures - groynes have been installed to stop long-shore drift. This makes unprotected beaches narrower and accelerates erosion
Powerful waves - waves at Holderness travel long distances over the North Sea (so have a long fetch) which means they will increase in energy.
What management strategies are being used?
What management strategies are being used?
Bridlington is protected by a 4.7 km long sea wall.
Hornsea is protected by a sea wall, groynes and rock armour.
Coastal management at Withersea has tried to make the beach wider by using groynes, and also uses a seawall to protect the coast.
Mappleton is protected by rock groynes.
Spurn Head is protected with groynes and rock armour.
What conflicts have arisen from the management?
What conflicts have arisen from the management?
There has been an increase in erosion at Great Cowden because of the groynes used in Mappleton. This has led to farms being destroyed by the erosion and the loss of 100 chalets at the Golden Sands Holiday Park.
Different stakeholders disagree about the placement of costal protection, especially if it means the land in their community is not protected.
Some sea defences negatively impact tourism and reduce the amount of money coming in to the area.
Common misconceptions
Common misconceptions
Misconception: Sea defences always stop erosion.
Reality: They often just transfer the energy down the coast
Misconception: It is possible to protect the whole coastline
Reality: Protecting coastlines costs many millions of pounds. Protecting coastlines is often a difficult decision.
Summary
Summary
The Holderness Coast faces rapid erosion due to its geological composition and environmental factors.
The Holderness Coast management employs various strategies to combat erosion, with mixed success and some unintended consequences, highlighting the complexity of coastal management.
