Study Notes

The Holderness Coastline

  • The Holderness Coastline in East Yorkshire stretches 61km from Flamborough Head in the north to Spurn Head in the south.
  • The coastline's geology is composed of boulder clay, chalk, and alluvium, which contributes to its rapid erosion.

Geology of the Coastline

  • The main rock of the coastline is boulder clay, deposited after the ice age as the glaciers melted with the material they had picked up off the sea bed.
  • The coastline has eroded about 4km since Roman times, retreating around 1-2 meters per year.
  • Flamborough Head is made of white chalk.

Key Locations

  • Flamborough Head: composed of resistant white chalk, eroded to leave a headland due to hydraulic action, bedding planes, and joints.
  • Barmston: area of weak cliff due to mud and dried sediment, prone to erosion, with a failed attempt to protect the caravan park using boulders.
  • Hornsea: a tourist town relying on income from tourism, with multiple caravan parks, golf clubs, arcades, and a promenade.
  • Hornsea's Protection Methods: includes sea wall, rock armor/riprap, and groynes to reduce longshore drift.
  • Hornsea's Beach: crucial for tourism, but threatened by terminal groyne effect and erosion, which accelerates erosion further down the coast.
  • Easington Gas Terminal: a small village protected due to the strategic importance of the gas terminal, which supplies gas from the North Sea.
  • Spurn Head: a salt marsh area to the west, serving as a bird habitat, with a lifeguard station, lighthouse, and small settlement, but with abandoned defenses.
