  • Retreating clay cliffs of the Holderness Bay (middle)

  • 6km spit at Spurn Point (south)

New cards

Flamborough Head


  • Highly permeable 

  • Hydraulic action 

  • Hydraulic action, weathering and mass movement combined can form wave cut platforms

  • Wave refraction causes notches, arches, caves, stacks and stumps

Holderness Cliffs

  • Made from easily eroded boulder clay

  • Retreating by 1.8m/y

  • Rain causes land slides 

  • Fine clay removed by longshore drift (carries half a million tones of sediment - suspension - per year)

  • Winter storms threatening

Spurn Head

  • Longshore drift 

  • 6km long

  • Growing 10cm/y

  • Winter storms threatening

  • Home to sand dunes and salt marshes
