Sea Palling- Norfolk case study Flashcards
what are the cliffs made from?
soft rock=more vulnerable to wave attacks
what happened in 1953?
storm surge broke through sand dunes and flooded parts of NE Norfolk
what happened in 1991?
temporary rip-rap put in front of sea wall until permanent fixtures were put in place
over 100,000 tonnes of boulders placed in front of sea wall
prevent collapsing and reduce wave energy
beach replenished with 1 million cubic cm sand
widens existing beach and reduces wave velocity
off shore bars parallel to coast have been built
break waves before they reach the beach and gaps allow longshore drift to continue=TOMBOLA EFFECT
social effects
- no loss of property
- no loss of historic sites
- no loss of recreational use e.g. car park/beach
environmental effects
- no loss of dunes behind sea wall
- no landscape changes
