- NORFOLK COASTLINE
- What makes it distinctive?
- Low-lying
- Range of habitats
- Salt-marshes
- Expanse of Sand dunes.
- Shallow gradient seabed= tide goes out a long way
- Sand dries out and it is blown onshore
- Expanse of Sand dunes.
- Sand dries out and it is blown onshore
- underlying rock is chalk
- Hidden by a layer of drift- laid down by advancing ice sheet.
- Ice sheet created a ridge near Cromer- highest point of the county - 100m
- Hidden by a layer of drift- laid down by advancing ice sheet.
- Landscape character
- Subdued relief
- people can appreciate big skies
- Growing tourism of night skies.
- people can appreciate big skies
- Flinty soils
- Coastal road follows slightly higher land- lies inland from marshes.
- Marshland- some near Holkham drained by Dutch.
- Windy beach one of the world's best beaches- extensive sand dunes.
- Subdued relief
- How does human activity effect geomorphic processes working on the coast
- Villages sit on slightly higher land- avoid coastal flooding
- 2013 flooding- Wells-next-the-sea and Blakeney
- Blakeney Point- spits formed. Boat activity popular for tourists- adds value and employment
- Lifeboat get a lot of calls in summer when people get stranded in hidden hollows
- Stiffkey- Saltmarsh developed- fine material trapped by specialist plants. Rare
- Good natural defence
- Holkham- dunes planted with pines- stabalise. Visitors encouraged ot use boardwalks than desirb marram grass and erode the dunes- lead to sand blowouts.
- Manage seat front at Wells-next-the-sea- groynes to protect beach huts and gabion baskets- slow down transportation
- Subject to erosion- whole villages wiped out in last century- Shipden, kewick, Wimpwell.
- Happisborough has become quite well known- retreat.
- Cley-nxt-the-sea- shingle ridges breached, large dunes stripped of sands. Sea Walls, rip-rap at sheringham and Gabion boxes at Branchester.
- Living Landscape- Cley-next-the-sea.
- provides home for wilflife, protects single ridge which forms base of Blakeney Point.
- A breach in this ridge could starve the spit of shingle and threaten its existence.
- provides home for wilflife, protects single ridge which forms base of Blakeney Point.
- Sea Palling
- protected- sea wall, offshore breakwaters have reduced intensity of wage action.
- Reduction of transportation of sediment = wide beach
- protected- sea wall, offshore breakwaters have reduced intensity of wage action.
- Happisbough
- Increased rate of erosion- unrepaired broken sea defence.
- Villages trying to claim compensation for damage to property.- threatened by receding coastline.
- Sea Palling- protected by sea efence scheme.
- Sea wall- reflect wave energy
- Offshore breakwaters- reduce intensity of wave action- reduce in erosion.
- Decrease in wave energy = reduction of sediment transportation = wide beach
- Villages sit on slightly higher land- avoid coastal flooding
