North Norfolk Coast Case Study
About North Norfolk
In East Anglia
Low lying coastland
Broad sandy beaches
Salt marshes
Sand dunes
Cliffed coast line - In the east of Cromer
Famous for its big skies
Atracts a lot of tourists and artists
Geomorphic processes
Longshore drift operates from East to West along the beach, it transports the sediment
Exposed to powerful waves from the North East
Mechanical weathering like freeze thaw and mass movement are very active along the clifs of the North Norfolk coast
Costal Erosion is very active along the east coast
Costal deposition is dominating the west
Geology
Underlain by sedimentary rock chalk
Cromer ridge
It is a glacical deposition that marks the furthest extent of the ice advance
100 meter high ridge, just inland from cromer
Sands adn gracel deposited by glacical melt water streams are found along the coast in the West of the reagion
The glacial sediments are very weak and they are prone to mass movement and are rappidly eroded by the sea
They are retreating by about 1 meter per year.
Climate
In the last glacial peroid the ice advanced over the area and deposited large amounts of sediment. These have been rapidly eroded due to the fact they were exposed to geomorphic processes
The weather there now is relitavly dry with warm summers and occational cold winters.
The cold weather will promote freeze thaw, particually if the clay contains deep cracks.
Costal landforms
Overstreand and Happisburgh are dominated by eroding cliffs.
In happisburgh, some people have lost their homes use to the rapid costal retreat.
The west of sherringham is dominated with deposition.
There is a extensive spit at blakeney
There are sand dunes at stiffkey
Impact of human activity and management
Fishing, farming and forestry are some of the activities that the people who live around the coast do
Tourists and artists are a massive part of the acitivity that goes on at the North Norfolk Coast
The undamaged costal habitats are a massive part of the touism, as the visitors like to look at the untouched salt marshes and sand dines
At Holkham, the landowner has planted pine trees to help stabalise the sand dunes, also they have constructed board walks to enable people to acsess the sand dunes without damagine the vegitation or disturbing the wildlife
At Wells-Next-To-The-Sea, groynes have been placed around to protect the beach huts, Gabions have been used to help protect the lookout stations from storms. But these can have bed effects down the coast, for example like the beach being starved of sediment
Sea walls have been used in Cromer, Sherringham and Overstrand to protect the coast line
