NORTH NORFOLK COASTAL EROSION AND MANAGEMENT
HYPOTHESIS ONE- Coastal management is essential to sustain the economy of Cromer. I think this will be proven by my investigation as without coastal management there would be disruption to businesses.
HYPOTHESIS TWO - Coastal processes pose a greater threat to people in Happisburgh than they do to Cromer. I think this will be proven as the current local government philosophy is to hold the line in Cromer but not defend Happisburgh.
This enquiry will aim to investigate the range of coastal management solutions applicable to the North Norfolk coastal area of Cromer, Overstrand and Happisburgh in order to consider and decide if the above two hypotheses are correct.
Cromer is a town on the north east coast of the county of Norfolk in the east of England. It is around 106 miles north east of Sharnbrook on the North Sea coastline.
Overstrand is a village around 2 miles to the south east of Cromer town centre. The housing in the village extends up to the cliff edge at the North Sea coastline.
Happisburgh is a village around 14 miles to the south east of Cromer town centre. The housing in this village also extends up to the cliff edge at the North Sea coastline.
The coast line of North Norfolk has been subjected to coastal erosion for hundreds (possibly thousands) of years and there is a great deal of historical evidence regarding the changing coastline, the methods of coastal defense used by locals and the economic and social effects of this erosion.
In recent years the North Norfolk District Council (NNDC) has invested a great deal of effort, time and money to understand the expected effects of coastal erosion and to consider strategies that could be adopted to reduce erosion and assist property owners directly affected. They have developed a Shoreline Management Plan which includes predictions of how far the erosion will extend over the next 100 years. In some areas the value of businesses and residential property is high and the plan intends to continue with sea defenses to hold the present coast line. Central UK Government have indicated their preference that nature is allowed to take its course in some areas of lower economic value and that future investment in sea defenses is reduced or stopped. The publishing of this plan and government opinion had a devastating effect on local property prices in these areas and as a result NNDC have conducted consultations with local residents and businesses and prepared a Coastal Management Plan covering social effects of different sea defense strategies. As such a lot of data is available about coastal erosion and the physical and social effects that can be researched in order to consider if the above Hypotheses are correct.
North Norfolk at only 106 miles from Sharnbrook Upper School is close enough that day trips can be made to investigate and gather information to research the subject.
In this research I will be investigating different geographical processes and coastal management along the North Norfolk coastline.
The main geographical processes are:
Explanation: The process known as weathering breaks up rocks so that they can be carried away by the process known as erosion. Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the earth. This photo shows cliff erosion at Happisburgh, North Norfolk.
Sub-Aerial Processes (slumping)
Explanation: clay is a soft, impermeable rock which soaks up water to become saturated. When this happens the clay becomes unstable and begins to slump. Clay cliffs have gentle slope angles. The cliffs at Overstrand in North Norfolk suffer from slumping
