Overstrand’s cliffs are made from deposits of glacial till from the last ice age. The cliffs of Overstrand are made from soft rocks. This makes them prone to slumping caused by sub-aerial process for example weathering and saturation of the rocks. This leads to major slumping such as the slumping at Clifton Way were 40 metres was lost in 1990. Bacton’s geology is comprised of clay, silts and sand. It has a wide sandy beach. It is at risk from coastal erosion such as longshore drift and if it was not protected, the gas terminal would cease to function which would make a lot of the population in Bacton redundant. Also, it poses an environmental hazard if an explosion occurred and gas escaped. Happisburgh is composed of several glacial tills…show more content…
Floods and storm surges pose a threat to this seaside town. Like the 1953 floods which killed 7 people. Because of the floods, several breakwaters were installed. This has lead up to the wide sandy beach which has retained its Blue Flag award. If there is a flood risk, then the flood gates can be closed. The protection of the North Norfolk coast is allocated via a cost-benefit analysis. This is when the cost of the sea defences is compared to the economic value of the area being protected. If the cost is not justified, then the area does not receive any new defences. If the cost of installing new defences is met by the benefit of the area, then a SMP (Shoreline Management Plan) is developed. An SMP (Shoreline Management Plan) is a large-scale assessment of the risks associated with coastal processes and helps reduce the risks to people, agriculture and infrastructure. The organisation responsible for the SMP in north Norfolk is the Environment Agency. The SMP for North Norfolk has been split into two sub cells to make managing easier: Sub cell 3A and Sub cell 3B. Overstrand, Sea Palling, Happisburgh and Bacton are located in Sub cell
