Coastal Processes
Cley and Overstrand
Both Cley and Overstrand are villages located on the low-lying coast of north Norfolk. In the west is Cley that was originally one of the busiest ports in England and Overstrand, in the east, was a thriving fishing village.
INTRODUCTION:
The two villages in North Norfolk of, Clef and Overstrand were chosen because they have completely different landforms, and in both places man have tried to intervene with nature. In the west is Cley, which has been effected by deposition, and Overstrand in the east, were erosion has taken place, causing 700,000m of cliff to erode every year. The area of North Norfolk has low lying coastlines with soft rock which speeds up the erosion processes causing masses of deposition every year.
THE AIMS:
During the enquiry there are three main aims for each place:
· What are the landforms like?
· What evidence is there that they are influence by geology, past and present processes?
· How are the processes being influence by human activity?
BRIEF HISTORY:
CLEY:
Cley-next-the-Sea is a stopping point for migratory birds and a unique home for the bird population. The attractive coastal village with flint cottages, a mediaeval church and a windmill edging on to the marsh are big tourist attractions. In mediaeval times Cley was a major port on the Glaven estuary. Ships of substantial size docked there with cargoes of fish, spices, oriental cloths, coal, timber and oilcake.
In 1570 Cley had many ships and a population of 450. However, the port gradually silted up due to the deposition of the coast, leaving only marshland between the villages, as it is today.
OVERSTRAND:
Overstrand is a village with a population of 950, situated on the north coast of Norfolk in England. It used to be a modest fishing station, known as Beck Hythe. In the latter part of the 19th century it was thrown into prominence, and became known as “the village of millionaires”.
As with much of the Norfolk coast, erosion is a major problem. The soft, clay cliffs which contain water throughout causeing slumping, and the resulting material on the beach is removed by the high tides. And so the process continues over the years.
BACKGROUND INFORMATION:
Overstrand has soft cliffs of glacial and fluvio-glacial material on top of chalk, slumping takes pace because the cliffs are made of permeable sands and gravels overlie the clay so lots of water is allowed to seep into the cliffs causing them to slag and
