What coastline does the Flamborough head cell include?
Holderness coast, fastest eroding coastline in Europe. Annual rate of erosion is around 2m per year.
Why is the Holderness coast (flam head cell) so fast eroding?
Made of soft boulderclay, deposited by glaciers 12,000 years ago
. The chalk of Flamborough head provides a resistant headland, which contains the sediment cell.
How is the sediment cell being disrupted and what impact will this have on sources, transfers and sinks in different parts of the sediment cell?
1991, £2 million spent on 2 rock groynes + rock revetment to protect Mappleton,
material being carried to the south is not being replaced, caused erosion to increase greatly on the cliffs due to no beach to protect it.
How high are some emergent raised beaches in the isle of Arran?
North of Drumadoon on the Isle of Arran, a raised beach is now 5m above the current sea level.
There are 7 raised beaches and fossil cliffs in Scotland.
What is the rate of isostatic rebound in the east of Scotland? (basically like how much the land goes up each year)
Current rates of isostatic rebound in the east of Scotland are between 1.8 and 2mm per year.
