Holderness Coastline Flashcards
Consider the possible impacts of sea level rise on coastal processes and landfroms along the Holderness coast?
Increased erosion.
Increased stormy conditions - causing more erosion.
More erosion means land retreats - causing bays and headlands.
Erosional processes eg abrasion and hydraulic action increase meaning more sediment.
Arguments for protecting Holderness coastline?
Causes problems for farmers, caravan sites and rural coastline settlements.
Arguments against protecting Holdernes coastline?
Artificially protecting the coastline means it can’t adapt to the system, only put in place to protect housing.
Is management along the Holderness coastline sustainable?
No.
Considerable amount of hard engineering causing headlands to be made.
Causing wave refraction around coastline increasing erosion elsewhere.
How is there conflict around the Holderness Coastline?
Other areas of the coastline apart from the areas indicated do not have any coastal management.
Causing problems for arable farmers, caravan sites and rural coastal settlements.
What direction is the longshore drift along the Holderness coastline?
Dominant LSD from north to south.
In regards of sediment cells, where is the Holderness coastline located?
It forms a subcell in sediment cell 2 and essentially comprises 3 distinct coastal units.
Why are beaches classed as stores?
As they hold sediment.
Name the places where ‘Hold the Line’ is apparent.
Bridlington.
Hornsea.
Withernsea.
What protection is in place at Easington?
Sea wall.
Power station.
What coastal management is at spurn head?
Groynes and sea wall.
They were used in the past but now have been abandoned as spit is in wrong position.
What is wrong with boulder clay?
Soft rock so easily eroded by the sea and sub-aerial processes.

Nature reserve.
Name 3 processes at Spurn Head.
Deposition.
River/sea current convergence.
Spit extension.
Name 3 key issues at Spurn Head.
Full erosion of spit neck.
Isolation of spit head.
Dredging humber estuary.
Dominant process at Flambourgh Head?
Erosion.
Dominant process at Bridlington?

Deposition.
LSD.
At Holderness what is the average annual rate of erosion?
2m per year.
What is the main reason for the erosion at Holderness?
Bedrock made up of glacial till - deposited here by glaciers 12,000 years ago.
What was the name of the ice sheet at Holderness 12,000 years ago?
Devensian ice sheet.
Name the 6 places affected along the Holderness?
Flamborough Head. Mappleton. Aldbrough. Withernsea, Kilnsea. Spurn Hea.
