1
Q
What is a cuspate foreland?
A
- triangular shaped landform
2
Q
How are cuspate forelands formed?
A
- opposing LSD currents converge at boundary of 2 sediment cells (can come in form of double spits)
- sediment deposited at sea by both currents
- accumulates to create triangular shaped area of deposited material
3
Q
Where is deposition greatest on a cuspate foreland?
A
Nose
- wave refraction from headland reduces wave energy
- results in deposition rather than erosion
4
Q
How is the cuspate foreland at Dungeness formed?
A
- SW prevailing wind direction (W to E LSD)
- Swell waves in English Channel (Opposite LSD)
- LSDs balanced due to management on E side
- Sediment cells are present
- Low lying headland created (Dungeness Point)
5
Q
What is present at Dungeness?
A
- Nuclear power station
- uses 100 million liters/yr of water
- Airport
- SSSI (Sites of Special Scientific Interest)
6
Q
How much sediment is moved at Dungeness?
A
30 000m3/yr
- cuspate foreland grows by 6m/yr
8GE01 - Coasts
