Geography P3 Physical Fieldwork

Question 1

Physical fieldwork investigation question

Answer 1

How effectively is the Holderness Coast protected against erosion?

Question 2

Physical Fieldwork location(s)

Answer 2

Holderness Coast
-Withernsea
-Mappleton

Question 3

Why was the Holderness chosen as a site?

Answer 3

-A variety of management techniques being used and processes to investigate at different beaches
-In driving distance of the school for a day visit
-‘Fastest eroding coastline in Europe’

Question 4

Methods (physical fieldwork)

Answer 4

-Groyne height
-Beach profile
-Wave count
-Longshore drift
-Bi-polar survey of sea defences
-Flood risk mapping

Question 5

Equipment for the Beach Profile

Answer 5

-Ranging Poles
-Clinometer
-Tape measure

Question 6

Physical fieldwork things to consider

Answer 6

Human error
Representative
Enough samples
Opinion based
Calculated mean
How e.g. a wide steep, beach means sediment is deposited rather than eroded and has produced a bigger beach so defences are working
Did it meet the aim
Did measurements allow conclusions to be made about effectiveness
Measurement errors
Subjective & reliable

Question 7

Groyne height

Answer 7

Withernsea- North is 45cm higher than South side

Mappleton- Approximate (difficult to measure) 1.5m higher

Question 8

Beach profile

Answer 8

Depth of beach:

Withernsea- 45m, 3° (deposition occurring)

Mappleton- 27m, 12°

Question 9

Wave count

Answer 9

Destructive waves:

Withernsea- 22 waves p/m

Mappleton- 17 waves p/m

Question 10

Bi-polar of sea defences /5

Answer 10

Withernsea- 4.2 group average

Mappleton- 1.8 group average

Question 11

Flood risk mapping

Answer 11

Risk calculated as 5x5 (max risk)

Zones 1,2,3 at sea front:

Withernsea- 6 risk
Mappleton- 12 risk
