Fieldwork Physical AS (coasts)

Question 1

What was the coastal enquiry question

Answer 1

To what extent is geology a factor in shaping the change/ formation of the North Antrim Coast?

Question 2

Hypothesis & sub-hypothesis

Answer 2

Geology is the most important factor
- Sphericity will be highest with low resistant rock
- Formations will be more diverse —> high resistant
- **Kemphs phrase ** —> Same across coast
- Cliff degradation —> high with landward dip

Question 3

How did we measure roundness of pebbles

Answer 3

Krumbein’s index
- measured and calculated different pebbles roundness —> indicates erosion

Pros:- quantitative
- accurate
- compares. How rock type influences level of erosion/ roundness

Cons:
- Time
- calculations

Question 4

How did we measure the levels of geodiversity and factors

Answer 4

Geo diversity score: Scored sea-level, sediment and land-use

Pros:
- Allowee us to understand how geology impacts what can be done on land
- How other factors impact geology in different areas

Cons:
- subjective
- Hard to identify all sediment

Question 5

How was cliff degredation measured?

Answer 5

Cliff degradation& vegetation scores: Scored this on levels of stability at locations

Pros:
- Comparable
- Easy to do

Cons:
- Subjective
- Assuming vegetations always helps
- secondary data on cliff dip needed

Question 6

Kemps phase definition

Answer 6

• difference between swash time and backwash time

Question 7

How did we calculate how marine processes can impact the coast?

Answer 7

Kemps phase test: counted how many waves broke on the shore and timed swash & backwash times. Averaged out.

Pros:
- comparable with data over time
- more definitive answer in destructivity of waves

Cons:
- Time
- equation needed

Question 8

How did we evaluate intervention/management

Answer 8

Bi-polar management: rated different criteria on management and coastal defences.

Pros:
- Allows us to understand perception
- comparable
- wide range of criteria

Cons:
- subjective

Question 9

Flood risk method

Answer 9

Flood-risk survey: uses indicators on severity*likelihood of a flood
- measures: Heigh of defence, defences, vulnerability of services

Pros:
- Quantitative
- accounts for multiple factors

Cons:
- Time
- Hard to assign values to land-use
