Coastal management at Bridlington Flashcards
(22 cards)
What is the physical hypothesis?
Groynes are effective at stopping longshore drift at Bridlington
What was the location for the coastal management?
Bridlington
How was coastal management at bridlington a physical fieldwork?
collecting data by physically measuring groynes on the beach
Why did we choose Bridlington for the location of the coastal management?
- travel there and back in a day
- away from unstable cliffs (safe)
- large range of sampling points (reliable)
Why are we studying Bridlington coast?
- Holderness coast is the fastest eroding coast in Europe
What are groynes used for?
trapping sediment
If the groynes are working which compass point will be higher?
higher on the north side
What is the direction of longshore drift at Bridlington?
north/south
How do we measure the groynes?
taken at regular intervals along each groyne reduce bias and show effectiveness
What sort of data did we get from measuring the groynes?
quantitive
What are the perks of quantitative data?
- easy to analyse
- easy to record
What method did we use to present to data from the physical fieldwork?
bi-polar bar chart
Why did we use a bi-polar bar chart?
- visual
- simple
- compare two sets of data (N/S)
How useful was the bi-polar chart?
- useful to explain results
- only shows one area/groyne at once
- no location
How many groynes are there at Bridlington?
17
What was the risk assessment?
- stay in groups
- not allowed near the sea
- look at tide times
- suitable footwear and clothing
What did the results show?
some sediment was trapped by the groynes but many didn’t
Could we prove that hard engineering was effective against lsd?
no
What state were the groynes in?
disrepair, no evidence of being repaired since built over 30years ago
Why were we unable to sample all the groynes?
- high tide
- time constraints
- less reliable and more bias?
What would be more accurate than the rulers we used (blew in the wind)?
- meter rulers
How could we improve the physical study?
- different time of day/year
- sample a larger location
- measure more groynes and points
- use located graphs
