Brighton (physical) Flashcards
(16 cards)
Was the enquiry specific?
No, only testing one hard engineering strategy, only looking at a small stretch of the coastline.
Was it measurable?
Easy to measure with simple equipment.
Was it achievable?
Yes. Groynes were split by groups, no complicated equipment or methods needed.
Was it timely?
Yes, could be completed within the day (but not whole coastline).
What primary evidence was used?
Difference in height sediment on either side of groynes.
What secondary evidence was used?
OS maps of Brighton for sampling locations.
What type of sampling did we use to decide the groynes?
Systematic sampling.
What are the benefits of a bipolar chart?
Can show positive and negative, allows comparison, easy to understand trends as visual. Easy to construct.
What are the drawbacks of a bipolar graph?
Can’t easily extract specific values of data, difficult to spot subtle differences.
What data did we collect?
Continuous.
benefits of using photographs
When used in Tandem with historical pictures a clear change can be seen it can also be used to show our date collection techniques
limitations of photographs
they may not be accurate as depth can be distorted
benefits of systematic sampling
it’s easy and quick so more data can be collected. covers the entire area equally
negatives of systemic sampling
not all sites have equal chance of being selected so therefore there is bias
how could we have improved the data collection
we could increase the sample size, take more measurements for example width of the beach (if beach wider more sediment)
Was it relevant
it was directly relevant to theme of coastal management
