paper 3 Flashcards
main physical question
How effective are the costal management strategies at newton beach
main human question
how successful has regeneration been in cardiff bay
reason for choosing newton beach
- fetch of 7000 km- prevailing wind from south west strong waves
- discordant coastline to date different parts and see rate of erosion
- Range of strategies to protect high value land
- range of attractions manmade and natural
risks at newton beach
- slips trip falls- appropriate clothing and footwear
- weather- waterproofs
- tide- keep a distance
quantitative data at newton
- beach profile (systematic)
- angle of elevation- clinometer & ranging poles (systematic)
- sediment size (stratified-random)
Qualitative data at newton
- powers scale of roundness (stratified-random)
- field sketch (stratified)
- Bi-polar survey (stratified)
3 hypothesis at newton beach
- There will be more sediment on the west side of the groynes compared with the east
- Sediment will be larger and more angular on the west side of the beach
- Costal defences will have an impact on costal processes
results and presentation of beach profile
In beach profile line graph we can see:
- west side steeper (greater gradient)
- cross sectional area is greater on the west side (20.48m^2 vs 23.52m^2)
- positive correlation between distance from shore and height
aligns with prevailing winds and longshore drift
results and presentation of pebble size
we found the east side had a much smaller
presented in a dispersion graph where it was clear the east side had a smaller (inter quartile) range and a lower median compared to the west side proving our hypothesis right(wave refraction. We used a dispersion graph and a box and whisker plot (can show range and anomalies in a variety of statistical info)
limitations of a dispersion graph
- need a large data set- can be easily squewed
- requires statistical measures to be understood and calculated
- only one variable can be shown
results and presentation of sediment shape
divided bar graph showed that while the overall roundness was greater on the east side the west side had a greater proportion of well rounded rocks hence slightly disproving our hypothesis (divided bar chart shows a visual presentation of the different proportions found and makes it easier to make a comparison
disadvantages of a divided bar graph
- in this case angularity is quite subjective and the bar graphs have too small a sample size
- impossible to extract info on specific rock
- cant represent more than one point at a time
advantages and disadvantages of field sketches
- they show important features of the land
- may show the impacts of costal process
- quite subjective and can be vague
reasons for choosing cardiff bay
- recently regenerated
- easily accessible as it is capital of Wales
- many buildings to survey land use
- it has increased in size
risks and mitigation at cardiff
- getting lost- keep copy of map and know meet up points & emergency phone number
- slips trips and falls- appropriate footwear
- people- avoid suspicious looking people and stay in groups of at least 4
hypothesis at cardiff
- Environment quality will be higher in cardiff bay than surrounding area
- the environmental quality will have improved between 1987 and 2024
- there will be a variety of land uses for locals and tourists
- locals and tourists will have a largely positive reception of cardiff bay
data collection methods
- plot of transect on GIS and use of choropleth to show EQS results (systematic to see the gradual decrease)
- rephotography (stratified) to show the change at points of interests
- Land use map(systematic to see most common uses) gives the whole picture
- survey (presented later as a pie chart) to see the general opinions
results of EQS
got worse as you moved out (spots lost opacity) as you moved from area supporting hypothesis
issues with an EQS and choropleths
- subjective scores with no basis
- quite general
- colour may be misleading
rephotography results
there has be an increase in activity and an improvement in the aesthetic value of the land since 1987 e.g cardiff becoming centre of governmental affairs
issues with rephotography (only secondary data)
- can easily be manipulated
- don’t always show the exact same points
- image quality may skew opinions
land use survey and results
almost 66% of buildings were used for restaurants showing not much variety in land use and in fact seeming to have a greater focus on tourists than locals
survey results
80% of participants had a generally positive outlook to the regeneration project however as those who disagreed had strong opinions on the fact it favoured the tourists more data is required
rephotography landmarks
governmental building- pierhead building
rest of the quay
new 500 acre fresh water lake
dragon centre has a modern architectural design
EQS scores in in quay vs north most point
in bay area- 51
north- 26
most common sectors in cardiff bay
tertiary sector mainly food service and shops
what costal management strategies can be found at newton beach
- sand dunes
- sea wall
- rock wall/ rock armour
- groynes
