What were our two enquiry questions?
How and why are there variations in quality of life for different areas within Bournemouth?
How effective are the coastal management strategies in Swanage Bay?
What was the coastal area we looked at?
Swanage Bay
What were the two study areas for quality of life?
2 areas of Boscombe:
Churchill gardens- closer to town centre (more deprived)
Shelley Park (More affluent)
Why is swanage bay an appropriate study location?
- Has coastal defences
- Small, manageable beach
- Easy to access- large roads, close to transport links
Name 4 risks and hazards in Swanage Bay
- Getting lost from group
- Sea- stay 1-2m from the sea, stay in large groups, avoid large waves and currents
- Weather- May cause larger destructive waves to form in a storm, sunburn / heatstroke
- Traffic- Small narrow roads- heightened risk of being hit, remain on pavement
Describe the distribution of rock types in Swanage Bay
Soft rock in Swanage Bay was subject a significantly greater rate of erosion, consisting of clay and sediment. As the town expanded, coastal defences were required to reduce erosion and prevent damage of property
What were the reasons to use coastal managements?
Protect the economic viability of Swanage
Reduce flood risk to Swanage
Maintain beach use
Manage risk to properties due to erosion and flooding where sustainable
Maintain geological exposures in relation to world heritage sites and SSSI status
Maintain the outstanding landscape and the views and appreciation of the very coastal environment
Reduce reliance on defences
Why does the South side of Swanage Bay only require a sea wall and do minimum to hold the line?
- harder rock less vulnerable to erosion
- Land steel urbanising used for properties needed for economy- tourist facilities needed
- Expensive land
- Waves concentration on other side sheltered from wind and headland
Why does the North side of Swanage Bay not require any active intervention?
- hard chalk agriculture, few properties
- Owned by national trust, maintain geology
- Exposed to larger waves and wind
Why does the centre of Swanage Bay require hold the line with groynes, sea walls and beach recharge?
- soft rock is susceptible to greater rate of erosion
- Urbanised profitable area
- Key areas for travel and growth of economy
- Roads needed to be protected
- The most private property
What equipment and limitations are there for field sketches?
Pencil, paper, clipboard
Limitations: Objects blocking view, no colour, weather conditions may affect drawing
What is the methodology of wave measurements?
- Place apple 2-3m in ocean
- Record direction of movement and distance travelled
- Count number of waves past a certain point and direction of waves
What’s the limitations of wave measurements?
- Seagulls potentially interrupting experiment
- Wind itself could change direction of movement
- Tide
- Subjective of what waves are counted
What is the methodology of groyne profile?
- using a measuring stick measure distance between sand and top of groyne each side of groyne
- Repeat for all groynes and calculate average
- Use measuring tape to calculate width of beach
What is the methodology of beach profile?
- Begin measuring tape as close as possible to ocean
- Measure to the edge of beach
- Using measuring poles place each 2 m apart and calculate gradient using a clinometer
Name four methods of primary data collection we used for beach profiles
- Field sketch
- Wave measurements
- Groyne profile
- Beach profile
What are groyne profiles used for?
The groyne profiles reflect both the direction of longshore drift and efficacy of besch defences. If there is less sand on the north side of groynes but more collected on the south side of groynes, it suggests sediment is pushed north in the process of longshore drift with the direction of waves but stopped moving by groynes. This thus reduces move,ent of sand down the coats, leading to less sediment deprivation in the South of Swanage beach
What is quantitive data?
Quantitative data is information that can be counted or measured and expressed in numerical values, allowing for mathematical and statistical analysis
What is qualitative data?
Qualitative data is non-numerical, descriptive information that focuses on qualities, characteristics, and experiences, rather than quantities
What is stratified sample size?
Stratified sampling is a method of sampling where a population is divided into subgroups or strata based on shared characteristics. Then a random sample is drawn from each strata. Stratified sample size is the population in each subgroup.
What was another method a private property owner used to protect from rotational slumping and erosion?
- large angled concrete wall
- Shallow gradient reducing weight of cliff and reducing risk of collapsing
- Vegetation roots provide stability for cliff
- Metal wire helped to prevent cliff from collapsing
- Piles- 10 m long poles hold and stabilise cliff
- Drainage pipes to remove water preventing saturation, reducing the weight of the cliff and risk of collapsing
What was another data collection method used?
Coastal defence survey:
The bipolar scale of -2 to +2 with -2 being the worst and +2 being the best, assessing the efficacy of different defences and their price, public preference and aesthetics
Name a hazard in the town of Boscombe?
Town- aggravating or disturbing members of the public, being polite, considerate and respectful, particularly in residential areas, aware of surroundings potential criminality
Name one secondary data collection method for Boscombe
