What is the hypothesis of physical fieldork?
Hard engineering controls longshore drift in Hornsea
What are the two data collection methods for physical fieldwork?
- Measure the drop either side of the groyne
- Measure the beach length either side of the groyne
How did we measure the drop either side of the groyne?
To find out which direction longshore drift was travelling in and whether the groynes were effectivley trapping sediment on one side to reduce the impact of longshore drift. We chose points along the groynes where there was the biggest difference in the height of the sand. This is a biased sample
How did we measure the beach length either side of the groyne?
We measured the length of the beach from the start of the groyne to swash zone to see whether the groynes were effective in building up the beach.
What type of sampling is it called when we measured the drop either side of the groyne?
stratisfied sampling
What type of sampling is used to measure the beach length either side of the groyne?
stratisfied sampling
Are the physical data collection methods quantitative or qualitative?
quantitative
Why did we choose Hornsea for the physical fieldwork?
- Close proximity to school so the data could be collected in one day
- Hornsea has 15 groynes so we were able to test our hypothesis at a number of locations along the stretch of coast which made the results more reliable as we had a large sample size.
What are the two risks and their mitigations for physical fieldwork?
RISK: Falling on/near the groynes
MITIGATION:
Students given the school emergency mobile number,
stayed in groups of a minimum of 3,
wear sensible footwear
RISK: Drowning
MITIGATION:
Stay above the swash zone while collecting data.
Stay in groups of a minimum of 3
What are the data presentation methods for the physical fieldwork?
SEDIMENT DROP : comparative bar chart
GOOD
- easy to construct
- clear to see if there is a pattern/any anomalies as it was colour coded with a key
- showed both sides of the groyne on one graph for easy comparison
BAD
- x axis only shows categories
- accuracy of the data can be skewed depending on the scale used on the y axis
What is the conclusion to the physical fieldwork?
We concluded that the groynes are effective in reducing the impacts of longshore drift as the comparative bar chart shows that the sediment is consistently higher on the north side of the groyne (average of 50cm). This shows that longshore drift comes from the south and the groynes are trapping the sediment, therefore reducing erosion.
What is the evaluation of the physical fieldwork? .
- my results for the drop in sediment size as we tested a number of groynes and calculated an average drop on each side of the groyne
- my sample size was 10 groynes which is a large sample for the stretch of coast we investigated
- other groups in my class also came to the same conclusions suggesting that they are valid and correct.
- The results enabled me to make accurate conculsions on the success of the groynes in Hornsea
- However, I used a biased sample so other points along the same groynes may give the same results as I measured the point with the biggest difference.
- This reduces the reliability and validity of my results.
- My results would have been more reliable if i had measured a number of points either side of each groyne and calculated an average drop size.
- This would show more accuratley how successful the groynes are in reducing longshore drift
What is the tourism fieldwork hypothesis?
Tourism has has a negative environmental impact on Hornsea
What are all of the Data Collection Methods for the human fieldwork (no detail)
- traffic counts
- environmental quailty survey
- questionnaire
- random
Describe the TRAFFIC COunt data collection method from the human fieldwork
Stood at the side of the road and recorded vehicles/ pedestrians passing. CO2 emissions can be calculated to get quantitative data on the environmental impact.
What type of sampling is the traffic count?
stratisfied sampling
Describe the Environmental Quality Survey
A survey to directly compare the environment in two contrasting locations
What type of sampling is used in the EQS
stratisfies sampling
What type of sampling is the questionsaire for the human fieldwork?
random sampling
Describe the Questionaire data collection method from the human fieldwork
The questionaire was done to gain a public opinion on the impact that tourists have on the environment.
Why did we choose Hornsea for the human fieldwork?
- Close proximity to the school so date could be collected in one day
- Hornsea earns about £8 million each year through tourism. There are obvious economic benefits but the environmental impacts are unclear
- There are many visitors all year round so we were able to ask many people to answer the questionaire
What were the risks and their resolves for the human fieldwork?
RISK: Muggin, abduction, violence
RESOLVE:
- students given the school emergency mobile number
- stayed in groups of a minimum of 3
- stay within instructed areas and know where the teachers are located
RISK: Road traffic accident
RESOLVE:
- Use official crossings,
- stay on the football,
- take care when recording data
- stay in groups of a minimum of 3
