Hypothesis And Results Flashcards
What was the aim of the coastal fieldwork in Start Bay?
To investigate the costs and benefits of contrasting methods of coastal management in Start Bay.
What sampling methods were used during the fieldwork?
Stratified sampling for sites; systematic sampling for beach profiles.
What was Hypothesis 1? What methods were used to test Hypothesis 1?
The most cost-effective coastal management schemes will be located in specific areas.
Bipolar survey, cost-benefit analysis, and radar graph presentations.
What was Hypothesis 2? What methods were used to test Hypothesis 2?
The risk of flooding and erosion is highest in certain locations.
Flood risk survey combining likelihood and severity scores.
What was Hypothesis 3? What methods were used to test Hypothesis 3?
Sea defences have positive/negative environmental and social impacts.
Beach profiles, lithology surveys, and field sketches.
Which location had the highest overall bipolar score?
Torcross
What did the bipolar survey measure?
Effectiveness of coastal defences based on criteria scored between -3 and +3.
Which location scored highest in the cost-benefit analysis?
Sunnydale
How was the cost-effectiveness calculated?
By dividing property values by the 100-year cost of defences.
Which location had the highest flood risk score?
Torcross.
What factors contributed to the flood risk score?
Likelihood of flooding and flood severity.
Which location had the largest beach cross-sectional area?
Hallsands
What does a larger beach cross-sectional area indicate?
Greater protection against flooding and erosion.
What was the dominant beach material identified?
Flint
What did the lithology survey reveal about coastal processes?
It showed that beach material originated from marine transgression.
What qualitative data was collected through the field sketch?
Observations of the impact of sea defences on people and the environment.
How was flood risk assessed?
By calculating scores for flood likelihood and severity.
How were beach profiles analyzed?
Cross-sectional areas were plotted as line graphs to assess beach size and defence effectiveness.
