1GB2: Fieldwork - Coasts Flashcards
What type of sampling was used in Start Bay?
Stratified Sampling
What is stratefied sampling?
probability sampling technique that involves dividing a population into smaller subgroups, called strata, and sampling from each
What type of sampling did beach profiles use?
Systematic sampling
What is systematic sampling?
a probability sampling method that involves choosing a smaller group from a larger population in a regular pattern
What is random sampling?
a statistical method that involves selecting a smaller, unbiased group of participants from a larger population
What type of location was Hallsands?
Small medium houses
Lots of holiday accomodation
A beach protected by rock armour
Car park
What type of location is beesands?
Bigger settlement with facilities
Pub, b and bs, holiday lets, cafes
Protected by sea wall and rock armour
What type of location is Sunnydale?
Beach with remains of a road
Leading to 5 small houses
Gabion baskets in front of houses
What are gabion baskets?
a basket or cage of rocks that is sometimes placed along shorelines to fight coastal erosion.
What type of location is Torcross?
Largest settlement along start bay
Hotels and valuable houses on see front
Holiday lets
Tourist facilities
Pubs and cafe protected by sea wall
What method will you use to figure where the most effective coastal management schemes will be located?
Bipolar survey of management methods
Cost benefit analysis of defences
How do you present a bipolar survey?
Radar graph showing bipolar scores
What method will you use to figure where the most risk of flooding and highest erosion will be?
Flood risk survey
What method will you use to figure where the sea defences will have a positive/negative environmental and social impact?
Beach profiles
Lithology survey
How do you present a beach profile?
Line graph showing beach profiles
How was secondary data used in cost beenfit analysis?
Zoopla used to estimate, large, medium and small houses prices
What was the bipolar survey?
Students scored each coastal defence between -3 and +3 defence against a range of criteria
Higher score - better coastal defences
What is a radar diagram?
Present results of bipolar survey
Results were overlaid over one another
Easy comparison
Larger shape - better coastal management method
What was the cost benefit analysis?
Counted properties of different sizes by counting number of windows
Calculated value of properties - zoopla
Cost per 100 years of defence calculated
Higher score, more cost effective
What was a flood risk survey?
Calculate likelihood of flood and floos severity
Tape measure to measure from sea to buildings
Estimate how high buildings were above sea levels
What was the beach profile?
Big beach = more protection
Clinometer using and tape mwasure
No rangin poles - used eye to eye
What were the results of the beach profiles presented as?
Line graph
