Data Gathering Flashcards
Physical gathering methods:
Beach profile, microclimate analysis, pebble/sediment analysis, slope analysis, soil analysis, stream analysis and vegetation analysis
Human gathering methods:
EQS, interviews, pedestrian and traffic surveys, questionnaires and land use mapping
Three types of sampling:
+ random
+ systematic (regular intervals)
+ stratified (specific characteristics)
How do you carry out a beach profile?
Ranging poles placed at each peak and trough, measuring tape stretched between them, clinometer held at red line
Consideration of a beach profile:
+ tides
+ weather (wind or rain)
+ ranging poles must be held straight and placed in the sand at a constant depth
How do you carry out a microclimate analysis?
You must record: \+ temperature (thermometer) \+ wind speed (anemometer) \+ humidity (hygrometer) \+ soil moisture (moisture meter) Etc...
Considerations of a microclimate analysis:
+ the effects of vegetation
+ buildings
+ seasonal changes
How would you process the data found in a microclimate analysis?
Polar graph for wind
Line graph for temperature
Bar graph for rain
How do you carry out a pebble/sediment analysis?
Place quadrant, collect sediment, measure with calliper and use power scale index to classify
How do you process sediment analysis data?
+ power scale index as divided bar graph
+ Zing classification
How do you carry out a slope analysis?
Same as a beach profile
Considerations of slope analysis:
+ stratified sampling used to record significant gradient changes
How do you carry out a stream analysis?
Measure the width of the river, measure the river depth, calculate velocity with floating item and collect sediment with water bottle
Considerations of a stream analysis:
+ safety near water
+ rainfall events and patterns
How would you process data gathered from a stream analysis?
+ cross section
+ line graph for velocity
+ line graph for deposition
