Field Work Flashcards
What was the enquiry question for the urban area
How does quality of life vary in Guildford
What is the hypothesis in the urban fieldwork
The quality of life will increase as the distance from Guildford town centre increases
What quantitive primary methods were used in the urban fieldwork
Traffic count and litter count
How reliable were traffic count and litter count
A bit reliable but only counted at one point during the day and only covered a small area
What was the procedure for litter count
Count how much litter you see in a certain area for 10 minutes
Describe the traffic count
Quantitive stratified sampling method
Set a timer for 3 minutes and count how many vehicles drove past in a certain direction within the 3 minutes. The data will tell us how much pollution there is
Results recorded for all 3 sites
Pen paper and IPad
Describe the decibel reading
Quantitive random sampling
Stood in a field with my iPad with the decibel reading app and stayed silent when the decibels were being read
Recorded minimum, average, max and what it sounded like eg loud street
The reading tells us how much noise and air pollution there is
Describe the bi-polar environmental survey
Quantitive stratified sampling
Went to a site and gave our opinions on the site eg graffiti and ticked the level we thought it was at
Pen and paper
Gave an overall base on what quality of life was like in our opinion
What are some risks of the urban field work
Getting lost
Hit by a vehicle
Mimi bus crash
Fighting members of public
What was a problem with the traffic count
Only measured traffic at one ready at each site and only vehicles travelling on one side of the road
Problems when doing the decibel reading
It was windy
Problems with the litter count
We only saw a small area within the 10 minutes
What was a problem with the bio polar survey
Was done by us so therefore was bias
What was a problem with the field sketch
Area could look different on other days
What river did I study
River tillingbourne
What sites of the river did I investigate and what are some facts
Abinger hammer, crossways farm, gomshall
50km squared drainage basin
Why were these sites specially chosen for the river field work
Very accessible
Local
It’s safe
What were the primary quantitive data collection methods in the river fieldwork
Width, depth, velocity
What were qualitative primary date collection methods
Field sketch
Problems with measuring the width and solution
Hard to measure as tape measure kept being dragged by current therefore use a chain or something tighter to make the measurement more accurate
Problems with measuring the depth and a solution
Stones could be in the way of the ruler therefore move all rocks from the river channel before measuring
Problems with measuring the velocity and solution
Hydroprop stopped spinning due to debris in the river therefore remove debris in the river
Problems with field sketch and solution
Only went on one day at one time therefore go see the river more than once
Problems with secondary data
Data will be outdated therefore get secondary data from more recently
Describe gomshall site
Concrete road so increased surface run off
Flood wall so prevents flooding to protect roads snd houses
Channelised to decrease risk of flooding
Describe abinger hammer site
2.9 metres wide
Grass and permeable rock
Been channelised to increase the velocity and decrease the flood risk
Crossways farm description
1.5-2 metres wide
Grass and permeable rock so easy to erode
Interception due to small amount of trees so decrease flood risk
Describe width of river procedure
Took 0 end of the tape measure and put it at the water line at one bank and straightened and pulled the tape measure to the other end of the water line and bank
Describe the velocity procedure
Put ruler at bottom of river in line with stream and put my foot on it to keep it straight. Then put cork at start of ruler and measure how long it takes to get to end of ruler
Depth of river procedure
Metre stick and vertically put it up to measure the depth in 5 areas across the width of the river
What is the hypothesis of the river field work
Flood risk increases downstream on the river tillingbourne due to the faster flow and more discharge thid is because when the river flows faster the discharge will increase
