key physical and human features of the fieldwork landscape
north yorkshire moores national park / lots of tributaries in the first 200m / large drainage baisin / A169 good access / areas of woodland show effect of interception
1 of 12
describe the method of primary data collection
stratified sampling- 400m apart / at each site put the flow vane in river facing upstream / stood to one side / timed 1 minute / recorded the number of spins / repeated on the left and right side / used the formula to convert to m/s
2 of 12
justify the method of data collection
variable on the BM / 5 sites means you can see the rate of change / same method at each site means its reliable / compare to other variables / took average across the chanel so takes into account meanders / gives a number that can be analysed
3 of 12
evaluate method of data collection and give alternative
shallow water at site 1 meant no record was taken / vegetation at site 2 effected reading / easily broken and bettery issues / only did at 5 sites // alternative = float method
4 of 12
describe the method of data presentation
worked out a scale/ horizontal = 1cm= 20cm / vertical scale = 1cm = 10cm / drew a straight line to show the width / for every 20cm across i drew a dot to show the depth / connect the dots free hand / repeated for 5 sites
5 of 12
justify method of data presentation
compare characteristics that on the the BM / showed the shape / see rate of change / easy to carry out
6 of 12
evaluate method of data presentation and say alternatives
site 1 was narrow so only 1 measurment took / rocks in site 3 skewed the results / doesnt show all variables // alernative = scattergraph
7 of 12
justift the method of data analysis
quantifiable results / shows positive and negative relationship / shows significance / compare to BM / easy to carry out
8 of 12
evaluate the method of data analysis and offer an alternatrive
doesnt say why / doesnt show rate of change downstream / affected by outliers / alternative is scattergraph
9 of 12
conclusions of the invesitgation
velocity increases downstream (like BM) from 0.167-0.304 / discharge increased more than velocity (like BM) / as you go downstram discharge increases but not at a constant rate
10 of 12
porblems with out investigation
only did 1 day / only did 5 sites / only did upper course / only did 1 river / rained half way through the day so people who collected the data second got very different results
11 of 12
secondary data used in investigation
OS maps to plan route / weather forecast / previous school groups data to compare
