24
Q

what are the strengths of a flood risk map

A

reliable and easy to access

25
what are the strengths of a geology map
accurate reliable easy to access easy to understand
26
what are the weaknesses of a flood risk map
limited information lack of real time data
27
what are the weaknesses of a geology map
doesn't include smaller features not up to date
28
how did we present our velocity data
scatter graph
29
how did we present our depth and width data
cross section of river channel l
30
how did we present our field sketch
drawing
31
how did we present our flood risk map
map
32
weaknesses of presenting velocity on a scatter graph
limited data due to restricted time constraints
33
weaknesses of presenting depth and width with a cross section of a river channel
limited data available and not very accurate
34
weaknesses of presenting field sketch as a drawing
not very accurate not very detailed subjective you can miss important details
35
better method than field sketch method
annotating pictures of an area
36
what did you find out from your data
river width, depth and velocity all increase as you go downstream
37
why did river depth, width and velocity increase as you go downstream
due to humans changing and altering the river to reduce flood risk
38
what were the strengths of our question/aim/hypothesis
the sub questions make it easier to answer the question
39
what were the weaknesses of our question/aim/hypothesis
river didn't show changes quickly question is too broad
40
what were the strengths of our location/sites/methods
we used more than 1 site valid results
41
what were the weaknesses of our location/sites/methods
only used 2 sites equipment not reliable enough
42
what were the strengths of our data presentation
we used multiple reliable sources and graphs
43
what were the weaknesses of our data presentation
graphs had limited information
44
What were the strengths of our analysis and conclusions
valid we answered all of our questions
45
what were the weaknesses of our analysis and conclusions
limited by investigation scale
46
Explain one limitation of the quantitative fieldwork method you used when investigating river discharge.
When measuring the width of the river it was not always clear if the measuring tape was tight and not sitting on the surface of the water (1) this could have caused the measurement to be larger than the actual (1) / this resulted in inaccurate results (1).
47
Explain one way you could have improved measuring width
When measuring the width of the river we could have recorded multiple measurements of the river width (1) which would have provided a more precise profile of the channel (1).
48
Explain one way the qualitative fieldwork method you used supported your understanding of river landforms.
The use of annotated photograph(s)/field sketch(s) to record features of a meander (1) evidence of process identified such as undercutting/collapse of river bank/fastest flow of water on the outside bend (1) which helped to provide evidence of erosional processes (1).
49
Explain one way river processes might affect people living in the catchment area of the river you studied.
Commercial/residential properties located close the river channel are vulnerable to flooding (1) which could lead to damages to the properties and possessions (1) leading to potential loss of people’s possessions (1).
50
Explain one advantage of a qualitative fieldwork method you used.
In my river investigation, I drew field sketches showing the changes at each of the three sites (1) which meant that it clearly showed the width of the river getting wider / to analyse later and help draw conclusions (1)
51
Explain one way the secondary data you collected supported your investigation.
I used a (flood risk) map (1) which informed the choice of three survey sites we investigated along river Tillingbourne (1) allowing us to investigate current changes in the river channel (1)
52
Explain one advantage of the type of graph you used to present fieldwork data.
In my river investigation, I drew cross-section river profiles of the river to show changes in the width and depth across three sites (1). This provided clear evidence which allowed patterns to be seen more clearly compared to just using a data table (1).
53
Explain how this question or hypothesis helped your investigation.
My enquiry question supported my understanding of the aims of the investigation and focus on the main aim (1) through exploring the changes in the width and depth of the river as well as other characteristics (1) to decide how the river channel changes in relation to the Bradshaw Model (1)
54
Describe one fieldwork method that could be used by the students to measure river width.
Using a measuring tape (1) the students record the measurement by placing it from one side of river channel bank to the other (1).
55
Explain one reason why the students chose a stratified sampling approach.
ensure similar sites are used along the river for example just below the confluence, other sampling approaches such as random and systematic will miss significant changes in discharge
