weaknesses of presenting depth and width with a cross section of a river channel

Answer 33

limited data available and not very accurate

Question 34

weaknesses of presenting field sketch as a drawing

Answer 34

not very accurate
not very detailed
subjective
you can miss important details

Question 35

better method than field sketch method

Answer 35

annotating pictures of an area

Question 36

what did you find out from your data

Answer 36

river width, depth and velocity all increase as you go downstream

Question 37

why did river depth, width and velocity increase as you go downstream

Answer 37

due to humans changing and altering the river to reduce flood risk

Question 38

what were the strengths of our question/aim/hypothesis

Answer 38

the sub questions make it easier to answer the question

Question 39

what were the weaknesses of our question/aim/hypothesis

Answer 39

question is too broad

Answer 40

we used more than 1 site
valid results

Question 41

what were the weaknesses of our location/sites/methods

Answer 41

only used 2 sites
equipment not reliable enough

Answer 42

we used multiple reliable sources and graphs

Question 43

what were the weaknesses of our data presentation

graphs had limited information

Question 44

What were the strengths of our analysis and conclusions

Answer 44

valid
we answered all of our questions

Question 45

what were the weaknesses of our analysis and conclusions

Answer 45

limited by investigation scale

Question 46

Explain one limitation of the quantitative fieldwork method you used when
investigating river discharge.

Answer 46

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).

Question 47

Explain one way you could have improved measuring width

Answer 47

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).

Question 48

Explain one way the qualitative fieldwork method you used supported your
understanding of river landforms.

Answer 48

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).

Question 49

Explain one way river processes might affect people living in the catchment area
of the river you studied.

Answer 49

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).

Question 50

Explain one advantage of a qualitative fieldwork method you used.

Answer 50

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)

Question 51

Explain one way the secondary data you collected supported your
investigation.

Answer 51

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)

Question 52

Explain one advantage of the type of graph you used to present fieldwork
data.

Answer 52

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).

Question 53

Explain how this question or hypothesis helped your investigation.

Answer 53

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)

Question 54

Describe one fieldwork method that could be used by the students to
measure river width.

Answer 54

Using a measuring tape (1) the students record the measurement by placing it from one side of river channel
bank to the other (1).

Question 55

Explain one reason why the students chose a stratified sampling approach.

Answer 55

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
