2 of 22
What was the purpose of the fieldwork?
To test various aspects of the bradshaw model
3 of 22
Which factor from the Bradshaw model explains why the HR should increase as you go downstream?
Channel width (and depth) increases as you go downstream
4 of 22
What is the Aim of the fieldwork?
To test downstream changes of Glenderaterra Beck
5 of 22
what should be included in a sketch of the river?

6 of 22
What 3 factors should be looked at when doing a risk assessment?
Risk, Prevention and Ongoing Assessment
7 of 22
What method should be described?
Collecting wetted perimeter
8 of 22
What equipment was used in the method?

9 of 22
To identify the wetted perimeter
10 of 22
What is the formula for Identifying the Hydraulic Radius/HR?
HR = Cross Sectional Area/Wetted Perimeter
11 of 22
What secondary data was sought out during the fieldwork?
Previous fieldwork data; to plot scattergraphs to show impact of river over time
12 of 22
What was the conclusion of the results?
Efficiency does increase as you go downstream
13 of 22
How was the data (Cross Sectional Area) presented?
Scatter graph
14 of 22
What is the spearmans rank coefficient?
Numerical representation showing the extent of which two factors correlate

0.5524
16 of 22
What does critical value mean?
Set of values that show the reliability of the data
17 of 22
What was the critical value for 90% confidence?
0.4554
18 of 22
What conclusion can be drawn if the 90% confidence level is not greater than the spearmans rank value?
A null hypothesis must be accepted
19 of 22
What improvements can be done to the fieldwork for future students?
All of the following
20 of 22
What work can be done in the future to further aid the findings?
Identifying the impact of human development on the HR and other aspects of the Bradshaw model i.e. discharge increasing as you go downstream
