River Study

1
How would you investigate the following hypothesis?
Riffle and pool sequence can be identified in St John’s Beck, north of Thilmere, at Bridge End

2
Calculate the wetted perimeter at each of the sample sites on St John’s beck

3
Present the data for gradient of the river at each of the sample sites. What does it show?

3
Choose an appropriate technique to present the data for bed load size at each of the sample sites

4
Use Spearman’s rank correlation coefficient to test the relationship between average bedload size & distance downstream

5
Use proportional symbols & a map to show changes in bedload size at the different sites

6
Calculate mean discharge at each of the sites

7
Select appropriate techniques to compare bankfull cross sections & wetted cross sections, both statistically & graphically.

8
How does velocity change with gradient?
How would you examine this question? Select the appropriate data & present it in a suitable style.

9
Present the data that show bed roughness using both a graphical & cartographic representation

10 Annotate this picture to accompany an investigation of channel shape. Select & present the appropriate data.

11 How & why does channel depth vary? What hypothesis could you test & how would you test the hypothesis? Include annotation on this photograph.

12
Produce a detailed risk assessment (include annotated photograph(s) or diagrams) for a river study on St John’s Beck.

13
Is there a relationship between bed load size & bed load shape? Investigate!

15
Apply Manning’s equation to the study. What do the results give?
Use this website to calculate Manning’s equation

16
Calculate mean velocity for each site & present the data in a SPATIAL form (i.e. NOT a graph!)

17
Calculate & present the Hydraulic Radius for each sample site. What does it show?

18 Compare bankfull & wetted cross sections. How might you use this information?

19
Examine the relationship between discharge & bedload size

20
Use chi-squared to examine the relationship between the shape & size of bedload

21
What problems were experienced during data collection on St.John’s Beck. How could the data collection have been improved?
