    River Study River Study Presentation Transcript

    • 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!
    • 14
    • 15
      • Apply Manning’s equation to the study. What do the results give?
      • Use this website to calculate Manning’s equation
      • http://www.lmnoeng.com/manning.htm
    • 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?
