6. Which one of these is not a true aspect of the Bradshaw model?

  • Velocity and discharge increase as you go downstream
  • Gradient decreases as you go downstream
  • Channel width decreases as you go downstream
  • Particle size decreases as you go downstream

7. 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
  • Velocity increases as you go downstream
  • Gradient decreases as you go downstream
  • Volume of load carried increases as you go downstream

8. Which one of the following describes stratified sampling?

  • All data has the same possibility of being chosen
  • Data divided into characteristics of choice i.e. Every blue flower
  • Data with consistent increments i.e. every 10 metres

9. Which one of these characteristics of the 3rd order river is correct?

  • 5km from residential areas
  • truncated spurs
  • In proximity to an old mine; mine debris along the river
  • Close proximity to keswick

10. What secondary data was sought out during the fieldwork?

  • Geographical textbooks; to identify theory behind the results of the fieldwork
  • Webpages; to identify whether any chemicals were present in the river
  • Previous fieldwork data; to plot scattergraphs to show impact of river over time
  • Google maps; to show visual images of sections of the river that we didn't look at

11. What equipment was used in the method?

  • Chain tape measure
  • Spirometer
  • (Plastic) Tape measure
  • Ruler

12. How was the data (Cross Sectional Area) presented?

  • None of the following
  • Table
  • Scatter graph
  • Pie chart

13. What is the spearmans rank coefficient?

  • The constant of river erosion
  • Subjective representation showing the extent of which two factors correlate
  • Numerical representation showing the extent of which two factors correlate
  • Chewing gum

14. What was the Spearmans rank coefficient value for the fieldwork?

  • 0.5520
  • 0.6524
  • 0.5524
  • 0.1997

15. What 3 factors should be looked at when doing a risk assessment?

  • Risk, Prevention and Ongoing Assessment
  • Hazard, Risk and Contingency Plans
  • Hazard, Hazard management and impact on fieldwork
  • None of the above

16. What method should be described?

  • Collecting wetted perimeter
  • Identifying rock characteristics
  • Identifying width changes
  • Identifying water temperature

17. What improvements can be done to the fieldwork for future students?

  • All of the following
  • Identify more stream orders to undergo the testing
  • Use a metal tape measure instead of a plastic tape measure
  • Collect a greater volume of data from the stream orders

18. What does critical value mean?

  • A value used for Health & Safety regulations to determine the safety of the method
  • Set of values that show the reliability of the data
  • Set of values that decide how linked the two factors are
  • None of the above

19. Which one of these characteristics of the 1st order river is incorrect?

  • Permeable slate
  • Impermeable slate
  • Rough grazing; due to sheep raising
  • Thin Soils; allowing quick infiltration

20. Which one of these characteristics of the 2nd order river is incorrect?

  • Collapsing dry stone; impacting ability to measure whole river
  • Deforestation; for human development
  • Aforestation; for environmentally enhancing land
