Starting Point Flashcards
0
Q
What hypotheses were tested?
A
- velocity increases from the source
- hydraulic radius increases from the source
- channel depth and width increases from the source
- bed load decreases in size and becomes more rounded/smooth
1
Q
What were the aims of the investigation?
A
Investigate downstream variations in river channels and make links between changing velocity and discharge, wetted perimeter and hydraulic radius and cross channel depth
2
Q
Why was the area suitable?
A
- Rapid changes found more in upper course (4 hours to do tasks)
- Shallow and free from dangerous under currents
- Land owners permission given
- Little influences from humans
3
Q
How did you respond to risks associated with the chosen sites?
A
A full risk assessment was conducted at the river’s edge.
Potential hazards were identified and given a low, medium or high rating and a control measure was put in place to address the hazard
4
Q
Describe the theory underpinning the investigation
A
To discover if the Bradshaw model can be applied to the River Derwent
Rivers change in characteristics due to changes in discharge, gradient and velocity
