Q
What pattern does cross sectional area exhibit?
A
Positive correlation, little plateauing, rising from 0.128m2 @ 1000m from source, to 0.201m2 @ 3000m FS
rate of increase raises incrementally from each point
1
Q
River discharge
What are the values of river discharge from 1000m FS to 3000m FS
A
1000m @0.09 cumecs
3000m @ 0.1 cumecs
Plateau - 1500-2500m @ 0.076 cumecs due to rejuvenation where energy is expended in plunge pools to reverse isostatic change
2
Q
How does bed load size alter across the length of the river
A
Zero correlation
At 1000m FS - very angular, 5x8x3
Similar at 3000m. Due to sediment entry due to scree and rock outcrops entering due to floods
