Hydraulic radius is calculated using this method:
Hydraulic Radius =
Cross-sectional Area (m2)
Wetted Perimeter (m)
Channel Cross-section diagrams
The cross-sectional area diagrams are linked to the hypotheses the
width of the river channel will increase and the depth of the river
channel will increase with distance downstream.
are the methods used to test each hypothesis:
Hypothesis 1: The width of the river channel will increase with
This is a study of the changes in river processes along the long ..
Also from this graph it is evident that the average depth of the river
increases with distance downstream which supports the second
