Prehistoric Engineering Along a Meandering River: a Hypothesis



Hydraulic radius is calculated using this method:

Hydraulic Radius =

Cross-sectional Area (m2)

=

0.19

=

0.186m

Wetted Perimeter (m)

1.02


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.

 The graph supports the hypothesis that the width of the river increases with distance downstream.

These

are the methods used to test each hypothesis:

Hypothesis 1: The width of the river channel will increase with
distance downstream.


This is a study of the changes in river processes along the long ..

Hypothesis 1: The width of the river channel will increase with distance downstream.



Also from this graph it is evident that the average depth of the river
increases with distance downstream which supports the second
hypothesis.
