2) Slope - Area Method
A 26m reach of a certain stream AB was selected with cross section shown below.
At point A of the reach, the elevation was found to be +0.100m while at point B
downstream, the elevation was found to be -0.20Om. Determine what is asked for in
the following questions if n = 0.3.
r = 60m
-35m
a) What is the cross-sectional area of the reach?
b) What is the slope of the river at the selected reach?
c) What is the hydraulic radius of the cross-section?
d) What is Kutter's C?
e) What is the mean velocity of water in the reach?
f) What is the discharge rate of water in the reach?
