Question
EXAMPLE 2: A compound channel is shown in Fig 2.7b. It has the following dimensions: m, =
1, n, = 0.03, b, = 10m, d, = 2m. The upper part of the channel has the following dimensions m,
= 1.5, n2 = 0.0225, b2 = 5m, d2 = 1.5m. The channel bottom slope is S, = 0.0003. Determine the
(i) channel discharge (ii) Average velocity at the cross section.
Solution:
nj=0.03
n2=0.0225
n3=0.03
d;=2m
