Question

The discharge in a channel with bottom width 3 m is 12 m3 s–1.
If Manning’s n is 0.013 m-1/3 s and the streamwise slope is 1 in
200, find the normal depth if:

(a) the channel has vertical sides (i.e. rectangular
channel);

(b) the channel is trapezoidal with side slopes 2H:1V.

(Answer with steps plz)

Answer #1

3. A trapezoidal channel has a base width b = 8 ft and side
slopes 6H:1V. The frictional slope is Sf = 0.035 and the Manning
roughness coefficient is n = 0.014. Design a channel if channel
discharge is = 15.45 m3 /s using Mannings
equation. The farmer land is 3.482 acre with a
length of 951.43 ft. what is the best length for the grass
waterway?

7. A) Find the depth of water flowing through a triangular
channel having a bed slope of 1 in 3500 and side slope of 1:1, when
it carries 1.2 m3/s. Take Manning’s Coefficient N = 0.014
B) For a most economical trapezoidal section of side slope 2h: 5V,
bed slope of 1 in 2000 and C = 50. Find the rate of flow if the
bottom width of the channel is 5 m.

A rectangular channel of bottom width B = 7 m carries an average
discharge of Q = 8 m3/s. There are two successive long
reaches. The first reach has s01=0.015 and
n1=0.010; and the second reach has s02=0.0077
and n2=0.021. Classify the slopes.

A. Starting from the specific energy equation [E = y + v2
/(2g)], drive an expression for the critical flow depth (yc) in a
rectangular channel as a function of the flow rate /unit width (q).
Proof also that Froude number in that case =1.0
B. A trapezoidal channel with a bottom width of 4 m and side
slopes 4H: 1V carries a discharge of 30 m3 /s. The channel has bed
slope= 0.1 % and manning roughness coefficient =...

Calculate the depth of flow in a trapezoidal channel
with a bottom width of 3m and whose walls slope 40 degrees with the
horizontal. The channel is made of unfinished concrete and is laid
on a 0.1% slope. The discharge is 15m^3/s.

A hydraulic jump is formed in a trapezoidal channel of 2.0-m bed
width, 1:1 side slope, and carrying a discharge of 6.0 m3/s. The
initial and final depths of the jump are 0.5m and 2.0m,
respectively. Concrete blocks are placed to stabilize the jump. Cf
= 0.6. Construct the M-y diagram for the channel section. Find the
critical depth.

Consider the California aqueduct, which is a concrete
trapezoidal channel with a bottom width of 40 ft, a longitudinal
slope of 0.004% and 1.5H:1V sideslopes (z = 1.5). Assume n =
0.013.

Design a concrete-lined canal to carry a discharge of 10,000
cfs. The canal has a Manning’s n = 0.015 and is to be laid on a
longitudinal slope of 0.0007. If the canal is designed to have a
trapezoidal cross section with a side slope of Z = 1.5 and a bottom
width/normal depth ratio of b/yn = 3.0, determine its required
bottom width, depth, and free board. What is the Froude number
(Fr)? Will the canal have a supercritical...

A trapezoidal channel is 6 m wide and has a side slope of 0.5
horizontal: 1 vertical. If the
bed slope of the channel is 0.0004 and Manning’s n = 0.02,
find the discharge which can
make the channel a hydraulically efficient channel
section.

an water vertical sluis gate freely 56 m3/s into a rectangular
channel 7 m wide . the gate whic is the same width as the channel
is set at a height of 1.4m above the bed and the depth at the vena
contracta is .85 m the energy loss in the converging flow at a
sluis is quite small so take the head loss B as .05v2 / 2g the
normal depth in the downstream hz=2.6m
