Question

Q1. Gradually varied flow of water in a wide rectangular channel with a per unit

width flow rate of 1 m3

/s-m and a Manning coefficient of n = 0.02 is considered.
The slope of the channel is 0.001, and at the location x=0.0, the flow depth is
measured to be 0.80 m. (a) Determine the normal and critical depths of the flow and classify the water surface profile, and (b) calculate the flow depth y at
x=1000 m by integrating the GVF equation numerically over a range 0≤x≤1000
m. Repeat part (b) to obtain the flow depths for different x values, and plot
surface profile

Q2.

A triangular gutter whose sides include an angle of 60°, conveys water at a
uniform depth of 25 cm. If the discharge is 0.04 m^3
/sec, workout the bed gradient of the trough. Use Chezy’s equation with C=52 m
^1/2/sec
