Q1. Gradually varied flow of water in a wide rectangular channelwith 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, theflow depth is
measured to be 0.80 m. (a) Determine the normal and critical depthsof 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 range0≤x≤1000
m. Repeat part (b) to obtain the flow depths for different xvalues, and plot
surface profile
Q2.
A triangular gutter whose sides include an angle of 60°, conveyswater 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 equationwith C=52 m
^1/2/sec
