A clean-earth channel, for which n=0.020, is 6m wide and lies on a slope of 0.005236. Water flows at 30m3/s through the channel and enters a reservoir. The water depth in the channel, just before the entry to reservoir, is 3m.
a) Determine the uniform depth in the channel.
b) Determine the critical depth in the channel.
c) Sketch the backwater curves for the channel.
d) Calculate the distance upstream from the point of entry to the reservoir at which the water depth is 2m?
