A trapezoidal channel has size slopes of 3:1 (H:V), a bottomwidth of 22 feet, a longitudinal slope of 0.0003, a Manning’sroughness coefficient of 0.023, and carries a flow rate of 340cfs.
a) Calculate the normal depth in this channel.
b) Calculate the normal specific energy.
c) Calculate the Froude number. State the classification offlow.
d) State how the critical depth will compare to the normal depthand why.
