Determine the normal depth and critical depth in a


Determine the normal depth and critical depth in a trapezoidal channel with a bottom width of 12.5 m, side slopes of 2:1, and a bed slope of 0.003 m/m. The Manning’s n value is 0.022 and the discharge is 75 m3/s. Is the slope steep or mild? Repeat for n=0.012. Did the critical depth change? Why or why not?
