CIV E 632 - COMPUTATIONAL HYDRAULICS AND HYDROLOGY FALL 2019 HOMEWORK No. 6 Design a trapezoidal channel to convey a discharge Q25 = 55 m3/s with an exponent of the rating β = 1.4. Assume side slopes z = 1, bottom slope S = 0.06, Manning's n = 0.03. Assume bottom width b = 1.1 m. What is the flow depth y? Is this channel stable?
