CIV E 632 - COMPUTATIONAL HYDRAULICS AND HYDROLOGY FALL 2021 HOMEWORK No. 6 Design a trapezoidal channel to convey a discharge Q100 = 100 m3/s, given bottom slope S = 0.05, and Manning's n = 0.015. Consider the following set of possible bottom widths b (m): (a) 5; (b) 4; (c) 3; (d) 2; and (e) 1. Consider the following set of possible side slopes z: (a) 1 H : 1 V; (b) 0.5 H : 1 V; and (c) 0.25 H : 1 V. Determine the channel depth y (m) corresponding to the suitable combination of bottom width b and side slope z for which the Vedernikov number drops to a value below 1. What is this value of the Vedernikov number? What is the corresponding value of the rating exponent β for this design condition?
