Q =10, 15 m3/s and the slope will be S = 15 cm/km and the side
slope, so Z =1. For a trapezoidal channel, given the flow rate, Q,
the slope, S, the side slope, Z, n = 0.014, the channel is to be
designed to have minimum cost. You are required to: a) What is the
value of Q and S? b) What is the ratio of bottom width, b, to flow
depth, y? c) Design and draw the...
