Problem4: Water flows in a trapezoidal channel having a bottom width (B) of 6m, bottom slope (S) of 0.0045, and side slopes (m) of 2 (2 horizontal to 1 vertical). If it has to carry a discharge (Q) of 65 m3/s, what should be the uniform depth (y) required to maintain the flow, given the Manning's n=0.025? Solve this problem using MATLAB, given the following discharge equation for a trapezoidal channel: = [(B + m y)y]5/375 Q = n(B + 2y Vm2 + 1)2/3 n
