(b) Water flows in a channel whose bottom slope is 0.003 and whose cross section is shown in Figure Q5 (b). The dimensions and the Manning coefficients for the surfaces of different subsections are also given on the figure. Determine the flow rate through the channel and the effective Manning coefficient for the channel. m 8 m 2 m Clean natural channel Light brush n? = 0.050 n? = 0.030 3 m S Figure 05 (h)
