Dr Yan Zhou (a) A trapezoidal channel, as shown in Figure 4(a), with a bottom width of B = 5m and side slopes of 1 in 0.7 carries a flow of 15m³/s. The channel's slope and Manning's n are 0.008 and 0.015 s/m¹/3 respectively. i) Determine the normal and critical depths. ii) Classify the state of the given flow. [8/25] [2/25] 1 0.7 B-5m Figure 4(a) (b) If the channel in (a) is followed by a steeper channel where the flow is supercritical (Figure 4 (b)), sketch the surface variation. [8/25] FORVEY Steeper than the channel in (a) Figure 4(b) (c) If the flow in the channel (a) ends in a reservoir with depth from the bottom of the channel being 2m as in Figure 4(c), sketch the surface variation.
