A rectangular channel 3 m width is conveying a water depth y1 = 1.55 m and velocity V1 = 1.83 m/s. The flow enters a transition region as shown in the Figure 1. In which the bottom elevation is raised by h = 0.20 m. Determine the depth and velocity in the transition, and the value of h for choking to occur.
