Extracted text: Water in a rectangular, finished-concrete channel, n = 0.017 overflows a dam, as shown in the figure below, and goes into a stilling basin at which there is a hydraulic jump. If the channel is of width 15.5m, has a slope 0.00367, and carries 26.75 cumec, calculate the depth y at O and the depth y2 at the hydraulic jump. Figure 2: Junmp 8m 0.00367 163 m
