This question requires a rationale: essentially what equations did you use. If you are uncertain and would like to you can also upload your working as an image. rectangular channel is carrying a supercritical flow with a discharge / unit width of 0.55 m3/s/m. The flow has a specific energy, E= 1.2. It is decided to build step or a drop over a short reach to obtain critical depth over the step / drop. Find (to two decimal places) 1. The critical depth and 2. The required change in bed level (step or drop) to ensure the flow reaches critical depth over the location of interest. (5 marks) Critical depth = 0.31 m Critical depth 0.47 m Critical depth 0.12m OOO OOO Step up 0.73m Drop down 0.89 m Step up 0.89 m
