Calculate the maximum possible height in feet of a smooth upward step in the channel bottom that would not cause a choke. c. Calculate the specific energy the flow would have to attain in order to be able to flow over a smooth upward step of height 12 ft. Find the depth that corresponds to this specific energy using a root-finder. d. Sketch the specific energy diagram and identify and label with your calculated values: i. The initial depth ii. The critical depth and specific energy iii. The flow depth in feet upstream of AND at a smooth upward step of height 12 ft
