Extracted text: Q2. The rectangular channel shown in the Figure is horizontal, and it carries q = 10 cfs/ft. The flow depth upstream of the sluice gate is 5 ft. A hydraulic jump occurs on the downstream side of the sluice gate (no head loss for gate). Determine the flow depth at Sections B and D, and the head loss due to the hydraulic jump. 10 cfs/ft 5 ft B D
