A hydraulic jump takes place in a rectangular channel downstream of a spillway. The flow in the channel is Q = 900 cfs. The conjugate depth (y1) upstream of the jump was measured at 1.4 feet. The channel width is B = 15 feet. (a) Compute the conjugate depth y2 downstream of the hydraulic jump. (b) What type of jump are we looking at in this problem? Refer to the five types presented (in the figure above) by Prof. Ven Te Chow, the father of watershed hydraulics and physical hydrology. (c) Evaluate the specific energies E1 and E2 at points 1 and 2 (upstream and downstream of the jump, respectively) and the specific energy Ec corresponding to the critical depth yc. Then annotate the specific energy diagram below with the values of y1, y2, yc, E1, E2, and Ec. (d) How much is the head loss in the hydraulic jump? Explain your answer

(a) Compute the conjugate depth y2 downstream of the hydraulic jump.
(b) What type of jump are we looking at in this problem? Refer to the five types presented (in the figure
above) by Prof. Ven Te Chow, the father of watershed hydraulics and physical hydrology.
(c) Evaluate the specific energies E1 and E2 at points 1 and 2 (upstream and downstream of the jump,
respectively) and the specific energy Ec corresponding to the critical depth yc. Then annotate the
specific energy diagram below with the values of y1, y2, yc, E1, E2, and Ec.
(d) How much is the head loss in the hydraulic jump? Explain your answer.
