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 = 15feet. (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 figureabove) 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 thespecific 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 community is installing a new well in a regionally confined aquifer with a trans- missivity of 2675 ft2/day and a storativity of 0.0002. The planned pumping rate is 750 gallons per minute. There are several nearby wells tapping the same aquifer, and the hydrogeologist in charge needs to know if the new well will cause significant interference with these wells.
