A horizontal rectangular stilling basin (USBR type III) is used at the outlet of a spillway to dissipate energy. The spillway discharges 350 ft3/scc and has a uniform width of 35 ft. At the point where the water enters the basin, the velocity is 30 ft/sec. Compute the following:
(a) The sequent depth of the hydraulic jump,
(b) The length of the jump,
(c) The energy loss in the jump, and
(d) The efficiency of the jump defined as the ratio of specific energy after the hydraulic jump to the specific energy before the jump.
