An upstream channel enters a horizontal channel at a discharge of 792 cfs. The upstream channel has a slope of 0.04 and a Manning's n of 0.03. Both the upstream
channel and the horizontal channel are 10 feet wide in rectangular shape. a is assumed to be 1. (a) Determine if a hydraulic jump will occur, and (b) if the hydraulic jump
occurs at the junction of the two channels, compute the conjugate depths of the jump and the head loss from the jump. Assuming the normal depth for upstream
channel is depth before the jump.
