Question
5- An abrupt rise of 0.8 m was designed to control a hydraulic jump generated after a 4 m wide
sluice gate with an opening of 0.2 m by a flow discharge of 12 m³/s. The flow depth over the
rise is 1.2 m
a) Discuss about the stability of the jump using the attached plot
b) Find the flow depth over the rise to form a stable jump at x=5(h+y3) if the abrupt rise
changes to 0.6 m
