Experimental study of hydraulic jump characteristics in trapezoidal channels

الملخص EN

In the presented study, the hydraulic jump in a trapezoidal channel has been studied experimentally.

trapezoidal channel sections of bed width 20 cm, and side slopes (1h: 1.5v) and (1h: 1v) was fixed d/s a control sluice gate.

for each side slope, the discharges ranging from 5 lit/sec to 25 lit/sec were passed in the channel to form hydraulic jump.

the obtained results were analyzed and compared to determine the effect of side slopes and incoming Froude number of the flow on relative energy dissipated in the jump.

empirical equations and curve relations between sequent depths, relative energy lost in the jump and incoming froude numbers were obtained.
