The Submerged Hydraulic Jump Downstream Sluice Weir

摘要

The hydraulic characteristics of submerged jump in the stilling basin with a horizontal bottom in the downstream of a camel-back-type sluice weir has been researched based on experimental model. It can be considered that when the Froude number F_r1 before submerged jump is from 3.4 to 7.3 and the submergence coefficient is less than 0.7, the flow condition in stilling basin and its downstream area will not worsen even the free jump becomes submerged. The energy dissipation effect of the submerged hydraulic jump is better than that of the free hydraulic jump.
