Local scour downstream of radial gates in Non-erodible beds by using a physical model, corrugated beds are employed downstream of hydraulic structures to dissipate the energy and to control the downstream scouring. Several experiments were performed in which beds were considered at four different aprons with corrugation heights of 22, 29, and 41 mm in open channels with zero slope. This paper experimentally explored the effect of the height of corrugation elements on the scour geometry downstream of submerged hydraulic jumps. A case of smooth apron was included to estimate the influence of corrugation types on the scour hole dimensions. Obtained results were analyzed and graphically presented and the scour profiles were drawn in dimensionless forms. The results indicated that as the scour hole increases as the submergence ratio increases, the corrugated beds reduce the scour hole by rate from 27% to 50% in comparing with the scour hole of smooth bed.
