Abstract Scouring experiments were conducted using a three-dimensional laser scanning technology for angles of the jet spanning the interval from 0° to 30°, and the characteristics of the scour hole in equilibrium conditions were investigated accordingly. The results indicate that the optimal scouring effects occur when the jet angle is in the ranges between 15° and 20°. Moreover, the dimensionless profiles of the scour hole exhibit a high degree of similarity at different jet angles. Numerical simulations conducted using the Flow-3D software to investigate the bed shear stress along the jet impingement surface have shown that More >
