A method to predict numerically scouring processes is discussed. The method is based on an SPH description of the flow, coupled with a conventional description of the bed evolution based on the Exner equation. The method is tested against measurements of bed evolution and water velocity obtained in the case of the local scour downstream of a protection apron caused by a planar jet flowing from a sluice gate. The results show that the predicted evolution of position and depth of the maximum scour agree quite well with the experimental data.

Abstract

A method to predict numerically scouring processes is discussed. The method is based on an SPH description of the flow, coupled with a conventional description of the bed evolution based on the Exner equation. The method is tested against measurements of bed evolution and water velocity obtained in the case of the local scour downstream of a protection apron caused by a planar jet flowing from a sluice gate. The results show that the predicted evolution of position and depth of the maximum scour agree quite well with the experimental data.
