Abstract

This work shows an application of a two-phase SPH model for the details of the interaction between wave propagation and coastal structures. The numerical solution is based on SPH approximation of the mixture model of the Herschel-Bulkley-Papanastasiou viscoplastic model for calculating a variable yield stress. We have investigated the dynamics and characteristics of beach profile transport related to the wave breaking process. Further, the numerical model results were validated against the experimental and numerical data found in the literatures and some relatively good agreements were observed. Afterwards, variable characteristics of the waves propagated over different sloped beaches are carried out. The results of this study show that the method provides a useful tool to investigate the wave propagation in term of coastal applications and scour around structures in civil and environmental engineering flows.
