Simulating wave overtopping on a complex coastal structure using SPH

Abstract

This paper investigates the applicability of Smoothed Particle Hydrodynamics (SPH) for regular wave overtopping. The best practices for creating a 3-D wave simulation using SPH are investigated, focusing on the effect of numerical and physical parameters and creating the geometry of the domain. The simulation is compared to experiments conducted on a channel with complex dike geometry with particular interest in the overtopping volume and the free surface position. Close agreement was found for the free surface position and the volume of overtopped water between the experiment and the simulation.
