    Abstract

    A series of 3-D smoothed particle hydrodynamics (SPH) models with a domain in the form of a water tank were undertaken to simulate tsunami-induced bore impact on a discrete onshore structure on a dry bed. The tsunami-like waves were represented by solitary waves with different characteristics generated by the numerical paddle wavemaker. Numerical probes were uniformly distributed on the structure’s vertical surface with spacing twice that of the diameter of particle, providing detailed measures of the pressure distribution across the structure.This allows the impact forces acting on certain areas to be derived directly from the pressures output. The peak impact location on the structure’s surface can be specifically determined and the associated peak forces are compared with two existing design code predictions. The results show that the equations used to estimate the forces for design purposes can both over and under-predict the forces.
