Smoothed Particle Hydrodynamics SPH is a meshless numerical method that is being developed for the study of nearshore waves and other Navy needs. The Lagrangian nature of SPH allows the modeling of wave breaking, surf zones, ship waves, and wave-structure interaction, where the free surface becomes convoluted or splash occurs. The objectives of this project are to improve the SPH model for use in unraveling the physics of breaking waves, including the description of the wave-induced turbulence and sediment transport within the surf zone. In addition, the interaction of waves with structures is being investigated. APPROACH The approach is based on improving various aspects of the SPH code, including the development of a graphics processing unit GPU version of the code GPU-SPHysics applying the code to more validation tests and to examine in some detail new aspects of the model by applying it to different situations. The development of a hydrid model, that is, coupling the SPH particle model to a conventional finite difference model a Boussinesq model, FUNWAVE has been achieved.
