Abstract:

Smoothed Particle Hydrodynamics SPH is a novel meshless numerical method that is being developed for the study of nearshore waves and Navy needs. The Lagrangian nature of SPH allows the modeling of wave breaking, splash-up, and the subsequent fluid turbulence, which in large part is comprised on coherent turbulent structures. Including sediment transport allows the methodology to be applied realistically within the surf zone. 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. Coupling the SPH model to a vertically-averaged more computationally efficient model for larger areas would provide a computationally useful model of the full surf zone.
