Computational Fluid Dynamics (CFD) applications to coastal protection
In this presentation, our past efforts of developing in-house 2D and 3D CFD codes for simulation of wave-structure interaction are briefly introduced. A few typical applications of these models to various problems of coastal hydrodynamics and coastal defenses are then discussed. Next, our recent work of extending the early models to simulate flexible vegetation under wave action are detailed. The new model is validated against extensive laboratory and field data. Finally, this model is employed to study the performance of an ecological sea dike system, which is composed of traditional hard structure of seawall and planted mangroves, under super-typhoon condition.
