An integrated three-dimensional model for wave-induced seabed response in a porous seabed. I. A sloping seabed [PDF]
Ocean Engineering, 2005 In this paper, an integrated model for the wave-induced seabed response in a porous seabed is proposed. Most previous studies have considered two-dimensional cases and a flat seabed. In this study, a full three-dimensional case is considered as well as a sloping seabed. The wave model (SWAN) and soil model (PORO-WSI) is coupled into one model. With the
