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

Physical Model of wave-induced seabed response around trenched pipeline in sandy seabed [PDF]
Applied Ocean Research, 2018 Abstract The phenomenon of wave-seabed-pipeline interactions is one of the primary concerns of coastal engineers and researchers, as it could greatly affect the seabed instability and pipeline safety. Numerous researchers have expended great effort in studying wave-seabed-pipeline interactions in the past.
