Seabed Dynamic Responses Induced by Nonlinear Internal Waves: New Insights and Future Directions

Journal of Marine Science and Engineering, 2023
Strong nonlinear internal waves generate a significant pressure force on the seafloor and induce a pore-pressure response penetrated in the seabed and are thus an important driver of sediment resuspension and a potential trigger of seabed failure.

Wave-Induced Dynamic Seabed Response Around a Submerged Breakwater With Dynamic Permeability

, 2023
In this paper, an integrated numerical model with Open-FOAM for the wave-breakwater-seabed interactions problem is presented. Unlike previous studies available in the literature, the present model adopts Biot’s u-p approximation and considers dynamic ...
