... been limited to uncoupling model by linking wave models with seabed models through continuity of pressures at the seabed surface. In this study, we proposed a coupled model to link both wave and seabed models and provide a better understanding of the mechanism of the wave-seabed interactions. Based...

... can visually represent the 3D hydrodynamic characteristics of flow around GMSC, which may be effective to improve GMSC techniques in the potential applications in engineering. With respect to the sediment trapping mechanism around the GMSC structure, GMSC can be used in more complex hydrodynamic...

... analyses performed to simulate the continuous loadpenetration response of a smooth pipe section with particular emphasis on the transition from a shallow bearing capacity mechanism to a deep plastic flow mechanism and elucidates on the practical implications of the key findings.
