Numerical Modelling of Wave Induced Seabed Response

OCEANS 2022 - Chennai, 2022
The excess pore pressure induced by the dynamic wave-induced pressure fluctuations on the seabed is a major factor causing seabed instability. This study critically examines the mechanism of wave-induced soil response, including pore pressure using an ...

Wave-induced seabed response in shallow water

Applied Ocean Research, 2019
Abstract To simulate the wave-induced response of coupled pore fluids and a solid skeleton in shallow water, a set of solutions with different formulations (fully dynamic, partly dynamic, and quasi-static) corresponding to each soil behavior assumption is presented.

Wave-induced response of seabed: Various formulations and their applicability

Applied Ocean Research, 2009
In this study, a set of generalized analytical solutions are developed for the wave-induced response of a saturated porous seabed under plane strain condition. When considering the water waves originating in deep water and travelling towards the shore, their velocities, lengths and heights vary.

Study of wave-induced seabed response around twin pipelines in sandy seabed through laboratory experiments and numerical simulations

Ocean Engineering, 2022
: Wave-seabed-pipelines interaction is of critical importance in the design of submarine pipelines. Previous 11 studies mainly focus on investigating the characteristics of flow fields and hydrodynamics around a single pipeline.

Centrifuge modelling of wave-induced seabed response in clay

Geotechnique, 2022
This paper describes a programme of centrifuge tests on the behaviour of clayey seabed under wave loading using an in-flight wave loading system. Three model seabeds of kaolin clay capturing typical un-consolidated, normally-consolidated and over ...

Evaluating the hydromechanical responses of seabed–pipelines with rotated anisotropic heterogeneous seabed properties

Ocean Engineering, 2021
Abstract Seabed sediments are inherently heterogeneous and present different fabric patterns including rotated anisotropy. This work aims to investigate the effects of rotated anisotropy in seabed properties on the hydromechanical responses of seabed and pipelines.
