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.

An experimental investigation of wave‐induced sediment responses in a natural silty seabed: New insights into seabed stratification

Sedimentology, 2016
AbstractThe widely recognized global phenomenon of wave–seabed interactions and the resulting secondary stratification processes are complex and poorly understood. To better understand the mechanisms by which the differentiation between fine‐grained and coarse‐grained materials occurs and how new sedimentary sequences form, laboratory flume experiments

Response of Cross‐Anisotropic Seabed to Ocean Waves

Journal of Geotechnical Engineering, 1992
Quasi‐static field equations for fully saturated porous elastic media, based on Biot's theory (1972‐1973), established in the writer's previous works (1989‐1990) are used in order to describe the behavior of such materials under wave ocean loading. A brief description of cross anisotropy with a vertical axis of symmetry (orthotropy) is given.

Effect of wave non-linearity on the standing-wave-induced seabed response

International Journal for Numerical and Analytical Methods in Geomechanics, 2000
Summary: A standing wave in front of a seawall may reach a height more than twice of its incident component. When excess pore pressure occurs, it may even induce seabed instability, hence endangering the structure. This issue was studied previously using only linear wave theory.

Updated Free Span Response Near the Seabed

Volume 2: Subsea Technology; Ocean Space Utilization
Abstract Most offshore pipelines, umbilical’s, and cables installed exposed on the seabed may exhibit free spans. These slender circular cylinder structures, when subjected to external flow, may experience vortex-induced vibrations (VIV), potentially leading to significant fatigue damage.

The Limits of Responsibility: Liability for Damage in the Deep Seabed?

2019
This contribution seeks to discuss the limits of state responsibility as they are witnessed in the topic of international liability. The first part addresses the intersection between responsibility and liability using as a reference point the work of the International Law Commission.

Wave-Induced Soil Response in an Isotropic Seabed

2013
In this chapter, a series of analytical solutions for the short-crested wave-induced soil response, including pore pressure, effective stresses and soil displacements, were presented. The porous seabed was treated as infinite thickness, finite thickness and multi-layered medium.
