Special Issue Information

Dear Colleagues,

With the rapid development in the exploration of marine resources, coastal geohazard and offshore geotechnics have attracted a great deal of attention from coastal geotechnical engineers and has achieved significant progress in recent years. The purpose of this Special Issue is to present recent advances in the field of coastal geohazard and offshore geotechnics. Authors are encouraged to submit theoretical, numerical, experimental, and applied articles addressing this theme. Topics include, but are not limited to, the following research topics:

  • fluid–soil–structure interactions around marine infrastructure;
  • seismic-induced seabed liquefaction;
  • scour around marine structures;
  • effects of tsunamis on seabed soil;
  • marine geology;
  • soil characteristics and constitutive model for marine sediments;
  • Sediment re-suspension and transport in coastal estuarine
  • centrifugal modelling for geohazard and offshore geotechnics;
  • geohazard prediction and protection;
  • challenges and novel methods in offshore foundation design.;
  • submarine landslide;
  • impact of climate change on geohazard.

An integrated numerical model is developed to study wave and current-induced seabed response and liquefaction in a flat seabed. The velocity-inlet wave-generating method is adopted in the present study and the finite difference method is employed to solve the Reynolds-averaged Navier-Stokes equations with k-ε turbulence closure. The model validation demonstrates the capacity of the present model. The parametrical study reveals that the increase of current velocity tends to elongate the wave trough and alleviate the corresponding suction force on the seabed, leading to a decrease in liquefaction depth, while the width of the liquefaction area is enlarged simultaneously. This goes against previous studies, which ignored fluid viscosity, turbulence and bed friction. Full article

The interaction between wave and offshore deposits is of great importance for the foundation design of marine installations. However, most previous investigations have been limited to connecting separated wave and seabed sub-models with an individual interface program that transfers loads from the wave model to the seabed model. This research presents a two-dimensional coupled approach to study both wave and seabed processes simultaneously in the same FEM (finite element method) program (COMSOL Multiphysics). In the present model, the progressive wave is generated using a momentum source maker combined with a steady current, while the seabed response is applied with the poro-elastoplastic theory. The information between the flow domain and soil deposits is strongly shared, leading to a comprehensive investigation of wave-seabed interaction. Several cases have been simulated to test the wave generation capability and to validate the soil model. The numerical results present fairly good predictions of wave generation and pore pressure within the seabed, indicating that the present coupled model is a sufficient numerical tool for estimation of wave-induced pore pressure.
