... ABSTRACT Soil permeability is one of key factors in the prediction of the wave- induced seabed response, which will directly affect the design of foundation around marine installations. Most previous studies in the field treated the soil permeability as a constant, although it depends...

... results indicate that the transient pore pressure is dominant in the upper part of the seabed while the residual component prevails in the lower one. Parametric studies are conducted to investigate the effects of the current velocity, the wave steepness, and the soil permeability on the pore pressure...

... the wave-induced pore pressure and stresses in marine sediment. The new boundary value problem was solved by the Legendre pseudo-spectral method numerically. Based on the new model, we investigate the effects of soil permeability, seabed bottom function on the pore pressures and vertical effective normal...

... with time is also studied. The simulation results show that production of natural gas from a hydrate reservoir is very sensitive to several reservoir parameters, such as wellbore pressure and stratum porosity and permeability.
