An analytical solution for response of a porous seabed to combined wave and current loading

In this paper, an analytical approximation for the evaluation of the pore pressure and effective stresses in marine sediments under combined wave and current loadings is derived. Unlike previous investigations, non-linear interactions between waves and currents are considered in this study. An analytical solution for the wave–current induced oscillatory soil response in marine sediment is presented first. Based on the proposed analytical solution, a parametric study for the liquefaction potential will be carried out. Parametric study results indicate that the influence of current and non-linear waves on the maximum liquefaction depth is significant.

► We proposed the first analytical solution for the wave(current)-induced seabed response.
► Both current and wave non-linearity affects pore pressure and effective stresses significantly.
► The following currents will significantly increases the maximum liquefaction depth.
