In this paper, an analytical solution for the response of a porous seabed to combined wave and current loadings is presented. Unlike most previous investigations, currents are considered in this study. Based on the newly analytical solution, a detailed parametric study will be carried out to explore the effects of combined wave and current loading and inertial terms on the pore pressure in marine sediments. Numerical examples demonstrate the significant effects of currents and inertial terms on the pore pressures in shallow water. The relative difference of the maximum pore pressures between the present model and the previous model (without currents) can reach 7% of the static water pressure.
