An integrated model is developed to study the response of a porous seabed to combined wave-current loading. While the Reynolds-Averaged Navier-Stokes (RANS) equations with k-ε turbulence closure scheme and internal wave-maker function are solved for the wave-current interactions, Biot’s poro-elastic “u-p” model is adopted for the seabed response. After validated by the laboratory measurement, this model is applied to investigate the effects of wave, current and soil parameters on the wave-current induced seabed response. Numerical examples conclude that interacting with the following currents, waves with a shorter period or greater height lead to smaller values of maximum pore pressure.
