Wave-induced seepage flux into anisotropic seabeds

Considerable effort has been devoted to quantifying the wave-induced soil r esponse in a porous seabed in the last few decades. Most previous investiga tions have focused on the analysis of pore pressure and effective stresses within isotropic sediments, despite strong evidence of anisotropic soil beh aviour reported in the literature. Furthermore, the seepage flux, which is important in the context of contaminant transport, has not been examined. I n this paper, we focus on water wave-driven seepage in anisotropic marine s ediments of finite thickness. The numerical results predict that the effect s of hydraulic anisotropy and anisotropic soil behaviour on the wave-driven seepage in marine sediment are significant.
