Wave-Induced Seabed Response in Non-homogeneous Anisotropic Seabed

Abstract

In a natural seabed, the soil properties is complicated, which normally vary with soil depth, change of temperature, and geographic characteristics. Furthermore, anisotropic soil behavior is commonly observed in marine sediments. However, most previous studies have been limited to the case of isotropic seabed with uniform soil characteristics. This chapter consists of three major components: (i) analytical solutions for a seabed with variable permeability; (ii) analytical solution for a cross-isotropic seabed; and (iii) numerical model for a non-homogeneous seabed with cross-anisotropic soil behavior. With the newly analytical solutions and numerical model, effects of variable permeability and cross-isotropic soil behavior on the wave-induced seabed response were examined.
