Abstract
    In this paper a “semi-dynamic approach for the slope stability analysis of rubble mound breakwaters” is presented. The principles of the method are described. Tide and wave action are taken into account in the slope stability analysis of deep slip-surfaces. For these slip-surfaces the moment of maximum wave run-up is most critical.Pore water pressure variations at the seabottom are also measured below the seabottom but attenuated and approximately up to the so called influence depth hID. The fact that the pore pressure variation is attenuated leads to “overpressures” at the moment of low water and below the wave trough. The attenuation depends mainly on the wave period T and soil characteristics k (permeability) and Eoed (oedometric compression modulus).
