Abstract

This study complements the wave kinematical investigation on the performance of rubble mound breakwater under uni and multidirectional waves. The measurements of wave kinematics over the head and trunk sections were undertaken to achieve an improved understanding of the influence of wave directionality on the stability of armour layers. The directionality and magnitude of velocity vectors over the head and trunk sections under 3D waves were assessed by comparing them with the measurements under 2D waves. The sensitive zones of the initial damage in the head and trunk were evaluated by linking the velocity measurements with the stability formulas for armour stone movement.
