FINITE ELEMENT SIMULATION OF WAVE-INDUCED INTERNAL FLOW IN RUBBLE MOUND STRUCURES

H. Wibbeler, H. Oumeraci

Abstract


A Finite Element Model for the simulation of the wave-induced flow in a porous structure is presented and applied to three types of structures: homogeneous vertical structure, homogeneous trapezoidal structure and traditional multilayered rubble mound breakwater. The obtained results are related to the motion of the phreatic surface, the pore pressure histories and distributions within the structure as well as to the internal velocity field induced by wave action. The problems to be solved in order to get an improved numerical model are discussed.
