NUMERICAL DETERMINATION OF WAVE INDUCED FLOW IN RUBBLE MOUND BREAKWATER

Z.C. Sun, A.F. Williams, N.W.H. Allsop

Abstract


This paper describes a numerical model of wave action onto and into a rubble mound breakwater. The model is constructed of two parts, the wave action on the exterior of the mound in which a boundary element method is used and flow inside the rubble mound in which a finite element method is used. The two parts of the model are coupled by demanding continuity of flow through the front face of the breakwater. The predicted pressures within the core of the rubble mound are compared with data collected from physical model tests.
