3-D EDDY STRUCTURE AROUND THE BREAKWATER HEAD WITH WAVE OVERTOPPING

Wave fields around a breakwater head with wave overtopping were investigated by using large eddy simulation. The complex forms of vortices and Lagrangian vortical fluid motion involved in the vortices were discussed. The three-dimensional eddy structure around a breakwater head is composed of many vortex tubes intertwined and interacting with each other. A complex eddy structure around the breakwater head might cause local scour and promotion of sediment suspension.
