Abstract
At past, ports have been mainly developed in natural harbors but nowadays ports are built wherever they can be economically justified. Therefore, construction of breakwater in areas that establishment of structure is disadvantageous is risen according to the change of conditions to the location for ports. In case of building gravity breakwater in such point, need that plane shape of more reasonable section permitting wave overtopping. One of the earliest methods for solving unsteady incompressible flow involving free surfaces is the MAC(Marker And Cell) method by Harlow and Welch(1965). Recently, VOF(Volume Of Fluid) method to improve several drawbacks of MAC method is suggested by Hirt and Nichols(1981) and utilized extensively in fields of hydrodynamics. This paper simulated wave overtopping phenomenon including wave breaking for permeable breakwater by numerical analysis and investigated features of wave overtopping behind structure using VOF method.
