Behavior of Wave Induced Current Around the Head of Breakwater

Abstract Breakwater is built for a specific purpose related to wave and sedimentation. By constructing the breakwater in coastal waters, the previous behavior of the wave condition is disturbed. In this study, interaction of the structure (head of breakwater) and wave induced current is simulated in order to identify the current pattern. The current pattern should be taken into account to recalculate stability of the breakwater and might be used to predict the potential of scouring around the structure. A 3D hydraulic modeling was carried out using the wave basin. The study results that the current shows its complexity as it is influenced by so many contributors, i.e. an incident wave, reflection wave, longshore current as well as the porosity of the breakwater.
