ACCRETION BEHIND SINGLE OFFSHORE BREAKWATER

This study notes that the main variables in evaluating apex postion of a salient behind a single breakwater parallel to the shore with waves normal to both are its length and distance offshore. Because the shape of the salient is related to wave diffraction patterns, the apex distance from the breakwater on its centerline, its radial distance, and angle from the tip of the breakwater are all useful measurements when related to the two main variables mentioned. It is also noted that values of breakwater length to distance offshore have been established for the limting conditions of tombolo and zero salient formation. Between these two extremities, the extent of salient accumulation in equilibrium state can be determined quantitatively for designing a single offshore breakwater.
