Abstract
Oblique wave attack can significantly reduce the amount of wave overtopping at coastal structures compared to perpendicular wave attack. Guidelines exist to estimate the influence of oblique waves on wave overtopping. Guidelines to estimate the influence of a berm in the seaward slope are also available. These guidelines for the reducing effects of oblique waves and the reducing effects of a berm are frequently applied in combination, although limited data is available for this combination of reducing effects. To develop a method that can account for the reducing effects of oblique waves and a berm in the seaward slope of a dike, physical model tests have been performed in a wave basin on structures with smooth and rough slopes. Based on these data, wave overtopping guidelines for breaking waves on dikes have been validated and one of the guidelines has been extended to take the influence of oblique waves, berms and roughness into account.
