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.

斜波攻击对带护堤光滑和粗糙堤防波顶的影响

摘要 与垂直波浪攻击相比，斜波浪攻击可以显着减少沿海结构的波浪越顶量。存在用于估计斜波对波浪越顶影响的指南。还提供了估算向海斜坡中护堤影响的指南。这些关于斜波衰减效果和护堤衰减效果的指南经常组合使用，尽管可用于这种组合衰减效果的数据有限。为了开发一种可以解释斜波和堤坝向海斜坡中的护堤的减少效应的方法，已经在波浪盆地中对具有平滑和粗糙斜坡的结构进行了物理模型测试。根据这些数据，
