Wave overtopping at caisson breakwaters reduces significantly under oblique wave attack compared to perpendicular wave attack. In this video physical model tests are being performed in the high-tech Delta Basin at Deltares to develop new guidelines for the influence of oblique wave attack on caisson breakwaters under sea and swell conditions.

Recurved parapets can reduce the amount of wave overtopping. Adding a recurved parapet to an existing breakwater can be a suitable climate adaption measure in case of unforeseen sea level rise.

However, the effect of a recurved parapet reduces for oblique waves. For simultaneous sea and swell conditions with different wave directions a method is proposed to account for the presence of swell.
