Wave Overtopping Experiment
It is common for the local sea state in coastal waters to be a complex combination of waves due to local and recent wind (“sea”) and long period waves resulting from earlier weather systems, which have travelled many 100s of km with little attenuation (“swell”). Sea and swell may have very different directions. The CrossOver project arises from the absence of guidance on the influence of bidirectional (or ‘crossing’) seas on wave overtopping at coastal defences. Through a physical model study carried out in the Delta Basin, the “CrossOver” project is beginning to fill this gap in the knowledge.
