Abstract

The impact of a solitary wave on an obstacle of square geometry was investigated, using a numerical model capable of treating arbitrary free-surface configurations. It was found that the computed loadings and overpressures were strongly dependent of the details of the wave/obstacle geometry at impact conditions. The loadings produced by an impinging breaker were about twice as strong and the maximum overpressure on the obstacle was about three times stronger, than those produced by non-breaking waves. 1 Introduction The impact of breaking waves on offshore and coastal protection structures creates strong localised overpressures. The intensity and location of such loadings depends on the geometry of the wave at the instant of impact
