Abstract: An accurate prediction of the spatial distribution of overtopping volumes is crucial for the reliable assessment of the safety of coastal regions in response to potential wave overtopping hazards in a rapidly changing climate. Here, for the first time, we present a comprehensive suite of laboratory-scale physical modelling experiments to investigate the spatial distribution of overtopping volumes behind a composite seawall with a berm placed on a seaward slope. Test results show that the spatial distribution of overtopping water can be described with an exponential function of the distance x behind the seawall crest. A new empirical equation is proposed to estimate the spatial distribution of overtopped water behind a berm composite seawall, subjected to regular wave attack.
