Abstract : This contribution builds on an existing methodology of image clustering analysis, conceived for modelling the wave overtopping at dikes from video records of laboratory experiments. It presents new procedures and algorithms developed to extend this methodology to the representation of the wave runup at crown walls on top of smooth berms.

Introduction Coral reefs not only help sustain the economy of 500 million people in tropical coastal communities (Hoegh-Guldberg et al., 2019), but also protect them from wave-driven flooding and coastal erosion (Elliff and Silva, 2017; Reguero et al., 2018), especially in the face of climate change (Storlazzi et al., 2018). Coral reefs can substantially reduce coastal flooding by efficiently attenuating ocean wave energy (Ferrario et al., 2014).
