AbstractThe upgrade of existing coastal defense structures by including crown walls and parapets may represent an effective and economic solution to reduce the wave overtopping discharge. Recently, a coefficient gs_GP for the parametrization of the effects induced by berms or promenades, crown walls and parapets on the average q has been developed. The formula for gs_GP was obtained from the Genetic Programming (GP) technique and was conceived to be included in the q formulae by EurOtop Manual (2018). The formula has been applied so far only to smooth dikes with crown walls. The aim of this contribution is to investigate the extension of the formula for gs_GP to a wider range of coastal structures, such as crown walls on top of rubble mound breakwaters and vertical seawalls. The ultimate objective is to provide a new design factor to be used in the EurOtop formulae.
