Abstract

AbstractIn the present work, a numerical model for the redesign of the existing and future ports and coastal defence structures is presented. The model is mainly based on the higher order Boussinesq equations and describes nonlinear wave transformation in the surf and swash zone, wave structure interaction, breaking wave induced currents and morphological changes. The existing model is adapted to describe climate change impacts on coastal flooding/erosion, ports and coastal defence structures. Model applications result to the estimation of: wave overtopping over the breakwaters crests, wave entering the harbour basin through diffraction, coastal erosion and storm surge/wave flooding. The model provides coastal engineers with a useful tool for the redesign of the existing coastal structures.
