BREAKING WAVE EVOLUTION OVER MONOLITHIC SUBMERGED BREAKWATERS: AN EXPERIMENTAL AND NUMERICAL STUDY

摘要

The present paper presents an experimental and numerical study of partial wave reflection and transmission for monolithic rectangular submerged breakwaters located in the nearshore region. The study is based on large-scale experiments that have been conducted in Universitat Politecnica de Catalunya, Laboratory de Ingeneria Maritima (LIM-UPC). The most important conclusion, deduced by the experiments, is that the main energy dissipation mechanism is the wave breaking due to the presence of the structure. The numerical approach of the problem is based on a higher order Boussinesq type of equations. The comparison between model results and experimental data shows that the model is able to describe breaking and non breaking wave deformation passing over a submerged breakwater.
