Submerged Breakwaters and Bars — From Hydrodynamics to Functional Design

This paper deals with the functional design of submerged breakwaters and the associated hydro-morphodynamic impact. After presenting the advantages and difficulties of submerged structures it summarises the state of art on the hydrodynamic impact/effect for such a type of structure. The next pages describe the experimental set-up used to construct a number of large-scale mobile bed tests to further advance the knowledge on the hydrodynamics and morphodynamics associated to this structural type. The next section presents the corresponding numerical analyses, which supplement the findings of the laboratory work. The final section presents on-going work on the effect of these structures on beach profile dynamics.
