Wave action on rubble mound breakwaters: The problem of scale effects

The present report, produced within the framework of the EU funded project DELOS, attempts to recognise and analyse main scale effects in the physical modeHing of rubble mound breakwaters used in offshore and coastal engineering. Scale effects appear in physical modeHing because the ratios between the farces of interest, as present in prototype,...

Reshaping breakwater: Description of the profile evolution / Irregular wave induced forces on armor unit on berm breakwater

In order to develop a model able to describe how berm breakwaters reshape under the attack of waves, a large quantity of data from 2D and 3D tests was collected and arranged in a database. The data were first standardised, and since data come from models with very different size, all the lengths were scaled with the nominal diameter (Dn50) of...

Reshaping breakwater: Profile parametrisation

Berm or reshaping breakwaters represent a relatively new -type of wave barrier; more precisely the conscious acceptation of stone movement during reshaping and of the eventual dynamic equilibrium of the units in the exposed mound is new. Stones of the armour layer are accepted to move under the wave attack until a new equilibrium of the seaward...
