Berm breakwater structures: Roundhead stability of berm breakwaters / Reshaping breakwater - Longshore transport and recession of the berm

For berm breakwaters as compared with traditional rubble mound breakwaters, special measures have to be taken for the breakwater roundhead. If stone displacements occur on a roundhead, the stones will be moved in the wave direction and will loose most of their stabilising effect. A point of special concern is whether, and under which conditions,...

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...

Berm breakwater structures: Roundhead stability of berm breakwaters

For berm breakwaters as compared with traditional rubble mound breakwaters, special measures have to be taken for the breakwater roundhead. If stone displacements occur on a roundhead, the stones will be moved in the wave direction and will loose most of their stabilising effect. The major part of the research on berm breakwaters has...

Stability of toe and scour protection

Local scour can occur at a breakwater constructed on a sandy seabed and may endanger the overall stability due to sliding of the main armour layer if the toe and scour protection is failing. The scouring pattern is a function of the water depth, wave conditions, sediment characteristics, and breakwater configuration and reflection...

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...
