Workshop programme

Programme of the 3rd workshop on berm breakwaters.

Berm breakwater structures

The overall objective of the research project on berm breakwater structures is to arrive at a better design basis, which will bring the design standards of berm breakwaters up to the level of design standards for other civil engineering structures. This objective will be reached by establishing an understanding of the physics of berm breakwaters...

Influence of permeability and stone gradation on Berm Breakwater stability

The influence of permeability and stone gradation on the reshaping and wave overtopping of berm breakwaters was studied as part of this research. Another aspect studied was the difference in reshaping comparing a berm breakwater constructed of two stone classes and a more stable Icelandic type of berm breakwater built of three stone classes with...

Results of physical tests done at DHI on the stability and regressionof Berm Breakwaters.

Berm breakwater structures: Final report: Research summary

A research project on berm breakwater structures was carried out with the overall objective of arriving at a better design basis. Eight European organisations from Denmark, The Netherlands, United Kingdom, Norway, Italy and Iceland participated in the joint research project co-sponsored by the European Commission under the second research and...

Note on roundhead stability analysis

Note on the roundhead stability of berm breakwaters. Recession, erosion and longshore transport are measured

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,...

Berm breakwater structures: Features of berm breakwaters and practical experience

This paper describes the features of benn breakwaters including advantages and drawbacks in comparison to traditional rubble mound structures. A review of selected practical experience with eight berm breakwaters is described in terms of typical cross-sections and key parameters (two examples from Norway. Iceland and USA, and one from Faroe...

Berm Breakwaters: Influence of Permeability and Stone Gradation

The influence of permeability and stone gradation on the reshaping and wave overtopping of berm breakwaters was studied by flume model tests. Another aspect studied was the difference in reshaping comparing a berm breakwater constructed of two stone classes and a more stable Icelandic type of berm breakwater with the largest berm stones used as...

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...

Berm breakwater trunk exposed to oblique waves

Comprehensive three-dimensional model tests with a berm breakwater roundhead and the adjacent trunk section were carried out at the Danish Hydraulic Institute (DHI) and at the Hydraulic & Coastal Engineering Laboratory of Aalborg University (AAU). This paper describes the influence of wave obliquity on the profile shape, on the initiation of...

Berm breakwater structures: Berm breakwater trunk exposed to oblique waves

The major part of the research on berm breakwaters has concentrated on the berm reshaping of a trunk section exposed to head-on waves. Recent research included aspects related to individual stone movements under perpendicular wave attack (eg Tomasicchio et al). For a berm breakwater trunk section consisting of berm stones smaller than a certain...
