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: Parametric study of reshaped profile under head-on and oblique waves

In order to describe the reshaping breakwater profile, the profile has to be schematized into profile parameters. Static stability is describe by damage and reshaping breakwaters by the profile. The profile can be schematized by profile parameters such as height and length parameters. Burcharth, and Frigaard (1988) made the first systematic...

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...

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...

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,...
