Note on roundhead stability analysis

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

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 breakwaters: Hydraulic response of roundheads and trunks exposed to oblique waves

As a part of the MAST II Berm Breakwater Structures, existing data from conducted laboratory tests have been reanalised. The objective was to evaluate the effect of the longshore transpsort on both the roundhead and trunk, the ht.u,er exposed to both head-on waves and oblique inegular waves varying from 15 to 30 degrees angle of incidence. 3...

On the stability of berm breakwaters roundheads and trunk erosion of oblique waves

The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at rhe Hydraulics Laboratory, Department of civil Engineering, university of Aalborg. The object was to study the stability/erosion of the breakwater head and the trunk, the latter exposed to both head-on and oblique irregular waves. To avoid too...
