Berm breakwater structures: Results of berm breakwater tests with special attention to the influence of the rock shape on the longshore transport

The report summaries the results obtained with a berm breakwater attacked by oblique waves. In the tests special attention is given to the influence of the rock shape on the longshore transport. Moreover, the reshaping berm profile and amount of wave overtopping is examined. The tests were performed in a tree-dimensional model in Jan.-Feb. 96'...

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...

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...

Hydraulic performance of berm breakwaters

Rubble mOlJnd breakwaters have been used for centuries for the protection of harbours. In many cases breakwaters were built in relatively deep water and exposed to waves too severe in relation to the size of rock used for construction. Furthermore, they were often built with a steep slope, and consequently, severe damage occurred. In some cases,...
