Abstract
An extensive research on stability of statically and dynamically stable rock slopes and gravel beaches was reanalysed and focussed on berm breakwaters. Berm breakwaters are initially dynamically stable under severe wave attack, but become more or less statically stable after reshaping. The effects on the seaward profile of wave height, period, storm duration, spectral shape, initial slope, rock size, rock shape and grading, water depth and angle of wave attack, are described in a qualitative way. Relationships between these variables and the profile parameters are described, leading to a computer program. This program was verified with independent data of berm breakwaters from various international institutes. The program showed to give a good prediction of the behaviour of the seaward slope of berm breakwaters and can, therefore, be used as a conceptual design tool.
