WAVE LOADS ON SEADYKES WITH COMPOSITE SLOPES AND BERMS

This paper deals with investigations on loads from wave-induced shock pressures on seadykes with composite slopes and berms. The investigations have been done with large scale laboratory tests, using different wave climate characteristics (regular waves, PM - spectra and field spectra). Two different types of dyke cross-sections have been investigated: one with an upper slope 1:6 and a berm in front, and the other one with composite slopes 1:3 in the lower part and 1:6 in the upper part. The presented results were discussed with respect to the influences of wave climate, of absolute waveheights and of geometrical conditions.
