Berms deployed at the toe of conventional breakwaters may be needed to reduce bottom settlements and to limit scour in front of the structure.

Abstract

Berms deployed at the toe of conventional breakwaters may be needed to reduce bottom settlements and to limit scour in front of the structure. Due to their influence upon the wave loads acting on the armor, the submerged berms may be also effective in increasing the stability of the armor layer, as well as of the soil-foundation system, if compared to straight sloped conventional breakwaters. This research deals with the influence of submerged berms on the wave-induced dynamic pressure in front of and beneath rubble mound breakwaters, whose detection is paramount for the evaluation of momentary liquefaction phenomenon. The present paper summarizes the preliminary results, obtained from experimental tests and numerical models.
