The objective of the research presented is to furnish design information for stone and dolos armor on non-overtopping breakwater trunks that are subjected to severe depth-limited breaking waves. Since it would be a mammoth task to comprehensively investigate all the different types of existing armor, this particular research effort concentrated on stone, which is a natural and economical protection when it is of sufficient size and quality to meet design constraints, and on the dolos, which
