Rubble mound breakwaters
WebbThere are several kinds of these structures. xv Rubble mound breakwaters belong to the most popular breakwater type in the world. They deserve this popularity due to their easy construction on most soil conditions, by their progressive damage future instead of a sudden collapse and their relatively easy repairment possibilities. WebbRubble Mound Design ¶ Two designs are elaborated on. First a conventional rubble mound breakwater with rock as armour layer and secondly, one with armour units as armour layer.
