DESTRUCTION CRITERIA FOR RUBBLE-MOUND BREAKWATERS

Adelkis J. Rogan

Abstract


The general purpose of the author's research undertaken in the "Laboratoxre National d'Hydraulique" was to study wave action on rubble-mound breakwaters with regular (periodic) waves on the one hand and irregular (random) wind generated waves on the other, and to compare the effects of these two types of waves by use of the storm duration t. With a first series of periodic waves experiments we have obtained the destruction of the breakwater's cover-layer for different storm durations t, by varying H and T. The mass of armor units remained constant. The angle of the slope, according to the seaward equilibrium profile could be considered as constant.
