This report discusses design criteria, design procedures, and practical 

 considerations involved in planning, design, and construction of rubble-mound 

 breakwaters. Currently available methods for estimating rates of damage to 

 breakwater armor and for predicting wave transmission characteristics are also 

 described. Using information typically available today to most breakwater 

 designers, a step-wise procedure is presented which can identify an optimum 

 breakwater cross section, both in terms of structural integrity and functional 

 performance.
