detailed discussions of various specific design considerations are given 

 wherever possible, and readers are urged to consult these works. Review of 

 design procedures is necessary in this paper to place an appropriate perspec- 

 tive on simplifying assumptions made in this and other discussions of optimi- 

 zation procedures. An introduction to a number of methods now in use to pre- 

 dict damages to rubble-mound structures will be presented as tools to estimate 

 future maintenance and repair costs for a breakwater design. Similarly, a 

 discussion of methods to predict the wave transmission characteristics of 

 breakwaters will follow to show how the structure's functional performance may 

 be evaluated. The main paper will be concluded with a procedure to guide 

 planners and designers of rubble-mound breakwaters from the choice of design 

 criteria to determination of final dimensions. Appendixes will document the 

 software available to accomplish some steps of this procedure.
