APPENDIX B 



MATERIAL CHARACTERISTICS 



Materials used to construct permeable breakwaters are discussed in this 

 appendix. Each material is identified by a circled letter and shown on the 

 breakwaters where it was used in Appendix A. Figure B-1 includes photos of 

 samples of the various materials (material F, not shown, is similar to A and 

 B) . Some basic parameters, such as weights, diameters, and porosities, are 

 shown in Table B-1. The weight distribution of each of the materials is 

 given in Figure B-2.
