II. REVETMENT ARMOR FACE TYPES 



Revetments have been built of a variety of materials, including rock 

 and concrete which are the most durable in water. From the numerous 

 revetment designs, both tested and untested, 25 alternative revetment 

 types were selected for presentation in this report. These revetments, 

 summarized in Figure 2, could be constructed from materials available in 

 most areas. Additional information on the merits and performance of the 

 25 revetments is in the Appendix.
