This report discusses the application of detached single and segmented 

 breakwaters for shore protection and beach stabilization. Four single de- 

 tached breakwaters and six segmented breakwater systems in the United States 

 are reviewed. Based on this review, the performance of breakwaters in other 

 countries, and general knowledge of coastal processes, the implementation and 

 design of breakwaters are discussed. General guidance is presented for the 

 design of detached breakwaters and several design examples are presented.
