data base for each structure type was 

 made based on the number of available 

 references and their ratings. Germane 

 studies in progress were identified and 

 the potential contribution to the state of 

 the art projected. 



Case histories of the impact of the 

 shoreline structures were also prepar- 

 ed. Wherever possible, the case history 

 included information about the biological 

 and physical environment before and 

 after construction of the structure, an 

 evaluation of the effectiveness of the 

 structure, and an evaluation of the im- 

 pacts of the structure on the physical 

 environment and on fish and wildlife 

 habitat. 



The text (Volume 1), the primary 

 author reference number index, the 

 keyword index, and the annotated bibli- 

 ography (Volume 2) comprise the final 

 report.
