16. Abstract (Limit; 200 words) 



Literature about the impacts of navigational dredging on fish, other aquatic biota, and 

 wildlife is reviewed. Also included are types of dredging equipment, characteristics of 

 dredged material, evaluation of dredged material pollution potential, and habitat 

 development and enhancement opportunities arising from dredged material disposal. The 

 review contains a breif discussion of the state of knowledge and refers the reader to 

 pertinent literature for additional information. The discussions about impacts and 

 habitat development are divided into "Coastal Waters" (including disposal in estuarine, 

 continental shelf, and deep ocean waters) and "Rivers." A limited discussion of the 

 "Great Lakes" is included as an Appendix.
