20. ABSTRACT (Caixttaue eat reveram sil£s Ft n ece s eaty and. Identity by block number) 



This study evaluates the changes in intertidal and shallow subtidal sand- 

 bottom infaunal populations in response to the addition of approximately 

 765,000 cubic meters of dredged material added to an eroded beach at Imperial 

 Beach, California. A sampling design utilizing small sampling units and 

 extensive replication was effective in generating reliable numerical estimates 

 of infaunal densities and diversity.
