disposal purposes. 



4. Increase our knowledge of mixing and transport processes 

 at the various Interfaces and within the estuarlne water 

 mass Itself. 



5. Determine the significance of ground water Inputs %o the estuary. 



6. Develop engineering ability to use water movements, 

 Including tidal action for estuarial flushing and bottom 

 cleansing. 



B. Sedimentation 



1. A wide range of research Is required to provide an adequate 

 knowledge of how to prevent and control the effects of 

 pollutional benthic deposits. 



2. Develop methods for mitigating the estuarlne damage due 



to dredging activity and Improve spoil disposal practices. 



3. Increase knowledge of the effects of offshore and nearshore 

 dumping. 



4. Increase knowledge of the sources and rates of sedimenta- 

 tion and of the effects of sedimentation on the ecosystem. 



C. Structures and physical modifications 



1. Determine the effects of structures and physical modifications
