Objective 



Determine the magnitude and extent of effects of disposal sites on 



organisms and die quality of surrounding water, and the rate, diversity, 



and extent such sites are recolonized by benthic flora and fauna. 



Develop techniques for determining the spatial and temporal distribution 



of dredged material discharged into various hydrologic regimes. 



Determine on a regional basis the short- and long-term effects on water 



quality due to dredging and discharging bottom sediment containing 



pollutants. 



Determine on a regional basis the direct and indirect effects on aquatic 



organisms due to dredging and disposal operations. 



Develop techniques for determining the pollutional properties of various 



dredged material types on a regional basis. 



To characterize the effluent and leachate from confined disposal 



facilities, determine the magnitude and extent of contamination of 



surrounding areas, and evaluate methods of control. 



Identification, evaluation, and monitoring of specific short-term and 



more general long-term effects of confined and unconfined disposal of 



dredged material on uplands, marsh, and wetland habitats. 



Development, testing, and evaluation of the environmental, economic, 



and engineering feasibility of using dredged material as a substrate for 



marsh development. 



Development and application of habitat management methodologies to 



upland disposal areas for purposes of planned habitat creation, 



reclamation, and mitigation. 



Evaluation and testing of the environmental, economic, and engineering 



feasibility of using dredged material as a substrate for aquatic habitat 



development. 



Investigation, evaluation, and testing of methodologies for habitat 



creation and management on dredged material islands. 



Development of new or improved methods for the operation and 

 management of confined disposal areas and associated facilities. 



Development and testing of promising techniques for dewatering or 

 densifying dredged material using mechanical, biological, and/or chemical 

 techniques prior to, during, and after placement in containment areas. 

 Investigation of dredged material improvement and rehandling 

 procedures aimed at permitting the removal of material from 

 containment areas for landfill or other uses elsewhere. 

 Evaluation of physical, chemical, and/or biological methods for the 

 removal and recycling of dredged material constituents. 

 Investigation of the problem of turbidity and development of a 

 predictive capability as well as physical and chemical control methods 

 for employment in both dredging and disposal operations. 



Evaluation of new disposal possibilities such as using abandoned pits 



and mines and investigation of systems involving long-distance transport 



to large inland disposal facilities. 



Evaluation of the use of dredged material for tire development, 



enhancement, or restoration of land for agriculture and oilier uses. 



Investigation of technical and economic aspects of the manufacture of 



marketable products. 



Assessment of the technical and economic aspects of the development 



of disposal areas as landfill sites and the development of 



recreation-oriented and odier public or private land-use concepts. 



NOTE: This technical structure reflects the second major program revaluation made after the second full year of research accomplishment 

 and is effective as of August 1975.
