ABSTRACT

 Drying Characteristics and Oxygen Transport In Dredged Sediments


To maintain and improve waterborne navigation, approximately four hundred million cubic yards of sediment are dredged each year by different industries in the United States.  Port dredging is done to create and maintain sufficient water depth so that ships and boats can move safely through bodies of water.  The Environmental Protection Agency detected that the sediments are contaminated and that river and harbors will require remediation.  Presently, the New York Harbor is the largest sediment cleanup technology-testing program in the United States.  This study in the New York Harbor dredged sediment is carried out to determine the drying characteristics of the sediment in the confined disposal facilities.  Confined disposal facilities are an open body of land that has been cleared to serve as repositories for contaminated sediments.  The tasks of this project included investigating the sediment pore water evaporation, shrinkage, pore collapse, and other physical characteristics when additives are added to the sediment.  In addition, measurements such as the redox conditions and oxygen penetration in the sediment were also conducted in this research.
