Case History: North Slope Alaska Hydraulic Dredging
Alaska's North Slope Borough, with the aid of dredging machinery consultant Michael Weston, and geotechnical consultant Rittenhouse-Zeman & Associates, has pioneered...

Surface Runoff Water Quality from Contaminated Dredged Material Placed Upland
Bioassay and associated tests have been developed and are being refined to assist in the evaluation of the environmental impact of dredged material disposal alternatives. Simulated rainfall-surface...

Evaluating the Water Quality Significance of Dredged Sediments
In the mid-1970s, the Corps of Engineers and the US EPA developed several laboratory evaluation procedures, the elutriate test, bioassay/toxicity tests, and bioconcentration tests, to...

Environmental Management Problems of Dredged Material Islands in the Tampa Bay Area
Between 1977 and 1982, four new islands were created in Hillsborough Bay as part of the Tampa Harbor Deepening Project. The islands are now 3-7 years old. They exhibit striking differences...

Safe Landfilling of Contaminated Dredging Spoil
This paper deals with the assessment of the expected emissions of toxic substances from highly contaminated harbor dredged material. The material in question arises from the canal between...

Seasonal Restrictions on Bucket Dredging Operations
Seasonal restrictions are sometimes imposed on bucket dredging operations in response to concerns for potential impacts of sediment resuspension on various biological resources. The available...

Aquaculture in Dredged Material Containment Areas
The beneficial use of active dredged material containment areas through aquaculture appears to offer, under certain circumstances, benefits to the Federal government, municipal and industrial...

Dredge Automation: The State-of-the-Art
Automated control systems are being developed and applied to enhance the productivity and cost-effectiveness of dredges. Referring particularly to hydraulic type dredging plants, the functions...

Linear Programs for Dredging Management Decisions
Recurrent economic concerns facing decision makers in the dredging industry are considered. Problems related to contract bidding, project planning and resource utilization are formulated...

Design of Monroe Harbor, MI Confined Disposal Facility
Confined disposal of polluted maintenance dredgings in the Great Lakes was authorized due to the 'closed system' nature of the receiving waters. Each harbor judged...

Activity-Based Evaluation of Potential Bioaccumulation from Sediments
Sediment bioaccumulation potential evaluations can be improved by a two-level approach. Chemical analysis of sediment interpreted using phase-activity considerations in first-level evaluations...

Use of Scientific Data for Management of Dredged Material Disposal in New England
Management of dredge material disposal in New England is closely attuned to regulatory mandates and is significantly supported by scientific findings and contributions of the Disposal...

Dredging Guidelines for the Great Lakes
The International Working Group on the Abatement and Control of Pollution from Dredging Activities was established in November 1972 in compliance with the Great Lakes Water Quality Agreement....

Design of Confined Disposal Areas for Retention of Contaminants
Dredged material which is unsuitable for disposal in open water due to the presence of contaminants is normally placed in confined disposal areas. The quality of effluent discharged from...

Ten Years of Long-Term Dredged Material Disposal Planning in the St. Paul District
Long-term dredged material disposal planning for the Upper Mississippi River by the St. Paul District had its beginnings with the Great River Environmental Action Team study (1975-80)....

Dredged Material for Backbarrier Salt Marshes
Gulf Coast barrier islands, especially those fronting the Mississippi River Delta, are eroding at a rapid rate. Natural subsidence caused by consolidation of Recent deltaic deposits and...

Aquatic Bioassays in Dredged Material Management
Dredged material ranges from gravel and coarse sand to fine silts and clays, and may be free of contaminants or highly contaminated with a variety of chemicals from industrial, municipal,...

Dredging as a Remedial Method for a Superfund Site
Remedial action at the Commencement Bay Nearshore/Tideflats Superfund Site, in the State of Washington, is expected to include dredging and disposal of contaminated sediments located in...

Long-Term Management of Confined Disposal Areas
Systematic management of confined dredged material disposal sites is becoming increasingly necessary as competition for land use intensifies in regions in which most dredging projects...

Impact and Mitigation: LA/LB Landfill Plan
Mitigation planning in U. S. ports has primarily been on a project by project basis, an approach that is costly and ineffective. This paper reports on a biological impact assessment and...
