Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...
Wetland Creation in Baltimore Harbor
Three areas of Baltimore Harbor were examined for use as wetland sites by Interstate Division for Baltimore City. Each site presented unique and interesting challenges to design. Economic...
The London Dumping Convention and Its Role in Regulating Dredged Material: An Update
The United States is signatory to an international treaty that is implemented through the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London...
Tampa Harbor Florida Deepening Project
Tampa Harbor is one of the largest dredging projects ever undertaken by the Corps of Engineers. The major features of the deepening project which presented the greatest problems were the...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
Toxic Contaminant Uptake in Dredged Sediment Marshes
Dredged sediments from the proposed enlargement of the Lower Mississippi River from Venice, Louisiana to the Gulf of Mexico would be primarily utilized to create up to 28,000 hectares...
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...
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...
Sediment Resuspension Due to Dredging and Storms: An Analogous Pair
The physics of resuspension is represented by the response of the sediment to an applied stress, either dredging operations or storm winds. In either case, once the sediments are mixed...
Effects of Dredging and Dredge Spoil Disposal on Fisheries Resources in the New York State Barge Canal
The New York State Department of Transportation initiated a study in the summer of 1982 in the New York State Barge (Erie) Canal in the vicinity of Rochester, N. Y. The purpose of the...
Environmental Legislation Impact on the Port of New York and New Jersey
Environmental legislation since 1972 has resulted in an extensive evaluation of dredged material disposal alternatives for New York Harbor navigation projects. Consideration has been given...
Sediment Resuspension from Dredging Activities
Dredges are a logical choice for removing contaminated sediments from our Nation's waterways. Historically, the dredging industry has emphasized increased production in an...
Dredge Cutterhead Flow Processes
Feasibility studies of new dredge intake and cutterhead shielding techniques were conducted to improve hydraulic cutterhead dredge performance. Simple modification of the suction mouth...
PCB Contaminated Sediments from Petit-de-Grat, Canada
In Canada, ocean disposal of dredged materials is regulated by the Ocean Dumping Control Act. Included within the schedules of regulated substances are organochlorine compounds, such as...
Dispersal of Wastewater in the Ocean--A Cascade of Processes at Increasing Scales
An engineering system for marine waste disposal is described. Design decisions are based on broad categories of input information: the complete description of the waste to be discharged;...
Mixed Layer Modelling of Stratification in Lakes
Mathematical models for vertical heat transfer processes in lakes and reservoirs are grouped into two classes: diffusion models and mixed layer models. In recent years much of the progress...
Effects of High Sediment Concentrations on Velocity and Sediment Distributions
Several classifications are required to describe sediment-transporting flow. The flow may be turbulent or laminar, Newtonian or non-Newtonian, and may also have a uniform or nonuniform...
High Sediment Concentrations Require High In-Channel/Supply of Sediment
Flows with high sediment concentrations (greater than 10 percent by weight) most commonly occur either as debris flows in steep channels throughout the world, or as hyperconcentrated flows...
Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...
