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...
Plant Bioassay of Contaminated Dredged Material
Contaminant mobility from a contaminated saltwater sediment placed in flooded and upland disposal conditions was studied in the greenhouse. Spartina alterniflora was grown in contaminated...
A Biogeochemical Evaluation of Disposal Options
This paper briefly reviews some of the factors that should be considered in selecting an environmentally sound disposal method for contaminated sediments on the basis of the biogeochemical...
Evapoconsolidation in Fine-grained Material
The increased difficulty of obtaining land needed for confined disposal of dredged material and phosphatic clays highlights the need to assess alternative disposal measures by accurately...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
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...
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,...
Abrasion Resistance of Polyethylene Dredge Pipe
In recent years there has been a slow but steady increase in the number of dredges using high density polyethylene (HDPE) pipe in discharge lines. HDPE's increased popularity...
Settling of Dredged Material Slurries
Most environmental engineers, accustomed to dealing with clarification of suspensions containing approximately 150 mg/1, find it difficult to comprehend dredged material slurries, in which...
Current Issues in Rock Dredging
An attractive alternative to the use of explosives for deepening shipping channels is the improvement of the rock cutter suction dredger. But, assessing the capability and design parameters...
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...
Dynamic Reliability Models for Hydraulic Structures
In addition to the determination of capacity and layout of hydraulic structures under normal design, one other important but related task that faces engineers is the evaluation of reliability....
Upper Hudson River Valley Dam Break Model
In order to determine areas of inundation due to the failure of Conklingville Dam, a dam break analysis was performed, and the resulting outflow hydrograph was routed through the downstream...
Accurate Computation of Nonlinear Advection
Advection, the transport of a quantity by the mean velocity, is a process which appears in virtually all equations of free-surface hydraulics. The demonstrated accuracy and efficiency...
Leaching Analysis of Coal Mine Spoil Material
Arch Mineral Corporation has conducted a column leaching study to analyze the leaching characteristics of surface coal mine spoil material in order to predict post-mining groundwater quality....
Ice Block Stability
A simple formulation of the forces acting on an ice block in contact with an intact ice cover is presented. Underturning of the ice block is the assumed mechanism by which the block is...
Simulation of River Ice Cover Growth and Decay
A model of ice cover thermodynamics was used to simulate ice growth and decay along the international section of the St. Lawrence River for the winter of 1980-81. At the air-ice interface,...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
Superplasticizers: Reducing Water in Concrete
Superplasticizers or high-range water reducers are new types of chemical admixtures which when incorporated into concrete can cause significant increases in its slump but without any loss...
