The Corps' Environmental Effects of Dredging Programs
The major programs addressing environmental effects of dredging and disposal that have been or are being conducted by the Corps since 1973 are: Dredged Material Research Program, Dredging...
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...
Fundamentals of Capping Contaminated Dredged Material
Contaminated dredged material disposed in subaqueous sites may be chemically and biologically isolated by covering or capping with a layer of clean material. The capping concept is simple;...
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...
Confined Disposal Area for Port Hueneme Harbor, Calif.
The U. S. Army Corps of Engineers, Los Angeles District, is responsible for maintenance of harbors along the Coast of California from Morro Bay Harbor to San Diego Harbor. As part of this...
Alternative Upland Disposal Techniques for Dredged Material in Urban Areas
The project involves the dredging and disposal of 750,000 cubic yards of soft organic silts from a 32 mile long manmade Canal that tranverses through Central New Jersey and is known as...
Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
Development of Response Plans for Toxic Spills
A plan is proposed for managing the response to a toxic spill into a river system and the minimization of its effects on water utilities, industry and the environment. As technical aids...
Numerical Simulation of the Bed Armoring Process
The stability of a river channel depends to a great extent on sediment characteristics. If the amount of sediment coming into a given reach for some reason becomes less than the river's...
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...
Willow Creek Dam--To Be or Not To Be
In Heppner, Oregon, several alternatives for flood control were considered. A concrete gravity dam constructed using roller compaction methods was selected because of the greatly reduced...
Pipe Spillway Plunge Pool Design Equations
An equation is given to determine if scour holes will beach and widen excessively. For nonbeaching scour holes, dimensionless equations are given for the progression of scour with time...
Avoiding Cavitation Damage to Hydraulic Structures
Cavitation damage often may be avoided by not allowing cavities to form. Where boundaries are not deeply submerged, their shape must be exactly correct, irregularities must be very small,...
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...
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
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...
Jordans Precast Airport
The design and construction of the New Queen Alia International Airport in Amman, Jordan required extensive innovation and site adaptation to integrate international standards with the...
