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...
RCC Dam Incorporates Innovative Hydraulic Features
An overview of the features of Monksville Dam is presented, with emphasis on the hydraulic components of the project. This 150-foot (45-meter) high roller compacted concrete structure...
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....
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...
Alluvial Fans: Novel Flood Challenge
After disastrous floods hit Cabazon, Calif., engineers faced the challenge of balancing concerns about protecting property and life (by limiting or prohibiting construction) against the...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Dredging and Dredged Material Disposal
Waterborne commerce is a major factor in the economy of many countries. Because waterborne commerce depends on the ability of nations to provide adequate navigation channels to transport...
Measurement of Hydrographic Parameters in Large Sand-Bed Streams from Boats
This report concentrates on the state-of-the-art in the field documentation of the existing channel geometry, plus the concurrent stream flow and sediment transport characteristics, prevailing...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
