Nuclear Waste Dumping in the Ocean?Is It Over?
At the Ninth Consultative meeting of the London Dumping Convention (LDC) in September, 1985, the nations of the world voted to indefinitely continue a two year moratorium prohibiting the...
An Examination of the History and Political Processes Involved in the Reclamation of Alameda Beach, Alameda, California
This paper examines the history and political processes which transformed the eroded tidal flats of the Alameda shoreline into today's Alameda Beach. The innovation and tenacity...
Environmental Compliance Inspections
No 'after construction' inspection has ever been conducted in the Corps to ascertain 'if' or 'how well' we...
Albemarle-Pamlico Sounds: Issues, Resources, and Management (
The Albemarle-Pamlico Sound complex, located in northeastern North Carolina, is the third largest estuarine complex in North America and the second largest in area in the United States....
Restoring of Butcher's Slough Estuary?A Case History
A 30-acre parcel of former lumber and plywood mills occupying original estuary and salt marsh wetlands on the northern edge of Humboldt Bay, Humboldt County, north coastal California,...
Managing the Coastal Heritage of Australia
The concept of heritage spaces as a part of open-space systems has been evolving in Australia over the last 15 years. This paper overviews the main approaches that have been developed...
Reclamation of Athabasca Oil Sand Sludge
The bulk of oil sand tailings (80 to 90%) consists of quartz sand, which is defined to be everything coarser than 44 microns. The other 10 to 20%, termed 'sludge',...
Analysis of Plastic Soil in Contact with Cavitose Bedrock
A numerical analysis has been conducted to evaluate the stress deformational response of highly plastic soils in contact with cavitose Bedrock. The numerical idealization represents the...
Building Over the Golden Gate
Charles Seim discusses the struggles of the original bridge advocates to garner support for the Golden Gate Bridge, an idea which originally met with a considerable amount of public opposition....
Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...
Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...
Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...
Mechanics of Embankment Erosion During Overflow
Thousands of dams built in the United States have a potential to be overtopped by flood flows. It is necessary to understand the mechanics of embankment erosion in order to evaluate the...
Embankment Overtopping?Case Histories
Because many existing dams are subject to overtopping, there is a need to understand embankment behavior during an overtopping event. Understanding of this behavior will allow evaluation...
Vegetal Protection of Embankments and Spillways
Recent advances in the application of tractive stress to the design of grass-lined open channels are used to develop a tentative procedure for analyzing the hydraulic performance of vegetated...
Refined Modeling to Estimate Sediment Discharge
Numerical solution of the two-dimensional turbulent flow over a train of identical dunes is obtained with the Algebraic Stress Model for closure. The effective tractive force acting on...
Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...
Evaluation and Surveillance of Concrete Bridge Structures
A number of cost-effective techniques are available for evaluation and surveillance of concrete bridge structures. The methods covered in this paper include: long-term bridge instrumentation,...
