Design and Construction - Theodore Ship Channel
Environmental impacts, greater technological capabilities, and improved evaluation techniques make the disposal of large quantities of dredge material more complex and involved. Also,...

Selection of Dredged Material Disposal Sites
Federal and state legislation regulating dredging of navigation channels along Maryland's Eastern Shore requires that local governing bodies provide the dredged material disposal...

Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...

An Offshore Mound Constructed of Dredged Material
The concept of using dredged material to intentionally construct an underwater mound was tested and confirmed at the Dam Neck Disposal Site, 4 miles offshore Virginia Beach, Virginia....

Dredging as a Remedial Method for a Superfund Site
Remedial action at the Commencement Bay Nearshore/Tideflats Superfund Site, in the State of Washington, is expected to include dredging and disposal of contaminated sediments located in...

Fundamentals of Agitation Dredging
The definition and basic principles of agitation dredging are discussed. Equipment for agitation dredging is categorized. The principles of operation, advantages, and disadvantages of...

Improved Techniques for Removal of Sediments Contaminated with Hazardous Materials
Realizing the need to improve the capabilities of response personnel in dealing with cleanup operations involving contaminated sediments, the U. S. Coast Guard and the U. S. Environmental...

Buoyant Jet Solution with Synthetic Entrainment Function
A synthetic entrainment function is proposed for buoyant jets discharged at an arbitrary angle into otherwise quiescent ambient fluids. The entrainment function consists of two separate...

Numerical Flood Routing for Natural Channels
A numerical model has been developed for simulating the propagation of a flood wave in a natural channel. Using this numerical model, the influence of the factors affecting the motion...

Boundary Element Analysis of Flow in Heterogenous Porous Media
The boundary integral equation method (BIEM) is an efficient numerical method which has been applied to a wide variety of engineering problems governed by a partial differential equation...

Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...

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,...

Using CADD for Fun and Profit
American Bridge Engineers, a Pittsburgh full service engineering, architecture and planning firm, is still exploring the full capabilities of its CADD (computer aided design and drafting)...

Micros Can't Stand Alone
Unlike mainframes, which usually come as turnkey systems, microcomputers require separate accessories. Add-ons for micros include storage devices, memory boards, video boards, communication...

Computers in the Construction Resident Office
The application of small computers to the management and control of construction projects is obvious. However, what benefits could be realized from their application in a resident office,...

Computers: The Ins and Outs of the Purchasing Contract
When purchasing computers and computer graphic systems there are 13 areas in the purchasing contract that should be investigated. These include the agreement, specification, dates, inspection,...

The Three Point Resection: An Alternate Method
When doing stadia or topographic surveying, it is not always economical or practical to establish the location of the transit or plane table via a field traverse. If three points of known...

Personnel
Recruiting, Motivating, Rewarding
Aspects of personnel management are discusased in relation to the engineering profession. The first section of these proceedings includes a report on orientation of the new employee and...

Managing Urban Transportation with Limited Resources
The objectives of this symposium are to acquaint the profession with innovative practices for managing transportation resources during a time of fiscal constraint. The ideas and approaches...

Liability in Construction Management
The concept of professional construction management has emerged and developed over the past decade in response to pressures for faster and more economical project completions. This has...
