Dredging Developments in the Canadian Arctic
The use of dredges in the Canadian Arctic in connection with oil exploration programmes has lead to the adaptation of existing and adoption of new techniques. Further development is required...
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...
An Application of Acoustic Core Analysis
This technique has shown itself to be extremely successful at Roberts Bank, in a highly variable bottom material, where shallow depths were not a significant problem, and some borehole...
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...
SCS Water Supply Forecasting Opportunities
SCS personnel have been surveying the mountain snowpack, collecting other hydrometeorological data, and providing water supply forecasts to users for nearly 50 years. Recently, the snow...
Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
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...
