Consolidation Performance of Soft Clays: Part 1. Model
The simplified version of the soil model used in the finite element scheme is a linear anisotropic elastic model. Part 1 defines the parameters needed for the model and the laboratory...
Trends in Computerization in the Eighties
This paper addresses trends in computer-aided productivity tools for Civil Engineers in the eighties. Certain aspects of the past history, present status, and future of CAD/CAM and CAE...
Infrastructure: Money and Methods
State and local governments have started to cope with their infrastructure problems by passing bond issues, establishing infrastructure banks to centralize resources and decision making,...
Wetlands Development in Moderate Wave-Energy Climates
For the last three years springs of Spartina alterniflora have been planted on portions of Theodore Island, a dredged material island in Mobile Bay, Alabama. The purpose of the planting...
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,...
Dredging for a new Port - Puerto Bolivar, Colombia
A major coal export terminal at Bahia Portete, Colombia, is being developed as part of the Cerrejon Coal Project - North Zone, where one of the world's largest coal mines...
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...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
Modeling Effects of Toxicants on Aquatic Systems
Potential effects of chemicals on biomass production in aquatic systems are extrapolated from laboratory toxicological assays. The extrapolation requires that the effect of acute toxicity...
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...
Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...
