Long-Term Fate of PCB Contamination in the New Bedford Harbor, Massachusetts, System
The transport and fate of polychlorinated biphenyls (PCBs) at the New Bedford Harbor Superfund site is modeled using a three-dimensional hydrodynamics and sediment-contaminant transport...
Circulation and Transport Modeling in New Bedford Harbor
Three-dimensional hydrodynamics and mass transport were simulated in the New Bedford Harbor, Massachusetts, area in support of a combined sewers/sewage outfall facilities planning project...
An Eulerian-Lagrangian Model for Sediment Transport in Estuaries
We describe a new depth-averaged numerical model for the simulation of the fate of sediments in estuaries. The model, denoted ELAsed, includes the following distinctive characteristics:...
A Field and Modeling Study of Fine Sediment Transport in Shallow Waters
As part of a major effort to understand and quantify the phosphorus dynamics in Lake Okeechobee, the transport of fine sediments has been studied by combining numerical modeling with an...
Siting the New Boston Harbor Outfall: Near-Field Analysis
In the near-field analysis for Boston's proposed Deer Island outfall to Massachusetts Bay, multiple initial dilution calculations were applied to estimate the frequency distribution...
Calibration of a Transport Model Using Halocarbons
A field study was conducted during April 1987 in which the concentrations of volatile halocarbon tracers, discharged from two existing outfalls, were measured throughout Boston Harbor...
Boundary Fitted Estuarine Water Quality Model
A two-dimensional, vertically-averaged boundary fitted coordinate pollutant transport model was developed for application to estuarine and coastal sea regions. The governing convective-diffusion...
Contaminant Loading from Fox River to Lower Green Bay
The heavily industrialized lower reach of the Fox River, downstream of the DePere Dam, and lower Green Bay, Lake Michigan, are modeled. Hydrodynamics and contaminant transports to the...
Three-Dimensional Modeling of Pollutant Transport
A numerical model for pollutant transport in coastal waters has been developed in x-y-z-t space. The simplicity of a fixed Eulerian mesh and a computationally efficient Lagrangian approach...
High Level Radioactive Waste Management 1990
The proceedings of the first annual Conference on High Level Radioactive Waste Management, held on April 8-12, 1990, Las Vegas, Nevada, provides information on the current technical issues...
Privatization in Transportation Financing
Since early in this century, financing for transportation has involved both private and public funds. For highways, monies provided by public or government agencies have come largely from...
Portland's Light Rail: A Successful Public Private Partnership
During its first year, Tri-Met's Light Rail service, MAX, carried twice as many riders as originally projected. What is generally not understood is that MAX is more then a...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
The paper reviews the experience of the Chicago Transit Authority's partnerships with the private sector. The funding, space, design, construction and operation components...
Motivation: Harnessing the Private Sector's Interest in the Public Agency Project
Today's public works projects are being conceived, planned, and constructed with increasing difficulty as funding becomes more illusive. The Houston Metropolitan Transit Authority...
Private Participation Made Easy in Small but Smart Transit
The maturing field of electronically 'smart' people movers offers the possibility of urban transit linkages which are smaller in scale, less demanding to operate,...
The Magnetically Levitated Transport System TRANSRAPID?Characteristics and Aspects of Application
After a development of less than two decades the magnetic levitation TRANSRAPID is virtually ready for revenue service since 1985. The service has been continuously tested since 1985 on...
Public-Private Relationship in Transportation Development
The paper explores the mechanism and development of public-private partnership which has resulted in the participatory growth of transportation projects in the Portland Metropolitan area....
South Boston Piers Transit Project
The Massachusetts Bay Transportation Authority (MBTA) is proposing to construct a new transit connection between downtown Boston and the South Boston Piers area. The MBTA has worked with...
Financing Transit: Benefit Assessment in Los Angeles
The Southern California Rapid Transit District (SCRTD) has successfully used benefit assessment to fund a portion of the Los Angeles subway project and to provide the critical private...
Public/Private Partnership?The French Example: The Toulouse Metro Project
Faced with a continuing great demand for urban public transportation, the French public authorities have, for several years, been looking for new sources of financing. Concerning urban...
