Using GIS Techniques for Transportation Planning to Automate Compilation of Land Use Information
This paper describes a procedure used to compile land use or socioeconomic data for traffic analysis zones for input into a transportation planning model. The procedure uses a combination...

Modeling and Data Uses in Hydraulic Transport Investigations, New Bedford Estuary, Mass.
Field measurements, laboratory tests, and models were used together to make transport predictions for the sediments and dissolved materials which would be released by proposed dredging...

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...

Pre- and Post-Processing Data Management Approach for Eutrophication Model of Peconic Bay, Long Island
A pragmatic data management approach for pre-processing and post-processing of large data sets from numerical models has been applied to a coupled hydrodynamic and water quality model...

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...

Water and Sediment Quality Analyses for the New Boston Wastewater Outfall
This paper describes portions of the farfield hydrodynamic and water quality modeling conducted during preparation of the Boston Harbor Wastewater Conveyance System Supplemental Environmental...

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...

Natural System Issues in the OCRWM Program
Twenty four site characterization Issues, most of which pertain to the natural system, are presently defined in the Office of Civilian Radioactive Waste Management (OCRWM) Program for...

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...

Pipeline Design and Installation
The proceedings of the International Conference on Pipeline Design and Installation, held on March 25-27, 1990 in Las Vegas, Nevada, presents information on all aspects of pipeline design...

High-Country Hydro
The North Fork Stanislaus River Hydroelectric Development Project is a new 205 MW $267 million hydro plant in the Sierra Nevada Mountains. Completed in 1989, the project was the largest...

Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...

Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...

Slips Ahoy
Klancnik discusses the markets for marina construction in the 1990s. The past decade saw a boom in the boating industry and in the design and construction of marinas. The market will remain...
