Spills: The Human-Machine Interface State of Our Knowledge
The International Joint Commission on the Great Lakes has entered into agreements on Great Lakes water quality. Many of the 3000 significant spills that occur in the Great Lakes Basin...

Bio Bonanza?
Bioremediation was used on a portion of the Exxon oil spill, causing the popular press to take notice of the ability of bugs to eat away at oil and, possibly, toxic wastes. The Alaskan...

Applying TRANPLAN to Assist Air Quality Impact Analysis
Environmental analysts have been using the plotting capabilities of TRANPLAN, a transportation planning software package, to facilitate the analysis of air quality impacts of the Boston...

Scheduling Fixed Route Bus Services Using Simulation
The paper discusses the development and applications of a Monte Carlo simulation Program (BUS - MONITOR) for estimating and evaluating the quality of service of fixed route, many to many...

Dispersion Analysis of the Dartmouth, MA Municipal Sewage Outfall Off Salters Point
The water quality impacts of the existing and proposed upgraded Dartmouth, Massachusetts Wastewater Treatment Plant on the Salters Point region of Buzzards Bay were examined through the...

Development of a Three-Dimensional Hydrodynamic Model of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields and vertical eddy diffusivities to a 3D water quality model of the bay. The water surface,...

Interfacing Three-Dimensional Hydrodynamic and Water Quality Models of Chesapeake Bay
A methodology is presented for interfacing a three-dimensional, time-varying, intratidal hydrodynamic model with an intertidal water quality model of Chesapeake Bay. First-order Lagrangian...

Calibrating the Chesapeake Bay Water Quality Model
A eutrophication model comprised of twenty-two state variables including three algal groups and multiple species of carbon, nitrogen, phosphorus, and silica is described. Equations governing...

Modeling Residual Chlorine in the Potomac Estuary
This paper presents the development and application of a two-dimensional finite element hydrodynamic and water quality model, termed Neleus, to assess chlorinated discharges to the Potomac...

Modeling Circulation in Los Angeles-Long Beach Harbors
A three-dimensional hydrodynamic model was applied to Los Angeles-Long Beach Harbors to determine tide- and wind-induced circulation. The model was calibrated and verified successfully...

Two-dimensional Modelling of the Bristol Channel, UK
A two-dimensional depth-averaged numerical hydrodynamic model of the Bristol Channel and Severn Estuary has been developed to investigate the effects on water quality of existing and new...

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...

Eutrophication and Nutrient Enrichment in Peconic Bay: Numerical Model of Historical Conditions of the Mid-1970s
In response to water quality and resource management issues triggered by the brown tide bloom of 1985-88 in the embayments of the Peconic estuary of Long Island, New York, a coupled hydrodynamic...

Eutrophication and Recurrent Hypoxia in the New York Bight: A Synthesis of Historical Data and a Numerical Model of the 1976 Anoxic Event
As a result of oceanographic programs conducted over the past four decades, a large historical data base is available, and has been used, to document areas of recurrent hypoxia and high...

Bay-Wide Model Studies for the Boston Ocean Outfall Siting
Oceanographic data and numerical models were used to evaluate candidate diffuser sites to discharge effluent from Boston's planned secondary treatment plant. The study showed...

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...

Receiving Water Modeling for CSO Investigations in Boston Harbor
The computer models QUAL2EXP and TEA/ELA were used to model Combined Sewer Overflow (CSO) remediation alternatives in Boston Harbor and its major tributaries. The models were adapted to...

Integrating Hydrodynamic and Water Quality Models for Patuxent Estuary
A two-dimensional mass transport model has been developed to integrate a hydrodynamic model and a water quality model for the Patuxent Estuary, Maryland. In this study, a two-dimensional,...

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...
