Maximizing Your Use of Interactive Graphics in Transportation Simulation Modeling
The paper discusses the capabilities, through the aid of computer graphics,now that exist to take analysis and reporting of traffic simulation model studies several steps further than...

Dynamic Assignment Modelling with Trips
This paper describes additional ways in which TRIPS models time-varying, or 'dynamic' effects. These include area-wide effects as vehicles move through the network,...

A Survey of Three-Dimensional Numerical Estuarine Models
This paper surveys the existing 3-D estuarine hydrodynamic and solute transport models by a review of the commonly used assumptions and approximations, and by an examination of the methods...

Curvilinear Long Wave Hydrodynamic (CLHYD) for Tidal Circulation and Storm Surge Propagation
The objective of this paper is to demonstrate the ability of a two-dimensional long wave hydrodynamic model to simulate long wave processes in curvilinear coordinates. The series of tests...

Application of a Boundary Fitted Coordinate Hydrodynamic Model
A three-dimensional, boundary-fitted hydrodynamic model was applied in a two-dimensional, vertically-averaged mode to predict the tidal circulation in Mt. Hope Bay, a small estuary located...

Evolution of a Three-Dimensional Curvilinear-Grid Hydrodynamic Model for Estuaries, Lakes and Coastal Waters: CH3D
Traditional finite-difference models of estuarine, coastal and lake hydrodynamics and transport use rectangular Cartesian grids in the horizontal directions. In order to accurately represent...

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...

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...

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...

Application of Particle Tracking Model for Ocean Outfall Siting in New Bedford, Massachusetts
PACE, a particle tracking model, was used to assist siting studies for an ocean outfall to be built in conjunction with the City of New Bedford's proposed new secondary wastewater...

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...

Resistance Coefficient in a Tidal Channel
In applying a numerical hydrodynamic model to the tidal channel-lagoon complex around Great Sound, New Jersey, it became apparent that the model guidelines for the resistance coefficient...

Hydrodynamic Modeling on Vertically Mixed Bays
Extensive model-data comparisons of sea surface elevations and vertically-averaged velocities are performed on the Peconic Bays Estuary, New York, a system of interconnected bays where...

CSO Induced Circulation in Marine Tributaries
Pulses of freshwater flow to estuarine tributaries from combined sewer overflows (CSO) create short duration intense salinity stratification in the tributaries. An accurate assessment...

Numerical Modeling of the Vertical Salinity Distribution in Coastal Canals
A two dimensional (laterally averaged) numerical model of estuarine circulation has been developed for the prediction of the vertical salinity distribution in coastal canals. The model...

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,...

Modeling a Wind-Mixing and Fall Turnover Event on Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic model of Chesapeake Bay has been developed. Results from application of the model to one of the three data sets employed in the verification...

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...
