Tidal circulation and salinity transport in the James River and Hampton Roads estuarine system has been simulated using a three-dimensional curvilinear-grid hydrodynamic model, CH3D, developed...
Circulation Between I-664 Channel Islands, James River, Virginia
This paper compares information presently available concerning the maximum currents between the I-664 Channel Islands in Hampton Roads, Virginia, before and after construction of the islands....
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...
The Chesapeake Bay Hydraulic Model: Construction, Operation and Verification
This paper discusses significant aspects of the construction, operation, verification and testing at the Chesapeake Bay Hydraulic Model which was operational from May 1976 to August 1984....
A 3D-Stereo Graphics Interface for Operational Great Lakes Forecasts
A system for real-time predictions of Great Lakes physics and transport characteristics is now being implemented. The full 3D nature of the predictions demands accurate, high speed computer...
Re-Examination of the Coriolis Effect on the Two-Dimensional Depth-Averaged Model
In the development of the two-dimensional depth-averaged hydrodynamic model equations, a previously ignored Coriolis component in the vertical direction is retained in the governing differential...
Sensitivity of Gulf of Maine Tide Model to Depth
A 2-D tide model of the Gulf of Maine failed to produce accuracies necessary for the de-tiding of Geosat satellite data. A subsequent sensitivity analysis indicated that the model was...
Flow Separation of Currents in Shallow Water
Flow separation of currents in shallow coastal areas is investigated using a boundary layer model for two-dimensional (depth-averaged) tidal flow past an elliptic headland. If the shoaling...
On Numerical Strategies of Estuarine and Coastal Modeling
Numerous numerical models of circulation and transport for estuarine and coastal waters have been developed. A variety of numerical techniques are used by these numerical models. This...
Estuarine, Shelf, and Ocean Hydrodynamic Modelling Approaches
Estuarine, shelf, and ocean hydrodynamic modelling approaches are presented in order to explore the development of a coordinated set of models to describe the complex interactions between...
Computer Simulation of Weeks Bay, Alabama
Results of a two-dimensional, depth averaged (WIFM) mathematical model for Weeks Bay, Alabama under equatorial tide conditions are presented. Comparisons of model predicted hydrodynamic...
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...
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...
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...
