Field Measurement of Hydrodynamics and Sediment Transport of the Mississippi River at Old River
Two detailed field surveys of the hydrodynamics and suspended sediment transport of the Mississippi River at the Old River Control Structure complex were completed in February and June...

Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...

Hydrodynamics and Mass Transfer on a Moving Drop of Water
The fluid dynamics and mass transfer associated with moving water drops are examined. In the first part, numerical solution of the transient hydrodynamics around and inside a drop falling...

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...

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...

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...

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...

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,...

Recent Progress on Hydrodynamic Modeling of San Francisco Bay, California
A hydrodynamic modeling study of the effects of freshwater inflow on circulation and mixing in San Francisco Bay has been underway since 1985. This paper describes the multidimensional...

Application of the U.S.G.S. DHM for Floodplain Analysis
The two-dimensional Diffusion Hydrodynamic Model, DHM, is applied to the evaluation of floodplain depths resulting from an overflow of a leveed river. The environmental concerns of flood...

Vertical Transport in the Vadose Zone by Fingering
Water containing contaminants may infiltrate through the vadose zone as a series of fingers which result from a hydrodynamic instability initiated at an interface in which a fine textured...

Discrete Element Simulation of River Ice Jams
The discrete element method provides an alternative to traditional analytical and experimental methods for studying river ice transport phenomena. In the discrete element method, the movement...
