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...
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...
Some Considerations in Model and Field Data Selection for Circulation Studies of the James River Estuary
The major features of the circulation of the lower James River estuary are presented. The capabilities of numerical hydrodynamic models in reproducing these features are discussed, leading...
