Analyzing Larval Fish Distributions Using Hydrodynamic and Transport Modelling
Port Moller is a major spawning ground for Pacific herring. Coincident with extensive larval sampling in the estuary, data required for simulating three-dimensional hydrodynamics and transport...
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
An Energy Based Model for Coastal Bays and Lakes
The North American Great Lakes have numerous tributary bays and small lakes along their coastline that open directly to the Great Lakes through natural or engineered channels. As a consequence...
Modeling the Seasonal Circulation in Massachusetts Bay
An 18 month simulation of circulation was conducted in Massachusetts Bay, a roughly 35 m deep, 100?50 km embayment on the northeastern shelf of the United States. Using a variant of the...
Linking Hydrodynamic and Biogeochemical Transport Models for Estuarine and Coastal Waters
Methodologies for linking estuarine and coastal hydrodynamic and biogeochemical transport models are reviewed and evaluated. The central premise of the review and evaluation is that intratidal...
Comparison of Eulerian-Lagrangian, Random Walk and Hybrid Methods of Modeling Pollutant Transport
An Eulerian-Lagrangian, a random walk, and a hybrid model were compared in terms of their accuracy and efficiency in simulating two-dimensional pollutant transport. Computer experiments...
A Field and Modeling Study of Residual Circulation in Sarasota Bay and Tampa Bay, Florida
Based on analysis of current data at three distinct locations within the Sarasota/Tampa Bay system, we defined the residual circulation patterns and the relative influences by tides, wind...
Application of WQMAP to Upper Narragansett Bay, Rhode Island
