Title: Prediction of Instantaneous Currents in San Diego Bay for Naval Applications • Introduction • Purpose • Method • Results • Application • Conclusions
San Francisco Bay • New York/New Jersey Harbor • Houston/ Galveston • Tampa Bay • Chesapeake Bay • Narragansett Bay • Soo Locks • Los Angeles/Long Beach • Delaware River and Bay • Tacoma • Port of Anchorage • New Haven
Purpose • Resolve littoral environmental prediction problems encountered from Operation Iraqi Freedom. • Verify Water Quality Management & Analysis Package (WQMAP) for NAVO .
Method Utilizing WQMAP to: • Design hydrodynamic model for predicting the tidal driven currents of San Diego Bay. • Compare modeled results to NOAA tide table predictions • Provide operational windows for operations limited to water current thresholds for ANY location within the bay.
Method – What is WQMAP? • Integrated hydrodynamic and water quality modeling system designed for use within coastal and fresh water environments. • Consists of three basic components: • boundary-fitted coordinate grid creation module • a 2D or 3D hydrodynamic model • water quality or pollutant transport model • Executed on a boundary fitted grid system. • Also able to be operated on any orthogonal curvilinear grid or a rectangular grid, which are special cases of the boundary fitted grid.
Method – Why WQMAP? • Hydrodynamic modeling program. • Geospatial Information System (GIS) • Easy to use graphical user interface (GUI).
