Abstract:

A real-time ADCIRC finite element hydrodynamic model is applied in support of the Joint Forces Exercise JTFEX off the coast of southern California 16-23 Jul 1997. A modeling strategy is designed for Camp Pendleton coastal waters and appropriate sensitivity analyses are conducted to assess initial model performance. The real-time modeling framework comprises automation of the model setup, execution, post-processing, visualization, and an interactive World Wide Web interface. Performance of the real-time ADCIRC application, including computational and manual efforts during the JTFEX, is assessed. Model computed 24-h forecasts for sea surface height during periods of light winds compare favorably with observed water levels. Several suggested improvements to the real-time forecast capability include more appropriate boundary specifications for wind-driven flow, a model restart option, and tools for merging multiple resolution data sources. The JTFEX exercise enabled transition of an ADCIRC real-time forecast system to the U.S. Naval Oceanographic Office and provided insight into operational needs and issues.
