Estuarine and Coastal Modeling contains 48 papers that were presented at the Ninth International Conference on Estuarine and Coastal Modeling held in Charleston, South Carolina, from October 31 to November 2, 2005. This practical book explores the development, testing, application, calibration, validation, and visualization of predictions from estuarine and coastal models. The papers are divided into 20 oral sessions and 1 poster session featuring model application and demonstration of model visualization and systems integration. They cover various aspects of estuarine and coastal modeling, climatology and skill assessment, particle tracking, residence times and spill analysis, biogeomechanical modeling, numerical techniques, structure and methods, Nowcast/forecast systems, sediment re-suspension and transport, restoration modeling, and combined wave - current modeling.
