Coastal Tide Prediction Using the ADCIRC-2DDI Hydrodynamic Finite Element Model: Model Validation and Sensitivity Analyses in the Southern North Sea/English Channel

摘要

Details of the barotropic hydrodynamic model, ADCIRC-2DDI, including formulation of the governing equations and their numerical solution are presented. Validation of ADCIRC-2DDI predicted tidal heights and currents in the North Sea/English channel is undertaken in the context of the Tidal Flow Forum as outlined by Werner and Lynch (1988). Sensitivity studies examine the effects of nonlinear mechanisms, forms of the tidal forcing, and the behavior of various model parameters on the computed tidal response. Mesh resolution issues are also investigated in the context of tidal dynamics. Throughout this report, model experiments and the discussion of results are focused on improving understanding of the ADCIRC-2DDI hydrodynamic model and its application to coastal tide prediction.
