Numerical problems associated with coupling hydrodynamic models in shelf edge regions: the surge event of February 1994

摘要

A coarse grid three dimensional model of the north west European Continental shelf, and a finer grid model of the region off the west coast of Scotland and the Irish Sea are used to examine flow through the North Channel of the Irish Sea. The period of the storm event of February 1994 is considered. Comparisons of computed and observed currents in the North Channel show that the shelf wide model Can reproduce the main features of the flow, although the grid of the model is too coarse to resolve the Detailed topography in the region.
