Coastal modelling with a GIS bathymetric module

A 3D hydrodynamic/pollutant transport model was used to simulate the currents and pollutant transport
in coastal areas. The bathymetric and shoreline data was provided to the model via a GIS module
that operates in the ArcView GIS environment. The module is efficient and capable of generating
bathymetric rectangular grids and shorelines of different resolution for open and closed boundary scenarios
that can automatically be read by the coastal model. This ability could improve the basic patterns
and relationships of the model such as grid dependency. The functionality of the 3D model with the
GIS module is illustrated in a number of coastal areas in Greece.
