A GIS pre-processor for pollutant transport modellingA GIS pre-processor for pollutant transport modelling Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-092005enA GIS pre-processor was developed to produce bathymetric grids and shorelines for open and closed boundary as input to a three-dimensional hydrodynamic/pollutant transport model to simulate the currents and pollutant transport in lakes and coastal areas. The pre-processor operates within ArcView GIS and can read hydrographic files in different formats. The use of this GIS module facilitates the implementation of different pollutant transport scenarios, which in turn can significantly contribute to the decision-making process concerning one of the most contemporary environmental problems. The applicability of the pre-processor is illustrated through a case study on Suda Bay, located in Crete, Greece.http://creativecommons.org/licenses/by/4.0/Environmental Modelling amd Software 120 55–68 Tsanis Giannis Τσανης Γιαννης S.
