M GIS™ i i i f i dl l h• MarGIS™ is an exciting, user-friendly management tool that integrates existing numerical models into a GIS framework. It has been specifically designed for use by non-modellers to efficiently undertake water quality model simulations, execute model runs, and visualise and report on simulation results within a single environment.

• MarGIS™ has been adopted by the Northwest Region of the United Ki d E i t A ‘b t ti ’ i f lfilli th iKingdom Environment Agency as ‘best practice’ in fulfilling their

obligations under the EU Habitats Directive
