Program NGIT
3 November 2014
Main goals:
• Deltares provides state-of–the-art models, tools
and information systems to support
management of ecological and chemical quality
of water soils and sediments
• Deltares works with others in open source
software communities to exchange knowledge
and jointly develop models and tools.
