Deltares is an independent Dutch institute for applied research in the field of water, subsurface and infrastructure and employs over 800 scientists and consultants. Our main focus is on complex issues in deltas, coastal regions and river basins. In our urban projects, we work on the interaction between the physical system and the way a city functions. We draw on this knowledge to develop and apply innovations that contribute to urban design, spatial planning, the maintenance and governance cities. Making cities safe, healthy, productive and sustainable.
