Deltares is an independent institute for applied research in the field of water, subsurface and infrastructure. Throughout the world, we work on smart solutions, innovations and applications for people, environment and society.

Our main focus is on deltas, coastal regions and river basins. Managing these densely populated and vulnerable areas is complex, which is why we work closely with governments, businesses, other research institutes and universities at home and abroad. Our motto is Enabling Delta Life. Deltares offers for this purpose a unique combination of knowledge, experience and facilities in the field of water, soil and infrastructure.

The research that Deltares does for the built environment and critical infrastructure includes innovative strategies and solutions which focus on mitigating and adapting to the effects of climate change and aging. Moreover, to implement new designs and/ or innovative solutions, Deltares aims to integrate her technical knowledge on water, subsurface and infrastructure with governance and policymaking to solve problems in highly complex dynamic delta systems. As an applied research institute, the success of Deltares can be measured in the extent to which our expert knowledge can be used in and for society.

For Deltares the quality of our expertise and advice is foremost. Knowledge is our core business. Furthermore, we believe in openness and transparency, as is evident from the free availability of a selection of our software and models. Open-source works, is our firm conviction. Deltares employs over 800 people and is based in Delft and Utrecht.
