Employer value proposition

If you ask our employees: what does working at Deltares mean to you? Four important pillars come up. These are our employer value propositions. Below we will explain their meaning.

Knowledge and Innovation

The challenges we face now and in the future demand innovative solutions. For this reason, we do scientific research, build test set-ups, test in our Delta flume and stand with our boots in the mud to test in the field. This is how we achieve smart innovations and useful solutions for people, the environment and society, such as the Coarse sand barrier developed by Deltares. A technology that works faster, cheaper and more sustainable than the traditional approach to reinforce dikes.


At Deltares we work in international, multidisciplinary teams. Not only with colleagues who are leaders in their field, but also with partners and clients. Colleagues have different backgrounds and disciplines such as hydrologists, urban planners, ecologists, economists and morphologists. We make our knowledge usable for others. We share this knowledge with a ‘dare to share’ philosophy that offers us opportunities to do even better and to learn from each other.


Our work has impact on society. We look for example at the consequences of climate change: what measures are needed when an accelerated sea level rise scenario arises? We map the consequences of cyber attacks on water safety. And we are investigating how we can reduce the impact of plastics on our environment, health and society. All projects in which we ensure that deltas remain livable and safe, also for future generations!

Deltares gives you the opportunity to use and develop your talents. Working at Deltares means freedom to shape your work within our strategy. It requires pro-activity, cooperation and entrepreneurship. Nothing is impossible at Deltares!

The origins of Deltares

Deltares was established in 2008 after the merger of GeoDelft; Delft Hydraulics; parts of TNO Built
Environment and Geosciences and parts of the specialist services RIZA, RIKZ and DWW of
Rijkswaterstaat. The establishment of a research and innovation centre for delta issues was vitally
important in order to keep the vulnerable and flood-sensitive Dutch delta liveable in a sustainable
way. The aim was to advise both the government and the business community and to combine and
strengthen the knowledge available in the Netherlands so that innovative solutions could be found
to address the consequences of climate change. Deltares was also expected to play an important
role in providing international access to Dutch knowledge in the field of water management.
Deltares is an independent applied research institute in the area of water and subsurface. 

We are involved throughout the world in smart innovations, solutions and applications for people,
environment and society. We focus primarily on deltas, coastal regions and river catchments.
Managing these densely-populated and vulnerable areas is complex and so we work closely with
government authorities, commercial companies, research institutes and universities in the
Netherlands and internationally. Our motto is "Enabling Delta Life". As an applied research institute,
Deltares is successful if its knowledge is put to good use in and for society. Deltares is very
demanding when it comes to the quality of its knowledge and advice.
