NUSDeltares is a non-profit knowledge alliance between the National University of Singapore (NUS) and Deltares, an independent institute for applied research in the field of water and subsurface from the Netherlands. NUSDeltares leverages skills of approximately 2,000 specialists from various research groups within NUS and 800 specialists from Deltares to work together and provide high impact contract research and specialized consultancy services on water and subsurface-related issues in Singapore, Asia and beyond.


What we do: primary topics and more
NUS and Deltares focus their strategic cooperation on three societal challenges:
1. Adaptation to Climate Change
2. High Density Living
3. Urban Water Management

The knowledge cycle

Within the Alliance, NUS and Deltares cooperate on the basis of their complementary position in the knowledge cycle. In this cycle, mono-disciplinary research results are combined and integrated to generate cross-disciplinary innovative solutions for societal questions, and societal questions are differentiated back into mono-disciplinary fundamental research questions. NUS is mainly focused on fundamental research, whereas Deltares acts more on the applied side.
Jointly, we cover the complete cycle, and realize both scientific and societal impact.

Bridging science and society requires integration across at least two dimensions:
• across disciplines, since societal challenges require holistic approaches
• across knowledge stages, since results from fundamental research must be made applicable, disseminated, and applied in order to have societal impact.

The structure of the Alliance
The participating research groups form the core of the Alliance. They cooperate in the open network structure that the Alliance offers, and work in flexible partnerships as needed for the issues at hand. The Office of NUSDeltares facilitates the functioning of the Alliance. The Office helps in identifying stakeholder needs, acts as a knowledge broker, connects the research groups, and enables the knowledge cycle to work. Our Governing Board warrants high-level support for the alliance ensuring a smooth cooperation between the parent organizations NUS and Deltares. Data, models and information systems Data, models and expert knowledge are important sources of information about the actual and expected state of water- and soil systems. In our integrated information platforms we combine them, using concepts from data science and hydro-informatics. This results in the best possible information, at the relevant spatial and time scales and at the desired aggregation levels.

Our advanced data-, model- and information systems all are developed and maintained according to best software practices. These software tools are not only essential for our work, but are also important vehicles through which we share our knowledge and technology. Our open-source policy enables a large community to use and/or further develop these tools.

In our research, field and laboratory experiments are indispensable to improve our understanding of processes and to obtain validation data. In specialist consultancy, we use experimental facilities to investigate phenomena in case numerical models are not yet capable to describe them with sufficient accuracy. Jointly, NUS and Deltares have unique laboratories and facilities.
