A new comprehensive international guidance document for implementing source-to-sea water management in transboundary basins has been published by UNECE (United Nations Economic Commission for Europe). Compiled by an international group of experts, Deltares contributed several case studies to the document.

How can the natural water storage capacity of landscapes be restored? This ‘sponge function’ of the landscape is important for storing surplus rain water, replenishing groundwater reserves and protecting biodiversity. The European Union is investigating how to achieve this goal in the Horizon Europe programme. Deltares is involved in two of the three research projects: SpongeScapes and SpongeWorks

Deltares has published the Activity Plan Mission-driven research 2026 in draft. It outlines the main lines of the Strategic Research that Deltares will carry out in 2026.

Niagara Falls is not only a world-famous natural phenomenon but also a powerful source of renewable energy. The hydroelectric power plants supply electricity to around 100,000 households. But how do you align energy production with fluctuating demand and international agreements? Ontario Power Generation (OPG) asked Deltares USA for help, who requested the support of Stichting Deltares.

Climate change is causing increasingly frequent extreme weather events and, as a result, potential flooding. The damage is often not only local: businesses and economic chains can also be disrupted. This makes recovery after a disaster particularly difficult. At the same time, it is difficult to predict exactly how the climate and society will develop. It is therefore important for regional administrators to make smart choices: where are the risks greatest, and where can resources best be deployed?

Saba wants to take targeted measures to protect its unique marine environment. To do so, there is also a need to understand how pollution occurs via groundwater. A new study by Deltares, commissioned by the Public Entity of Saba, provides the first complete picture of how nutrients, such as nitrogen and phosphorus, end up in the sea from land, and what role groundwater plays in this.

This year the Netherlands and Singapore mark a major milestone; 60 years of bilateral ties. These ties span across a range of topics, including water management, climate adaptation, and sustainable development. Deltares is proud to be part of this cooperation.

To keep the Dutch delta liveable and safe, adjustments are needed to a changing climate. But how do we ensure that today's investments contribute to a future-proof Netherlands? Together with Rijkswaterstaat and the Delta Programme Commissioner, Deltares has developed a new method for this: DAPP-Δ, which helps policymakers understand which choices are decisive for the future.

Deltares, Wageningen University, VU Amsterdam, and the World Bank have developed a new governance framework supporting countries to manage floods and droughts synergistically. The results of this effort has recently been published in PLOS Water.

What happens when there is a power cut in a major city or extreme weather make roads impassable? Deltares conducted a study for the city of Amsterdam to investigate the cascade effects of the loss of critical infrastructure due to climate threats such as flooding, heat and drought. Interdependencies and possible cascade effects were identified in collaboration with providers of vital functions.

The Marker Wadden, a man-made archipelago in the Markermeer lake, was constructed with local sediment and designed to restore ecological functions and open up leisure activities. The project is one of a kind, not only because of the innovative design but particularly because of how the financing was arranged.

Where are fresh and saline groundwater located and at what depth? And where are the clay layers that protect the underlying groundwater? This is important information for provincial authorities, water managers, water authorities, farmers and nature managers. To establish a picture, measurements will be made with a helicopter from August this year until February next year in the southern, western and northern Netherlands.
