NieuweWarmteNu! to build collective heating systems thanks to Growth Fund
With the help of 200 million euros from the National Growth Fund, NieuweWarmteNu! (NewHeatNow!) can phase out the use of natural gas by 26,000 homes and buildings, and over 800 acres of greenhouses. The Minister of Economic Affairs and Climate has decided to follow the recommendation of the Growth Fund committee and to invest in collective sustainable heating systems with all the members of the NWN! consortium. Deltares is one of those members and it co-wrote the proposal to accelerate the heating transition. 
Drought key issue for Deltares at SIWI World Water Week 2022
Deltares experts will attend the SIWI World Water Week 2022, hosting and contributing to sessions both online and in person. Drought will be a key issue for many of the sessions, which will look at how to tackle the issue from a range of different angles, including societal and governmental, geographical, resilience, and using nature-based solutions.-
Communities around small reservoirs more vulnerable to climate extremes
The water volume in small reservoirs is significantly more susceptible to seasonal and climate variability than larger reservoirs, leaving communities that rely on them more vulnerable to water scarcity and food insecurity, according to new research. -
Louisiana Governor visits the Netherlands to exchange lessons on flood risk management
This week Louisiana governor John Bel Edwards led a delegation of business and state leaders on an economic development, water management and resiliency mission to the Netherlands. The delegation visited Deltares and several flood risk management projects. 
Capturing plastic effectively by looking at the water column as a whole
The European project Maelstrom is looking for hot spots with plastic pollution. The objective is to remove as much plastic as possible from the water, recycle it and reuse it. Deltares is involved in research looking at the possibilities in an estuary in Northern Portugal. But before you start ‘fishing’, it’s a good idea to know where there is most plastic in the water-
New global projections of tides and storm surge available based on high resolution climate models
In the coming decades, the frequency of coastal flooding will increase due to sea-level rise and changes in climate extremes, putting the millions of people living in low-lying areas at risk. The increased flooding frequency will be driven by sea-level rise, but changes in storms that generate hazardous storm surges may contribute. To inform climate mitigation and adaptation efforts, there is a need for accurate information on extreme sea levels and how they change under global warming. -
New study shows flood risk already affects 1.81 billion people
In many places of the world, flooding is expected to increase in both frequency and intensity, jeopardizing development agendas of many countries. Researchers from the World Bank, Deltares and UCL found in a new study that almost one fourth of the world population (1.81 billion people) live in locations that are exposed to at least 0.15 meters of inundation depth in a 1-in-100-year flood event. The results of their study were published in Nature Communications this week. 
Reducing the ecosystem-based carbon footprint of coastal engineering
Greenhouse gas emissions from coastal engineering do not only involve emissions from (dredging) vessels, but also from impacting sediments and coastal ecosystems. A new report by Wetlands International, developed with Witteveen+Bos and Deltares, outlines a simplified methodology for quantifying the ecosystem-based carbon footprint of coastal engineering projects. We also present potential options to reduce the carbon footprint, including through Nature-based Solutions.-
Meet the Scientific Council of Deltares
The Science Council promotes excellence and strengthens the science authority of Deltares, by reinforcing the knowledge base, by inspiring the Deltares community of researchers, by detecting and anticipating game-changers, and by stimulating sound scientific practices and products, thereby making Deltares fit for the future. -
The Netherlands has a new research facility with an advanced time machine for soil processes
Today, the unique GeoCentrifuge, a new research facility of knowledge institute Deltares, is opened. With the GeoCentrifuge, soil processes can be tested to scale by increasing gravity. What would normally take years in the ground can now be reduced to mere hours. Given the societal challenges caused by climate change, subsidence and pressure on space, this innovative research facility is vital for a resilient and sustainable infrastructure. -
Research on future-proof bridges and quays awarded by National Research Agenda
Within the Dutch National Research Agenda (NWA) 'Bridges and Quay Walls in Urban Areas' one of the research projects has been awarded to associate professor Mandy Korff (Deltares / TU Delft Civil Engineering and Geosciences (CEG)). 
New study of the relationship between climate change and socio-economic tipping points
Climate change can cause sudden socio-economic tipping points, such as large-scale bankruptcies of low-lying ski resorts, the collapse of house prices due to sea level rise, or the extensive disruption of the road network due to flooding. Kees van Ginkel (Deltares) spent four years researching tipping points of this kind. He will present the results, which have been published in various journals, at a scientific conference in Vienna (EGU) this week.
