    Salinisation risk groundwater around Sea Lock IJmuiden measured

    On behalf of Rijkswaterstaat, Deltares is measuring groundwater quality around the IJmuiden lock complex. For the construction of the Sea Lock and the salt barrier, which carries salt water back to sea, the bottom of the North Sea Canal was deepened. This allows salt seawater to come into contact with fresh or brackish groundwater. Whether this happens and leads to salinisation of the deeper groundwater is monitored by Deltares through a groundwater monitoring network.

    How mangroves can protect coastlines worldwide

    The coming days, mangroves will have a lot to endure during an experiment in our Delta Flume. Researchers from Deltares and TU Delft are gradually increasing the force on the trees. They’re testing how strong the mangrove trees are under extreme wave conditions and how mangroves can help protect coastlines.

    LandSeaLot, observing land-sea interfaces in Europe

    The European LandSeaLot project will establish an observation strategy for European land-sea interfaces, which play a major role in improving biodiversity, CO2 capture and climate resilience. A range of scientific expertises will be combined with stakeholder recommendations, establishing a picture of the potential of land-sea interfaces. Deltares is coordinating this research.

    New coastal elevation model significantly improves on vertical accuracy

    Scientists at Deltares have developed a cutting-edge global coastal Digital Terrain Model (DTM) at 1 arc-second (~30 m) resolution. In our work, we extensively use elevation models as input for our numerical models, but we noticed that current, freely available elevation models are not accurate enough for our purposes. Our experts decided to create a new elevation model, making use of the latest remote sensing data.

    Is the current protection against flowslides good enough?

    In the Netherlands, dikes protect us against floods, and in Italy and other mountainous countries protection barriers can help protect against landslides. The Flowslide Impact Modelling (FIM) project, coordinated by Deltares, tests which barriers work best.

    Opportunities and challenges in offshore solar

    To investigate the environmental impact and sustainability of offshore solar fields, Deltares is participating in the Nautical SUNRISE project. This project examines opportunities and challenges around scaling up and operating offshore floating solar systems. Deltares is looking at what wave power does to a floating solar farm and its effects on marine ecosystems. As a test site, the world's largest offshore floating solar power system will soon be realised on a wind farm 53 kilometres off the Dutch west coast.

    Application for SME facilities challenge Deltares opened

    Deltares is once again opening its doors to innovative initiatives from Dutch start-ups and SMEs. After four successful editions in previous years, Deltares will offer free access to its experimental facilities in 2024. This initiative aims to increase interaction with SMEs.

    Multi-level collaboration key for urban resilience

    Cities are crucial in the fight against climate change, but their efforts must be integrated with those at local, regional, and national levels. A new paper highlights the importance of a multi-level governance approach, the need for collaboration, and regular and sustained dialogue. The paper is a follow-up from COP28 in Dubai.

    Do wood chips help to clean up water in ditches? A range of organisations and government authorities are currently investigating this issue in Westerbeek in the Dutch province of Noord-Brabant. The initial results are positive.

    Already hundreds of wildfires annually in the Netherlands

    The Netherlands has hundreds of wildfires every year. They are often small but the potential consequences are significant. A group of researchers led by Wageningen University & Research, working with wildfire experts from Deltares, the Dutch Fire Department, and the Spanish company Technosylva, has drawn up an overview of the numbers and impact of wildfires in the Netherlands for the first time since 1994, when official registration stopped.

    Further elaboration of long-term sea level rise solutions

    The Sea Level Rise Knowledge Programme, a national research programme of the Ministry of Infrastructure and Water Management and the Delta Commissioner, has had three lines of thought explored for long-term protection against extreme sea level rise: Seaward, Protect and Move with the sea. With all our knowledge, how can we continue our tradition of living and working safely with water in the future and what do we need to take into account now? Deltares contributed to these lines of thought with water system knowledge.

    Foundation damage in the Netherlands mapped out for national approach to foundation problems

    More and more Dutch people are being faced with damage to foundations. Foundations are sensitive to rising and falling land levels, as well as low groundwater levels and therefore dry conditions. Climate change is amplifying the problem. A new analysis by Deltares in collaboration with TNO that was commissioned by the Council for the Environment and Infrastructure (Rli) indicates that, in the short term, there are about 425,000 buildings with an expected technical lifespan of less than fifteen years. Just under a quarter of them are founded on wooden piles; the remaining buildings have shallow foundations.
