    Water infrastructure future-proof replacement and renovation

    How do we future proof our locks, dams, pumping stations and barriers? In the upcoming replacement or renovation task of wet engineering structures, we take into account the new climate scenarios from KNMI. Together with Rijkswaterstaat, Deltares is working on a set of starting points in the EUO-Kunst project, with the Oostsluis in Weurt as a pilot. This national monument is due for replacement and the more frequent low water levels of the river Waal will determine the threshold height of its successor.

    From shoreface to dunes: integrated coastal modelling

    Rising sea levels and increasing human activity is causing the pressure on coasts around the world to increase. Sandy solutions can safeguard water safety, recreation, and nature. The success of these natural solutions depends on their dynamic development, driven by water, wind, vegetation, and humans. An innovation in modelling now makes it possible to make even better predictions of the integral consequences of coastal solutions; from foreshore to dune. This was investigated by Deltares researcher Bart van Westen, together with other scientists.

    Deltaflume tests world's longest self-closing flood barrier

    This week, Deltares' Deltaflume carried out wave tests to investigate the strength of a self-closing flood barrier that will be built along the renewed Scheldt quays in Antwerp. The self-closing flood barrier is hidden underground and rises only in cases of high water levels. The tests went well, which means that the concept of the self-closing dam is ready to protect Antwerp from flooding caused by storm tides on the Scheldt.

    Understanding the influence of climate change on weather extremes and their societal impact

    Attribution of the effect of global warming on (compound) weather extremes and their impacts is a key challenge in climate research. Within the new European project 'Compound extremes attribution of climate change: towards an operational service' (COMPASS), led by Deltares, a framework will be developed for climate and impact attribution of compound extremes.

    What is the most suitable and cost-effective scour protection method for each situation? An overview of measures can now be found in the Handbook of Scour and Cable Protection Methods. This manual is the result of the multi-year research programme Joint Industry Project HaSPro, in which more than 20 companies worked together, initated and coordinated by Deltares.

    How will our health change in the future? Creating knowledge-based scenarios

    Our world is changing in terms of both climate and socio-economics. These changes could have a profound impact on the health of humans, animals and the environment, which in combination is often referred to as ‘One Health’. The recent paper ‘Creating the Dutch One Health Shared Socio-economic Pathways (SSPs)’ helps us to see where and when we should intervene.

    Cause of Juliana Canal construction pit failure determined

    Rijkswaterstaat commissioned Deltares to investigate the cause of the failure of the construction pit on the Juliana Canal between Berg and Obbicht. The construction pit flooded in February 2023, two months after work began. It was determined that a combination of circumstances eventually led to underflow of the sheet piling (a flow of water through and / or under the sheet piling). Within seven minutes, the construction pit flooded with water from the canal.

    The first high-resolution, time-dependent groundwater model of the world

    Groundwater scientists and model developers from Utrecht University and Deltares have teamed up to make the first-ever, one-kilometre, groundwater model with global coverage. This is an important step on the road to establishing a better picture of groundwater in global water and climate models.

    Looking back at the high-water peak during the 2023-2024 Christmas break

    High water gripped the Netherlands during the 2023-2024 festive season. The Maeslant barrier closed for 24 hours because of the high sea levels due to storm Pia. For the second time in history, the five main Dutch flood barriers closed at the same time. Heavy rainfall, supplemented by meltwater, then caused discharge levels to peak in major rivers such as the Rhine. The Waal, Nederrijn-Lek and IJssel, and the Meuse were high, as were smaller rivers such as the Vecht, Regge and Dinkel. And water levels in the IJsselmeer and Markermeer lakes reached record highs. We look back and think about the future: what are the implications for future research?

    Five questions about the impact of floods on the financial sector

    Extremere waterstanden komen steeds vaker voor in ons land. Wat zijn de effecten van overstromingsrisico’s op de financiële sector? Deltares onderzocht dit samen met De Nederlandse Bank (DNB).

    Working together to strengthen coastal resilience

    Coastal areas are vital ecosystems that are home to 40 percent of the world's population and host biodiversity hotspots crucial for carbon sequestration. Despite their great importance, a comprehensive understanding of these areas was lacking until recently.

    Dynamics muddy coasts mapped for the first time

    Where muddy beaches are located and how they change has been visualised for the first time worldwide using satellite imagery, machine learning and various coastal datasets. This shows that three quarters of the world's muddy coasts have changed significantly since 1988. A study by Deltares, TU Delft, KU Leuven, and Shanghai's East China Normal University, allows local insights and flood control solutions to be scaled up to other places in the world. The research has been published in Nature.
