This year’s Grote Maaskantprijs is awarded to the collective of scientists, governments, companies and civil society organisations behind project NL2120. Deltares is one of the partners in this project. According to the jury, NL2120 offers 'an inspiring perspective on the climate-adaptive, nature-inclusive and CO2-neutral spatial planning of the Netherlands'.

Ageing infrastructure is increasingly in the news. Maintenance work on our grey and green infrastructure is essential to prevent disruption and damage. In the book ‘Asset Management of Urban Drainage Systems’, a number of authors, including experts from Deltares, discuss the latest technologies. There are also chapters looking at legislation and standards, the use of data and decision-making.

The Aquality App (formerly Nitrate App) has added many new features since our collaboration with IBM. We launched the latest update for the App that makes it possible to add measured phosphate and ammonium concentrations and manage groups for sharing measurement results.

A team of international researchers is investigating the potential for the world's low-lying coral atoll islands to withstand predicted sea level rises through natural flooding processes. Last month, Deltares experts Robert McCall and Floortje Roelvink joined the international research team for fieldwork in the Maldives. They collected data to support predictions of how these islands might respond to future sea level changes.

The first edition of the IPDC report was launched today during the 10th World Water Forum in Bali, Indonesia. Introducing the IPDC Guidance Framework for member countries and setting out the challenges faced by deltas, coasts, and islands. The report also provides a solid base for the IPDC’s future activities.

Today Deltares presented the new Delta Scenarios to Minister Mark Harbers (Infrastructure and Water Management) and Delta Commissioner Co Verdaas. Four scenarios show what we need to take into consideration in policy for water and spatial planning until the end of this century. In all four, the agendas relating to water will become a lot more challenging: freshwater shortages in summer will increase, there will be more problems with excess water caused by rainfall, and floods will have more impact. Bottlenecks relating to water shortages, problems with excess water and flood risk management are stacking up. That will affect all of the Netherlands.

How do we exploit the opportunities of soils in our spatial planning? The European project SPADES (Spatial Planning And DEsign with Soil) focuses on securing soils in spatial developments, as part of the Mission A Soil Deal for Europe. Researchers are tackling this question in seventeen locations in Europe, including two in the Netherlands. Deltares is coordinating this project together with TU Delft.

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.

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.

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.

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.

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.
