Funding for study of the ecological effects of sand extraction in the North Sea
Worldwide, sand reserves are dwindling, while more and more sand is needed to protect coasts against rising sea levels. As part of the National Science Agenda, a study will be launched focusing on the ecological optimisation of sand extraction in the North Sea. To maintain the health of the marine ecosystem and to ensure it can continue to serve as a source of food. Together with about 20 other research applications, this project, in which Deltares is one of the consortium partners, was recently selected as Research along Routes by Consortia (NWA ORC call 2020/2021). -
Global carbon emissions from deforestation reveal surprisingly stable CO2 uptake by land and oceans
Deltares and researchers from other institutions have drawn up a new time series for global carbon emissions from deforestation. The series is the missing link in terms of the improved understanding of the global carbon cycle and it implies that the natural uptake of CO2 by the land and oceans is more efficient than previously assumed. -
The REACHOUT website is now live
REACHOUT is a European Commission funded research and innovation project to advance user-oriented climate services to support the implementation of the Green Deal. Therefore, research partners, climate service providers and city stakeholders are co-developing a coherent set of services for seven city hubs across the EU. 
New IPCC Report: effects of climate change more serious than thought, time is short for effective adaptation
We can still take action now in order to live safely and sustainably in deltas and coastal areas in the future. That is the hopeful message of the new IPCC report (WG2). The urgent call is not limited to the need to reduce carbon emissions; it also focuses on accelerating adaptation to the consequences of climate change. Not all effects of climate change can be prevented and so sound preparation is enormously important.-
Trees excellent at attenuating waves: first scientific evidence now available
A lot of claims are made worldwide about how nature – such as willow trees or mangroves – can help to provide protection against flooding, typhoons and tsunamis. Until now, however, there have been few studies looking at how natural systems behave in extreme conditions like super storms. How well do trees break waves, and can they cope? A paper published this week in Scientific Reports by scientists from Deltares, the Netherlands Institute for Marine Research (NIOZ) and Delft University of Technology, provides the first evidence about how we can best use trees for flood risk management. -
What can COVID-19 teach us about preparing for climate risks in Europe?
High-impact and global crises like the current pandemic reveal our preparedness for disasters. COVID-19 has shown how difficult it can be to effectively respond to severe unprecedented disruptions. As our economies are struggling to adapt to the new normal, researchers are examining how we can learn from this systemic shock to increase societies’ resilience to future pandemics as well as worldwide disruptions, such as the climate crisis. RECEIPT, a H2020 project led by Deltares, is using novel scientific methods to foster preparedness. -
New edition of Deltalife: effects of climate change
Our latest edition of our corporate magazine 'Deltalife' just came out. Climate change is the challenging context for our knowledge, system analyses and the exploration of action perspectives for integrated water management. 
Arcadis requalifies for Delft3D Certified Modelling Centre licence
Arno Nolte, a marine and coastal systems expert, conducted the 2021 recertification audit for the Delft3D Certified Modelling Centre on behalf of Deltares. Implementation was assessed on the basis of the Good Modelling Practice guidelines and two recently completed projects were audited. The components of the audit will be reviewed in brief here.
Seven recommendations in response to the floods of July 2021
What if the extremely heavy rain in July 2021, with devastating consequences in Limburg, Belgium and Germany, had fallen elsewhere in the Netherlands? Deltares researchers studied this question recently in a three-day hackathon. The conclusion is that flooding cannot be prevented when there are such large-scale and extreme precipitation events. Nevertheless, with more resilient spatial planning and better preparation, the Netherlands can stop the disruption turning into a disaster.
Design guideline for aquathermal systems bundles knowledge and experience
To make a better assessment beforehand of important considerations in aquathermal systems, and the risks, experts have developed a design guideline. Aquathermal systems are increasingly being used to heat buildings. They harvest thermal energy from surface water (TEO) and therefore use the water as a sustainable energy source. With the guideline, designers, managers and installation engineers can design reliable and efficient aquathermal systems for now and the long term.
High water in Limburg in the summer of 2021 had more impact than river floods in 1993 and 1995
The intense rainfall and high water of July 2021 in the Netherlands and the neighbouring countries was an extreme and exceptional event with a major social impact in Limburg. On behalf of the Expertise Network on Flood Risk Management (ENW), a broad consortium of research institutions led by Delft University of Technology and Deltares has now completed an initial analysis of the available information on a range of subjects.
Nature-based Solutions as cost-effective method to drive climate change adaptation
With Germany, Belgium and Turkey still reeling from historic floods, a new report outlines how Nature-based Solutions can help reduce the impact of such disasters across Europe.
