Anniversary symposium 'Managing with water and soil'
Deltares celebrates 15 years! A special milestone that we celebrated with an anniversary symposium 'Managing with water and soil'. Three experts from Deltares, Marta Faneca, Thomas Bles and Ruben Dahm, told their inspiring stories about how densely populated deltas can remain liveable, sustainable and safe. “Look through the eyes of our children to clarify the plans for future water and soil management,” is the conclusion of the panel discussion with figureheads from the water and soil sector.Smart use of sand to extend protection against sea level rise
The possibility of a much faster rise in sea levels poses major challenges for the Netherlands. An adaptive and flexible response to future sea level rise is an innovative way to prepare for that uncertain future. One way to go about this is coastal maintenance in the form of sand nourishments. Two recent studies by Deltares and partners, one of them commissioned by the Ministry of Infrastructure and Water Management as part of the Sea Level Rise Knowledge Programme, demonstrate that there are many options available for sandy coastal management, on condition that enough sufficient sand reserves continue to be readily available.-
Nature Based Solutions for climate resiliency in Europe’s Atlantic region
A consortium of 30 partners (in Denmark, Netherlands, Belgium, France, Spain, Portugal, Italy) will soon kick-off the project ‘Nature Based Solutions for Atlantic Regional Climate Resilience’, a Horizon Europe call, funded by the EC under contract 101112836. The consortium is led by Deltares. Smarter protection of quay walls through better understanding of propeller jets
Port and waterway authorities usually protect their infrastructure, such as quays and berths at locks, from erosion caused by ship propellers by installing bed protection. Recent research is improving the way the behaviour of currents caused by ship propellers during mooring and berthing is mapped with new measurement techniques and advanced calculations. The outcomes provide valuable knowledge for infrastructure managers. By designing bed protection smarter, managers can save on costs, materials and emissions. In this research, knowledge institutes Deltares and MARIN are working together with port companies, the Dutch Directorate-General for Public Works and Water Management (Rijkswaterstaat) and contractors.Land Subsidence and Foundations Knowledge Centre officially opened
The Land Subsidence and Foundations Knowledge Centre was officially opened today at the Tenth International Symposium on Land Subsidence (TISOLS). TISOLS is an international scientific congress about land subsidence. The Netherlands is hosting the symposium again after almost thirty years. Land subsidence experts from throughout the world gathered for a week to discuss the latest insights and methods in the domain of land subsidence. The final day was in Gouda and it was devoted to bringing science and policy together.IPCC data on coastal flood risk on BlueEarth
The recent IPCC report states that sea level rise poses a distinctive and severe adaptation challenge. It implies dealing with slow onset changes and increased frequency and magnitude of extreme sea level events, which will escalate in the coming decades. Such adaptation challenges would occur much earlier under high rates of sea level rise. Data on the projected population at risk to coastal flooding is now available on Deltares’ BlueEarth Data platform, a web-based application supporting the study and sharing of integrated water and subsoil-related data.-
Sea level rise on the Dutch coast has increased
In collaboration with the Royal Netherlands Meteorological Institute (KNMI), Deltares today presented the four-yearly report about the observed sea level on the Dutch Coast. Improved techniques for analysis were used to determine the effect of wind on sea level more accurately. The conclusions about sea level rise are therefore more robust. The most striking result is that the increase of sea level rise can now also be seen on the Dutch coast. IPDC officially launched at UN 2023 Water Conference
The International Panel on Deltas, Coastal Areas and Islands (IPDC) was officially launched at the UN 2023 Water Conference. The IPDC is a unique partnership, bringing together governments, financial institutions, scientific experts, and practitioners from around the world. During the event, ministers and high-level representatives from 12 countries and international financial institutions expressed their support for the IPDC and stressed the need to take climate adaptation action. The IPDC is a Dutch government-led initiative, and is supported by Deltares, the Global Center on Adaptation, and the Delta Alliance.Flood risk ten times higher in many places over the world within 30 years
After the North Sea Flood of 1953, it took nearly 45 years to finalise the Delta Works. If we want to protect the Netherlands against sea-level rise, we shouldn’t wait too long. But how much time do we have left? Researchers from Utrecht University, Deltares, and NIOZ, among others, devised a new method to calculate when we can expect a certain increase in flood probability in a specific area. The calculations show that within thirty years, the estimated probability of flooding will be ten times higher in more than a quarter of the places studied. The researchers publish their results today in Nature Climate Change.IPCC: measures are available for necessary and urgent climate action
The Synthesis Report of the Intergovernmental Panel on Climate Change (IPCC) was presented today. The report marks the end of the sixth assessment cycle and integrates the special reports (such as SROCC) and the reports of Working Group 1 on climate change, Working Group 2 on climate impacts and adaptation, and Working Group 3 on climate mitigation.-
New flagship report for the High-level Experts and Leaders Panel on Water and Disasters (HELP)
Deltares has published a new flagship report for the High-level Experts and Leaders Panel on Water and Disasters (HELP), entitled: Addressing Water-Related Disasters in an Era of Multiple Crises: Lessons from Global Responses to COVID and Climate Change. New edition of Deltalife: How water affects the future
A new edition of our online magazine Deltalife just came out. It is incredible that billions of people around the world have lacked access to clean and safe drinking water or sanitation for so long. At the UN conference in New York next week, this will be addressed. We interviewed Nathalie Olijslager, the Program Director on behalf of the Dutch government, about this.
