Hoe voorspel je de ontwikkeling van de Rijn als de afvoer historisch laag is? Op 8 augustus sneuvelde het lage-afvoerrecord uit 1947. Nog nooit stroomde er zo vroeg in het jaar zo weinig water door de Rijn.    Dat heeft directe gevolgen. Binnenvaartschepen moeten vracht achterlaten, sproeiverboden worden ingesteld en sluizen worden gesloten om water vast te houden. Tegelijkertijd willen waterbeheerders weten: hoe ontwikkelt de situatie zich de komende weken?   Jan Verkade, hydrometeoroloog bij Deltares en lid van de crisisadviesgroep Rivieren van het Watermanagementcentrum Nederland (WMCN) van Rijkswaterstaat, kijkt samen met collega’s vooruit. Met meetgegevens, weersverwachtingen en modelberekeningen proberen zij de ontwikkeling van de Rijn en Maas zo goed mogelijk in beeld te brengen.   Juist nu is dat extra uitdagend. De huidige omstandigheden zijn uitzonderlijk en historische voorbeelden zijn schaars.   🗨️ “We leren bij over hoe de hydrologie met het klimaat verandert. Het is niet alleen een verandering in getallen, maar ook in mechanismen", aldus Jan.   Elke extreme situatie levert nieuwe kennis op. Over hoe rivieren reageren op droogte, hoe modellen presteren en welke veranderingen het klimaat met zich meebrengt.   Lees het hele verhaal over voorspellen, onzekerheid en wat deze uitzonderlijke droogte ons leert 👉 https://lnkd.in/eyWmqzve   Karst Oosterhuis #Rijn #Laagwater #Droogte #EnablingDeltaLife

👣 What's going on beneath our feet? On our campus in Delft, we're using innovative monitoring techniques to map the behaviour of an aquifer: a groundwater-bearing layer of sand, gravel or rock. This aquifer is part of the Aquifer Thermal Energy Storage (ATES) system that provides sustainable heating and cooling for several Deltares buildings. In summer, cold groundwater is used to cool buildings, while in winter the process is reversed to provide heating.   To better understand how the system performs over time, Deltares experts in applied geology and geophysics are monitoring what happens underground. This helps us maintain and optimise the ATES system more effectively.   🗨️ Applied geophysics expert Roeland Nieboer has been involved from the start: "Long fibre-optic cables make it possible to continuously monitor conditions throughout the aquifer, enabling rapid detection of changes. Improved insight into groundwater flow will help prevent clogging of the wells and contribute to more efficient operation of the system."   A key advantage of fibre-optic monitoring is that temperature can be measured continuously along the entire aquifer without disrupting the operation of the ATES system.   The project not only supports more sustainable operations on the Deltares campus, but also expands our knowledge of the subsurface. The insights gained can help improve the design and management of future subsurface energy storage systems. 🔗 Dig deeper underground on our website > https://lnkd.in/dRN8JU6A #EnablingDeltaLife #ATES #aquifer

Om klimaatverandering te beperken, is vermindering van broeikasgasuitstoot noodzakelijk. Hoe weet je of maatregelen voor broeikasgasreductie daadwerkelijk effect hebben? Dat begint met betrouwbaar meten. Want alleen als we emissies goed in beeld hebben, kunnen we effectieve keuzes maken voor klimaatneutraal water- en bodembeheer ter ondersteuning van de energietransitie. 🔬 Deltares brengt de emissie uit water- en bodemsystemen in kaart en ontwikkelt kennis en instrumenten, in samenwerking met allerlei partners. We combineren expertise op het gebied van emissiereductie met eigen onderzoeksfaciliteiten, waarmee we emissies onder gecontroleerde en realistische omstandigheden kunnen onderzoeken. Met meetmethoden en data ondersteunen we overheden, waterbeheerders en ontwerpers door: ✅ Inzicht te geven in waar en waardoor emissies ontstaan; ✅ Het effect van beheermaatregelen te kwantificeren; ✅ Kennis te vertalen naar beleidsinstrumenten, emissieregistraties en ontwerpprincipes. Door beter te meten, kunnen we gerichter handelen en sneller impact maken op weg naar een klimaatneutrale toekomst. 🔗 Meer informatie op onze website > https://lnkd.in/eaxz4neX #EnablingDeltaLife #Broeikasgasreductie #Energietransitie

⚡BioBlitz⚡ Marker Wadden! Last week nearly 100 enthusiastic volunteers helped record the biodiversity of the Marker Wadden!   During a BioBlitz participants try to identify as many wild species as they can in a set time and within a defined area. Among other things, we found: 🌱 90 plant species 🐦 62 bird species 🪲 23 beetle species 🐛 20 species of bugs, cicadas and aphids 🐚 12 species of molluscs “It was great to see that the participants themselves also had specialist knowledge of species and were keen to share that knowledge with us.," says Lilith Kramer, Aquatic ecologist freshwater at Deltares. With the help of our experts, no fewer than 1,240 observations were made and 256 different species recorded. You can also use apps to identify species you're not yet familiar with.   Participants were also given an explanation of how the Marker Wadden came into being and the role the islands play in nature restoration. 🔎 Our sightings also gave a boost to Nieuw Land National Park’s ‘Year of Species 2026’.   Thanks to all the participants, experts and partners who made this successful BioBlitz possible! #EnablingDeltaLife #FieldworkFriday Natuurmonumenten Wageningen Marine Research FutureLakes

Tanzania’s Pangani Basin is a vital water source that serves communities, agriculture, industry, energy production, and ecosystems, but how can it remain resilient in a changing climate? Our experts Henrique Goulart and Sadie McEvoy were in Tanzania this month to work with local stakeholders and assess climate vulnerabilities and identify adaptation pathways for the basin. The Government of Tanzania, supported by UNESCO, is conducting a climate risk analysis and identifying climate adaptation actions in the Pangani Basin. This analysis will inform the design and implementation of Tanzania’s National Adaptation Plan, with a particular focus on water-related planning in the Pangani Basin. The Climate Risk Informed Decision Analysis (CRIDA) framework was applied to assess climate vulnerabilities and identify adaptation measures. Using Deltares models wflow and Ribasim, the team simulated the river system under different climate change scenarios. These insights, combined with the CRIDA framework, help evaluate the vulnerability of water resources in the Pangani Basin and support the development of robust and flexible adaptation strategies. 🙏 Thanks to local partners and stakeholders who participated! Your feedback and the data we exchanged are invaluable for calibrating models and shaping realistic adaptation options. Our researchers are now incorporating this feedback into the models to improve them, and a report to support further activities will follow later. #EnablingDeltaLife #Tanzania #ClimateResilience

🐟 Fintastic news! During a fish survey on our campus in Delft, 8 volunteers of the Fish Team from Natuurvereniging KNNV Natuurlijk Delfland, counted 10 different fish species. Including: 19 roach, 4 silver bream, 4 Caucasian dwarf goby, 1 Western tubenose goby, 27 spined loach, 12 rudd, 1 pike, 5 tench, and even a small three-spined stickleback. The researchers used special nets to temporarily catch the fish, identify them, and then carefully release them back into the water. 🗨️ Tom Buijse, specialist in freshwater ecosystem health and restorationon at Deltares:  “Fish species such as roach, pike, tench and rudd are indicative of a clear and plant-rich ecosystem. Of particular note was the spined loach, which is a protected species in Europe; however, exotic gobies have also somehow managed to find their way into the water courses. We much appreciate that they carried out this research on our campus.”   KNNV Natuurlijk Delfland intends to carry out another survey next year, so that the development of the fish population on our site can be monitored further. #EnablingDeltaLife #FishSurvey #biodiversity

🔎 How can offshore cables and pipelines be decommissioned more efficiently? The Frequensea Decommissioning Tool has been developed to address this challenge and is currently being tested at Deltares.   The tool uses vibration-induced fluidisation to loosen the surrounding soil and reduce the pulling force required to recover offshore pipes and cables. At our facilities, the Frequensea team is carrying out full-scale tests under controlled and realistic soil conditions.   👀 Recently, partners and sponsors joined us for a live demonstration of the technology. The event provided an opportunity to see the tool in operation, discuss the initial observations, and look ahead to the next stages of the testing and qualification programme.   Testing technologies at full scale is an important step in moving from an innovative concept towards reliable offshore application. We are pleased to contribute our facilities and expertise to this development.   🎥 Watch the video for a glimpse of the Frequensea Decommissioning Tool being tested at Deltares.   Interested in learning more about the project? Get in touch with Astha Sharma, Cihan Cengiz, Guido Remmerswaal or Marcel Busink.   The demonstration was attended by representatives from Frequensea, DEME Group and Subsea Cable Assets (SCA). The project is supported by the Topsector Energie / Energy Innovation NL programme through a subsidy from the Netherlands Enterprise Agency, Rijksdienst voor Ondernemend Nederland (RVO).   #OffshoreDecommissioning #SubseaEngineering #PipelineRemoval #EnablingDeltaLife
