The geothermal energy well at TU Delft campus will soon start heating various buildings on campus and in the city of Delft. But it provides insufficient heat in winter, and excessive heat in summer. Adding underground seasonal storage allows surplus summer heat to be put to good use in winter. Martin Bloemendal and his team develop the means to make integration of such an underground seasonal buffer possible at a large scale.

New findings from a spaceborne monitoring team of University of Houston, TU Delft and DLR indicates the collapse of the Kakhovka Dam in Ukraine may have been already ongoing before the war with Russia, with deformations in the dam pre-dating the actual collapse. The results were published in the journal Nature Communications Earth and Environment this month.

High waves startle mangroves for days during an experiment at the Delta wave flume in Delft. Researchers from Deltares and TU Delft keep increasing the force on the trees. They test how strong the mangrove trees are under extreme wave conditions and what contribution they make to water safety.

In Vietnam, the newly established Mangrove Living Lab has been put into operation. Here, ideas for restoring mangrove forests to protect the Mekong Delta from water are being tested. Today Minister Mark Harbers of Infrastructure and Water Management visited the lab, which is a result of years of cooperation in education and research between TU Delft and Thuy Loi University in Hanoi.

Can salt marshes serve as a natural solution for flood protection? Researchers of the project ‘Living Dikes’ transported 62 big blocks of salt marshes, containing soil and vegetation, from the coast of Friesland to the Delta Flume at Deltares. After four weeks of exposure to extreme waves, almost the entire salt marsh is still standing there.

During the 182nd Dies Natalis of TU Delft, we delved into the theme of "Redesigning Deltas" to underline that we need rethink our approach to keep deltas around the world safe and liveable in the future. As part of the preceding Delta week, we organised a hackathon. On 9 January, students joined forces and took up the challenge: Crafting flood resilience in the Rotterdam region.

A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimetres. The unique dataset provides insights into coastal changes for every hour, for three years. This data is important for dune maintenance and to keep the hinterland well protected. The methodology is also being used to monitor other coastlines and even glaciers. The data are open source and published in Nature, and the new methodology was also recently published.

The HE department had a successful participation at the European Safety and Reliability Association conference ESREL 2023. Leslie Mooyart, Gina Torres, Miguel Mendoza, Guus Rongen, Rieke Santjer, and myself (on behalf of Patricia Mares) presented papers at the conference.

Dimitris Dermentzoglou, PhD student in Coastal Engineering, investigates whether salt marshes can serve as a natural solution for coastal protection. It is why he mimics salt marsh vegetation at the TU Delft Waterlab. He hopes his research will yield a more sustainable alternative to the repeated raising of dikes.

River water is becoming saltier and that is not good news for our drinking water. To find solutions, researchers are working hard to understand when and how salt intrusion happens. Hydraulic engineering PhD candidate Tess Wegman is fascinated by the behaviour of saltwater and freshwater flows taking place beneath the surface of the water.
