Professor Stefan Aarninkhof is the new Department Chair of Hydraulic Engineering as of 1 March 2020. He takes over the activities of professor Wim Uijttewaal, who has led the department for four years.

PhD candidate Lodewijk de Vet stood in the mud for weeks, in order to learn about organisms in the seabed and to take measurements. He wants to understand the Eastern and Western Scheldt better, so that he can help the ecology while simultaneously protecting our country from rising sea levels. His understanding of these areas served as a foundation for the Roggenplaat nourishments, that have since been executed.

Waking up early and going into the field on a small fishermen's boat, while the sun is rising behind volcano tops. That's how days started for PhD student Silke Tas during her two month fieldwork in Indonesia. The rest of her days were less idyllic: they consisted mostly of treading through the mud to get the right measurements for her research. She studies the workings of coastal sandbanks that give a chance to mangrove forests to restore, so that the forests can, in turn, prevent coast erosion.

For months hydraulic engineer Patrick Oosterlo has been waiting for a heavy storm. One that can truly test his equipment that was installed in and on a dike on the coast of the eastern Wadden Sea. He needs high waves and strong winds to decide: is this dike high enough?

Rivers take vital water to villages and cities, but unfortunately they also carry harmful plastic to oceans. In order to prevent this, we need to find out exactly where the plastic comes from and how it is distributed over time and space. Counting plastic waste items from bridges is one of the commonly used methods to do this. But then how can the huge amounts of plastic in inaccessible places be pinpointed? Master student in Hydraulic Engineering Marlein Geraeds spent her internship at The Ocean Cleanup investigating how to monitor plastic waste in Malaysia’s River Klang by means of drones.

When looking at a dike, you wouldn’t be able to detect any motion in this robust structure. Though in fact there is. On a millimetre level, dikes expand and shrink in relation to the weather conditions. Ece Özer showed that observing this ‘breathing’ of dikes could help prevent catastrophic flooding events. She used this feature to create an innovative model based on satellite data to better detect weaknesses in a dike.

At the weekend Matthieu de Schipper likes to surf the waves but on weekdays he studies how they transport the sand along the coast and up and down beaches. ‘Sea level rise is a threat to coasts across the globe. I want to use the forces of nature to provide engineering solutions to this problem on a global scale’. At the Sand Motor project in the Netherlands De Schipper is training students to do the necessary fieldwork. In all weathers.
