The Netherlands has had an indissoluble relationship with water throughout history. Nowadays, 2400 km of waterways flowing through its veins use timber retaining walls along their banks. A more eco-friendly solution than brick or concrete but, still, not as sustainable as it could be. Civil Engineer Abhijith Kamath is researching an alternative method to use tree roots to strengthen waterways’ banks. Making Dutch channels greener in every way.

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.

Intertidal zones are crucial for the protection of our coast and as stop-overs for migrating birds. But, increasingly, many of these sand and mudflats are disappearing permanently underneath the waves. Cynthia Maan investigated how by cooperating with nature and using a systems-based approach these precious resources can be saved.

Playing a bass guitar on top of a dike. It’s not something you see a TU Delft scientist do every day. Yet this is exactly how post-doc Juan Aguilar-López tested his experiment on dike monitoring with the use of fiber optic cables. A technology which could greatly improve dike safety in the future.
