Stefan is professor of Coastal Engineering at Delft University of Technology, in the Netherlands and Chair of the Department of Hydraulic Engineering. He holds a PhD from Delft University of Technology and previously worked for Delft Hydraulics (now Deltares) and Boskalis. His research interests include monitoring/ modelling of nearshore coastal processes, dredging for marine infrastructure and Building with Nature, ultimately to enable broad implementation of nature-based solutions in daily engineering and management practice.

The use of nature and natural processes is an innovative way to increase water safety and create added value through nature development and recreation. This exploratory study provides an initial inventory of the impact and costs of existing Building with Nature projects in the Netherlands. It also includes an analysis of the decision-making process in choosing this type of project and identifies success factors. Building with Nature projects deliver added value but often also involve additional costs compared to traditional reinforcements. These costs give an indication of what we as a society are prepared to pay for the development of nature and recreation as part of hydraulic engineering projects.
Rather than focus on minimising negative effects, ecologically designed sand mining can maximise positive opportunities to dredge and create new habitats.
Validation of the Tass System for Predicting the Environmental Effects of Trailing Suction Hopper Dredgers
Models created by researchers using innovative software have been tested and validated by monitoring trailers during dredging operations.
A state-of-the-art 3D plume model, used at the Ras Laffan Port Expansion project, simulates alternative disposal scenarios and helps develop Safe Disposal Maps.
To assess the environmental benefits of an “idyllic” world without dredging, the impacts of dredging activities are compared to the impacts of other human and natural sources of sediment plumes.
