As PhD Candidate within the MELODY project (ModEling LOwer shoreface Seabed DYnamics for a Climate-Proof Coast), I study the possible scale interactions of tidal sand waves on the lower shoreface. This includes the effects of tidal sand waves on the (larger-scale) tidal flow, or the effects of a (larger-scale) seabed topography (for example, the sloping lower shoreface itself) on sand wave characteristics. In the future I aim to combine these two and study the evolution of sand waves on top of a sand bank and how these interact with each other and with the tidal flow.

As part of my PhD, I have studied the extension of the concept of form roughness to a tidal setting, thus induced by tidal sand waves. Currently, I am studying the effects of a sloping bed on sand wave characteristics using a perturbation approach.

In the past I have studied other coastal-related topics. For my Bachelor Thesis I studied the long-term evolution of the Zandmotor mega-nourishment under different sea level rise scenarios. For my Master Thesis I studied barrier island drowning under different sea level rise scenarios using an idealized process-based model.

 

Since October 2023 I am a board member and the secretary of Young-NCK (Netherlands Center for Coastal Research). Since September 2024 I am an elected member of the ET Faculty Council.
