L. Portos - Amill MSc (Laura) | University of Twente

As PhD Candidate within the MELODY project (ModEling LOwer shoreface Seabed DYnamics for a Climate-Proof Coast), I study tidal sand waves on the lower shoreface. In particular, I study how they affect the flow and how they interact with larger-scale topography (sand banks and the sloping lower shoreface itself).

I am currently studying the increased roughness that the tidal flow experiences over a sand wave field. The goal is to come up with parametrizations of the form roughness such that the presence of sand waves can be replaced by an increased roughness, and still yield the same flow pattern at a larger spatial scale.

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).
