How much higher do waves get as sea level rises?

(26-11-2021) Panagiotis Vasarmidis improves wave propagation models in his doctoral research so that wave heights can be better predicted with sea-level rise.

One of the challenges that the engineering world has to face is the study of coastal environments, in order to assess their vulnerability due to the rising of the sea-level and the resulting increase of the wave heights.

Towards this goal, numerical models constitute a valuable tool for coastal engineers. In recent years, phase-resolving wave models are used more and more often in order to get a realistic and accurate representation of the waves in the field and their transformation over time and space.

"In my research I have been looking for new methods to improve wave propagation models," says Panagiotis Vasarmidis

"More specifically, we performed developments in two phase-resolving models, the linear wave model MILDwave and the non-linear wave model SWASH."

“The main goal was to improve the homogeneity of the generated wave fields in these wave models. We achieved this by enhancing their capability of accurately generating the target wave conditions and at the same time by minimising any disturbance caused by the imposed numerical boundaries," explains Panagiotis.

"Thanks to my research, we can now make a better estimation of the new wave conditions that follow from the climate change and we will hopefully be better prepared," Panagiotis concludes.

Panagiotis Vasarmidis

Panagiotis Vasarmidis (°Patras, Greece, 1990) obtained his first master degree in Civil Engineering by the University of Patras (Greece) in 2013 with specialization in Hydraulic and Geotechnical Engineering. Then, he was admitted in the master program in Civil Engineering of the Technical University of Delft (The Netherlands), track Hydraulic Engineering, with specialization in Coastal Engineering, from where he obtained his second Master of Science in Civil Engineering in 2016.

Subsequently, Panagiotis decided to follow his increased research interests and started to pursue a PhD at the Department of Civil Engineering at Ghent University where he focused on extending the capabilities and improving the accuracy of phase resolving wave propagation models.

In 2017, he was awarded a PhD fellowship by Research Foundation - Flanders (FWO). As a project engineer, he worked in various coastal engineering projects involving numerical wave modeling and experimental model tests.

Panagiotis coauthored more than 10 publications, including 3 international journal papers as first author. Besides his research activities, he supervised 9 master students and worked as a teaching assistant for the courses "Coastal engineering" and "Coastal hydrodynamics".
