Virtual Guest Lecture at Geophysics Department Hasanuddin University: Insights into Shallow Flow Modelling by Prof. Sangyoung Son

On October 17, 2024, from 2 to 4 p.m., the Department of Geophysics at the Faculty of Mathematics and Natural Sciences, Universitas Hasanuddin, successfully hosted a virtual guest lecture. The event featured Prof. Sangyoung Son from the Coastal Hydrodynamics Laboratory, Korea University, as the guest speaker. His lecture, titled “Shallow Flow Modelling Based on Perturbation Theory: Past, Present, and Future,” provided deep insights into the evolving field of fluid dynamics and oceanography.

Prof. Son discussed the significant research developments made in his laboratory, highlighting cutting-edge wave and tsunami modeling techniques. An innovative aspect of his presentation was the use of virtual reality (VR) to display these models, allowing participants to experience the simulation results in a more immersive and realistic way. This approach brought the science closer to the audience, making the impacts of the models more tangible.

The guest lecture attracted both undergraduate and graduate students, particularly those enrolled in courses such as Ocean Dynamics and Geophysical Fluid Dynamics. During the session, Prof. Son elaborated on the mathematical equations used to analyze ocean waves, including tsunami propagation. He explained the differences in the outcomes when using the shallow water equations versus the Boussinesq equations, providing a comprehensive understanding of the two approaches and their respective advantages in modeling oceanic phenomena. This lecture offered valuable knowledge for students and faculty, enhancing their understanding of advanced oceanographic modeling techniques and their real-world applications.
