Disputation: Matthias Rauter
Doctoral candidate Matthias Rauter at the Department of Mathematics, Faculty of Mathematics and Natural Sciences, is defending the thesis Multiphase Navier-Stokes Equations applied to landslide tsunamis: Numerical simulations of granular flows and their interaction with water bodies for the degree of Philosophiae Doctor.

The University of Oslo is closed. The PhD defence and trial lecture will therefore be digital and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the audience to ask questions ex auditorio at the end of the defence. If you would like to ask a question, click 'Raise hand' and wait to be unmuted.
- The webinar opens for participation just before the disputation starts, participants who join early will be put in a waiting room.

Main research findings
Landslides can generate large tsunamis when falling into lakes and the sea. In order to protect coastal areas and communities we need to predict these events. Mathematical models have become a popular method for this task. However, current models neglect various aspects of either the landslide or the tsunami and predictions can be uncertain and unreliable. In my thesis I developed a model that considers the most important characteristics of landslides, tsunamis and their interaction. The model is tested with a large range of small scale laboratory experiments and with the simulation of a real event. The model gives us new and detailed insights into these catastrophic events. It improves our understanding and our capabilities to predict and mitigate future events.
