My Courses

Natural hazards Geomorphology Torrent and avalanche control

Research Focus

In my research I am interested in the initiation, movement, and deposition of mountain hazard processes in the framework of an engineering risk assessment. One research focus is the flow behavior of debris flows and granular avalanches and how these processes interact with structural mitigation measures. We carry out field monitoring in torrent catchments and conduct laboratory experiments of particulate systems. We aim to transfer methods developed in the lab to the field for measuring e.g. basal stresses and velocity profiles under natural conditions. This combination of scales has implications for testing and developing advanced numerical simulation tools for hazard and risk assessment. Another research area is the investigation of hydro-meteorological and geomorphological trigger conditions of torrent processes and how climate change affects the frequency and magnitude of future events. We aim for a process-based understanding of initiation mechanics to develop a quantitative framework for prediction of torrential flows in mountain regions in a changing climate.
