Mass movements such as landslides and debris flow, and fluvial processes (i.e., floods) may naturally act together or interact in a given space and time. The physical response of mountain catchments concerning these hydrogeomorphic processes is hardly predictable due to their complex nature, the interplay between different controlling factors, and the rarity of these events. These cascading processes will very likely be exacerbated due to climate and environmental changes. Addressing the risks resulting from the combination of multiple processes and hazards faces enormous challenges that arise primarily from a still incomplete process interaction understanding. In addition, expertise is scattered across disciplines (geomorphology, geology, hydrology) and beyond (civil engineering, social science) limiting the potential to develop, and its ability to influence policy.
This seminar aims to identify the current gaps in knowledge regarding compound and cascade hydrogeomorphic hazards and risks and to suggest new frameworks to study the complex feedback and interactions between hillslopes and fluvial processes. The goal is to boost and encourage the exchange of ideas, cooperation in research, and the crossing of disciplinary boundaries, bringing together academics (early-stage researchers and senior scientists) as well as practitioners and stakeholders.
