Cascading processes and hazards in mountainous catchments under environmental changes
Convener: Eleonora DallanECSECS | Co-conveners: Andrea BrennaECSECS, Virginia Ruiz-Villanueva, Tobias Heckmann, Martin Mergili
Hydrogeomorphic processes (e.g., mass movements such as landslides or debris flows and floods) may naturally act together or interact in a given space or time, creating cascades. The physical response of mountain catchments to these cascades is hardly predictable due to their complex nature, the interplay between different triggering and controlling factors, and the rarity of these events. These cascading processes will likely be exacerbated due to a warming climate or other environmental changes (i.e., wildfires).
Addressing the hazards and risks resulting from the combination of multiple processes faces enormous challenges, primarily from a still incomplete process interaction understanding.
In addition, expertise is scattered across disciplines (e.g., geomorphology, geology, hydrology, climate sciences) and beyond (e.g., civil engineering, social science), limiting the potential to develop and its ability to influence policy.
The session aims to shed light on the current knowledge regarding cascade hydrogeomorphic processes and their hazards and to propose novel frameworks to understand, monitor, and model their complex feedback and interactions, with a particular focus on mountainous regions affected by diverse environmental changes.
We welcome scientific contributions in the domain of cascading processes, including (but not restricted to) the study of complex feedback and interactions between hillslopes and fluvial processes. We invite contributions showing novel monitoring strategies and proposing the latest advances in experimental, theoretical, conceptual and computational tools used in analysing cascading processes. Proposed management strategies to assess cascading processes-related hazards and risks will also be well received.
