Landslides and Landscape Evolution: Mechanisms and Feedbacks
Session ID#: 74147
Session Description:
Landslides are a significant hazard, as well as a key driver of landscape evolution and the cycling of elements. Case studies, often rich in physical complexity, can be difficult to generalize across landscapes. Conversely, landscape-scale studies often trade that complexity for broad spatio-temporal applicability. While landslides are driven by local phenomena, collectively they can regulate long-term landform changes and biogeochemical cycles at regional-to-global scales. Landslide studies that span this spatio-temporal range must include both landscape-scale context and sufficient physical information to understand critical mechanics. This session seeks contributions exploring the role of landslides in a broader setting of surface processes, tectonic geomorphology, and Critical Zone sciences. We encourage submissions that advance our understanding of feedbacks between landslides, landscape evolution, and biogeochemical processes (e.g. chemical weathering), along with mechanisms of slope failure and mobility. We welcome contributions from field to modeling studies, especially those incorporating multi-disciplinary tools or datasets.
