EP24B:
Landslides and Landscape Evolution: Mechanisms and Feedbacks III


Submit an Abstract to this Session


Session ID#: 61807

Session Description:
Landslides pose a significant hazard to communities on human timescales while their long-term behavior modulates the pace and style of landscape evolution. Case studies, often rich in physical complexity, can be difficult to generalize across landscapes. Conversely, landscape evolution studies often trade that complexity for broad spatio-temporal applicability. While landslides are driven by local phenomena, collectively they can shape long-term hillslope and channel evolution regionally or globally. 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 surface processes setting. We encourage submissions that advance our understanding of feedbacks between landslides and landscape evolution, such as the signatures of landslides in hillslope and channel processes, along with mechanisms controlling slope failure and mobility. We welcome contributions from field to modeling studies, especially those incorporating multi-disciplinary tools or datasets.
