EP52B:
Landslides and Landscape Evolution: Mechanisms and Feedbacks I

Submit an Abstract to this Session



Session ID#: 35351

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 each landslide is localized, hillslope mass failures can be critical in long-term hillslope evolution. 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, as well as mechanisms controlling slope failure and mobility. We welcome contributions from field to modeling studies, especially those incorporating multi-disciplinary tools or datasets.
