Landslides, Rockfalls, and Debris Flows: The Influence of Mass Wasting on Large-Scale Sediment Dynamics

Session ID#: 158612

Session Description:
Landslides, rockfalls and debris flows shape Earth's surface and are a dominant source of sediment. Sediment routing systems then act as conveyor belts, evacuating landslide-produced sediment and transporting it to depocenters. Landslide-derived sediment can be deposited, stored, remobilized, and physically and chemically altered during its journey from source to sink. Understanding sediment generation by landslides, as well as interactions between landslides and other geomorphic processes, is important for predicting the response of Earth's surface to past and future environmental changes and for mitigating natural hazards.
This session invites research studying the role of landslides in a source-to-sink framework over all space and timescales. We seek submissions exploring the role of climate, tectonics, and human impacts on the generation of landslides and their associated sediment dynamics. We especially encourage studies investigating dynamic feedbacks among landslides, sediment routing processes, and human modification to landscapes. We welcome contributions using any combination of field, experimental, theoretical or numerical approaches.
