Natural hazards, such as floods and slope failures, mobilize large quantities of sediment in fractions of time. Yet, their impact on sedimentary systems and landscape evolution can last from the event scale to millions of years. Understanding sediment generation by natural hazards, as well as the interactions between natural hazards and other source-to-sink processes, is important for predicting the response of planetary surfaces to past and future environmental change. This session invites contributions on the role of natural hazards in source-to-sink systems over all spatial and temporal scales. Likewise, we are interested in how source-to-sink studies contribute to understanding past or future hazards.
We welcome research on a wide range of hazards including landslides, rockfalls, rock avalanches, debris flows, volcanic eruptions, flooding, tsunamis, and climate warming-induced hazards like thawing permafrost and retreating glaciers. We seek submissions that explore the roles of climate, tectonics, and human impacts on natural hazards and sediment dynamics. We especially encourage studies investigating dynamic feedbacks among natural hazards, sediment routing systems, and human modification of the landscape. We welcome contributions using any combination of field, experimental, theoretical, or numerical approaches.
