GM4.2

Erosion and sedimentation processes dominate mountain landscapes over a wide range of temporal and spatial scales. Signals from processes such as glacial and periglacial erosion, chemical weathering and mechanical weathering (i.e. progressive failure through cyclic and static fatigue), rockfall, debris flow, and hillslope failure are preserved in downstream patterns of river and/or valley aggradation and incision. These processes react to a wide spectrum of external and internal forcings (e.g. climatic variability, seismic activity or sudden internal failure) often making it difficult to relate these records back to specific causal mechanisms.

Measuring the dynamical interplay of erosion and sedimentation as well as quantification of rates and fluxes associated with landscape evolution in mountainous environments is a crucial but challenging component of source-to-sink sediment research. Furthermore, with many of these processes posing a serious threat to mountain settlements and infrastructure, they need to be understood and quantified for a better preparation from both a societal and engineering point of view.

We welcome contributions investigating the processes of production, mobilisation, transport, and deposition of sediment in mountain landscapes; the role these processes play in the larger source-to-sink context; or how they contribute to natural hazards specific to mountain environments. We invite presentations that focus on conceptual, methodological, or modelling approaches or a combination of those in mountain environments across a variety of timescales. We particularly encourage early career scientists to apply for this session.
