Mountain environments host highly dynamical and widespread erosion, sedimentation, and weathering processes. These processes cover a wide range of temporal and spatial scales, from glacial & periglacial erosion, mechanical & chemical weathering, rock fall, debris flows, landslides, to river aggradation & incision. These processes react to a wide spectrum of external and internal forcings, including permafrost retreat, strong precipitation events, climate change, earthquakes or sudden internal failure. Measuring the dynamical interplay of erosion, sedimentation as well as quantifying their rates and fluxes is an important part of source to sink research but it is highly challenging and often limited by difficult terrain. Furthermore, these dynamical processes can threaten important mountain infrastructures and need to be understood and quantified for a better societal and engineering preparation to the natural hazards they pose.

We welcome contributions investigating:
- sediment mobilization and deposition
- links between erosion, weathering, and the carbon cycle
- concepts of dynamics and connectivity of sediments and solutes
- quantification of erosion, sedimentation, and weathering fluxes in space and time
- sediment travel times and transport processes
- interaction of stabilizing and destabilizing processes on the slopes
We invite presentations that focus on conceptual, methodological, or modelling approaches or a combination of those in mountain environments and particularly encourage early career scientists to apply for this session.
