Mountain ranges experience some of the fastest rates of physical erosion and chemical weathering around the world, making them one of the best places to observe sediment production and transport processes. These dynamic environments host a wide range of processes, such as rockfall, debris flow, hillslope failure, glacial and periglacial erosion, fluvial erosion, transport and deposition, and chemical weathering, that often operate simultaneously, across diverse temporal and spatial scales.

As a result, tracking the interactions between denudation, climatic forcing, tectonic activity, vegetation and land use is complex. Yet, these feedbacks affect both long- and short-term natural surface processes, landscape evolution, and human-environment interactions. Many of these processes are further intensified by climate change, posing increasing threats to the biosphere, mountain settlements and infrastructure. Understanding and quantifying rates of erosion, weathering, transport and deposition within mountain landscapes is a challenging, but crucial research topic in Earth surface processes.

We welcome contributions that (1) investigate the processes of production, mobilisation, transport, and deposition of sediment in mountain landscapes, (2) explore feedbacks between erosion and weathering due to natural and anthropogenic forcings, including climate change, and (3) examine how these processes contribute to natural hazards specific to mountain regions. We invite presentations that employ observational, analytical or modeling approaches in mountain environments across a variety of temporal and spatial scales. We particularly encourage early career scientists to apply for this session.
