Mountain belts are characterized by the fastest rates of physical erosion and chemical weathering around the world, making them one of the best places to observe sediment production (e.g. erosion, weathering) and transport processes. In these settings, varied processes such as rockfall, debris flow, hillslope failure, glacial and periglacial erosion, fluvial erosion, transport and deposition, and chemical weathering operate, often simultaneously, over a wide range of temporal and spatial scales.

As a result, tracking the interactions between denudation, climatic forcing, tectonic activity, vegetation and land use is complex. However, these feedbacks affect both long- and short-term natural surface processes, landscape development, and human interactions with the environment. Many of these processes also pose serious threats to the biosphere, mountain settlements and infrastructure. Therefore, understanding and quantifying rates of erosion, weathering, 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, and (3) consider how these processes contribute to natural hazards specific to mountain landscapes. 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.
