Denudational hillslope and fluvial processes, associated source-to-sink fluxes and sedimentary budgets are controlled by a range of environmental drivers and anthropogenic activities, exacerbated by the consequences of climate change. A better understanding of the drivers, mechanisms and rates of contemporary denudational hillslope and fluvial processes as well as of the sediment and hydrological connectivity across a range of different spatio-temporal scales and climatic zones has significant societal implications for water quality, hydraulic infrastructures, aquatic ecosystems, public safety, and biogeochemical cycles.

The session aims to bring together interdisciplinary researchers working across field, experimental, numerical modelling, remote sensing, and dating approaches who are advancing methods and providing new insights into: (i) slope mass movements (e.g., landslides, rockfalls, and debris flows) and related hazard cascades in mountainous environments; (ii) water, sediment and solute source-to-sink processesin different climate zones (e.g., cold climate, temperate, arid and tropical regions) from small headwaters to large river systems at event, seasonal, and multi-decadal scales; and (iii) the anthropogenic impacts and societal implications of changing hillslope and fluvial processes and possible solutions for future sustainable management.

We encourage the participation of early-career researchers and PhD students working in the fields of geomorphology, hydrology, hazard, glaciers, permafrost, and aquatic ecosystems, as we aim to expand and integrate the network of researchers addressing this complex subject across scientific disciplines.

This session is organized by the International Association of Geomorphologists (IAG) Working Group on Denudation and Environmental Changes in Different Morphoclimatic Zones (DENUCHANGE).
