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. An improved understanding of the key drivers, mechanisms and quantitative 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, infrastructures, aquatic ecosystems, public safety, and biogeochemical cycles.
This session aims to bring together interdisciplinary scientists working across various field, experimental, numerical modelling, remote sensing and dating approaches that are advancing methods and providing new insights into (i) slope mass movements (e.g., landslides, rockfalls, and debris flows) and related hazard cascades in mountain environments, (ii) water, sediment and solute source-to-sink processes in different climatic zones (e.g., cold climate, temperate, arid and tropical regions) from small headwater to large river systems at event, seasonal, and multi-decadal scales; and (iii) the anthropogenic impacts and societal implications of changing hillslope and fluvial denudation processes and possible solutions for future sustainable management.
We particularly encourage the participation of early-career researchers and PhD students working in the fields of geomorphology, hydrology, hazards, glaciers, permafrost and aquatic ecosystems, as we wish to expand and integrate the international network of researchers addressing this complex subject across scientific disciplines.
This session is co-organized by the IAG Working Group on Denudation and Environmental Changes in Different Morphoclimatic Zones (DENUCHANGE, 2017-2026).
