GM4.5

Denudation, including both chemical and mechanical processes, is of high relevance for Earth surface and landscape development and the transfer of solutes and sediments from headwater systems through main stem of drainage basin systems to the world oceans. Denudational hillslope and fluvial processes and associated source-to-sink fluxes and sedimentary budgets are controlled by a range of environmental drivers and can be significantly affected by climate change and anthropogenic activities.
The better understanding of possible effects of ongoing and accelerated environmental changes on present-day denudation requires systematic and quantitative studies on the actual drivers of denudational processes. Only if we have an improved quantitative knowledge of drivers and rates of contemporary denudational hillslope and fluvial processes as well as of the connectivity in landscapes and between hillslope and fluvial systems across a range of different spatio-temporal scales and selected climatic zones, possible effects of global climatic changes (e.g., increased frequencies, durations and intensities of dry spells, droughts, storms, extreme rainfall events and floods, accelerated permafrost thawing, rapid glacier retreat), anthropogenic impacts and other disturbances (e.g., land use, mineral exploration, mining exploitation, fires, earthquakes) on terrestrial landscape systems can be better assessed. Special focus should be given to selected cold climate, temperate, arid and tropical regions that are expected to react particularly sensitive to ongoing and accelerated environmental changes.
This session invites scientific contributions on denudational hillslope and fluvial processes, mass transfers, sedimentary budgets and landscape responses to ongoing and accelerated environmental changes in different climatic zones. Oral and poster contributions can cover a wide range of different spatial scales, from hillslope and small headwater systems to large drainage basin systems. The session shall bring together and discuss a wide range of advanced techniques and methods of data collection and generation, including field-based, laboratory-based, remotely-sensed and dating techniques together with various approaches and methods of data analysis and geomorphologic modelling.

The session is organized by the IAG Working Group on Denudation and Environmental Changes in Different Morphoclimatic Zones (DENUCHANGE).
