Denudation, including both chemical and mechanical processes, is of high relevance for Earth surface and landscape development and the transfers of solutes, nutrients and sediments from slope and headwater systems through the main stem of drainage basin systems to ocean basins. Denudational slope and fluvial processes are controlled by a range of environmental drivers and can be significantly affected by man-made activities. Only if we have a better quantitative knowledge of drivers, mechanisms and rates of Holocene to contemporary denudational processes across a range of different climatic environments, an improved assessment of the possible effects of global environmental changes (e.g., higher frequencies of extreme rainfall events, accelerated permafrost thawing, rapid glacier retreat), anthropogenic impacts and other disturbances (e.g., land use, fires, earthquakes) on denudation can be achieved.

This session combines contributions on denudational hillslope and fluvial processes, sedimentary budgets and landscape responses to environmental changes in different morphoclimates, including both undisturbed and anthropogenically modified landscapes. The presented studies apply a diverse set of tools and data analyses, including up to date field measurements and monitoring techniques, remotely sensed/GIS-based analyses, modelling, geochemical and fingerprinting measurements and techniques, dendrochronological approaches, and cosmogenic radionuclide dating.

This session is organized by the I.A.G./A.I.G. Working Group on Denudation and Environmental Changes in Different Morphoclimatic Zones (DENUCHANGE).
