Hillslope geomorphology, denudational slope processes and slope response to global climate changes and other disturbances (co-organized)
Convener: Katja Laute  | Co-Conveners: Achim A. Beylich , Sara Savi 
Hillslopes are important elements of the terrestrial Earth surface. The characteristics, development and function of hillslopes as components of the geomorphological process-response system represent a central theme in geomorphology. When the gravitational force acting on a hillslope exceeds its resisting force, slope failure (mass wasting) occurs. The rates at which mass-wasting processes act to modify hillslope morphometries are extremely varied and are driven by a number of diverse physical, chemical, and biological processes. These processes span a wide range of spatial and temporal scales and are considered to react sensitively to global climate changes (e.g. higher frequencies of intensive rainfall events, increasing permafrost thawing, rapid glacier retreat), anthropogenic impacts and other disturbances (e.g. land use, fires, earthquakes). As a consequence of ongoing and predicted global climate change mass wasting processes pose an increasing threat to human society and infrastructure.
This session focuses on Hillslope geomorphology and relief development resulting from the numerous denudational processes that govern hillslope evolution both in tectonically-seismically stable and active environments. The session welcomes process-orientated studies on hillslope and relief evolution with focus on a wide range of hillslope processes (e.g. solute, soil and mass-wasting processes). Additionally, we encourage the submission of studies connecting physical erosion, chemical weathering and climatic changes as well as hillslope-channel coupling systems ranging from tropical to cold climate environments. Studies that explore these topics with a diverse set of tools and data analysis, including up to date field measurements and monitoring techniques, seismic methods, remotely sensed/GIS-based analysis, and experimental/numerical modelling, geochemical measurements, geochronological approaches, cosmogenic radionuclide dating, and laboratory experiments are particularly welcome.
