Plio-Pleistocene topographic evolution of mid- to high-latitude mountain ranges (co-organized)
Convener: Günther Prasicek  | Co-Conveners: Jörg Robl , Stefan Hergarten , Georgina E. King 
This session welcomes studies addressing the role of glacial, periglacial, hillslope and fluvial erosion on the topographic evolution of mid- to high-latitude mountain ranges during periods of high-amplitude climatic oscillations (i.e. the last 5 Ma). We put particular focus on feedbacks between relief formation/destruction, evolving topographic patterns towards a topographic steady state, and spatio-temporal variations in erosion rate that arise from climatic fluctuations and the associated topographic response.

Such feedbacks could emerge, for example, from a dependence of erosion rates on frequency and amplitude of climate change, lithospheric loading by accumulation of ice or unloading by deglaciation or erosion, and ultimately by coupling tectonics and climate.

We explicitly encourage submissions about both numerical modelling and field studies. This includes (but is not limited to) results from morphometric analyses and from time-dependent descriptions of alpine landscapes, as well as data constraining mountain erosion and its relationship to climatic fluctuations.
