Topographic signatures of progressive glacial landscape transformation Moritz Liebl*, Jörg Robl, David Egholm, Günther Prasicek, Kurt Stüwe, Gerit Gradwohl, Stefan Hergarten Findings of our numerical modelling approach suggest that the emergence of glacial landforms leads to an increase in mean channel slope and its variance. Above steep flanks and headwalls, however, the observed mean channel slope remains similar to the mean channel slope of the initial fluvial topography. This leads to a characteristic turning point in the slope-elevation distribution above the long-term equilibrium line altitude. Such features are abundant in glacially imprinted mid-latitude mountain ranges such as the Eastern Alps and can be used as diagnostic features to quantify glacial imprint.
