Description :
Current processes of gelifluction and fluvial sediment transfer have been monitored for several years in the periglacial altitudinal belt of the southern Hohe Tauern mountain range, central Alps Austria. A close connection between cryogenic processes and the destruction of vegetation cover, the intensity of gelifluction and also the amount of sediment transfer in the headwater channels can be demonstrated. Through a combination of these results with a data on Holocene slope, soil and channel dynamics, projections into the past are made possible and allow, by comparison with the vegetational and glacial history of the area paleoclimatic and paleoecologic reconstructions on a Holocene scale.
