Abstract
Geomorphometric Modeling of Mountain Permafrost Creep Using GIS
Track: Modeling
Author(s): Regula Frauenfelder, Etzelmüller Bernd, Schneider Bernhard
Rockglaciers--permafrost creep features on mountain slopes--are common landforms in high mountain areas. The knowledge about temporal and spatial variability of regional rockglacier distribution is still relatively limited. Geomorphometry, the quantitative treatment of the morphology of landforms, provides a powerful tool to model landform distribution. The basic assumption hereby is that there exist close relationships between surface processes and particular topographic characteristics, which themselves are expressed as topographic parameters. In the present study, we applied terrain analysis and classification based on digital elevation
models (DEMs) to model the rockglacier occurrence in a study area in the Swiss Alps.
