Abstract

Within this paper modern techniques such as satellite image analysis and tools provided by geographic information system (GIS) are exploited in order to extend and improve existing techniques for mapping the spatial distribution of sediment transport processes (mass movements such as solifluction, slope wash, dirty avalanches and rock- and boulder falls). They differ considerably in nature and therefore different approaches for the derivation of their spatial extent are required. A three-stepped approach has been developed which is based on the concept of Geomorphic Process Units (GPUs) : parameterization, process area delineation and combination. Parameters include land cover from satellite data and digital elevation model derivatives. Process areas are identified using a hierarchical classification scheme utilizing thresholds and definition of topology. The approach has been developed for the Kärkevagge in Sweden and could be successfully transferred to the Rabotsbekken catchment at Okstindan, Norway using similar input data
