Abstract

The aim of this study is to integrate existing field measurements and to create spatially continuous information on sediment transport rates and sediment budgets in a periglacial environment. Satellite image analysis and tools provided by geographic information systems (GIS) are exploited in order to extend and improve this research and to complement geophysical methods. The processes of interest include mass movements such as solifluction, slope wash, dirty avalanches and rock- and boulder falls. Geomorphic process units have been derived in order to allow quantification via GIS techniques at a catchment scale. Mass movement rates based on existing field measurements are employed in the budget calculations, especially from the Kärkevagge region of northern Sweden
