The purpose of the project is to study the geomorphological processes that accomplish sediment transfers in mountain catchments in the Abisko area. Using both field data and remote sensing methods, an attempt will be made to model the processes and the resulting effects on landforms within a GIS. Methods of estimating process frequency or rate, e.g. by lichenometry, will be used. Main field site is the Nissunvagge valley, previously studied in the 1980´s (Nyberg 1985). The results will be evaluated from a climate change perspective.
