Description :
The AA. seek to quantify glacial erosion in a low relief shield landscape in northern Sweden. They use GIS analyses of digital elevation models and field mapping of glacial erosion indicators to explore the geomorphology of 3 granite areas with the same sets of landforms and of similar relative relief, but with different degrees of glacial streamlining. Semi-quantitative estimates of glacial erosion on inselbergs and palaeosurfaces and in valleys are derived from estimated pre-glacial regolith depths and from morphological evidence of glacial modification. Pre-glacial landform inheritance is shown to be here a major element in the development of landforms of glacial erosion.
