Abstract
Paraglacial geomorphology is the study of the ways in which nonglacial earth-surface processes conditioned by glaciation and deglaciation affect glaciated landscapes during and after ice retreat. Paraglacial landscape modification encompasses rockfalls and rock-slope failures, mass movement on sediment-mantled slopes, modification of glacier forelands, adjustments of fluvial systems to changing discharge and sediment flux, lacustrine and fjord sedimentation, and the sediment budget and associated landforms of barrier coasts. Most paraglacial processes peak in intensity soon after deglaciation, but may be rejuvenated by extreme climatic events, changes in base level, seismicity and anthropogenic activity. The duration of paraglacial effects ranges from decades on some recently deglaciated terrain to >105 years in large catchments and along some barrier coastlines.
