Description :
This paper examines the nature and geomorphic influences of deposits from rock avalanches that obstruct rivers. These landslide barriers have created a naturally fragmented river system. Deposition and erosion in the lower few tens or hundreds of meters of the Upper Indus stream valleys have been dominated by epicycles of aggradation, trenching, and downcutting that mainly reflect the scale, timing and history of each barrier. The landforms involved are only indirectly related to the late-glacial and paraglacial conditions that have, hitherto, been regarded as the main explanation.
