WebJan 11, 2024 · The term ‘periglacial debris flow’ here refers to a special torrent containing a large amount of sediment and rocks formed by the mechanisms such as ice avalanches, rock avalanches, snowmelt, permafrost degradation, and glacier lake outbursts in the margin of modern glaciers and snow-covered areas. Periglaciation (adjective: "periglacial", referring to places at the edges of glacial areas) describes geomorphic processes that result from seasonal thawing and freezing, very often in areas of permafrost. The meltwater may refreeze in ice wedges and other structures.
