Processes of debris flow formation and the dynamics of glaciers in the Central Caucasus
An analysis of the reconstructed large picture of debris flowevents during the last one and a half millennia showed that, with different stages of global glacial dynamics, different mechanisms of debris flow formation prevailed in the periglacial zone. A majority of catastrophic debris flows in the Central Caucasus occurred during the stages of glacial retreat because of outbursts of numerous temporary glacial lakes near the edges of retreating valley glaciers; and from the thermal erosion of small glaciers. With the present glacial retreat in the Central Caucasus, the potential exists for increasing debris flow activity related to thermal erosion destruction of small glaciers in the near future.
