Abstract:

 The debris flow caused by flood of glacierlake break is a major disaster to Southeast Tibet. Based on field investigation and data analysis, this paper discusses the influences of climate factors on the lake break. It is found that the break is likely to occur after the abnormal changes in climate, especially at the turn from coldwet weather to hotdry weather. Debris flows due to glaciers will be more active in the future decades.

Key words: debris flow induced by glacierlake break; climate change; disaster; Southeast Tibet
