- Abstract:
- There are a number of glacial lakes in Palongcangbu basin along the south section of the Sichuan-Tibet highway(in Tibet).Due to global warming and increasing melting of glaciers in recent decades,glacial lake outbursts and the resulting hazards have caused catastrophic disasters.Based on the previous researches,Landsat TM satellite remote sensing images,and field surveys,several typical glacial lakes have been studied in details.Focus is put on the major factors impacting the dam-break,including the geometric shape of the lake,the overflow regime,the stability of ice moraine-dam,and the activity of glaciers.It is concluded that Guangxie lake is of the highest potential of break to cause huge disaster,and Duoyi lake is the next.Based on the risk assessment,it is proposed to take countermeasures to mitigate the debris flow harm of Midui gully.
