    Abstract
  • Under the background of global warming, glaciers melt, ice tongues retreat, glacial debris flows tend to be more active. Zhamo road is now the only road to Motuo county. Galongqu develops typical maritime glacier debris flows in southeastern Tibet. Based on the field survey, Galongqu valley is investigated through three kinds of material sources including moraine, collapse and channel accumulation. Distribution characteristics and participating modes of material sources are also summarized. On account of material source calculation models, the quantitative volume may participate in the Galongqu debris flow is 366.28×104 m3, where the moraine source is dominant. The supplying of material sources here are representative in southeastern Tibet. Galongqu glacial debris flow might bear great hazard potential to Zhamo Road along with the global warming trend.
