Abstract:
Glacier-related debris flow is the result of recession of glacier. With the recession of glacier, snow line rise, glacial ablation is intensified which increase the runoff, expand the glacier lake and thaw the frozen soil. Then under the influence of the steep terrain, with the abundant moraine came from glacier and loose material distributed along the river, it is easy to cause large-scale glacier-related debris flow. Modern glacier debris flow is mainly distributed in the high mountain which glacier retreat. Its distribution density influenced by the hydrothermal conditions physical properties and the type of glacier. Under the background of global warming, glacier-related debris flow break out more frequently. Glacier-related debris flow have always been ferocious and destructive. It break out suddenly on a horrific scale without any bodement and cause great damage to local people's life and property which aroused considerable public concern. So it is meaningful to figure out the evolution process and activity discipline of the glacier-related debris flow, to do some research upon precautionary measure, in order to reduce casualties and economic losses. This paper review the development in glacier-related debris flow research explore its time and space distribution reveal its evolution and and look forward prospective direction of the research.
