| Abstract: | The movement of a glacier can redistribute glacier mass balance and change water and thermal conditions of the glacier. Thus, the glacier can maintain its dynamic balance. Surface velocity of a glacier is a basic feature of glacier movement. With successive monthly observations from 2006 to 2008, we obtained spatial and temporal variations for surface velocity of Glacier No.1 at the headwater of Urumqi River, Tianshan Mountain. Dynamic simulation was used to verify the findings. Results show that altitudinal distribution of glacier velocity was influenced by synthetic effects such as glacier thickness, slope, and bedrock morphology. However, seasonal variation was influenced by changing glacier thickness. |
