The glacier flow velocity is one solid feature indicating changes beside other glacier characteristics. In this paper the glacier surface velocities of glaciers in the Khumbu region were measured using both manually and automated based on multitemporal Ikonos and ASTER data. ASTER data has a suitable accuracy to calculate surface velocity. Ikonos data offers more detail but requires more effort for rectification. All investigated debris-covered glacier tongues show areas with no or very slow movement rates. The surface velocity of Khumbu Glacier probably decreased in comparison with data from earlier studies. The reason might be the loss of ice mass caused by the climate change.
