Description :
The AA. estimate the spatial changes in the Jaundhar, Jhajju and Tilku glaciers in the Tons River basin (Garhwal Himalaya) between 1962 and 2010 using Landsat Satellite data, topographic maps along with field surveys. They estimate the overall shrinking in the area of the glaciers. However, frontal retreat rates are not uniform in all glaciers even under the same climatic domain. Study on the fragmented glaciers shows a continuous and unusual retreat of glaciers after 1990. This uncertainty may possibly be due to size, surface morphology and gradient of the individual glaciers and can be attributed to degeneration and rapid melting on the glaciers. Meteorological data available from this region show increasing summer temperature and less winter precipitation in last few decades. Further more studies on these glaciers will shed light on several factors influencing changes and retreat on the Himalayan glacier systems.
