Abstract


The changes in climate variability have led to a rapid retreat of mountain glacier systems which are considered the lifeline of river basins and ecosystems. Scientific studies have shown that 67 % of glaciers are retreating at a startling rate in the Himalayas as a result of various factors including climate change. Glaciers and small ice caps in temperate environments are sensitive indicators of the change in climate. Satopanth and Bhagirath Kharak glaciers are located at the head of the Alaknanda valley in Chamoli District. Retreat of the snouts and area vacated by recession of the glaciers were estimated for 51 years by way of superimposing the Survey of India Toposheets of 1962 on the map .Snouts of the Satopanth and Bhagirath Kharak glaciers recorded continuous recession for the past five decades, with decline in recession of both cases. The retreat rate of Satopanth glacier is 2.88 m/year while Bagirathi Kharak retreat at a rate of 1.21 m/year which is much more less in comparison to Satopanth glacier. Retreat in the length of Satopanth and Bagirathi Kharak glacier was 2.28km and 0.66 km respectively from the period (1962-2013). The total area vacated by the Satopanth and Bhagirath Kharak glaciers during 51years was (0.354 sq. km) and (0.14 sq. km) respectively. This paper presents the results obtained from the analysis from the set of multitemporal satellite data, SOI Toposheets 1962, Satellite data of Landsat 1976, 1990, LISSIII 2000,2010 and CARTOSAT-1& LISS IV 2013 are used in the study.
