Abstract
The Himalayas form the source of most of north India?s river systems, which form the life line for the millions of people living in their lower basins. The Seasonal snow cover has a significant role in hydropower generation, water management, climate study, avalanche forecasting, flood forecasting and many other developmental activities that contribute to national economy. Physical properties of a snowpack such as crystal structure, density, and liquid water content are also important for transfers of heat and water. Snow- climate feedbacks such as snow-albedo feedback mechanisms involved are often complex and are not properly understood. Considering the impact of snow properties on regional climate and subsequent impact on natural and human systems, the present study of the Satopanth and Bhagirath Kharak glaciers which are the sources of the Alaknanda river, a major tributary of the Ganga, has been undertaken. It also attempts adopted methodology for assessment of snowmelt for the Parvati Basin, a tributary of Beas river in Kullu District, Himachal Pradesh. The monthly average rainfall, temperature and discharge data at Bhuntar station (Indian Meteorological Department) was used to compute the total precipitation input over the basin. In order to find out the snow-covered area in the basin, various remote sensing datasets were used. This study makes an attempt to investigate and assess spectral properties of snow and to analyze how snow properties affect albedo and its subsequent effects on the regional climatic variability using hyper spectral datasets and then finally to assess the hydrological effects with response to variability in regional climate with the help of Snowmelt Runoff Model (SRM) while validating the results from space born spectroscopy sensor with respect to field based data collection. Thus, this study will attempt to reveals the role of the spectral properties of snow affecting climate at regional level. Finally an attempt will also be made analyze the socio-environmental vulnerability in the region due to possible climatic changes in the study area.
