Snow Accumulation and Depletion Pattern of an Eastern Himalayan River Basin

Abstract

Accumulation and ablation pattern of seasonal snow are important variables in snow hydrological studies. For any snow-dominated catchment, snow accumulation and ablation patterns vary with elevation zones. The present study deals with the zone specific average snow accumulation and ablation pattern of a snow covered river basin in Eastern Himalayan region. The satellite images (AWiFS/LISS-III) of the selected basin for the accumulation as well as ablation period (October – June) were obtained from National Remote Sensing Centre (NRSC), ISRO, Hyderabad, India. GIS software, ArcGIS and ERDAS were used to determine snow covered area (SCA) percentages of different elevation zones by using NDSI model.
