The present study aims to find out the spatio-temporal variation of SCA and inter-relationship between snow accumulation and topography in the Upper Ganga River Basin (UGRB) including Bhagirathi, Alaknanda, Mandakini and Pindar River sub-basins, central Himalaya using MODIS Terra (MOD10A2) data. SCA is found ?32.33% to the total basin area of ?18724 km2 in UGRB. The Average of 12 year shows that Bhagirathi River Basin has maximum SCA?33.25%, whereas Pindar river basin has minimum SCA ?17.50% among these four sub-basins. Maximum rate of change of SCA is found in the Mandakini River Basin. Slope class 20��30�has more favorable conditions for snow accumulation. North and north-west aspect has higher snow accumulation with maximum positive attribution in January and minimum in July. � 2020 Informa UK Limited, trading as Taylor & Francis Group.aspectelevationMODISslopeSnow coverUpper Ganga River BasinArticlehttps://doi.org/10.1080/10106049.2020.1762764
