GEOMORPHOLOGICAL ANALYSIS OF MANDAKINI RIVER BASIN USING REMOTE SENSING AND GIS TECHNIQUES

Abstract

Geomorphology is important for the understanding of Earth surface processes, geochronology, natural resources, natural hazards and landscape evolution. Present study analysis’s the Geomorphological analysis of the basin like geomorphology, lineaments, lithology, land use/land cover, DEM, slope and aspects. The present study is based on spatial data acquired form of Survey of India topo-sheets, ASTER GDEM (2011) and BHAVAN (bhavan.nrsc.gov.in). Mandakini River is a major tributary of Alaknanda River and it originates from the Chorabariglacier. The total catchment area of the river is near about 1666.34 km². The Remote Sensing and GIS techniques have been used to complete the work on present study. The geoinformatics-based study of Geomorphological analysis of river basin characteristics can be used by local people for sustainable development of this area.
