Abstract: Uttarakhand is one of the worst disaster prone states of the India. The state is prone to disasters due to number of factors; both natural and anthropogenic, including adverse geo-climatic conditions, topographical features, environmental degradation, population growth, non scientific development practices etc. In the present paper, an attempt has been made to study detail physiographical aspects of flood disaster in uttarakhand, which itself are west part of the uttarakhand - 1. Dehradun, 2.Haridwar, 3.Garhwal, 4.Tehri-garwal, 5.Rudraprayag, 6.Uttrakashi. For detailed study, we used the geographical information system (GIS) and Remote Sensing (RS) techniques were applied to prepare various thematic maps for the study area. Land use/ land cover, Geomorphology and lineament maps were prepared by visual interpretation from IRSP6 LISS-III Imagery. Slop and aspects, drainage density map was prepared from drainage map using SOI topographical sheet on 1:50,000 scale, lineament intersection and lineament density maps were derived from the lineament map, soil map prepared for existing soil survey and agriculture department map. All the above thematic maps were digitized and converted into real world-co-ordinate system on ARC GIS. GIS overlay analyses were carried out and hazards map was prepared. These studies are very useful for mitigation and management of flood disaster in uttarakhand.
