UPPER BETWA RIVER WATERSHED MANAGEMENT AND DEVELOPMENT PLAN USING REMOTE SENSING AND GIS

Watershed management involves management of the land, water and biological resources of a region. In the study Upper Betwa Watershed basin has been taken under investigation. During study complete inventory on geology, hydrogeomorphology, land-use, land-cover and the structural units contained in the watershed basin has been prepared. LANDSAT ETM+ Satellite data and DRM is used to demarcate hydrogeomorphological landforms and lineaments to evaluate groundwater potential of the study area. Land-use land-cover (LULC), geological and lineament maps have been generated from satellite data, with the help of ArcGIS and ERDAS imagine processing. Upper Betwa Watershed basin is occupied mostly by hard rocks and half of the portion in the study area is covered mainly by both wet and dry cultivation. The major geomorphic units identified in the study area are extremely rugged, hilly and undulating topography, comprising scattered and elongated hills, parallel linear ridges, flat plateau etc. Land-use land-cover mapping shows that most part of the watershed basin is occupied by agricultural land and forest area. Field observations showed that ground water occurs under unconfined conditions with varying water table shallow to deep depth.
