The drainage morphometric analysis proves a viable method of characterizing the hydrological response behaviour of the watershed. Geographical information system (GIS) has emerged as an efficient tool in delineation of drainage pattern and ground water potential and its planning. The study area is one of the watershed of Vena river, lies between 20° 35’00’’ N to 20° 50’00’’N latitude and 78° 57’ E to 79° 22’30” E longitude and is located in the south-east side of Nagpur district in the central India with an area about 647.516km2. It is covered in the Survey of India (OSM) toposheet numbers F44- S/13, S/14, T/01, T/02, T/05 and T/06 on 1:50,000 scale in Nagpur District, Maharashtra, India. The drainage network shows dendritic to sub-dendritic pattern and is non-perennial in nature. The present study deals mainly with the geometry, more emphasis being placed on the evaluation of morphometric parameters such as stream order (Nu), stream length (Lu), bifurcation ratio (Rb), drainage density (D), stream frequency (Fs), texture ratio (T), elongation ratio (Re), circularity ratio (Rc),and form factor ratio (Rf) etc.. The understanding of streams in a drainage system constitutes the dendritic to sub- dendritic drainage pattern, which in turn replicates mainly structural/lithologic controls of the underlying rocks and the area is hard rock terrain. The entire study area has been divided into thirteen sub-watersheds.

Key words: Watersheds, Morphometry, Remote Sensing and GIS.
