The measurement of drainage parameters provides useful numerical measure of landscape dissection and runoff potential. This study incorporates quantitative fluvial characteristics of the Naina- Gorma river basin under linear aspects. Morphometry defined as the measurement and mathmetical analysis of the configuration of the earth surface and of the shape and dimension of its landforms (J.I Clarke, 1970). The morphometric analysis particularly deals with the quantitative measurements of different aspects of river channel for instance stream order, Bifurcation ratio, Mean bifurcation ratio, Stream length,Length ratio, Mean stream length, Length of Overland flow, Constant channel maintenance etc. The Naina-Gorma river is a tributary of the Belan River having North-South course. I have segmented the study area in to three sub-basin viz. Naina, Odda and Gorma sub- basin. So Naina -Gorma river basin comprised of three smaller sub-basins i.e. the Naina river, odda river and Gorma river sub basin. The Naina sub-basin covers an area 386.30 sq.Km, Odda sub basin covers an area 605.98 sq.Km. and Gorma sub basin covers an area 427.43 sq.Km which have been determined with the help of topographic maps of 1:50,000 scale. Total length of all tributaries is 2317.961 km. The entire drainage network is spread over shale, sandstone and alluvium. The Naina- Gorma river flows over a nearly undulating topography. The drainage pattern is dendritic to sub dendritic. The analysis were carried out under the fluvial morphometry i.e. Linear aspect.
