Geographical information system has been used for the calculation and delineation of the morphometric characteristics of the River basin. The study of morphometric analysis of Tungabhadra river basin has been based on the secondary source. The Dem data (Digital elevation model) for the study area downloaded from USGS earth explorer website. The downloaded data has been analysed using Arc GIS Software. In addition, we study linear, relief and aerial parameters of drainage basin Retrieved that (indices were computed). The stream order ranges from first to six orders. The analysis has revealed that the total number and length of stream segments is maximum in first order streams and decreases as the stream order increases. The stream order of the basin is form first order to sixth order , where the total number of the streams for the basin is 2580 out of which 1326 are first order 643 are second order 378 are the third order, 120 are the fourth order,78 are the fifth order streams and 35 are the six is order. The streams have been formed in Dendric drainage pattern drainage pattern with drainage density of 0.622 km2 infers the less permeable surface of the basin with thin vegetation and moderate to high elevation. The Bifurcation ratio (Rb) between different successive orders varies revelling the geostructural the shape parameters circulatory ratio (Rc )=0.28,Elongation ratio(Re) =0.31, form factor (Rf)=0.24 indicates elongated shape of the basin which increases the chance of infiltration. These studies are very useful for identifying and planning the ground water potential zones and watershed management.
