The study of morphometric analysis of Tungabhadra drainage basin has been conducted based on the secondary source, the SRTM data has been downloaded from GLCF website. The downloaded data has been analyzed using ArcGIS software, the study Linear, Relief and Arial aspects of drainage basin retrieved that, total numbers of streams are 11894, in that 6058 are first orders, 3446 are second orders, 1345 are third orders and 1045 are fourth order streams. The streams have been formed in dendritic drainage pattern. The length of stream segments is maximum for first order stream and decreases as the stream order increases. The result of drainage density shows the value 0.11 per square kilo meters in study area, which suggesting that the area has highly permeable subsoil, dense vegetation cover and low relief.
