Abstract: Remote sensing (RS) and geographical information system (GIS) are the effective tools in delineating drainage pattern. The Meghadrigedda watershed is selected for the present study and has a gross capacity of 1169 Mc. Ft. For the identification of morphological features and analyzing their properties of the Meghadrigedda basin various GIS and image processing techniques have been adopted. The linear and aerial aspects of the basin were calculated and computed. It is 7th order drainage basin and drainage pattern is dendritic type. It is observed that the drainage density value is high which indicates that the basin has impermeable subsurface and has more surface runoff. Bifurcation ratio shows that the geological structures of basin do not distort the drainage pattern.
