In this paper, an attempt has been made to study the morphometric characteristics of the Karha river basin which is a left-bank tributary of the Nira River in Maharashtra. The Alos Palsar DEM data having a spatial resolution of 12.5 meters and SOI Toposheet 1:50000 scale were used for quantification of morphometric parameters. The Karha valley is considered to have a 7th order trunk stream according to this study. It has a total of 5096 streams whose total stream length is 3781.7 km. The mean bifurcation ratio is 3.71. The basin area of the Karha River is 1342.65 Km2 which is covered by hard massive and vesicular amyloidal basalt rocks. Its circulatory ratio is 0.28, the form factor is 0.11, elongation ratio is 0.30, and drainage density is 2.82. The relief aspect of the Karha river watershed revealed that the relief ratio is 0.0074, absolute relief is 830M, ruggedness number is 2.34, and the channel gradient is 2.36. It is observed that the Karha watershed has a dendritic type drainage pattern. It is highly eroded and elongated in a shape manner.
