Morphometric analysis was carried out to analyse and determine the drainage pattern and morphometric characteristics of Nira river basin using topographical maps, SRTM data and geo-spatial technique. The study area, Nira river basin is one of the major tributary of Bhima river basin in Pune district of Maharashtra and it has drainage area 6879.60 sq. km. Morphometric parameters like stream order, stream length, bifurcation ratio, drainage density, stream frequency, relief ratio, elongation ratio and circularity ratio are calculated using various techniques. The morphometric analysis carried out in the Nira river basin shows that the basin is elongated basin indicating that the basin may produce flatter peak of flood for a longer duration. The basin has undulating topography. The high relief indicates that Nira river basin has a steep slope. The drainage density of the basin is 0.39 km/sq. km. It is concluded that remote sensing and GIS have been proved to be efficient tools in drainage delineation and updation. In the present study, these updated drainages have been used for the morphometric analysis.
