Morphometric analysis of Morna River sub basin using geospatial approach
Authors

Abstract
The study area is part of Basaltic hard rock terrain in Central India. The study area is occupied by mainly Purna Alluvium and Basaltic lava flow of upper Cretaceous age. The aquifer characteristics of both the formation are quite different in the study area.. The drainage pattern is dendritic to sub dendritic and the sub basin of Purna River sub basin. The morphometric analysis was carried out for Morna River sub basin using the geospatial technique. The mean stream length (Lsm) values in the subwatersheds range from a minimum of 0.55 km for stream order one and 41.53 km and the mean bifurcation ratio in the study area is 4.62 and the higher values of bifurcation ratio indicates a strong structural control in the drainage pattern while the lower values indicates that the sub basin are less affected by structural disturbances. The drainage density (D) values is 1.87 km/sq. km indicating medium to high drainage density. The circulatory ratio is 0.34 which indicates that the basin is elongated in shape, low discharge of runoff and highly permeability of the subsoil condition in the given study area. The elongation ratio values of the sub-basins is 0.10 are less than 0.70 which indicates that sub watersheds are elongated with high relief and steep slope.
