Hydrological assessment and characterization of the micro-watersheds of Sarada river basin is done through the analysis and evaluation of various drainage and topographic parameters. The geomorphometric approach involving the analysis of multi-thematic and spatio-temporal parameters has largely helped in the logical assessment of hydrological character of the basin. The analysis of various linear and areal aspects have revealed that the topographical configuration and geomorphic setting of the basin has assumed a dendritic to sub-dendritic drainage pattern with 7th order drainage. Consequently, the study helped in the identification and mapping the potentiality of land-water resource majorly contributes for the sustenance of the basin. Based on its natural setting and availability of land-water resource, the entire basin is divided into 60 micro-watersheds which can be further treated as a base unit for the assessment and evaluation of resource potentiality. The study has demonstrated the significance of geo-morphometry as well as utility of remote sensing and GIS technology in hydrological characterization of the basin at micro-watershed level.
