Drainage morphometric analysis is very important to understand the hydrological and morphological characteristics of any region. Geographic Information system (GIS) technique is appropriate tool for the identification of geomorphological features. GIS and image processing techniques can be used to define morphological characteristics and to investigate the characteristics of the basin. The present study focused on the morphometric analysis of Nandani watershed using RS and GIS techniques. The study area has been classified into seven sub-watersheds, which have ordered SW1–SW7. The very important quantitative watershed aspects such as linear, relief and areal have been taken in consideration for morphometric analysis of watersheds, and eighteen morphometric parameters have been selected and used for ranking and prioritizing of sub-watersheds. In this regard, sub-watersheds (SW2, SW1 and SW4) and (SW6, SW5 and SW3) have categorized into higher and medium priorities, whereas sub-watershed (SW7) has assigned at lower priority. This shows that SW7 is relatively sustainable than other sub-watersheds, on the contrary, SW2 is relatively affected sub-watershed by runoff and soil erosion that needs first priority for management practices. For this study, all the satellite data is obtained from Bhuvan website and analyzed in ArcGIS software. Morphometric analysis of watershed was performed by determining the parameters like Linear Aspects, Basin Geometry, Drainage Texture Analysis, Relief characteristics. The drainage pattern of stream network from the basin have been observed as mainly dendritic type. Watershed boundary, flow direction, flow accumulation, flow volume flow ordering have been prepared using a hydrological tool and the slope aspect has been prepared using a surface tool in ArcGIS. The study is very useful for design and development of soil and water conservation practices such as bunds, check dams, micro-basins and multipurpose tree species planting based on suitable location and design parameters.
