“…Although river delineation is an appropriate step, building a geometric network from the output enables more sophisticated forms of analysis. Most applications employing the use of hydrological networks usually require topological information such as flow direction and connectivity rules (Sindhu et al, 2015). As shown in Figure 7, this study was able to produce a geometric river network for the entire study area.…”

“…The value of the bifurcation ratio (Rb) is 5.46 which means the characteristics of the watershed suffered structural disturbances (Patil and Mali, 2013). The drainage density of the watershed is 1.66 km/km 2 which means the area is coarse texture which occurs in regions with high permeable sub soil under dense vegetation cover (Panhalkar et al, 2012;Sindhu et al, 2015). The elongation ratio obtained is 0.86 which indicates that the catchment is oval in shape (Rai et al, 2018).…”

The present study emphasize on the adequacy and advantage of remote sensing and GIS-based techniques to identify and assess the resource potential zones in Takoli Gad Watershed, India. Different thematic maps like elevation map, drainage map, soil map, geology map, slope map, rainfall map and land use/land cover map have been prepared using ASTER DEM, LISS IV and SOI topographical maps and suitable secondary data. The present study aimed to investigate various morphological characteristics by measuring linear, areal and relief aspects. The morphometric characterization indicate dynamic role in distinguishing the topographical and hydrological behaviour of the watershed. A composite map of the Resource Potential Zones was developed by integrated different thematic maps and morphometric characterization data base. In this study, geographical information system (GIS), remote sensing, weighted overlay analysis and analytical hierarchy process (AHP) methods have been used for mapping of available natural resources in the Takoli Gad watershed. The overlaid based on analytical hierarchical process weightage prioritization at a constituency ratio of 0.095. The resource potential zones categorizes into the excellent (1.59 %), good (25.61%), moderate (45.21 %), poor (26.41 %), and very poor (1.18 %) zones. The present study helps in the sustainable management of water, agriculture, forest and other natural resources to meet the basic minimum needs of people, and improve their socio-economic conditions. Decision and policy makers can use the information gathered from such case study for long term development plan of watershed.

“…The physical characteristics of drainage basins, including their dimensions, configuration, gradient, drainage density, and the quantity and length of their tributaries, may be associated with several important hydrological phenomena [14]. For a complete comprehension of how flow patterns affect landscapes and their features, it is very helpful to do a detailed morphometric study of a basin [15]. In order to conduct an in-depth morphometric investigation, Slope and aspect maps, as well as digital elevation models (DEMs), were produced using SRTM data.…”

Watershed management is a prerequisite for achieving sustainability. Insufficient financial and human resources make it impossible to properly execute management and conservation measures across broad watersheds. In order to attain sustainability, watershed management is crucial. Large watersheds provide a challenge because of the lack of funding and human resources necessary to effectively manage and conserve the whole region. The morphometric analysis was used to determine various linear as well as aerial characteristics, including stream length, bifurcation ratio, drainage area, flow length, slope, drainage density, stream frequency, shape factor, and relief ratio. Given the significance of the SRTM-DEM extract from the USGS earth explorer and the QGIS used for the assessment of drainage and the determination of them with respect parameters for the related information at the Badvel Tank (Kadapa district), Venkatachalam Cheruvu (Nellore district), and Kalangi Reservoir (Chittor district), the current study was conducted. The findings of this study can serve as a valuable resource for recommending infrastructure in specific watersheds and aiding local government officials in making informed decisions regarding irrigation and water resources. Additionally, the study demonstrates that hydrological evaluation at the watershed level using SRTM DEM is a more practical and accurate approach compared to other existing techniques.
