“…The ASTER-DEM was used to create the drainage map of the research area, a satellite image from which DEM information was extracted on 10 August, 2019 (source: https://earthexplorer.usgs.gov), and reference Survey of India toposheet map at a scale of 1:50K with projection "WGS UTM 1984, Zone 43N." ERDAS-Imagine 2014 and ArcGIS 10.4 software were used for basic image processing and delineation of the catchment and stream network extraction [21,34]. ASTER-30 m DEM was used because it gives efficient results which can be utilized for meso-and micro-level watershed characterization [34].…”

“…Then, if there is an error in DEM due to missing pixels, it would be fixed, whereas if some pixels are extra, they would be removed to create a hierological corrected surface for a better analysis. The next step is the flow direction, which counts the elevation from higher to lower and assigns a number representing a direction, meaning a direction coding [21,35,36]. The flow accumulation counts how the pixels are accumulated, defining a higher number of pixels with a higher possibility of accumulation [37].…”

“…Currently, hypsometric curves are generated through GIS, and have been widely used throughout [51]. For example, many researchers have studied hypsometric analysis using GIS techniques (e.g., [18,19,21,22,39,[58][59][60]). HI was calculated based on Equation (10) in this study [47,61].…”

“…The drainage network obtained from the digital elevation model (DEM) is a more practical approach to drainage morphometric analyses (MA) [7]. Many scientists have utilized traditional methods to study the basin MP of different catchments [8][9][10][11] based on RS and GIS approaches [11][12][13][14][15][16][17][18][19][20][21][22], as such techniques are effective methods [15]. Several studies have assessed the form and processes of river basins using morphometric analysis; for example, Arulbalaji and Padmalal [23] used geospatial techniques for obtaining the drainage network of the Cauvery River basin (India), considering linear, relief, and aerial aspects.…”

India’s water resources are under tremendous pressure due to elevated demand for various purposes. The over-exploitation of these valuable resources has resulted in an imbalance in the watershed ecology. The application of spatial analysis tools in studying the morphological behaviour of watersheds has increased in recent decades worldwide due to the accessibility of the geospatial database. A morphometric analysis of a river basin is vital to determine the hydrological behaviour to develop effective management. Under the current study, morphological behaviour of Nand Samand catchment in the hard rock region was evaluated employing remote sensing (RS) and geographical information system (GIS) tools. The Nand Samand catchment (Rajasthan State, India) has an area of 865.18 km2 with the highest and lowest elevations of 1318 m and 570 m above mean sea level, respectively. This study utilises a 30 m high-spatial-resolution ASTER imagery digital elevation model for delineating the catchment. The drainage network is assessed using a GIS method, and morphometric parameters like linear, areal, and relief aspects were calculated. Results were obtained for parameters viz., basin length of 82.66 km, constant channel maintenance equal to 0.68 km, stream frequency of 2.11 km−2, drainage density of 1.48 km−1, and length overflow of 0.34 km. Form factor of 0.13, and the circulatory ratio of 0.28 showed that an elongated shape characterises the study area. The results would help understand the relationship between hydrological variables and geomorphological parameters for better decision-making. The techniques used could effectively help to perform better drainage basin and channel network morphometric analyses. The found morphometric characteristics will be helpful in understanding the Nand Samand catchment and similar areas in India in order to better guide the decision-makers in providing adequate policy to the development of the region.

“…River basins and drainage networks play an essential role for a wide range of water and land resources management applications such as flood prediction, contaminant transport, streamflow hydraulics (Jenson, 1991;Gazioğlu et al, 2014;Thomas and Prasannakumar, 2015;Çelik and Gazioğlu, 2020), and basin morphometric analysis (Horton, 1945;Strahler, 1964). For instance, the river carries nutrients, pollutants, or sediments, and water flows to the outlet of the basin in a certain period since it flows from higher to lower elevation (Kumari et al, 2021). Similarly, anthropogenic activities, especially rapid changes in land use/land cover (LULC), significantly impact rivers' flow rates and morphology (Pavanelli et al, 2019).…”

Drainage basin/watershed analysis based on morphometric parameters has an essential role in watershed management and planning. Reliable delineation of watersheds and drainage networks is critical for hydrological and geomorphological studies. Since access to high-resolution digital elevation models (DEMs) and digital surface models (DSMs) is costly, many researchers need to evaluate low-resolution open-source products. Several data sources produced from different surveying techniques are used in the morphometric analysis. In this study, five different datasets such as Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) GDEM, Shuttle Radar Topography Mission (SRTM) DEM, Advanced Land Observing Satellite (ALOS) DSM, National Aeronautics and Space Administration (NASA) DEM, and a DEM from topographic maps (TOPO DEM), were investigated based on morphometric parameters. The tests was carried out in the Saz-Çayırova Basin, which is one of the critical urbanization and industrialization regions of Kocaeli, Turkey. In this study, the TOPO DEM, whose horizontal resolution is 30 m, was produced from 1:25K scaled digitized topographical maps. It was used for comparative analysis, as in all DEMs sources. The morphometric parameters' result of the TOPO DEM was used as the reference data for comparing the results of the other DEMs sources. In addition, the mean absolute percentage error (MAPE) was used to compute the accuracy between the freely available DEMs and the TOPO DEM for each morphometric parameter. The outcomes of this study reveal that the most consistent results with the TOPO DEM are provided by SRTM DEM, following the NASA DEM.

Identi cation of critical sub-watersheds susceptible to soil erosion risk is the preliminary step in any watershed management plan. To achieve this goal, the prioritization of sub-watersheds based on morphometric characteristics is of paramount necessity. This study was performed on the Upper Shimsha-1 watershed using DEM to quantify the morphometric parameters in a GIS environment. The stream network was extracted in ArcGIS software, and the watershed was delineated into 16 sub-watersheds (SW1 to SW16). Two approaches, viz., the fuzzy analytical hierarchy process (FAHP) and compound parameter analysis methods, were employed in prioritizing sub-watersheds using 18 parameters highly related to soil erodibility. The FAHP score ranged from 0.145 (lowest priority) to 0.794 (highest priority), prioritizing sub-watersheds into 'high', 'medium' and 'low' classes occupying 10.76%, 27.23% and 62.01% of the total area, respectively. The compound parameter values ranged from 6.05 (highest priority) to 10.77 (lowest priority), and the 'high', 'medium' and 'low' classes occupied 31.84%, 16.49% and 51.67% of the total area, respectively. The common sub-watersheds from both methods under the 'high' priority class were SW14 and SW15, accounting for 10.76%, and under the 'low' priority class, SW1, SW8, SW9, SW11, SW12 and SW16 accounted for 42.66% of the total area. Hence, eight sub-watersheds were common in both prioritization methods corresponding to their respective priority classes. The integration of GIS technology, morphometry and prioritization methods has proven to be indispensable in watershed management and soil conservation efforts through this investigation. It further emphasizes the need for swift attention from decision-makers toward critical sub-watersheds.
