“…AHP is a MCDM (Multi criteria decision making) method that uses a pairwise comparison procedure to determine the preference scale between alternatives (Saaty 1980). According to the review, various studies have suggested that AHP (Analytical Hierarchy Process) provides a viable decision among different alternatives in watershed prioritization by reducing biases among the parameters (Kundu et al 2017;Gaikwad & Bhagat 2018;Balasubramani et al 2019;Bera & Banik 2019;Kumar & Sarkar 2022;Shivhare et al 2022). On the contrary, few researchers have claimed that VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) method has higher accuracy for prioritization (Amiri et al 2018;Arab et al 2018;Bhattacharya et al 2020;Meshram et al 2020;Taek et al 2022).…”

The current study used satellite imagery datasets to extract various morphometric parameters in a geospatial environment to prioritize the problematic areas in the Rarhu watershed of Ranchi district, Jharkhand, India. Two decision-making methods, AHP and VIKOR, were integrated for prioritizing different sub-watershed. The Rarhu watershed has an area of 630 km2 with an elevation ranging from 824 to 210 m. NASADEM was used to extract drainage networks which were verified from Survey of India (SOI) toposheets. To prioritize 21 sub-watersheds using the MCDM method, 11 morphometric parameters were selected from linear, areal, and relief parameters. The VIKOR method prioritized sub-watersheds using AHP criteria weights, which are classified into four priority levels ranging from very high to low. In addition, performing sensitivity analysis validated the robustness of the decision-making model. As per the analysis, Rarhu watershed has an elongated shape and the highest 6th order stream with a dendritic pattern of streams. Nearly 36.17% of the area is more vulnerable with very high priority. Using the results of the study, policymakers, watershed planners, watershed development programme, and soil and water conservation programme can identify vulnerable sub-watersheds that require urgent adaptation of soil and water management control measures.

“…A methodological approach used in environmental diagnoses of watersheds refers to morphometric analysis. Such an approach has applications in the analysis of risks of floods and erosive processes (COSTA & LEITE, 2020;TESEMA, 2022), environmental and territorial management (SILVA & MEDEIROS, 2017;SHIVHARE et al, 2022), and forest hydrology (CARDOSO et al al., 2006).…”

The present study aimed to carry out a morphometric analysis of the watershed of the Redenção stream in the municipality of Rio Branco, state of Acre. Satellite image was used as a basis for interpreting the characteristics of the basin, as well as for mapping land use and gauging linear and area measurements. In addition, Acre state databases were used in QGIS software to interpret soil type, geomorphology and geological formation. The main river in the basin is the Redenção stream, of fifth order. The basin has an area of 194.26 km² and a perimeter of 68.38 km, elongated shape and low susceptibility to flooding. There is a predominance of luvissolhypochromicorthic and eutrophic red argisol , lower sol imões geological formation and predominantly homogeneous relief, with little declivity. It has human occupation, with predominance of pasture areas and patches of urban occupation, in addition to scarce dense vegetation cover.

“…Singh et al (2021) identified flash-floods-prone river reaches in the Beas basin, Himachal Pradesh, India by implementing AHP. Shivhare et al (2022) applied AHP for geospatial modelling and watershed prioritization of the Parvati River basin in India using morphometric parameters. The aim of this research is to investigate geomorphological parameters of the Sinai Peninsula watersheds to estimate the sensitivity and mitigation of flash flooding, using RS, GIS and a ranking approach based on the analytical hierarchy decision-making process.…”
