Sub-watershed prioritization of Koyna river basin in India using multi criteria analytical hierarchical process, remote sensing and GIS techniques

Prioritizing sub-watersheds for soil and water conservation via morphometric analysis and the weighted sum approach: A case study of the Geba river basin in Tigray, Ethiopia

“…In this situation, indirect assessment methods such as morphometric analysis combined with statistical approaches are viable options. Among the other methods used in conjunction with morphometric analysis are principal component analysis ( Meshram and Sharma, 2017 ; Arefin et al., 2020 ), weighted sum approach ( Aher et al., 2014 ; Jothimani et al., 2020 ) and multi criteria decision ( Ahmed et al., 2018 ; Shelar et al., 2022 ).…”

“…The weighted sum approach, one of the prioritization methods, was used for this purpose ( Malik et al., 2019 ). This method includes preliminary priority ranking, correlation matrix generation, weightage calculation, compound factor estimation, and ranking ( Jothimani et al., 2020 ; Shelar et al., 2022 ).…”

“…This approach is useful for the evaluation of the hydrogeological property, landform process, runoff, and erosion ( Strahler, 1964 ). More importantly, it is an appropriate choice for prioritization of watersheds in areas where soil and hydrology data are insufficient ( Biswas et al., 1999 ; Gajbhiye et al., 2014 ; Shelar et al., 2022 ).…”

Development of a Land Suitability Analysis Model for Slums Relocation: The Case of Cairo, Egypt

“…Researchers have found that the increasing number of criteria, variety of data kinds, and measurement units make it impossible to evaluate criteria in site selection quantitatively and that there are interactions between the criteria (Sarıçam and Yilmaz, 2022). Hence, The GIS-based spatial analytical hierarchy process (SAHP) was employed to generate the weights of the criteria and rank the alternatives utilizing pairwise comparison matrix (Shelar et al, 2022). The AHP is a multiple criteria decision-making approach that employs analytical hierarchies to assess the significance of criteria and the relationships among each other in complex circumstances (Liu et al, 2015).…”

Watershed prioritization of Kailali district through morphometric parameters and landuse/landcover datasets using GIS

“…So, watershed prioritization is necessary for the effective management of watersheds. Watershed prioritization is the process of identification and ranking of environmentally degraded Sub-watershed for the prevention of soil erosion, management of floods, drought, and application of varying levels of conservation treatment [ 5 , 6 ]. The prioritization uses the key issue of the watershed problem, including erosion, as the principal consideration [ 7 ].…”
