GIS-Based Multi-Criteria Decision Analysis Approach (GIS-MCDA) for investigating mass movements’ hazard susceptibility along the first section of the Algerian North-South Highway

Integration of multi-criteria decision analysis and statistical models for landslide susceptibility mapping in the western Algiers province (Algeria) using GIS techniques and remote sensing data

“…This method has been applied in a variety of fields to help in the process of decision-making and planning field. This technique is widely used in landslides susceptibility mapping and approved by many researchers (Ayalew et al 2005;Yalcin 2008;Yalcin et al 2011;Pourghasemi et al 2012a;Moragues et al 2021, Goumrasa et al 2021. Overall, the AHP is based on three main steps: decomposition, comparative judgment, and synthesis of priorities.…”

“…Moreover, some authors define the qualitative approaches based on subjective decision rules to assign weights to landslide conditioning factors as semi-quantitative models. This category mainly includes the multi-criteria decision analysis (MCDA) approaches which offer various tools for incorporating, ranking, and weighting the different variables, using subjective decision rules (Yalcin, 2008;Pourghasemi et al 2012a;Chen et al 2016;Pradhan et al 2016;Achour et al 2017;Moragues et al 2020;Shano et al 2020;Abija et al 2020;Goumrasa et al 2021;Roy et al 2022). Moreover, the MCDA models are relevant for all scales of the study area (Guzzetti et al 1999).…”

“…However, research on landslide susceptibility mapping is still scarce and rather insufficient as it covers limited areas in northern Algeria (Hadji et al 2013;Bourenane et al 2014;Bourenane et al 2016;Hadji et al 2017;Djerbal et al 2017;Mahdadi et al 2018;Bourenane et al 2019;Karim et al 2019;Merghadi et al 2020;Bourenane et al 2021aBourenane et al et 2021bGoumrasa et al 2021;Benbouras 2022;Bounemeur et al 2022).…”

“…In northern Algeria, landslides are among the most damaging geohazards that threaten mountainous regions, hilly terrain, agricultural fields, and even urban areas, causing significant economic losses, material damage, and human casualties (Machane et al 2008;Djerbal and Melbouci 2012;Bougdal et al 2013;Hadji et al 2013;Bourenane et al 2014;Bourenane et al 2016;Achour et al 2017;Cheikh Lounis et al 2017;Hallal et al 2017;Hadji et al 2017;Meziani et al 2017;Mahdadi et al 2018;Merghadi et al 2018;Hallal et al 2019;Mezzereg et al 2019;Bourenane et al 2021aBourenane et al et 2021bGoumrasa et al 2021;Tebbouche et al 2022).…”
