Resumo: | This paper aims to identify potential areas of landslides in the Amzaz watershed in northern Morocco with its precarious environmental balance using the Information Value (IV) Model. Van Westen (1994) defines bivariate methods as a modified form of the quantitative map combination with the exception that weightings are assigned based upon the statistical relationship between past landslides and various factor maps, individual factor maps (independent variable). A set of factor maps were overlaid with a landslide map (dependent variable) to create cross-tabulations for each one and class. The landslide inventory is used to result in the susceptibility maps for better mitigation of the risks and losses related to this phenomenon. The results demonstrated that the percentage of rotational landslides varies between 8.79 and 30.08%, and between 9.79 and 23.36% for translational slides susceptibility in the Amzaz watershed. |

Van Westen (1994) définit les méthodes bivariées comme une forme modifiée de la combinaison de cartes quantitatives, à l'exception du fait que des pondérations sont attribuées en fonction de la relation statistique entre les glissements de terrain passés et les différentes cartes de facteurs, les cartes de facteurs individuels (variable indépendante). Un ensemble de cartes factorielles a été superposé à une carte des glissements de terrain (variable dépendante) afin de créer des tableaux croisés pour chacune d'entre elles et pour chaque classe. L'inventaire des glissements de terrain est utilisé pour établir les cartes de susceptibilité afin de mieux atténuer les risques et les pertes liés à ce phénomène. Les résultats ont montré que le pourcentage de glissements de terrain rotationnels varie entre 8,79 et 30,08%, et entre 9,79 et 23,36% pour la susceptibilité aux glissements translationnels dans le bassin versant de l'Oued Amzaz.Centro de Estudos de Comunicação e Sociedade (CECS) da Universidade do Minho2021-01-27info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.21814/physisterrae.2965eng2184-626XEl-Fengour, AbdelhakBateira, CarlosEl Motaki, HanifaGarcía, Horacioinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-12-24T09:57:21Zoai:journals.uminho.pt:article/2965Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T00:56:03.991927Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |

This paper aims to identify potential areas of landslides in the Amzaz watershed in northern Morocco with its precarious environmental balance using the Information Value (IV) Model. Van Westen (1994) defines bivariate methods as a modified form of the quantitative map combination with the exception that weightings are assigned based upon the statistical relationship between past landslides and various factor maps, individual factor maps (independent variable). A set of factor maps were overlaid with a landslide map (dependent variable) to create cross-tabulations for each one and class. The landslide inventory is used to result in the susceptibility maps for better mitigation of the risks and losses related to this phenomenon. The results demonstrated that the percentage of rotational landslides varies between 8.79 and 30.08%, and between 9.79 and 23.36% for translational slides susceptibility in the Amzaz watershed. |
