Every year in Côte d’Ivoire, during the rainy season, several localities, including those within the Marahoué watershed, are subject to recurrent floods that cause loss of human lives, population displacement, and significant material damage. Identifying areas sensitive to this phenomenon is therefore crucial for the implementation of effective and sustainable preventive measures. This study thus aims to identify flood-prone zones in the Marahoué watershed by using current physical and hydrological characteristics derived from remote sensing observations, with the goal of supporting decision-makers in their sustainable development projects. The methodological approach employed begins with the delineation of the watershed into sub-basins, followed by the extraction of topographic, morphometric, hydrological, and environmental parameters associated with flooding, and the identification of sensitive areas through game theory algorithms (Borda and Condorcet). The results indicate that the downstream areas of the Marahoué watershed, particularly those located along the main river course, are highly sensitive to flooding. Conversely, upstream areas, which are generally situated at higher altitudes, were classified within the low to very low flood risk categories.

Abstract
Every year in Côte d’Ivoire, during the rainy season, several localities, including those within the Marahoué watershed, are subject to recurrent floods that cause loss of human lives, population displacement, and significant material damage. Identifying areas sensitive to this phenomenon is therefore crucial for the implementation of effective and sustainable preventive measures. This study thus aims to identify flood-prone zones in the Marahoué watershed by using current physical and hydrological characteristics derived from remote sensing observations, with the goal of supporting decision-makers in their sustainable development projects. The methodological approach employed begins with the delineation of the watershed into sub-basins, followed by the extraction of topographic, morphometric, hydrological, and environmental parameters associated with flooding, and the identification of sensitive areas through game theory algorithms (Borda and Condorcet). The results indicate that the downstream areas of the Marahoué watershed, particularly those located along the main river course, are highly sensitive to flooding. Conversely, upstream areas, which are generally situated at higher altitudes, were classified within the low to very low flood risk categories.

Abstract: (french)
Chaque année en CÔTE D’IVOIRE, pendant la saison pluvieuse, plusieurs localités dont celles du bassin versant de la Marahoué sont sujettes à de fréquentes inondations occasionnant des pertes en vie humaines, des déplacements des populations et des dégâts matériels importants. Identifier les zones sensibles à ce phénomène est crucial pour la mise en œuvre des mesures préventives efficaces et durables. Ainsi cette étude vise donc à identifier les zones sensibles aux inondations dans le bassin versant de la Marahoué en utilisant les caractéristiques physiques et hydrologiques actuelles, extraites à partir des observations de télédétection en vue d’aider les décideurs dans leur projet de développement durable. L’approche méthodologique employée débute par la délimitation du bassin en sous bassin, ensuite l’extraction des paramètres topographiques, morphologiques, hydrologiques et environnementaux associés aux inondations et de l’identification des zones sensibles aux inondations via les algorithmes de la théorie du jeu (Borda et Condorcet). Les résultats obtenus, indiquent que les zones situées en aval du bassin versant de la Marahoué sont très sensibles aux inondations. À l’inverse, les zones situées en amont du bassin et qui sont dans la majorité à des altitudes plus élevées ont été classées dans les catégories de risque faible et très faible.
