    Les catastrophes hydriques naturelles touchant les territoires urbains se multiplient et la vulnérabilité des villes aux risques hydriques augmente. L'article propose une analyse de ce phénomène dans les mégapoles. La démarche est exploratoire et débute avec la construction d'une base de données renseignant les 595 mégapoles existantes dans le monde. Ensuite, une analyse multifactorielle détermine les traits caractéristiques de ces mégapoles. Au final, la recherche identifie trois composantes structurelles des mégapoles (maturité, anthropisation et centralité) puis les corrèle avec des variables de risques. Ainsi, elle distingue des groupes de villes selon leur structure et des facteurs de vulnérabilité.
