En Alg\u00e9rie, avec la croissance d\u00e9mographique qui engendre l\u2019extension de l\u2019urbanisation, le d\u00e9veloppement de l\u2019industrie et du secteur agricole, il est n\u00e9cessaire de contr\u00f4ler la ressource en eau et de pr\u00e9dire les risques hydrologiques. Pour cela, il est important de connaitre la r\u00e9partition spatiale des pluies ainsi que les occurrences et intensit\u00e9s des \u00e9v\u00e8nements extr\u00eames. La relation intensit\u00e9-dur\u00e9e-fr\u00e9quence des maximas annuels de pr\u00e9cipitations issue d\u2019analyses statistiques des donn\u00e9es provenant des stations \u00e9quip\u00e9s de pluviom\u00e8tres \u00e0 augets basculaires, constitue aujourd\u2019hui un outil de\u00a0 r\u00e9f\u00e9rence pour les diff\u00e9rents utilisateurs. Ces outils sont convenablement utilis\u00e9s pour le dimensionnement des ouvrages hydrauliques en fonction de niveaux de risque ou d\u2019un niveau de service d\u00e9fini dans les diff\u00e9rents secteurs. L\u2019objectif de cette \u00e9tude est la caract\u00e9risation des r\u00e9gimes d\u2019averses en calculant les param\u00e8tres des courbes\u00a0: Intensit\u00e9-Dur\u00e9e-Fr\u00e9quence (IDF) en tout point de la r\u00e9gion Nord-Est de l\u2019Alg\u00e9rie pour diverses dur\u00e9es. Dans cette perspective, l’analyse statistique du maximum annuel r\u00e9v\u00e8le la pr\u00e9valence du choix de la loi des Valeurs Extr\u00eames G\u00e9n\u00e9ralis\u00e9es (GEV) sur son cas particulier Gumbel. Ce choix est important \u00a0puisqu\u2019il est directement li\u00e9 \u00e0 la s\u00e9curit\u00e9 des structures hydrauliques, \u00e0 l\u2019\u00e9tablissement des zones d\u2019inondations et \u00e0 l\u2019estimation des \u00e9v\u00e9nements extr\u00eames. Trois types d’\u00e9quations empiriques (Montana, Talbot et\u00a0 Keifer-Chu) ont \u00e9t\u00e9 utilis\u00e9s pour l\u2019\u00e9tablissement des courbes IDF des pr\u00e9cipitations et une \u00e9ventuelle comparaison dans le nord \u2013est Alg\u00e9rien.<\/p>\n
