Description
Jeux de données SIG et débits mensuels par bassins versants d'Afrique de l'Ouest et Centrale. Les fichiers fournis sont des fichiers d'entrée des modèles (couches vecteur SIG au format shapefile) des bassins versants constituées à partir des données cartographiques des 356 bassins référencés sous la base SIEREM. http://www.hydrosciences.fr/sierem/produits/produits/livret.pdf
Les principales stations de mesures hydrométriques et leur période de débits mensuels observés du bassin versant de la Komadougou Yobé au Niger sont :
  • Komadougou Yobe at Bagara Diffa period 1957-1976 code 1324000103
  • Komadougou Yobe at Gueskérou period 1957-1975 code 1324000106
    • Tous les fichiers de données sont au format ArcGIS (shapefiles) :
    • les contours des bassins versants sont représentés par des polygones
    • le réseau hydrographique du bassin versant est représenté linéairement
    Pour chaque station une chronique de débits mensuels issus du système d'informations SIEREM complète le jeu de données (format texte) (2024-09-01)

    • Notes Le système d'informations environnementales SIE SIEREM est constitué d'observations hydrométéorologiques couplées avec des données spatialisées, des contours de bassins versants des fleuves d'Afrique, des documents historiques concernant le continent africain. L’unité mixte de recherche HSM - HydroSciences Montpellier est dépositaire du fonds historique de données hérité entre autre du fichier « historique » de l’ORSTOM (IRD) pour l’Afrique de l’Ouest et Centrale. Des données complémentaires ont été collectées de plusieurs sources : les Services Nationaux Africains, le programme FRIEND de l’UNESCO (Programme Hydrologique International) et ses déclinaisons régionales et bases de données associées. Enfin, ces données ont été complétées localement lors de programmes de recherche pluridisciplinaires s’intéressant à l’analyse statistique des événements extrêmes, leur prévision et la compréhension des phénomènes associés. La gestion et l'administration de bases de données dans la thématique zone critique répondent à plusieurs objectifs, comme le suivi de bassins versants visant à comprendre les processus hydrologiques, la modélisation pour reconstituer sur le long terme des chroniques de champs de pluie, des écoulements en rivière, et prévoir leur évolution à différentes échelles.
