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 l'Ouémé au Bénin sont :
  • Ouémé at Bonou period 1948-1996 code 1114500107
  • Ouémé at Domé period 1952-1991 code 1114501005
  • Ouémé at Hetin Sota period 1948-1986 code 1114500113
  • Ouémé at Kaboua period 1951-1992 code 1114501103
  • Ouémé at Pont de Bétérou period 1952-1998 code 1114500105
  • Ouémé at Pont de Savé period 1951-1998 code 1114500119
  • Ouémé at Sagon period 1951-1987 code 1114500117
  • Ouémé at Savalou Déversoir period 1952-1985 code 1114503303
  • Ouémé at So Awa period 1951-1980 code 1114501206
  • Ouémé at Vossa period 1953-1986 code 1114501302
    • 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)

    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.
