Le Fleuve Niger prend sa source dans les plateaux du Fouta-Djalon en GuinĂ©e et traverse successivement le Mali, le Niger, le BĂ©nin et le Nigeria oĂč il se jette dans l’OcĂ©an Atlantique aprĂšs un parcourt d’environ 4200km. C’est le troisiĂšme plus long fleuve d’Afrique, le 14Ăšme du monde et le 9Ăšme du point de vue de la taille de son bassin versant.  Son bassin actif couvre une superficie d’environ 1,5 millions km2 que se partagent les neuf (9) pays regroupĂ©s au sein de l’AutoritĂ© du Bassin du Niger : le BĂ©nin, le Burkina Faso, le Cameroun, la CĂŽte d’Ivoire, la GuinĂ©e, le Mali, le Niger, le Nigeria et le Tchad. La BĂ©nouĂ© qui prend sa source au Tchad avant de traverser le Cameroun pour rejoindre le cours principal du Niger Ă  Lokoja au Nigeria est son affluent le plus important.

L’annĂ©e hydrologique du fleuve Niger dĂ©bute le premier juin et se termine le 31 mai de l’annĂ©e suivante.

Ce bilan hydrologique du fleuve Niger pour cette annĂ©e hydrologique 2014/2015 fait l’analyse de la situation des Ă©coulements aux stations reprĂ©sentatives des diffĂ©rente sous bassins : Koulikoro (Mali) pour le Niger SupĂ©rieur,  Dire (Mali) pour le Delta IntĂ©rieur ;  Niamey (Niger) pour le Niger Moyen et Lokoja (Nigeria) pour le Niger InfĂ©rieur.

Le suivi des Ă©coulements au cours de l’annĂ©e hydrologique 2014-2015 a Ă©tĂ© assurĂ© dans le cadre des activitĂ©s du projet GIRE2/Volet-Niger-HYCOS Ă  partir d’une centaine de stations hydromĂ©triques Ă©quipĂ©es de plates-formes de collecte de donnĂ©es(PCD) de type Satlink, des Liminigraphes Ă©lectroniques avec ou sans  transmission GSM, de radio BLU ou de simples Ă©chelles limnimĂ©triques suivies par un observateur qui transmet les donnĂ©es aux services hydrologiques nationaux et au Centre RĂ©gional du Projet par GSM, Internet et les autres moyens classique de collĂšte de donnĂ©es.

The hydrological year 2014/2015 ended in May 2015 with low flow situation observed at the entire Niger River basin. The flows were supported during this period of recession by the releases of dams Sélingué in Mali, Lagdo Cameroon, Kainji, Jebba and Shiroro Nigeria

The flow analysis situation was carried out by dividing the basin into four sub-catchments also represented with reference gauging stations as follows: Upper Niger at Koulikoro (Mali), Inland Delta at Dire (Mali), Middle Niger in Niamey (Niger) and Lower Niger at Lokoja (Nigeria)
