Publikováno v: Hydrology and Earth System Sciences, Vol 20, Iss 7, Pp 2841-2859 (2016)

Since 1950, the Niger River basin has gone through three main climatic periods: a wet period (1950–1960), an extended drought (1970–1980) and since 1990 a recent partial recovery of annual rainfall. Hydrological changes co-occur with these rainfa
