Description

Seasonal floodplains, which can reach 90000km² in the Lake Chad Basin, play an important role in its ecology, in the services provided to societies and in the regulation of the water supplies to the Lake Chad. As such, they are an important element in water management.

The floodplains near Lake Chad, such as the Great Yaéré floodplain between Chari and Logone, the Massenya plain, the Salamat in the Chari basin, the Hadejia-Nguru floodplains on the Komadugu-Yobe in Nigeria near the border with Niger or the lower Ngadda, Yedseram and El Beïd rivers in Nigeria, are almost completely dry during part of the year.

Figure 1 presents the estimated minimum, maximum and average flooding extent of the lower Logone (Yaéré/Naga plain) based on MODIS time series 2000-2014 analysis in the framework of the "Sustainable Groundwater Management Project" of BGR with LCBC.
