  abstract = {{S}tudy {R}egion: {C}hari-{L}ogone {R}iver basin, {L}ake {C}had basin. {S}tudy {F}ocus: {T}he objective of this study was to better understand the hydrological functioning of the {C}hari-{L}ogone basin under the effect of the high variability of rainfall which has affected the {S}ahel during the last sixty years. {T}he study is based on hydro-climatic data for the period between 1960 and 2015 obtained from the national and international institutions. {T}his work based on the following steps: 1) {A}verage hydrological balances were estimated for different geographical areas, to identify the most productive parts of the basin. 2) {T}he rainfall-runoff relation was compared for the wettest and driest decades of the study period, to identify the areas that contribute most to the amplification of the hydrological response to variations in rainfall. 3) {T}he long-term period stability of the rainfall-runoff relation was evaluated for climatic conditions close to the average situation, in order to detect potential evidence of the anthropogenic impact. {N}ew {H}ydrologic {I}nsights for the {R}egion: {D}uring the period 1960-2015, the average water flow in the {C}hari-{L}ogone basin (42 mm/year) represented only 5% of precipitation. {B}etween the two climatically most contrasted wet (1960-1971) and dry (1982-1997) periods, the average flow differed by 75 % against a decrease of 15 % of precipitation. {O}ur hydroclimatic data show no clearly detectable evidence of an anthropogenic impact responsible for a decrease in flows or a modification of the hydrological regime in the {C}hari-{L}ogone basin.},
