  abstract = {{D}ue to climate and environmental changes, sub-{S}aharan {A}frica ({SSA}) has experienced several drought and flood events in recent decades with serious consequences on the economy of the sub-region. {I}n this context, the region needs to enhance its capacity in water resources management, based on both good knowledge of contemporary variations in river flows and reliable forecasts. {T}he objective of this article was to study the evolution of current and future (near (2022-2060) and distant (2061-2100)) flows in the {S}o'o {R}iver {B}asin ({SRB}) in {C}ameroon. {T}o achieve this, the {P}ettitt and modified {M}ann-{K}endall tests were used to analyze hydrometeorological time series in the basin. {T}he {S}oil and {W}ater {A}ssessment {T}ool ({SWAT}) model was used to simulate the future flows in the {SRB}. {T}he results obtained show that for the current period, the flows of the {S}o'o decrease due to the decrease in precipitation. {F}or future periods, a change in precipitation in line with the predictions of the {CCC}ma model will lead to a decrease in river discharge in the basin, except under the {RCP}8.5 scenario during the second period (2061-2100), where will note an increase compared to the historical period of approximately +4%. {R}esults from the {RCA}4 model project an increase in precipitation which will lead to an increase in river discharge by more than +50%, regardless of the period and the scenario considered. {A}n increase in discharges was noted in some cases despite a drop in rainfall, particularly in the case of discharges simulated for the second period (2061-2100) from the outputs of the {CCC}ma model. {T}his seems to be a consequence of the increase in impervious spaces, all the more the runoff increases during this period according to the model. {R}esults from this study could be used to enhance water resources management in the basin investigated and the region.},
