  abstract = {{S}tudy region: {S}enegal {R}iver {B}asin in {W}est {A}frica. {S}tudy focus: {T}his work aimed to assess reference evapotranspiration ({ET}0) trends and its sensitivity to climate variables on the period 2036-2065 in the {S}enegal {R}iver basin. {S}even {G}eneral {C}irculation {M}odels ({GCM}s) and seven {R}egional {C}limate {M}odels ({RCM}s) of the {CMIP}5 project were used under the scenarios {RCP}4.5 and {RCP}8.5. {T}he performance of {GCM}s and {RCM}s was first evaluated by comparing their outputs with the reanalyses data. {T}he change of {ET}0 is determined between the periods 1971-2000 and 2036-2065. {A} sensitivity coefficient was calculated to analyze the influence of climatic variables on {ET}0. {F}inally, the {M}ann {K}endall test and {S}en slope were used to detect future trends in {ET}0 and climate variables. {N}ew hydrological insights for the region: {I}t was found that {RCM}s were here more robust than {GCM}s in estimating reference evapotranspiration over the period 1984-2000. {C}ompared to the period 1971-2000, the {RCM}s show that {ET}0 will increase by 14-293 mm under {RCP}4.5 and by 55-387 mm under {RCP}8.5 according to the climatic zones. {T}he maximum values are observed in {S}ahelian zone and the minimum one in {G}uinean area. {T}he sensitivity analysis shows that {ET}0 is more sensitive to relative humidity, maximum temperature and solar radiation. {T}he trend analysis reveals, generally, a significant increase in {ET}0 and in maximum and minimum temperatures in the period 2036-2065 under the {RCP}4.5 and {RCP}8.5 scenarios. {T}his means that {ET}0 will not be stationary and may continue to increase after 2065 because of the increase of temperature.},
