  abstract = {{T}he potential response of flow regimes to future climate has crucial importance for a variety of practical applications, such as sustainable water management and ecological asset preservation. {F}or this study, multi-site investigations of alterations in flow regimes under projected climate change were performed for one of the largest watersheds in {M}orocco, the {B}ouregreg {W}atershed ({BW}). {F}uture daily streamflow was simulated using the eco-hydrological model {S}oil and {W}ater {A}ssessment {T}ool ({SWAT}) forced by climatic data from {CMIP}5 model outputs. {S}imulations were carried out for two periods: 2035?2050 (2040s), and 2085-2100 (2090s) under two emissions scenarios: {RCP}4.5 and {RCP}8.5. {F}uture streamflow regimes were examined in accordance with an {I}ndicators of {H}ydrologic {A}lteration ({IHA}) analysis, while being confronted with baseline flow data. {M}ean temperature has been predicted to increase by up to 2.79 degrees {C} in the 2090s ({RCP}8.5), and a higher variability in rainfall regime is expected. {T}he results indicate that, under future changes in climate patterns, flow regimes in {BW} will be altered. {H}owever, the extent of alteration will be reflected unevenly among the four streams of the study watershed. {T}he {IHA} analysis revealed that most of the river network will experience both a decrease in monthly flow magnitude (mostly in {N}ovember and {D}ecember), and an increase (dominantly in {F}ebruary and {M}arch) when compared to baseline. {T}he frequency of flash pulses, and the number of zero-flow days are also expected to increase. {M}ost of the projected alterations were estimated to become very significant in the 2090s under the {RCP}8.5 scenario. {T}he potential ecological implications were also analysed, and the most sensitive streams of {BW} were identified to guide local water planning and ecological preservation strategies.},
