  abstract = {{T}he significantly high water stress affecting {M}orocco during the past decades was an impact of drought and overexploitation of water resources. {T}herefore, assessment of these resources for better water management is a necessity. {I}n our context, the {H}igh and {M}iddle {A}tlas {M}ountains are the main contributors of downstream feeding within the country. {T}he objective of this study is to assess rainfall and snowmelt runoff supplying groundwater of the aforementioned regions using the stable isotopes approach. {S}ampling campaigns and chemical and isotopic analyses were carried out in the {O}urika and {H}igh {O}um {E}r-{R}biaa sub-catchments, belonging to the great {T}ensift and the {O}um {E}r-{R}biaa basins respectively. {T}he snowmelt sampling in the {O}urika basin was effectuated in two ways: the polyvinyl chloride snow cover boring and the passive capillary samples. {T}he isotopic data of the {O}urika basin allows estimating a recharge altitude between 2000 and 3000 m, following an altitudinal gradient of 0.27 parts per thousand/100m. {T}he contribution of rainfall and snowmelt in groundwater recharge using the isotopic mass balance model suggests a snowmelt recharge rate of 47% while rainfall supplies about 53%. {T}he isotopic preliminary results from the {HOER} catchment indicates that all samples are close to global and local water meteoric lines suggesting their common origin from the {A}tlantic air masses, and recharge altitude varies between 1600 and 2900 m according to a gradient of 0.27 parts per thousand/100 m. {U}ltimately, this study reveals the usefulness of environmental tracers to assess the endmembers contributions (snow and rain) to groundwater recharge at the catchment scale.},
