  abstract = {{T}his study aims to estimate the groundwater storage change of hard rock aquifers in the face of change. {F}or this, the approach developed consisted initially in the implementation of 5 {M}agnetic {R}esonance {S}oundings ({MRS}) around the observation wells realized and monitored from 2014 to 2015 in the {S}anon experimental site. {I}n a second step, we determined the storage change using the {MRS} data and the water table fluctuation method. {T}he {MRS} data show that the water content varies spatially from 4.5 to 1.3%. {T}he maximum value is recorded at the central valley where a piezometric dome is observed. {T}he specific yield varies from 2.4% in the central valley to 1.3% at the outlet. {T}he renewed water resource is estimated at 116 mm in the central valley and 32 mm at the outlet, which corresponds respectively to 13 and 3% of the annual rainfall. {T}he renewed water resource is consistent with the annual recharge. {T}hus, the combination of the {MRS} geophysical approach and water table fluctuation method is an efficient, fast and cheaper (compared with long-term pumping test) tool for the estimation of groundwater storage changes.},
