  abstract = {{T}he aquifer of the semi-arid {K}airouan plain has been exploited for decades to supply the growing irrigated agriculture and the need of drinking water. {I}n parallel, the major hydraulic works drastically changed the natural groundwater recharge processes. {T}he continuous groundwater level drop observed since the 1970s naturally raises the question of groundwater storage sustainability. {T}o date, hydrogeological studies focused on groundwater fluxes, but the total amount of groundwater stored in the aquifer system has never been fully estimated. {T}his is the purpose of the present paper. {A} complete database of all available geological, hydrogeological and geophysical data was created to build a 3{D} lithology model. {T}hen, the lithological units were combined with the hydraulic properties to estimate the groundwater storage. {O}ver the 700 km(2) of the modelled area, the estimated storage in 2013 was around 18 x 10(9) m(3) (equivalent to 80 times the annual consumption of 2010) with a highly variable spatial distribution. {I}n 45 years (1968-2013), 12% of the amount of groundwater stored in the aquifer has been depleted. {A}ccording to these results, individual farms will face strong regional disparities for their access to groundwater in the near future.},
