  abstract = {{I}n the {M}erguellil valley (central {T}unisia), the {E}l {H}aouareb {D}am is constructed over a karstic sill. {I}ts construction completely changed the surface water and groundwater flows. {N}ow water massively infiltrates under the dam reservoir and mixes with the {A}in {E}l {B}eidha groundwater, from the upper catchment, and feeds the karst that later flows into the great alluvial aquifer in the {K}airouan {P}lain. {T}he isotopic analysis ({H}-2, {H}-3, {O}-18) of these different compartments gives a clearer idea of the regional water budget and significantly supplements the available hydrodynamic information. {F}or the sampled times, contribution of dam water to the karst varies between 21 and 66%; it increases with the reservoir water level. {W}ater infiltrated since the dam construction has greatly "contaminated" the first 7 km of the alluvial water table where traces of the previous recharge process (in-wadi infiltration of heavy floods) are still observable.},
