  abstract = {{T}he {T}rarza aquifer extends over about 40 000 km(2) in southwestern {M}auritania, between the {S}enegal {R}iver in the south, the {A}tlantic {O}cean in the west and the {M}auritanides metamorphic chain in the north and east. {T}he {T}rarza aquifer lies in {C}ontinental {T}erminal and {Q}uaternary sediments. {T}he field investigations conducted between 2010 and 2012 significantly added to the few older measurements. {T}he hydrodynamic and geochemical approaches showed that in this semi-arid area, the groundwater dynamics is influenced by many environmental changes, past and present (from {Q}uaternary transgressions to the various dams regulating the {S}enegal {R}iver). {G}roundwater is mainly recharged by lateral infiltration of surface water of the {S}enegal {R}iver, and to a lesser extent, by rainfall infiltration. {G}roundwater mineralization is controlled by water-rock interactions with silicates and alumino-silicate minerals and is locally influenced by marine water resulting from past {Q}uaternary transgressions. {E}vaporation strongly affects surface waters before and during their infiltration. {V}ery preliminary calculations suggest an annual recharge of less than or equal to 5% of precipitation, i.e. about 5 to 10 mm.},
