  abstract = {{R}adiocarbon decay is rarely used to assess the residence time of modern groundwater due to the low resolution of its long half-life in comparison to the expected range of ages. {N}onetheless, the modern {C}-14 peak induced by the nuclear bomb tests traces efficiently the impacts of recent human activities on groundwater recharge, as well as for tritium. {A} simple lumped parameter model ({LPM}) was implemented in order to assess the interest of {C}-14 and {H}-3 nuclear peaks in a highly anthropized aquifer system of southeastern {S}pain under intense agricultural development. {I}t required i) to assess a correction factor for modern {C}-14 activities and ii) to reconstruct the {H}-3 recharge input function, affected by irrigation. {I}n such a complex hydrogeological context, an exponential model did not provide satisfying results for all samples. {A} better solution was reached by taking into account the qualitative recent variation of the recharge rates into a combined exponential flow and piston flow model. {A}part from presenting an uncommon approach for {C}-14 dating of modern groundwater, this study highlights the need of considering not only the variation of the tracer but also the variability of recharge rates in {LPM}s.},
