Traçage isotopique de la variabilité de la recharge des eaux souterraines

Abstract : Assessing the impact of current and future pressures on groundwater resources requires an assessment of recharge process. For these purposes, the isotopic tools, and more precisely the stable isotopes of the water molecule were used, as part of this work to understand the flow mechanisms within the unsaturated zone. A new analytical protocol allowing a better accuracy of pore water isotope measurements has been developed. A numerical calculation code taking into account the evolution of stable isotopes of water, from precipitation to groundwater, to estimate recharge has been established. Stable isotopes of the watermolecule have been shown to be powerful tools for constraining, by inverse modeling, the values of the hydrodynamic parameters needed to describe and predict water transport in the unsaturated zone at the profile scale and at the watershed scale.
