The study of the flow paths shows the different hydrogeochemical conditions of carbonate materials in the
southern edge of Sierra de Gádor. The study and modelling have consisted on the comparison of the
saturation indexes evolution along the supposed flow path and the calculation of the mass balance
(dissolution-precipitation processes of different phases) among the different wells analysed. The combination
between the calculations of the mass transfer and the groundwater flow time allows to establish the
apparent velocity of dissolution with respect to several minerals (calcite, dolomite and gypsum)
