Abstract

Determining the content of O 18 and deuterium in the groundwater at the southern edge of the Sierra de Gador, between October 1991 and March 1993, has enabled identification of the flow system of the waters, the recharge and mixing processes and the possible mechanisms of salinization. Analysis of the precipitation indicates the dominant source and direction of the air masses. The local meteoric water line that is established indicates a primarily Mediterranean origin for the precipitation recharging the aquifers. The variation of O 18 content with altitude enables an estimation of the principle recharge area, which corresponds to a zone between 1200 and 1800 m a.s.l.
