          Abstract

          En este trabajo, se analiza la composición isotópica del acuífero del Valle de San Luis Río Colorado en Sonora en conjunto con la concentración de cloruros del agua para determinar el origen del agua del subsuelo y establecer las causas del aumento de salinidad que se ha observado en el agua de riego. La mineralización del acuífero ha provocado un deterioro en la calidad del agua de esta agua. Se encontró que la composición isotópica deja ver un fraccionamiento como consecuencia de la evaporación rápida y la mezcla de aguas antiguas, infiltradas antes de la construcción del sistema de presas, con aguas recientes del Río Colorado, sometidas a un proceso de evaporación en los vasos de éstas. El análisis isotópico permitió establecer que el agua de los canales de riego más mineralizada aún no está presente en el acuífero.

          Translated abstract

          In this work, the isotopic composition and chloride concentration of San Luis Rio Colorado, Sonora, in Mexico were used to determine the origin of groundwater and to establish the salinity increase that has been observed in the irrigation water. The aquifer mineralization has provoked deterioration of this water. The isotopic composition showed a fractioning due to the sudden evaporation and the mixing of water percolated before the dam system, constructed upstream, with water infiltrated to the aquifer after evaporation in the reservoirs, these water types are known as old and recent, respectively. Unlike what it could be expected, the isotopic composition determined that mineralized water from irrigation channels is not yet present in the aquifer.

          Isotopic Variations in Meteoric Waters.

          H Craig (1961)
          The relationship between deuterium and oxygen-18 concentrations in natural meteoric waters from many parts of the world has been determined with a mass spectrometer. The isotopic enrichments, relative to ocean water, display a linear correlation over the entire range for waters which have not undergone excessive evaporation.
