Distribucion espacial de isótopos estables (18O y 2H): vínculos entre precipitaciones, aguas superficiales y subterráneas e incidencia geomorfológica en una planicie mal drenada, Córdoba (Argentina)
Resumen
El objetivo de este estudio es establecer las relaciones entre la distribución espacial de la composición isotópica de las aguas superficiales y subterráneas con los factores geomorfológicos y las precipitaciones, utilizando técnicas isotópicas, en la zona urbana y rural de Canals, ubicada en un sector de la Llanura Pampeana, en la provincia de Córdoba, Argentina. El drenaje en la región es moderadamente impedido, destacándose la presencia de dunas y cubetas de deflación con lagunas. El acuífero libre presente está compuesto por arenas finas y muy finas. Las interconexiones hidráulicas fueron evaluadas mediante metodología hidrogeológica convencional y análisis de isótopos estables del agua (δ²H y δ¹⁸O). La hidrodinámica y la geoquímica indican que el acuífero presenta flujos de diferentes jerarquías, tanto locales como intermedios procedentes de aguas arriba. Las relaciones hidráulicas, geoquímicas e isotópicas están influenciadas por factores morfolitológicos, la profundidad del nivel freático y la actividad antrópica (sistemas de saneamiento in situ, agricultura y ganadería intensiva, entre otras). Los resultados isotópicos sugieren agua de origen local, con recarga principalmente durante las estaciones de verano y otoño y en menor medida en primavera, además de llegada de flujos de mayor jerarquía procedente de tierras más altas ubicadas al Oeste de la localidad fuera del área de estudio.
