Abstract
La principal descarga del acuífero de Sierra Gorda se produce en su
borde norte. La mayor parte de los manantiales asociados se sitúan en la
margen izquierda del río Genil en el entorno de Loja (Granada), pero existen
también manantiales en la margen derecha, como el manantial del Frontil,
en los que la procedencia del agua subterránea es controvertida. Los
datos físico-químicos provenientes de la red de control de calidad del IGME,
tomados entre los años 1991 y 2001, aportan argumentos a favor de la relación
hidrogeológica entre el acuífero de Sierra Gorda y los manantiales de
la margen derecha del río Genil, lo que implicaría el paso del agua subterránea
bajo dicho río sin que se produzcan mezclas con las aguas superficiales.
Se incluye también información de una campaña de muestreo realizada
en el otoño de 2011 que incide en el mismo sentido
The main discharge Sierra Gorda aquifer occurs in the northern boundary. Most of the springs related to the aquifer are on the left bank of the Genil river, in the vicinity of Loja (Granada), but there are springs on the right bank, as the spring of Frontil, where the origin of groundwater is contested. The arguments for the hydrogeological relation between the Sierra Gorda aquifer and springs on the right bank of the river Genil are provided by the physico-chemical data from the Geological Survey of Spain network quality control, taken between 1991 and 2001. This question involves the passage of groundwater under the river without producing mixtures with surface water. It also includes information from a sampling campaign in the autumn of 2011 that falls in the same direction
