Investigación del funcionamiento hidrogeológico del acuífero carbonatado drenado por el manantial de Villanueva del Rosario (Alta Cadena, Málaga) a partir de un ensayo de trazadores

A multi-tracer test was done in the Alta Cadena and Los Tajos mountains range (Malaga province, southern Spain) in order to delimitate the aquifer system drianed by Villanueva del Rosario spring and to precise its hidrogeological behaviour. The results show a partitioning of the carbonate outcrops in different aquifer systems. The system drained by Villanueva del Rosario exhibits clear a karstic behaviour with flow velocities above 200 m/h. The karst conduits and the groundwater flow path in this system are determined by ENE-WSW folds and thrust, and transverse fractures.
