The assessment of the response time a karst aquifer is an important step towards development conceptual models from which tools for water resources planning and management could be applied. aim this work to evaluate applicability joint use statistical time-lag evaluation dye tracer tests techniques with double objective: 1) on hydrogeological functioning that include duality in recharge processes, as well particularities preferential drainage flowpaths respect global aquifers; 2) establish reference frame foresee enough anticipation potential affections derived concentrated springs, required creation quality monitoring networks early warning systems pollution. In Ubrique (southern Spain), empirical relationships between intensity (I) rainfall events (recharge) (T) observed springs draining have been quantified. establishment curve (I-T) constitutes reliable tool prediction (intended urban supply) events. On other hand, comparison values drawn I-T curve, characteristic each spring, those three tests, has allowed further advances understanding influence system behavior achieved.
