The Cave of Canalobre, located in the west middle of the Alicante province, is one of the most visited cave
in Comunidad Valenciana. During the last years some drip water samples have been collected. The analytical
results have allowed us the physico-chemical characterization of the waters. Use of principal components
analysis (PCA) and a study of hydrodynamic equilibria have allowed us to stablish that the proper ties and
composition of these waters depend on both dissolution proccess of the rock during the downward
passage and climatic concentration in the soil of the components dissolved in the rainwater
