We present the multifractal analysis of several signals recorded at the valclusian karst spring of Prese Val, located in the Dolomities area northwest of Trento (Italy). The data analysed include water discharge, temperature and electrical conductivity. Both electrical conductivity and temperature, which mimic the spatial variability of hydraulic conductivity, show the signature of multifractality, while the water discharge shows a much more complex structure. We conclude that accurately recorded signals of electrical conductivity and temperature of spring water can be used for characterization of karst systems.

Abstract
We present the multifractal analysis of several signals recorded at the valclusian karst spring of Prese Val, located in the Dolomities area northwest of Trento (Italy). The data analysed include water discharge, temperature and electrical conductivity. Both electrical conductivity and temperature, which mimic the spatial variability of hydraulic conductivity, show the signature of multifractality, while the water discharge shows a much more complex structure. We conclude that accurately recorded signals of electrical conductivity and temperature of spring water can be used for characterization of karst systems.File in questo prodotto:
