We present the multifractal analysis of several signals recorded at the valclusian karstic spring of Prese val, located in the Dolomities area NW of Trento (Italy). The data analysed include water discharge, temperature and electric conductivity. Both electric conductivity and temperature, which mimic the spatial variability of hydraulic conductivity, show the signature of multifractality with increments distributed as a Lévy stable probability distribution. This is not the case for the water discharge. We conclude that accurately recorded signals of electric 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 karstic spring of Prese val, located in the Dolomities area NW of Trento (Italy). The data analysed include water discharge, temperature and electric conductivity. Both electric conductivity and temperature, which mimic the spatial variability of hydraulic conductivity, show the signature of multifractality with increments distributed as a Lévy stable probability distribution. This is not the case for the water discharge. We conclude that accurately recorded signals of electric conductivity and temperature of spring water can be used for characterization of karst systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
