Relation precipitation - spring discharge in the carbonate aquifer Tičnica
Metka Petrič - (27/1,1998)
The carbonate aquifer Tičnica near Idrija in western Slovenia was chosen as an experimental basin for study of relations between precipitation and spring discharges. Rainfall is the only source of recharge and there is no doubt that these relations exist. But a known fact that they are not simple and explicite and that some additional influences are important was confirmed by the comparison between measured daily values of precipitation and discharge and by calculating the correlation between these parameters. An important role of the previous precipitation expressed with the index of previous precipitation was shown by the research. Using this index the functional connection between precipitation and discharge was defined on the base of the comparison between the measured values.
