Sažetak
Statistical analyses have been carried out on a long-term (1878-2004) series of mean annual discharges of the famous karst spring Fontaine de Vaucluse (France) and its catchment annual rainfall. The Fontaine de Vaucluse is a typical ascending karst spring situated in the south-eastern region of France. The spring has an average discharge of 23.3 m3/s. The average annual rainfall is 1096 mm. Its catchment area covers 1130 km2. Using the rescaled adjusted partial sums (RAPS) method it is established existence of next five statistically significant different sub-series: 1) 1878-1910: 2) 1911-1941 ; 3) 1942-1959: 4) 1960-1964 ; 5) 1965-2004. The different spring discharge characteristics during long lasting period (1878-2004) can be caused by natural climatic variations, by anthropogenic influences, and possibly by climate changes. In this moment should be stressed that objective and scientifically based reasons for different hydrological behaviour in five time sub-periods did not found.
