Sažetak
The Robinzon Spring, located 70 m from the seacoast, is a freshwater, perennial spring with a yield ranging from the maximum 2 m3 /s to the minimum 0.165 m3 /s. The spring occurs at the contact between per- meable carbonate rocks and impermeable flysch deposits. This con- tact is deeply weathered, eroded and submerged below sea level. Such conditions emphasize the delicate relationship between the fresh- and seawater. The objective of the study was to shed more light on the hydrogeological setting of the spring’ s underground recharge area by means of borehole measurements and preexisting knowledge about the dynamics of the fresh- and seawater acquired from similar cases. The spring’ s underground area is divided into three zones: (i) zone of good water circulation (rockfall material and fractured dolomite), (ii) zone of poor water circulation (massive dolomites), and (iii) zone of ‘ ’ trapped’ ’ water (contact between the dolomite and flysch deposits).
