The Effect of the Seawater Intrusion on the Robinzon Coastal Spring

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