The Mount Mia massif is located in the eastern side of the Friuli Venezia Giulia Region, across the border between Italy and Slovenia. It is an important karst hydrostructure bounded in the N, E and S by the Natisone River (Figure 1). Several springs are emerging at the toe of the massif mainly in the south-eastern side along the river. The two main springs, Poiana and Tologu, are tapped for the Cividale town water supply. The aim of the present paper is to assess the spring recharge area, its potentialities and vulnerabilities in order to quantify a possible increase withdrawal for the water supply.
