Abstract

The study of available and acquired data yielded the follow ing main results about groundwater flow system in the Acerno basin (Conca di Acerno), sometimes in disagreement with pre-vious studies: • two different groundwater flows have been identified: the first one in the carbonate bedrock (feeding the Ausino, Ausinetto and Avella spring group) and the other one in the river and lake sediments of the basin (feeding the Olevano spring and the lea-kages through the Tusciano riverbed; • a significant flow increase in the Tusciano river has been identified coming from the right bank of the river Tusciano; • analyses of chemical, isotopic and piezometric data showed that occurs an interaction between the two aquifers, and between these and the hydrographic network; • the limits of the groundwater basin feeding the Acerno spring group have been established more accurately, especially on the basis of the carried out hydrogeological balance. In fact, the area of the groundwater basin has been reduced and, to the east, brought to correspond with the position of an important tec-tonic lineament, located south of the Mt. Raia della Licina; • level with the river Tusciano, major tectonic lineaments act as a groundwater flow barrier toward south.
