In the Dolomites mountain range, the most productive aquifers are found in porous valley-fill deposits, such as alluvial, glacial and other heterogeneous types of clastic sediments. These deposits store significant amounts of groundwater resources and are laterally bordered by steep carbonate reliefs, which in turn constitute fractured high-yielding aquifers. The talus cones and slopes at the base of the rock cliffs play the role of hydraulic connection between the fractured aquifers and the porous aquifers at the valley floor. This situation is very well represented in the San Lucano glacial valley system in the Dolomite Mountains (Italy), where average groundwater resources were estimated at approximately 2 m3/s. The hydrogeological data collected in this study allowed to identify the interaction between stream discharge and the saturated zone of the aquifers and to define apreliminary model of recharge and storage of the valley-fill aquifer.
