Caratteri idrogeologici dell'acquifero della piana costiera di Metaponto (Basilicata)

The examined area extends between the mouths of Cavone and Bradano rivers, along Ionian coast. Stratigraphic settlements of alluvial and marine deposits, which constitute the aquifer, have been established. On the ground of these results, the different flow modes of water bed, the aquifer levels continuity and thickness have been examined. Besides, waterproof substratum top patterns have been determined. Finally, through the analysis of all hydrological and hydrogeological data collected, it was possible to clear up the complex relations among underground water bed, hydrographical ne1 and sea. So it was possible to define all required conditions to accomplish the calibration of a numerica1 mode1 of underground water flow.
