On Friday 29 September 2023, the Researchers' Night event was held in the Cherubini Atrium of the Polytechnic University of Bari. In its stand, the Hydraulics group of the Polytechnic University of Bari exhibited a small wave channel similar to the physical models of the LIC - Coastal Engineering Laboratory. The system allows the erosive effect of the waves to be highlighted. The stand was completed by two posters that summarize some of the research activities of the Hydraulics group of the DICATECh of the Polytechnic University of Bari.
