Abstract

Beach nourishments protected by submerged sand bag barriers have been largely used in Emilia Romagna (Italy), whose low and sandy coast faces the relatively mild Northern Adriatic Sea. The paper, after a brief description of the eight projects of this type realised in the last 25 years along the Emilia Romagna littoral, details the case study of Riccione Southern beach. The performance of the defence is described by means of cross-shore profiles, bathymetries, collection of sediment samples, underwater pictures, monitoring of environmental conditions and performed maintenance. The combined analysis of the available data suggests that the sand bag barrier may stabilise the position of the natural sandy bar and ultimately the beach profile.
