Water circulation in coastal marine areas - case studies

Taking into account the difficulty of water circulation within the marinas and over the defence works, an integration to the enquiries to support the technical solutions found is required, by means of the implementation of experimental tests of a threedimensional physical model. The aim of the experimental survey carried out in the wave system basin of the University of Campania "Luigi Vanvitelli" was that of assessing the water circulation intensity behind the works of Salerno and Ischitella coast and inside Fiumicino port, Manfredonia port and Castelvolturno port. Due to the remarkable linear development of the works, their behavior was studied through the realization of a Froude scale model. The water circulation over the defense works was evaluated with reference to the storms, while inside marina with reference to the action of the jet mixers. The results of tests show that water circulation is ensured by jet mixer inside marina and by storms behind defence works.
