Abstract

To mitigate coastal erosion and harbors siltation several selective strategies are currently available. Among the traditional solutions, an innovative device, i.e. the “ejector”, characterized by low operative costs, no environmental impact and able to simultaneously counteract both phenomena, was designed and experimentally tested in laboratory and in field by the University of Bologna starting from 2002. Based on the Venturi’s effect, in fact, the device moves sediments from their original position into the basin to another desired position ensuring many advantages such as, but not limited to i) a continuous 24/7 operation, ii) no environmental impact, iii) low operating costs, and iv) benefits to local economies maintaining harbors able to be sailed for all the year. After the technical description of the technology, the demo plant designed and built in the harbor of Cervia (Italy) is completely analyzed.
