Abstract

In 1963, the Grande Motte marina study began on a scale model built at Sète near the site. The main conclusion of the study was that the designed harbour would not suffer heavy difficulties due to littoral sand transports. More than twenty years after the harbour has been built, it appeared usefull to compare the model anticipations and the on site observed events. The study is succesfull as far as sediment movements are concerned; some imperfections on detail behaviour of the scale model are instructive. The coastal protection built on the eastern side of the harbour, with one groin and three breakwaters, is also described in the paper.
