The main purpose of this work is to characterize coastal dunes of the Province of Ravenna (Italy) and to reconstruct their recent evolution (last 50 years) using available aerial imageries. The coastal area from Porto Garibaldi to Cervia in the years 1954, 1972, 1988, 1994 and 2000 has been considered. A GIS has been created to evaluate the variations in the coastal dunes extension. Some phyto-sociological surveys have been carried out on some of the most representative dunes in the area. Species diversity and the degree of naturalness of each dune have been calculated and the present vegetation has been compared to the vegetation in the Seventies. In two case-studies (Marina di Ravenna’s dune and the southern part of the Lido di Classe’s dune), a simulation using FDM (Fugitive Dust Model) has been carried out, with the purpose of evaluating dunes hypothetical natural geomorphological evolution. Ravenna’s coast and dunes belong to a very developed area where tourism represents a huge economical income. It is thus necessary to identify the best intervention for the protection of the beach-dune system for such an impacted coast.

Abstract
The main purpose of this work is to characterize coastal dunes of the Province of Ravenna (Italy) and to reconstruct their recent evolution (last 50 years) using available aerial imageries. The coastal area from Porto Garibaldi to Cervia in the years 1954, 1972, 1988, 1994 and 2000 has been considered. A GIS has been created to evaluate the variations in the coastal dunes extension. Some phyto-sociological surveys have been carried out on some of the most representative dunes in the area. Species diversity and the degree of naturalness of each dune have been calculated and the present vegetation has been compared to the vegetation in the Seventies. In two case-studies (Marina di Ravenna’s dune and the southern part of the Lido di Classe’s dune), a simulation using FDM (Fugitive Dust Model) has been carried out, with the purpose of evaluating dunes hypothetical natural geomorphological evolution. Ravenna’s coast and dunes belong to a very developed area where tourism represents a huge economical income. It is thus necessary to identify the best intervention for the protection of the beach-dune system for such an impacted coast.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
