The shoreline evolution is an important issue in the knowledge of the beach behaviors, especially the shoreline cross-shore retreat or advance following sea storms. The topic has been studied in the past using empirical, numerical and analytical approaches. The paper presents a quantification of the cross-shore shoreline behaviors, corresponding to sea storms; the aim is achieved with the use of video derived shoreline position in Lido di Dante, where an ARGUS station has been operating since the year 2003. The measured cross-shore behaviors of the shoreline are compared with the ones estimated with the empirical model developed by Dong and Chen (1999) (Coastal Eng. 36. pp 246 – 261). The model was selected among a large quantity of models available due to its simplicity. This comparison allows to analyze critically advantages and disadvantages of the model and will permit in the future to calibrate a new model which could overcome the limitations assigned to the Dong and Chen (1999) model.

Abstract
The shoreline evolution is an important issue in the knowledge of the beach behaviors, especially the shoreline cross-shore retreat or advance following sea storms. The topic has been studied in the past using empirical, numerical and analytical approaches. The paper presents a quantification of the cross-shore shoreline behaviors, corresponding to sea storms; the aim is achieved with the use of video derived shoreline position in Lido di Dante, where an ARGUS station has been operating since the year 2003. The measured cross-shore behaviors of the shoreline are compared with the ones estimated with the empirical model developed by Dong and Chen (1999) (Coastal Eng. 36. pp 246 – 261). The model was selected among a large quantity of models available due to its simplicity. This comparison allows to analyze critically advantages and disadvantages of the model and will permit in the future to calibrate a new model which could overcome the limitations assigned to the Dong and Chen (1999) model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
