EnglishThe 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. | |
