This paper describes an original numerical model based on the energy flux applied by the wave motion to the coastline where the archaeological site of Egnathia (Apulian Adriatic coast) is located. The remnants of the ancient port are actually submerged. The program "Perfect Storm" uses the flux energy applied by the wind -induced wave actions to the shorelines. Sea storms occurred in the range 1951-2000 have been considered. The program allows to define, in consecutive steps, the model of energy obtained by each breaker wave to the shoreline The correlation among the model results, the geological set up, the amount of sediments moved by wave actions and currents, particularly during storms, and the chronological data of the archaeological structures allow the reconstruction of the morphological evolution of the area facing the ancient site. The amount of sediment transported is related to the climate conditions. The erosional and depositional phases have greatly controlled the geomorphological changes of the coastline and, as a consequence, also the town-planning choices during the life of the ancient town.

Abstract
This paper describes an original numerical model based on the energy flux applied by the wave motion to the coastline where the archaeological site of Egnathia (Apulian Adriatic coast) is located. The remnants of the ancient port are actually submerged. The program "Perfect Storm" uses the flux energy applied by the wind -induced wave actions to the shorelines. Sea storms occurred in the range 1951-2000 have been considered. The program allows to define, in consecutive steps, the model of energy obtained by each breaker wave to the shoreline The correlation among the model results, the geological set up, the amount of sediments moved by wave actions and currents, particularly during storms, and the chronological data of the archaeological structures allow the reconstruction of the morphological evolution of the area facing the ancient site. The amount of sediment transported is related to the climate conditions. The erosional and depositional phases have greatly controlled the geomorphological changes of the coastline and, as a consequence, also the town-planning choices during the life of the ancient town.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
