In this case, the deepest submerged palaeocoast and the present-day coast show high values of fractal dimension, close to those of the British coast (Df = 1.25), hence indicating morphological control connected to the postglacial eustatic oscillations to which, in recent and historical times, the prevailing modelling caused by coastal dynamic processes has been added.

Abstract

Application of fractal geometry on emerged and submerged coastlines of the Sorrento Peninsula (Tyrrhenian Sea) and of Porto Cesàreo (Ionian Sea), which have different geological and geomorphological features, has shed light on the morphological processes closely connected to their evolution. The results of the fractal dimension analysed along the Sorrento Peninsula, with its more or less rectilinear physiography, show a gradual increment of values coming from the submerged areas towards the present-day coastline. It has thus experienced the overlapping of the modelling processes of the sea on tectonic processes, while the present-day coastline shows the effects of erosive wave action. The coastal area of Porto Cesàreo, characterized by a more irregular present-day physiography, shows values of the fractal dimension of the submerged palaeocoast close to unity, suggesting that the morphological evolutionary processes might be the effects of Pleistocene tectonics. In this case, the deepest submerged palaeocoast and the present-day coast show high values of fractal dimension, close to those of the British coast (Df = 1.25), hence indicating morphological control connected to the postglacial eustatic oscillations to which, in recent and historical times, the prevailing modelling caused by coastal dynamic processes has been added.
