Analysis of historical cartography, wind direction data, orientation of Volturno River mouth and shoreline changes through time point out a series of morphological changes due both to natural and man-induced processes, which occurred along the Domitia coast (Litorale Domitio) since the second half of the 50s. Meteorological time series analysis showed evidence of a change in wind frequency and direction before and after the second half of the 70s, with almost complete disappearance of wind calm periods. Particularly, after 1975, the angle of wave attack had changed and intensity and frequency increased, thus accelerating coastal erosion in some areas. The morphological response to these environmental changes, likely due to global warming and short climatic crises interacting with anthropic modifications of landscape, resulted in different orientation of the Volturno River mouth which rotated from NW (between the 50s and 70s) to SW (from the mid-70s until the present). Moreover, the NW-SE littoral drift caused a clockwise rotation of the entire coastal segment with fulcrum pole close to the river mouth, since the 50s. These findings may allow the assessment of land-use scenarios tuned with evolution trends in order to properly address planning of these reactive and dynamic landscapes.
