Historical shorelines spanning from 1954 up to 2018 have been reconstructed: aerial and satellite images have been used to digitize the 130 km long regional shoreline.
An ad hock methodology has been defined. It is aimed to address the main features of shoreline evolution by defining a series of morphological units, from the Northern littoral of Martinsicuro down to the Southern littoral of the San Salvo municipality.
Basically, the methodology is aimed to gain insight on the mean annual shoreline retreat/advance for each time window of about twenty years (1956-1976, 1976-1997, 1997-2018). By employing the well-known “one-line equation” and the estimation of the closure depth, the shoreline evolution will be used also to assess the longitudinal sediment transport responsible of the morphodynamical response of the regional sandy beaches to incoming waves.
The results are coming…
