Erosive processes and related hazards in the Coastal Zone.

The aim of this work, considering the evolution of the Adriatic Coastal area during the last 50 years, is to show how it is possible to face and contrast the erosive phenomena at the beginning of the event. A tardy intervention is, of course, more expensive without possibility to guarantee the final result. The selected area permits to consider different physiographic coastal units: the Venice lagoon, the Po river delta, the sandy littoral with the padan plain on the back and the cliff from Cattolica to Ancona.
