The Upper Scrivia Valley in the Ligurian Apennines is characterized by a large-scale landslides area wider than regional and national averages. A number of deep-seated gravitational slope deformations (DSGSDs) were detected and mapped on the basis of geomorphological constraints such as closed depressions, trenches, double ridges,...

The Mediterranean Sea and in particular the Liguria region have always been suffering from severe geohydrological events. Landform features and autumnal atmospheric circulation deeply influence the hazard in Genoa city, the capital of Liguria, crossed by many streams: heavy rainfall can trigger flash floods involving structures and...

The Portofino promontory is characterised by springs supplying Camogli, Portofino and Santa Margherita Ligure towns. This research concerns a hydrogeological preliminary study of the Caselle springs, located in the San Fruttuoso valley at 325 m asl. Water circulation occurs in discontinuities of Portofino Conglomerate and has been investigated...

Terraces, traditionally sustained by dry stonewalls, occupy about thirty percent of the territory of Liguria. If constantly maintained, they effectively contribute to slow down the natural slope erosion. When no longer managed, terraces are recognized as one of the reasons for increased geomorphological risk along the slopes and, consequently,...

The city of Genoa (Liguria, Italy) and the Bisagno Valley are affected by frequent floods, oftenwith loss of human lives. Historically characterised by high flood hazards, the Bisagno Valleywas recently affected by a flood event on 9 October 2014, less than three years after the tragic flood event of 4 November 2011 when six people...
