Short summary

Genoa serves as a case study for geohydrological risks. Cloudbursts of a few hours seem to have a rainfall intensity greater than in the past; this causes an increase in hydrometric levels of the watercourses that quickly reach alarming values, close to overflowing. This factor, added to growing urbanization, has inevitably produced a general trend of increasing risk. Urbanization is particularly notable regarding the narrowing process in all cross sections of Genoa's watercourses.
