Excerpts;
The water flowing through Venice’s famous canals laps at buildings a little higher every year, and not only because of a rising sea level.
Although previous studies had found that Venice has stabilized, new measurements indicate that the historic city continues to slowly sink, and even to tilt slightly to the east…
The new study, used a combination of measurement techniques that provided data on both the absolute and relative shifts in elevation of the area, along with GPS measurements and space-borne radar (InSAR) data…
The findings will be published March 28 in Geochemistry, Geophysics, Geosystems, a journal of the American Geophysical Union.

Venice Menace: Famed City is Sinking & Tilting, Our amazing Planet
Venice subsided about 120 mm in the 20th century due to natural processes and groundwater extraction, in addition to a sea level rise of about 110 mm at the same time, Teatini said in a statement. Bock and his colleagues calculate that the city and surrounding land could sink by about 80 mm (3.2 inches) relative to the sea in the next 20 years if the current rate holds steady.

Known to Venetians as the acqua alta, or “high water,” flooding driven by high tides submerges the lowest 14 percent of the Italian destination four times a year, on average. And it’s only getting worse.
