ABSTRACT
The city of Venice is very vulnerable to loss in surface
elevation as a result of subsidence and eustacy because of
its small elevation above sea level. The alarm of the
scientific community related to this persistent problem is
increasing because of the forecasts of sea level rise
caused by global warming. In order to evaluate the present
relative subsidence of Venice, a study has been performed
by combining high precision leveling,
Satellite Radar Interferometry (SRI) and tide gauge
measurements. The analysis of the most recent data points
out with an unprecedented detail the present ground stability
of the city.
