• Differential SAR interferometry has demonstrated a good potential to derive land subsidence information for urban areas at sub-cm vertical accuracy and relatively low cost. In addition, SAR interferometry exhibits complementary characteristics to the levelling surveys, because it has the capability to map large urban areas (i.e. where stable structures permit the formation of a coherent phase signal over time) at high spatial resolution, whereas the high precision levelling surveys can be used outside of the cities and to set up a reference point for the SAR subsidence values. In the case of the Venice historical center, where high precision levelling data are available in less than 150 benchmarks, 2-3 hundred meters spacing, SAR interferometry has the capability to monitor the vertical displacements with a resolution of 30 m.

(2002)Evidences of the present relative land stability of Venice, Italy, from land, sea, and space observations. Geophys. Res. Lett., 29 (12), doi:10.1029/2001GL013211, 2002. AGU. In this research the elevation loss of Venice relative to the mean sea level was determined with an integrated analysis of leveling, SRI and tide-gauge measurements. Nowadays, the Venetian soil is quasi-stable and the northern Adriatic sea level is not significantly rising. In spite of these reassuring results, over the last century land subsidence and eustacy concurred to make the relative sea level in Venice 23 cm higher. This has brought about a seven-fold increase of flooding events with great inconvenience for the population and enormous damage to the cultural heritage. Note that the man-induced land subsidence, which occurred during the 1950s and 1960s, is equivalent to about a two centuries of natural subsidence on the present day scale. Even if significant interventions have been made in the last decade, at the beginning of the new millennium the historic and architectural treasures of Venice are still deeply compromised by the ‘‘acqua alta’’ phenomenon. Moreover, the hypothesis of a future dangerous rise in the sea level due to climate change (literal)

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 (literal)
