Eustacy and land subsidence in the Venice Lagoon at the beginning of the new millennium

The secret gardener: vegetation and the emergence of biogeomorphic patterns in tidal environments

“…consistent with the local rate of RSLR for the twentieth century in the Venice Lagoon [41]). We consider three vegetation species with the same degree of specialization (λ = 5), which differ for different optimal elevation values (z 1 = 0.45 m,z 2 = 0.25 m andz 3 = 0.10 m above MSL) for the 'red', 'green' and 'blue' species (dashed black line in figure 3c,f,i).…”

Links between hydrology and sedimentology in the Lagoon of Venice, Italy

“…This last factor caused subsidence, calculated between 3.8 mm yr -1 (Carbognin and Taroni, 1996) and 6 mm yr -1 for the period 1930-1970(Sestini, 1992Bondesan et al, 1995). Following the end of groundwater pumping in the early 1970s, land subsidence has slowed down (Carbognin and Taroni, 1996;Tosi et al, 2002;Brambati et al, 2003;Carbognin et al, 2004;Teatini et al, 2005).…”

Flood Protection in Venice under Conditions of Sea-Level Rise: An Analysis of Institutional and Technical Measures

“…Scientists agree on the existence of fluctuation and the absence of an unambiguous trend (Canestrelli et al 2001;Pirazzoli and Tomasin 2002;Camuffo and Sturaro 2004;Carbognin et al 2004;Zanchettin, Traverso, and Tomasino 2006;Ferla et al 2007). According to Pirazzoli and Tomasin (2002) and Zanchettin, Traverso, and Tomasino (2006), fluctuation is correlated with internal Mediterranean dynamics and possibly solar activity, but the mechanisms are not fully clear, let alone well predicted.…”

“…According to several studies conducted in the past decades (Gatto and Carbognin 1981;Carbognin et al 1995Carbognin et al , 2004Carbognin et al , 2010Tosi et al 2002;Brambati et al 2003), the historical center of Venice has sunk about 23-25 cm relative to the mean sea level over the past one hundred years. Twelve cm was lost due to land subsidence, both natural (3 cm) and human-induced (9 cm due to groundwater extraction); 11-13 cm was lost as a consequence of global eustatic processes.…”

“…Detailed investigation conducted with SAR-based techniques shows that present subsidence is less than 1-2 mm/yr . Specifically, the historical center of Venice presents sinking rates that are generally lower than 1 mm/yr with an average of 0.5 mm/yr (Tosi et al 2002;Carbognin et al 2004Carbognin et al , 2010Teatini et al 2010). In the north and south lagoon and in the littorals however, Downloaded by [Vrije Universiteit Amsterdam] at 04:24 02 May 2013 the rate of subsidence is about 2-4 mm/yr mostly due to the subsoil characteristics, peat oxidation, and minor groundwater exploitation in these areas ).…”
