“…The influence of land subsidence on these communities and environments can be very significant, increasing vulnerability to saltwater intrusion and flooding, threatening agriculture and ecological systems. Presently, land subsidence caused mainly by extraction of groundwater is threatening Jakarta (Ng et al, 2012), Ho Chi Minh City (Erban et al, 2014), Bangkok (Phien-wej et al, 2006), Shanghai (Dong et al, 2014), i.e. rapidly expanding urban areas which require huge amounts of water for domestic and industrial water supply.…”

Regional and local land subsidence at the Venice coastland by TerraSAR-X PSI

et al. 2015

Abstract.Land subsidence occurred at the Venice coastland over the 2008-2011 period has been investigated by Persistent Scatterer Interferometry (PSI) using a stack of 90 TerraSAR-X stripmap images with a 3 m resolution and a 11-day revisiting time. The regular X-band SAR acquisitions over more than three years coupled with the very-high image resolution has significantly improved the monitoring of ground displacements at regional and local scales, e.g., the entire lagoon, especially the historical palaces, the MoSE large structures under construction at the lagoon inlets to disconnect the lagoon from the Adriatic Sea during high tides, and single small structures scattered within the lagoon environments. Our results show that subsidence is characterized by a certain variability at the regional scale with superimposed important local displacements. The movements range from a gentle uplift to subsidence rates of up to 35 mm yr −1 . For instance, settlements of 30-35 mm yr −1 have been detected at the three lagoon inlets in correspondence of the MoSE works, and local sinking bowls up to 10 mm yr −1 connected with the construction of new large buildings or restoration works have been measured in the Venice and Chioggia historical centers. Focusing on the city of Venice, the mean subsidence of 1.1 ± 1.0 mm yr −1 confirms the general stability of the historical center.

“…This phenomenon has been documented, especially in the last half of the XX century, in different parts of the world, such as in Japan (see e.g. Daito and Galloway, 2015), Mexico (Toscana and Campos, 2010), Thailand (Phien-wej et al, 2006) and Bangladesh (Brown and Nicholls, 2015;Howladar and Hasan, 2014). Literature on the effects of land-subsidence in coastal areas is rich, see e.g.…”

Effects of anthropogenic land-subsidence on inundation dynamics: the case study of Ravenna, Italy

Abstract. Can differential land-subsidence significantly alter river flooding dynamics, and thus flood risk in flood prone areas? Many studies show how the lowering of the coastal areas is closely related to an increase in the flood-hazard due to more important tidal flooding and see level rise. The literature on the relationship between differential land-subsidence and possible alterations to riverine flood-hazard of inland areas is still sparse, although several geographical areas characterized by significant land-subsidence rates during the last 50 years experienced intensification in both inundation magnitude and frequency. We investigate the possible impact of a significant differential ground lowering on flood hazard over a 77 km 2 area around the city of Ravenna, in Italy. The rate of land-subsidence in the study area, naturally in the order of a few mm year −1 , dramatically increased up to 110 mm year −1 after World War II, primarily due to groundwater pumping and gas production platforms. The result was a cumulative drop that locally exceeds 1.5 m. Using a recent digital elevation model (res. 5 m) and literature data on land-subsidence, we constructed a ground elevation model over the study area in 1897 and we characterized either the current and the historical DEM with or without road embankments and land-reclamation channels in their current configuration. We then considered these four different topographic models and a twodimensional hydrodynamic model to simulate and compare the inundation dynamics associated with a levee failure scenario along embankment system of the river Montone, which flows eastward in the southern portion of the study area. For each topographic model, we quantified the flood hazard in terms of maximum water depth (h) and we compared the actual effects on flood-hazard dynamics of differential land-subsidence relative to those associated with other man-made topographic alterations, which resulted to be much more significant.
