Base map: total sea level change (in mm/yr) between 1992 and 2014. Insets: vertical land motion (land subsidence is negative) detected by SAR interferometry in representative low-lying coastal regions After: Melet, Teatini, et al., 2020 (pdf) Rupture depth d_r,acr versus hydrogeological setting (H_r) and pressure change (Δp). (a) 3-D regression surface obtained by a multi-variate analysis of the outcomes of the numerical modelling and (b) behavior of the 3-D surface for a few Δp values.

TerraSAR-X has been extensively
used to study land subsidence in
the Venice Lagoon, Italy, with
the aim of quantifying the natural

Mekong River delta: eolution of the finite element mesh. The number of triangular elements in each temporal interval is provided. Note that the mesh size increases in time to account for deposition. The age of the grid elements is highlighted by colors.

Efficient global optimization of reservoir geomechanical parameters based
on synthetic aperture radar-derived ground displacements: comparison between
the west-east land displacements measured by SqueeSAR (colored map) over the
Tengiz reservoir (Kazakhstan) and those computed by the FE model (black isolines)
calibrated via EGO. Positive values mean eastward movement. The trace of the
reservoir is shown by the orange line.

Numerical simulations of Holocene salt-marsh dynamics under the hypothesis of large soil deformations: simulated salt-marsh evolution and distribution of column strain in the case of heterogeneous soil accretion. In particular, each new element added to the FE mesh takes the properties of organic material or inorganic material randomly.

VENICE SHALL RISE AGAIN
Engineered Uplift of Venice through Seawater Injection
This book is authored by Profs. Gambolati and Teatini who, for decades, have carefully studied the geology and the groundwater phenomena in the region surrounding the city of Venice in Northeastern Italy. They discuss a recently proposed, daring, and innovative engineering approach that could create a substantial elevation of the ground surface of the region and, consequently, a mitigation of the periodic flooding of the city.

Using an accurate 3-D reconstruction of the Quaternary deposits, developed very recently from about 1050 km of multichannel seismic profiles and eight exploration wells, Teatini et al., 2011 (pdf) provide a reliable predictions of the expected uplift of Venice because of seawater injection into deep aquifers through 12 wells located on a 10 km diameter circle (marked in red in the figure). Despite the complex geometry of the injected formations, as is shown by the axonometric view of the three-dimensional FE model sectioned along the coastline of the northern Adriatic Sea (vertical exaggeration is 10x), a proper adjustment of the injection pressure in each well, according to its position with respect to the main features (extent and thickness) of the injected geologic sequences, allows for a prediction of a quite uniform 26 cm uplift 10 years after pumping inception. Land subsidence in drained cultivated peatlands is responsible for a number of serious environmental concerns and economical problems at both the local and the global scale. In low-lying coastal areas it enhances the risk of flooding, the saltwater contamination of shallow aquifers, and the maintenance costs of the systems that help keep the farmland drained. Since the subsidence is a major consequence of the bio-oxidation of the soil organic fraction in the upper aerated zone, cropped peatlands in temperate and tropic regions are important sources of CO₂ into the atmosphere. A 4-year long experimental study has been performed in a drained peatland located south of the Venice Lagoon, Italy, to help calibrate a land subsidence model developed to predict the expected behavior of the ground surface elevation.
