Forty year evolution of FE models used to simulate the geomechanics of the aquifer systems underlying the Venice Lagoon, Italy. (a) Vertical cross section of the 3-D axi-symmetric mesh of Gambolati et al. [1974] made from 812 nodes and 1000 annular elements (each rectangle was divided into two triangles). The model run on a IBM PS44 (256 Kb RAM). (b) Perspective view of the quasi 3-D mesh of the Venetian multiaquifer system of Teatini et al. [1995]. Each aquifer was discretized into 1158 triangles with 608 nodes and each aquitard column into six linear elements, for an overall number of 18,848 nodes. The model run on an IBM RISC6000/560 (512 MB RAM). (c) Axonometric view of the tetrahedral mesh used to predict the anthropogenic uplift of Venice by seawater injection into saline aquifers [Teatini et al., 2011a]. The mesh totaled 1,905,058 elements and 328,215 nodes with simulations performed on a Core-I7, 2.66 GHz processor-based workstation (6 GB RAM).

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.
