The Upper Adriatic Sea basin comprises a very precarious coastal
environment subject to continuous changes which prove appreciable
not only over the geological scale but also in historical and
modern times. According to some Authors the Venice Lagoon was
formed 2000-3000 years ago, and other lagoons (e. g. the Grado
Lagoon in the northernmost part of the Adriatic) are even more
recent. In addition to lagoons, the Upper Adriatic coastal area
includes salt and fresh-water marshes and reclaimed land separated
by several watercourses originating from the Alpine and Apennine
ranges with a ground elevation not exceeding in many places 2 m
above the mean sea l. evel (msl). A significant fraction of this
lowland is already now below msl because of natural and
anthropogenic land subsidence, land reclamation and sea level rise
occurred over the last century. Natural land subsidence is still
under way as a result of deep downward tec tonic movement and
consolidation of soils deposited in the most recent time. An
thropogenic subsidence is primarily due to groundwater pumping for
agricultural, industrial, civil, and tourist use, and to gas
withdrawal from a large number of gas fields scattered through the
Upper Adriatic basin, and may still continue, al though at a
reduced rate, in the years to come. At the same time msl is
expected to rise in the next century due to global climate change,
mainly because of the greenhouse effect.

The city of Venice, Italy, has been subjected to periodic
flooding, or acqua alta, for centuries. "Venice Shall Rise Again"
presents a unique proposition to halt this flooding. Based on years
of work and experiment, experts Gambolati and Teatini describe an
innovative yet technologically simple, economically inexpensive,
and environmentally friendly project to raise Venice by 25-30 cm
over ten years by injecting seawater into 650-1000 m deep
geological formations. This project would be conducted under
conditions of absolute safety, stability and integrity conserving
the unique artistic and architectural patrimony of this deeply
beloved city. Beginning with a brief history of the Venetian
Republic, "Venice Shall Rise Again" addresses the actions
undertaken by Venice to protect the city and the lagoon from the
sea and land attack for more than a millennium, including the MoSE
project, a system of mobile barriers presently under construction.
Detailed in its engineering details and ideas, but with enough
background information and context to help the interested reader
understand the concepts, this book will be of interest to all
readers concerned about the fate of Venice.
Provides a history of the technical measures taken by the Venetian
Republic to preserve the lagoon and the city or VeniceDetails
