Abstract
A fully-coupled finite element model is used to calculate the surface subsidence of two regions in Northern Italy. In one case the subsidence of Venice is analyzed, and the second involves the surface settlement of the Polesine region. The subsidence of Venice is caused by the extensive withdrawals of ground water in the neighbouring industrial area of Marghera and that of the Polesine region by the withdrawal of water and gas. The finite element model clearly indicates the short time delay between changes in the withdrawal rate in Marghera and the resulting hydraulic head decline and subsidence in Venice. The finite element model is also checked against calculations made by other research workers who utilized an uncoupled model. The Polesine has also been well documented with respect to the surface subsidence caused by water and gas removal from the underlying reservoir sediments. These values formed the basis for a comparison study with the finite element consolidation model. Finally, a hypothetical reservoir model of Ravenna, another historical town in Italy, is analyzed.
