This work applies a one-dimensional model, based on K. Terzaghi's theory of vertical consolidation, to the calculation of land subsidence in the Venetian Lagoon, caused by extraction of water from artificial wells. Certain assumptions are made in order to compensate for the scarcity of data currently available, and these are discussed with regard to both the geophysical characteristics of the subsoil and the decline in piezometric level in the various strata. The interpretation of the results shows a direct correlation between water extraction and surface subsidence.
