Abstract

A mathematical model for the study of piezometric variations induced by an impervious wall E. Crest az, L. Patata, P. Pambianco Department of Hydraulic Resources, Aquater S.p.A. (ENI ABSTRACT A mathematical model was implemented to study the behaviour of an aquifer located near an abandoned chemical industrial plant in southern Italy. A geo-hydrogeological and geochemical study pointed out that the level of pollution remains high, although the plant has been closed for 10 years. The main polluting sources were found within the plant's premises. A project to build an impermeable diaphragm around these sources, reaching the aquifer bottom, was proposed. This diaphragm would block a significant portion of the aquifer causing piezometric variations. An assessment of the aquifer is highly recommended prior to construction of said diaphragm. A flux model was implemented using the SEFTRAN code [5], a finite element 2-D code which is based on the numerical solution of the two
