The Intervention of Hydrogeophysics in the Economics of Groundwater Exploitation and Management in Sicily
1989
Abstract The problem of the preservation of water resources in Sicily presents various aspects, some of which have been treated by a number of works. Among the different applied methodologies, the geophysical ones occupy an important place. Their contribution, directed to an economic and efficient exploitation and management of groundwaters, can be useful for selected “risk” areas as well as for more regional programmes. In fact, uncontrolled drillings on relatively rich aquifers occur in several zones of this island; the economically disadvantageous exploitation causes also heavy impoverishment and pollution phenomena. The fragmentation of charges and the lack of a planning Regional Body m…
Comparative tests on different multi-electrode arrays using models in near-surface geophysics
2008
In this paper, the response of different synthetic models to geoelectrical multi-electrode surveys is studied. The models considered are related to two main problems, which are very common in geophysical research regarding hydrogeology and engineering. The first class of models represents buried walls, similar archaeological remains or remains of buried foundations; the other class corresponds to a sea-water intrusion of a fresh water aquifer, which is generally studied in hydrogeophysics. A set of 2D simulations, starting from the synthetic models, was carried out to compare the behaviour of the different arrays when acquiring measurements of electrical resistivity tomography. For each mod…
