THE GEOLOGICAL AND HYDROGEOLOGICAL STUDY: 'BACK TO THE PAST' AS AN INNOVATIVE APPROACH TO PRELIMINARY FEASIBILITY STUDIES FOR UNDERGROUND HYDRO-POWER PLANTS IN ALPINE ENVIRONMENT

摘要

A Prc-fcasibility study for the renewal of the Orco Valley hydropower plants (Turin Province, NW Italy), owned by AEM Torino S.p.A., is presented. This work stresses the advantages of a field study based upon modern structural analysis, in contrast to the common trend to rely almost exclusively on preliminary borehole campaigns.
