Cartografia Idrogeologica sperimentale nel settore sud-orientale dei Monti Cimini (Lazio)

This study was realized within a collaboration agreement between the “Dipartimento per i Servizi Tecnici Nazionali-Servizio Geologico Nazionale della Presidenza del Consiglio dei Ministri” (now “ISPRA, Servizio Geologico d’Italia/Dipartimento Difesa del Suolo”) and “Università degli Studi “Roma Tre”, Dipartimento di Scienze Geologiche”, aimed to the testing of the Italian guidelines for the hydrogeological survey and mapping at the 1:50,000 scale in the south-eastern sector of the volcanic district of the Monti Cimini, in central Italy. The study has concerned the collection of geologic and hydrogeologic information from the scientific literature, the realization of a hydrogeologic field survey (four seasonal field investigations in a year during 2002-2003) consisting in well and spring monitoring and in stream gauging measurement finalized to the definition of the groundwater-surface water relationships. The collected data were also used for a stratigraphic and structural geology study aimed to the elaboration of hydrogeologic sections that, along with the discussion of the elements characterizing the hydrologic balance of the Treia River Basin, representing the main stream in the study area, have allowed the reconstruction of the local groundwater flow field. The geologic and hydrogeologic information has been organized in different informative layers interfaced with a specific suitable database. The hydrogeologic map on purpose realized at the scale 1:50,000 reports the main hydrogeologic features of the study area and the results of the testing of the cartographic guidelines
