The Aniene River rises in the Simbruini Mountains, runs for about 100 km and empties into the Tiber River within Rome's urban area. In its last stretch, it flows from Tivoli to the Tiber river through the travertine deposits of the Tivoli and Bagni Albule area and the volcanic and alluvial sediments of the roman countryside. The quality of the water found in the rivers drainage basin, suffers enormously from human activities, especially in the lower course. Our main goal was to demonstrate that remote sensing may be used to detect and compare natural conditions and situations resulting from human activities as regards the hydrogeological hazard of the Aniene River, thus directing future interventions aimed at mitigating human impact and restoring previous environmental balance. This work describes a procedure that, starting from cartography data acquisition and satellite image processing, permitted us to produce an hydrogeological vulnerability map of the lower course of the Aniene River using an option of the Xpace module multilayer modelling (software Easy Pace by PCI). In the future we propose to extend this procedure to the entire Aniene basin and to relate the hydrogeological vulnerability map with human activities that impact on the area.
