Flood management of the Tevere River at Nazzano barrage, upstream Rome
This paper reports the results of a hydrodynamic study developed by an unsteady monodimensional numerical model, supporting the management of Tevere river floods in use by Enel at Nazzano barrage since the 1960s. The model compares the effects of Enel operational criteria with the results obtained by applying the principles indicated by National Technical Services […]

Campotosto Dams, an experience of the importance of back analysis for the evaluation of geotechnical properties
This paper contains the results of the back analysis performed after the earthquake of April 2009 (L’Aquila Central Italy) on the Rio Fucino gravity dam (reservoir of Campotosto, L’Aquila).The elaboration of the back analysis made it possible to estimate the shear strength at the contact surface between the dam and the rock foundation and the […]

Sustainable management of hydroelectric basins: multicriteria analysis on social and environmental assessment of alternative sites for settlement of dug sediments
​Referring to the management of artificial basins, the reservoir sedimentation caused by erosion process and the consequent sediment transport and deposit in the basin is a fundamental aspect to be considered. The filling, or partial filling, with silt of a reservoir that receives fine-grained sediment brought in by streams and surface runoff leads to a […]

Long-time behaviour of exposed geomembranes used for the upstream face rehabilitation of concrete and masonry dams
​The use of exposed geomembranes for the rehabilitation of concrete and masonry dams was introduced in Italy in 1976, when the entire upstream face of a 11 m high masonry dam was lined with a 2 mm thick PVC (polyvinyl chloride) geomembrane as waterproofing element (Lago Miller).In the following applications (among which Lago Nero, 1980; […]
