The “Cavo Napoleonico” (Reno River Basin, Italy) represents one of the most important hydraulic structures in the low Po plain. The "Cavo Napoleonico" was designed by the technical commission set up by Bonaparte in 1808, as a means to divert the Reno River flood waves into the Po. Unfortunately, today after 200 years, the diversion canal is not yet fully operational. This is mainly due to heavy seepage problems related to the presence of high permeability materials at the bottom, which were already detected during the original tests. This paper describes the long history of the canal, the additional hydraulic works implemented from the first unsuccessful hydraulic tests, the hydrogeologic monitoring and the geognostic tests (drillings and geophysical investigations with GPR surveys) subsequently carried out. The hydrogeological and geotechnical models, set up using the available observations supplemented by laboratory data, are here described. Embankments seepage/stability analyses have been finally performed in order to estimate reliability water level up to the original maximum design.

Abstract
The “Cavo Napoleonico” (Reno River Basin, Italy) represents one of the most important hydraulic structures in the low Po plain. The "Cavo Napoleonico" was designed by the technical commission set up by Bonaparte in 1808, as a means to divert the Reno River flood waves into the Po. Unfortunately, today after 200 years, the diversion canal is not yet fully operational. This is mainly due to heavy seepage problems related to the presence of high permeability materials at the bottom, which were already detected during the original tests. This paper describes the long history of the canal, the additional hydraulic works implemented from the first unsuccessful hydraulic tests, the hydrogeologic monitoring and the geognostic tests (drillings and geophysical investigations with GPR surveys) subsequently carried out. The hydrogeological and geotechnical models, set up using the available observations supplemented by laboratory data, are here described. Embankments seepage/stability analyses have been finally performed in order to estimate reliability water level up to the original maximum design.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
