It was the great hydraulic intervention (271 b.Ch.) of the Roman consul Curio Dentato who brought to life the Falls, had not only the merit to receive the Velino waters that became swampy in the Sabina (the Reatina Plain), but also connected the two catchment basins (Nera-Velino) and the two rivers became one with one attributing to the other. If on one hand the so-called “Curiano Channel” made life easy for the Sabina inhabitants, on the other hand it created many inconveniences to the lower Valnerina and for the Interamna Plain ( Terni ) inhabitants. It was, during the overflowing periods of the two rivers that the territory underneath was often subjected to flooding.
