Geography

The Nera river has a length of 116 km (72 mi), and a drainage basin with an area of approximately 4,280 km² (1,653 sq mi).

Course

The Nera river starts in the Monti Sibillini, within the Monti Sibillini National Park (Italian: Parco Nazionale dei Monti Sibillini), at an elevation of about 902 m (2,959 ft)., in the comune of Castelsantangelo sul Nera, Province of Macerata, Marche.

The river flows through the comuni of Castelsantangelo sul Nera, Viso and Ussita in the Marche and then, after about 20 km (12 mi), it flows in the Umbria. After flowing through the province of Perugia, it gets in the province of Terni and keeps flowing to the east and flows through the city of Terni.

After flowing through the city of Narni, it gets into the Lazio region (Province of Viterbo) and soon finally flows in the Tiber river as a left tributary near the city of Orte.
