The Velino is a river in central Italy, a tributary of the Nera. Its source is located on Monte Pozzoni's slopes (1,903 m) near Cittareale. Aftwards, it runs through a narrow valley next the Mount Terminillo, known as "Gole del Vento" ("Wind's Ravines") and, near Antrodoco, receives the Peschiera Springs, which have a discharge of some 18 m/s (9.5 m/s is sent to Rome) through an aqueduct.
Then, it receives the waters of its left tributaries Salto and Turano [it], and then enters the plain of Rieti, where its discharge if further increased by other minor streams to reach 60 m/s. Near Papigno, it falls into the Nera forming the famous Cascate delle Marmore falls.
