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.
