Salso

The River Salso (Sicilian: Salsu), also known as the Imera Meridionale (Greek: Ἱμέρας; Latin Himera), is a river of Sicily. It rises in the Madonie Mountains (Latin: Nebrodes Mons; Sicilian: Munti Madunìi) and, traversing the provinces of Enna and Caltanissetta, flows into the Mediterranean at the western end of the Gulf of Gela at the seaport of Licata, in the Province of Agrigento. Its small deltaic system there is dominated by marine processes rather than fluvial ones. It is a seasonal torrent, with brief but violent floods during the winter rains (from November to February), and all but dry in summer droughts. In November 1915 the iron bridge across the river's mouth collapsed during floods, and 119 people were swept away in the flood and lost. The Salso, which is the longest river of Sicily at 144 kilometres (89 mi), has a drainage basin area of about 2,122 square kilometres (819 sq mi).

The river's historically changeable meanders across the low coastal plain have been artificially channeled into the Canale di Sicilia, and the marshes drained for agriculture. Until the late nineteenth century it had two distributory channels, the second debouching 5 kilometres (3 mi) to the west. The mouth of the Salso has been advancing during historical times, and wind and wave formerly distributed its sand and silt to the beaches of the Gulf of Gela.

Himera was the ancient name of two rivers in Sicily, the Grande flowing to the north into the Tyrrhenian Sea, and the Salso to the south coast of the island, but which, by a strange confusion, were regarded by many ancient writers as one and the same river, which is in consequence described as rising in the center of the island, and flowing in two different directions, so as completely to divide Sicily into two parts. According to Vibius Sequester, this idea dates back to the time of Stesichorus, who was himself a native of the city of Himera. Pomponius Mela is, however, the only ancient geographer who adopts it.
