Course


The Casaluna is 25.17 kilometres (15.64 mi) long. It crosses the communes of Aiti, Cambia, Carticasi, Castineta, Érone, Gavignano, Lano, Morosaglia, Saliceto and San-Lorenzo.[1]

The Casaluna rises to the west of the 1,712 metres (5,617 ft) Monte Muffraje in the commune of Carticasi.[2] Its source is at an altitude of 1,559 metres (5,115 ft).[3] It flows with many meanders in a generally northwest direction to its confluence with the Golo to the south of Ponte Leccia.[2] Its mouth is at an altitude of 207 metres (679 ft).[3] In its lower course it defines the eastern boundary of the Forêt de Pineto.[2]


Bridge


On 24 November 2016 an exceptionally violent storm hit central Corsica and caused widespread flooding. An ice jam on the Casaluna river washed away a centuries-old bridge that spanned it.[4] The bridge carried the D39 road over the lower Casaluna about 3 kilometres (1.9 mi) above its mouth.[5] A temporary bridge was thrown over the river in mid-January 2017, but could not carry the heaviest vehicles. In May 2020 work on a permanent replacement was scheduled to begin. Although some of the local people wanted the old bridge to be rebuilt, that would be vulnerable to a similar storm, which was expected to become increasingly common as the climate changed. Instead a modern bridge was to be built in place of the old one.[4] On 23 July 2020 a public inquiry was launched prior to environmental authorization of the project.[6]


Hydrology


The river's flow has been measured at Gavignano since 2013. The maximum instantaneous flow was 177 cubic metres per second (6,300 cu ft/s) on 16 March 2015. The maximum daily flow was 81.9 cubic metres per second (2,890 cu ft/s) on 2 October 2015.[7]
