The Casaluna is a small river in the department of Haute-Corse, Corsica, France. It is a tributary of the Golo.
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). 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). In its lower course it defines the eastern boundary of the Forêt de Pineto. [2]
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. [3] The bridge carried the D39 road over the lower Casaluna about 3 kilometres (1.9 mi) above its mouth. [4] 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. [3] On 23 July 2020 a public inquiry was launched prior to environmental authorization of the project. [5]
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. [6]
