Glâne (river)
Top- Glane, German partially written Glane, Fribourg Patois La Yanna / i, is a 37 km long left tributary of the River Sarine (French: Sarine ), in the canton of Fribourg in Switzerland. The area of the river basin is approximately 193 km ². The river name is derived from the Celtic word glana ( pure).
The headwaters of the Glane is located in the south-western Fribourg Molassehügelland the country, east of the headwaters of the Broye, in the municipality of Le Flon north of the village Bouloz. It rises in a depression in at around 850 meters above sea level. M. between the forest heights of La Rape in the West and in the East La Tossaire and initially named Rio d' Enfer.
In the first two kilometers of the stream flows to the northwest, before it changes its flow direction to northeast and used by the glacial Rhône glacier prescribed, always running from southwest to northeast terrain structures in Molassehochplateau. From the Siviriez Glane runs over a distance of 13 km, in a wide open mountain valley, the valley floor at 700 m above sea level on average. M.. Lies. The waters mastered in this section a height difference of only just 50 meters. The up to two kilometers wide mountain valley once formed at different places extensive peat lowlands, which were ameliorated the late 19th century or early 20th century. The river here is therefore channeled and straightened on long distances. The upper valley of the Glane parallel to the approximately six kilometers to lying to the northwest middle reaches of the Broye, whose valley is but 200 feet below.
Below Villarimboud proposes a Glane an eastern direction of flow, while having a predominantly natural or near-natural running with meanders and marshy flood plain here. In the valley at Autigny flow from the south, the two main tributaries, namely the Neirigue and Glèbe.
In Autigny the Glane changes its direction of flow again to the northeast. She digs it deeper and deeper into the molasse of the environment and forms a gorge-like, partially crossed by sandstone cliffs wooded valley. After it has passed through the valley of Matran, opens the Glane below Villars -sur -Glane on 560 m above sea level. M., a few kilometers south of Freiburg, in the Sarine.
The water power of the Glane was formerly used in various places for the operation of mills and sawmills. While the lower reaches between Autigny and Matran is difficult to access, the high valley of the Glane was formed in the Middle Ages an important traffic route from Freiburg to Lausanne. Since 1862 the predominantly rural mountain valley is used because of its simple topography also of the railway line from Freiburg to Lausanne. Center of the upper Glane is the town of Romont, located on an isolated hill in the middle of the valley.
