Source and mouth of the Glenner
|
The Glenner (Rhaeto-Romanic: Glogn ) is by far the largest tributary of the Vorderrhein and runs in the Swiss canton of Graubünden . Glenner was also the name of a district of this canton that existed until 2001, the area of which was administratively divided into the Grisons Oberland region of Surselva from 2016 .
course
The wild river has its source near the border with the canton of Ticino . Here it is surrounded by mountains more than 3100 m high ( Piz Terri , 3149 m) and then flows through the Val Lumnezia . In the upper reaches, the river has cut a deep gorge that has black slate in a few places. At Suraua , the Glenner takes on its most important tributary, the Valser Rhine , which is significantly larger in size and length , and flows into the Vorderrhein after a good 10 kilometers at Ilanz . Here it has an average water flow of almost 9 m³ / s; During the snowmelt and after rainfall, the river usually has dark gray water.
bridges
10 road bridges, 7 pedestrian bridges and 1 railway bridge cross the Glenner.
