Source and mouth of the Hinterrhein

The Hinterrhein , in the Rhaeto-Romanic idiom Sutsilvan Rein Posteriur , is one of the source rivers of the Rhine and is located in the Swiss canton of Graubünden . It rises on the slopes of the Rheinwaldhorn , Güferhorn and Rheinquellhorn and unites near Reichenau with the Vorderrhein to form the river now known as the Rhine.

geography

Course and valley landscape

The valley of the Hinterrhein consists of three terrain chambers from top to bottom: the Rheinwald with Splügen as the largest village, the Schams with Andeer and the Domleschg / Heinzenberg region with Thusis . In between are the once feared traffic obstacles of the Roffla Gorge above the Schams and the Viamala below.

The origin of the Hinterrhein can be reached in around four hours on foot from the village of Hinterrhein via the Zapporthütte SAC ( 2276  m ). The uppermost part of the valley is connected to Ticino via the San Bernardino Pass ; The historic Splügen Pass leads from Splügen to Chiavenna in the Italian province of Sondrio . From Thusis the road branches off to Davos , respectively to the Julier Pass and the Albula Pass .

The Hinterrhein is at 64 kilometers and a maximum, measured over the Dischmabach as the longest flow path, 72 kilometers in length slightly shorter than the Vorderrhein with, measured over the Rein da Medel , about 76 kilometers. However, with a water flow of 59.6 m³ / s, it is larger than the Vorderrhein, which carries 53.8 m³ / s. On the question of the source of the Rhine, see Rheinquelle .

The Albula is the most important tributary of the Hinterrhein. With natural runoff, which is currently not present in both rivers due to the use of hydropower, the Albula at the confluence in Fürstenau is even larger with an average of 29.1 m³ / s than the Hinterrhein, which has 27.3 m³ / s of water there.
