The Radurschlbach is an approximately 18 km long right tributary of the Inn in the Tyrolean Oberland .

course

The brook has its source in the Nauderer Mountains near the main Alpine ridge to the east below the Seekarköpfe at 2776  m above sea level. A. It flows initially in a northerly, then in a northwest direction through the Radurschltal , where it passes the Hohenzollernhaus . At the exit into the Inn valley, it cut into a narrow gorge, the Radurschlamm gorge. In the Inntal he pushed the Inn to the north side of the valley and raised an alluvial cone on which Pfunds -Dorf lies. To the north of it the stream flows into the Inn.

The most important feeders are the Nauderer Tscheybach with a catchment area of ​​14.5 km² from the left and the Pfundser Tscheybach with 18.0 km² from the right.

Catchment area and water supply

The catchment area of the Radurschlbach is 92.3 km², of which 0.55 km² (around 0.6%) is glaciated (as of 1998). The highest point in the catchment area is the bell tower at 3353  m above sea level. A. The water of the Radurschlbach, like that of the Nauderer Tscheybach, is completely drawn in at an altitude of around 1800 m and drained into the Gepatsch reservoir in the Kaunertal . This reduces the hydrologically effective catchment area by around 42 km².

At the Radurschl water intake, the creek has a level-glacial discharge regime with discharge peaks of up to 1.9 m³ / s in the summer months.

ecology

The stream in the uninhabited Radurschltal is largely natural, on flatter stretches of the river it has developed several arms or meanders in some cases . The ecological condition of the Radurschlbach is classified as very good, the bottom of the brook is unobstructed, the banks are only built up at certain points, with the exception of the local area of ​​Pfunds, where the brook is completely built up and has a poor ecological condition.

use

In addition to being discharged into the Gepatsch reservoir, the water from the Radurschlbach is used by the Hohenzollernhaus small power station. In addition, the stream feeds numerous whales , which are used for irrigation in the area with little rainfall.
