The Tuxbach flows through the Tuxertal in Tyrol ( Austria ) and flows into the Zemmbach between Finkenberg and Mayrhofen , shortly before it reaches the Ziller .
course
The Tuxbach arises from the confluence of three source streams near Waldeben below the Tuxer Joch . The Große Kunerbach , the Kleine Kunerbach and the Schwarzbrunnerbach are fed by the Tuxer Ferner and Schwarzbrunnerkees. Shortly before reaching the wide valley floor near Hintertux , the stream flows through the Schraubenfallhöhle, a 105 m long through cave that it formed around 10,000 years ago after the end of the Würm glacial period .
The Tuxbach then initially flows in a north-easterly direction through the Tuxertal, which turns south-east near Vorderlanersbach. It flows into the Zemmbach between Finkenberg and Mayrhofen . The most important feeders are the Junsbach and the Nigglasbach, which flow from the left at Juns and Vorderlanersbach. Other tributaries from both sides reach it partly via waterfalls worth seeing, such as B. the Schleierfall of the Weitentalbach from the left or the screw waterfall of the Schwarzbrunnerbach from the orographically right side. At Persal the brook is crossed by the listed Devil's Bridge.
The Tuxbach forms the border between the Tux Alps in the north and the Zillertal Alps in the south.
Catchment area and water supply
The natural catchment area of the Tuxbach is around 130 km², of which 5.2 km² (4%) are glaciated (as of 1988). The highest point in the catchment area is the Olperer at 3476 m above sea level. A. The hydrologically effective catchment area has been reduced by 13.3 km² due to the diversion of the Schwarzbrunnerbach into the Schlegeis reservoir .
The mean discharge at the Persal gauge, 2 km above the estuary, is 3.77 m³ / s, which corresponds to a discharge rate of 32.5 l / s · km². The Tuxbach has a similar flow regime , which is characterized by the snowmelt in spring. The mean discharge in the month of June with the most water, at 8.48 m³ / s, is 7.5 times higher than in the month with the least water, February with 1.13 m³ / s.
ecology
The Tuxbach is built over long stretches, below the confluence of the Tuxeggbach it is classified as natural. The Tuxbach has water quality classes I-II.
