The Valser Bach , also Valserbach , is a right tributary of the Sill in the Valser Valley in the Zillertal Alps in Tyrol .
course
The Valser Bach arises from the confluence of the Alpeiner Bach and Zeischbach (also: Tscheischbach) in Innervals. The 5.3 km long Alpeiner Bach rises below the Alpeiner Ferners on the Tux main ridge at 2175 m above sea level. A. ( ⊙ ). The Zeischbach rises on the northern slope of the Kraxentrager at an altitude of 2424 m above sea level. A. ( ⊙ ) and has a length of 4.0 km. The Valser Bach then flows in a north-westerly direction through the Valser Valley. In St. Jodok am Brenner it unites with the Schmirnbach coming from the Schmirntal , before flowing into the Sill 1 km further on at Stafflach (municipality of Steinach am Brenner ). Occasionally the lowest section from the confluence is also referred to as Schmirnbach. The Valser Bach is 8.3 km long, with the Alpeiner Bach as the longest source brook it comes to a length of 13.6 km and a difference in altitude of 1079 m.
Numerous field names in the Valser Tal, such as Sillalm, Sillkogel or Sillbach, indicate that the Valser Bach used to be seen as the upper reaches of the Sill.
Catchment area and water supply
The catchment area of the Valser Bach is 110.3 km², of which 1.8 km² (around 1.5%) are glaciated. The highest point in the catchment area is the Olperer at 3476 m above sea level. A. At its confluence, the Schmirnbach drains with 62.0 km² a significantly larger catchment area than the Valser Bach with 47.3 km².
The mean discharge at the St. Jodok gauge, below the confluence of the Valser Bach and Schmirnbach rivers, is 3.37 m³ / s, which corresponds to a discharge rate of 31 l / s · km². The Valser Bach has a runoff regime that is typical for a mountain stream without any significant glacial influence. The mean discharge in the month of June with the most water (7.59 m³ / s) is seven times higher than in the month of February with the least water (1.07 m³ / s).
ecology
The upper course and the source brooks are in the nature reserve Valsertal, they are natural, partly meandering and overgrown with gray alder - alluvial forests. The rest is built with shorter, more natural sections. The entire course of the Valser Bach has water quality classes I-II (as of 2005).
