The Mitterweißbach is a left tributary of the Traun in the Salzkammergut in Upper Austria .

Run and landscape

The Mitterweißbach arises from the confluence of Höllbach and Dürrer Pölitz in the Weißenbachtal east of a valley watershed , beyond which the Outer Weißenbach drains west to the Attersee .

The approximately 5.5 km long Höllbach rises in the Höll in the Höllengebirge below the Großer Höllkogel at an altitude of 1585  m above sea level. A. ( ⊙ ) with a spring discharge  of around 1500 l / s and then flows in a south-westerly to south-westerly direction to the Weißenbachtal.

The approximately 4.5 km long Pölitz drought rises at 1195  m above sea level. A. below the Gspranggupfs ( ⊙ ) and flows north until it reaches the valley floor of the Weißenbachtal at around 550  m . There it turns to the east and joins after about 1.2 km with the Höllbach coming from the left to the Mitterweißbach. This first flows through a gorge and then turns south to the Trauntal, where it flows into the Traun at Mitterweißbach .

With the Höllbach as the longest source stream, the Mitterweißbach comes to a length of 9.9 km and a difference in altitude of 1136 m.

Hydrology

The catchment area of the Mitterweißbach is 39.1 km², the highest point in it is the Große Höllkogel at 1862  m above sea level. A.

The mean discharge at the Mitterweißbach gauge, 1.20 km above the mouth, is 2.09 m³ / s, which corresponds to a relatively high discharge rate of 59.5 l / (s km²). The runoff regime is a nival transitional regime, the monthly mean of the month with the highest runoff, April, at 3.09 m³ / s, is almost two and a half times higher than that of the month with the lowest runoff, February, at 1.29 m³ / s.

ecology

The Mitterweißbach mostly flows in a relatively natural bed with a width of around 10 m and flat banks, which  are severely impaired in several places by the expansion of the parallel Weißenbacher Straße . The stream carries rubble and debris as well as dead wood and forms gravel and sandbanks when the water is low . Over long stretches it has a wood that accompanies the bank, which consists mainly of white willow , sycamore maple , common spruce , common ash , common hazel and black alder .

The water quality class is I-II throughout the course.

History and name

The name Weißenbach was first mentioned in documents in the year 829 in connection with the Salzburg property as ad Uuizinpah and refers to the clear water. The name of the source brook Pölitz, which is derived from the Slavic * Bělica to bělь 'white', has the same meaning .
