Catchment area 1.6 km²

The Rosenbach is a brook in the Viennese districts Ottakring and Penzing . It is a left tributary of the left Vienna river collecting canal and is partly managed as a brook canal .

course

The Rosenbach has a total length of 3074 m. Of this, its initially above-ground course accounts for 2540 m with a height difference of 166 m. Its catchment area is 1.6 km².

The stream has its origin in the Jubiläumswarte pond on the Gallitzinberg , in the district part of Ottakring of the 16th district of the same name Ottakring. It is fed by several small feeders, including the outflow from the Heschteich. It continues through the Rosental in the district of Hütteldorf of the 14th district of Penzing. He passes several allotment gardens . It flows through the Dehnepark , where it feeds the Dehnepark pond.

From the intersection of Dehnegasse and Rosentalgasse, the Rosenbach is led over a length of 534 m as a brook canal until it flows underground in the Keißlergasse into the left Vienna river collecting canal. The brook channel has a gradient of 25 ‰ and runs around 4 m below the surface of the earth.

The Rosenbach carries water all year round. Its mean discharge (MQ) is 0.015 m³ / s. With a flood of the century (HQ100) 14 m³ / s are reached. At the Rosenbach there is a very high risk of flooding. In the event of a flood of the century, infrastructure and the resident population are affected to a very high degree.

history

The Rosenbach flowed into the Mariabrunn Mühlbach in the 18th and 19th centuries . Its lower course was therefore completely straightened by the middle of the 18th century. In the event of flooding, which the Mühlbach could no longer contain, water from the Rosenbach was discharged into a relief ditch at the Hacking mill , which flowed into the Wien River.

The later Dehnepark was laid out from 1791 to 1804 as an English landscape garden. The Rosenbach was relocated and regulated in this area. At the turn of the 19th to the 20th century, the lower reaches of the Rosenbach bulged. The Mariabrunn Mühlbach also disappeared into the sewer system.

ecology

The Rosenbach is a near-natural Wienerwaldbach . It is a habitat of the rare stone crab ( Austropotamobius torrentium ). Mayfly larvae and river flea shrimp can be found in the stream , which is evidence of its good water quality.

Pike , carp , red- eared slider turtles and signal crabs were released in the stretch park pond . However, these are predators of all amphibians , for which the pond has become uninhabitable. In addition, signal crabs transmit crayfish plague to stone crabs.

bridges

Upper Dehneparksteg

The Rosenbach is crossed by the following bridges, lined up in the direction of flow:

  • Temple Bridge: The 3 m long and 3 m wide stone pedestrian bridge was built in 1970.
  • Loiblbrunnenbrücke: The 10 m long and 4 m wide reinforced concrete road bridge on Loiblstrasse was built in 1927.
  • Kleibersteg: The 18 m long and 2 m wide steel pedestrian bridge was built in 1966.
  • Third Rosenbachsteg: The 5 m long and 2 m wide reinforced concrete pedestrian bridge was built in 1950.
  • Second Rosenbachsteg: The 4 m long and 2 m wide reinforced concrete pedestrian bridge was built in 1934.
  • Bridge over the Rosenbach: The 2 m long and 8 m wide reinforced concrete road bridge on Rosentalgasse was built in 1957.
  • First Rosenbachsteg: The 10 m long and 3 m wide stone pedestrian bridge was built in 1934.
  • Oberer Dehneparksteg: The 4 m long and 1 m wide pedestrian bridge made of steel was built in 1960.
  • Unterer Dehneparksteg: The 4 m long and 2 m wide wooden pedestrian bridge was built in 1990.
