The Marienbach is a brook in the 13th district of Hietzing in Vienna . It is a feeder of the right Vienna river collecting canal and is partly managed as a brook canal .

course

The Marienbach has a length of 1240 m with a height difference of 149 m. Its catchment area is 0.3 km².

The stream rises on the Baderwiese in the Lainzer Tiergarten nature reserve , not far from the Wienerblick viewpoint. From there it runs eastwards. Within the nature reserve, it is a dry valley that usually only carries water when it rains. The Marienbach leaves the Lainzer Tiergarten through a passage in the Tiergarten wall. It then flows in the Ober St. Veit district under the Hubertustürlsteg pedestrian bridge built in 2001.

From the upper end of the Schweizertalstrasse, the Marienbach is led as a brook canal. The canal is 1,440 m long and 4 to 5 m deep. It has a gradient of 14 to 66 ‰. The canal flows under the Schweizertalstraße - where it takes up the Veitlissengraben on the left - and the Firmiangasse, at the intersection of which with the Hietzinger Kai it flows underground into the right Vienna river collecting canal .

At the Marienbach there is no longer any risk of flooding. In the event of a flood of the century (HQ100), neither the infrastructure nor the resident population are affected. With an HQ100 it reaches 2.8 m³ / s.

history

The Marienbach used to flow above ground through the settlement of Ober St. Veit, which has existed since the 12th century. In the town center, its course was changed and straightened several times between 1755 and 1825. The Wien River , into which the stream originally flowed directly, shifted its course further south between 1780 and 1825, which shortened the Marienbach. Until 1875 the brook in Ober St. Veit was arched over a length of 400 m. However, the structure could not absorb the water from feeders such as the Veitlissengraben in heavy rain.

The Marienbach caused floods for centuries. The last devastating flood occurred on June 1st, 1898. The water was dammed by driftwood at the passage of the Tiergarten wall until it broke. The subsequent flooding of Ober St. Veit claimed one life. The Marienbach canal was subsequently built in 1907 and 1912. It was completed on March 1, 1916. As a result, the settlement areas, where vineyards used to be, expanded to the wall of the Lainzer Tiergarten.

ecology

At its origin on the Baderwiese, the Marienbach forms a spring pool . The swamp vegetation is characterized by gray-green rushes ( Juncus inflexus ), and water irises ( Iris pseudacorus ) thrive here . In some places in the pool there are wallows .
