The Gutleuthausbach is a stream in Tübingen , the at Berliner Ring springs and parallel to the North ring south through the Tägles blade to Bunting flows. A section of the north ring , completed in 1961, ran through its valley, and for this reason it is now canalised for almost its entire length.

Surname

The stream is named after the former Gutleuthaus, today's Pauline-Krone-Heim , which has been used as a hospital for infirmaries and poor for centuries outside the city gates since the Middle Ages.

geography

course

The Gutleuthausbach arises on the southern edge of the Berliner Ring in Tübingen at an altitude of about 455  m above sea level. NHN . It only flows fairly naturally on the 250 m long upper section. Its valley is characterized by a large flow gradient and natural falls north of the sandy path . Further erosion in the bed area is reduced or prevented by the existing rock. Local erosion continues to take place on the embankments. On the remaining section - below the flood dam - the stream is channeled underground.

On the first third of its course it flows to the south-east and crosses under the Tübingen north ring. There is a flood retention basin at the creek, which acts as a receiving water, at the level of the confluence of the sand path with the north ring, which runs here as a valley road . In the course of an in-depth safety review, it was found in 2013 that the operating space of the basin was not being optimally used. Because of the large runoff, it would only be 65% full even in the event of a flood of the century . The plant also had safety deficits.

Below the retention basin, the route of the north ring follows the south-facing valley in which the Gutleuthausbach flows underground. After the intersection with Wilhelmstrasse , the stream runs a little further south and throws under Köstlinstrasse .

After its 1.6 km long run with a strong mean bottom gradient of about 82 ‰, the Gutleuthausbach flows about 135 meters below its source at the bridge of Köstlinstraße opposite the Österberg at about 320  m above sea level. NHN from the left into the lower bunting .

Catchment area

The stream has a catchment area of ​​1.7 km², its highest point between Heuberg and Waldhausen at about 491  m above sea level. NHN is in the far north. In terms of natural space , it is part of the Tübingen step edge bay , which is counted as part of the Schönbuch .

On its north and east side the more important Goldersbach competes with the Ammer, on its west side first the Öhler over the Käsenbach , then the Iglersbach also competes with the Ammer.

geology

The brook still rises in the Psilonotenton formation of the Lower Jurassic , but runs predominantly in the Keuper , only briefly in the Räthsandstein ( Exter Formation ) of the Oberkeuper, then in the Mittelkeuper longer in the tuberous marl ( Trossingen formation ), the longest in the Stubensandstein ( Löwenstein) Formation ). Then it buried itself down to the floodplain of the Ammer through the deeper central Keup layers to the Gipskeuper ( grave field formation ). It ends in the Holocene alluvial clay band around the bunting. In the far north there is still Angulate sandstone formation above the Psilonotenton , above that on the northwest corner of the catchment area loess sediment from the Quaternary is deposited in a layered island, a smaller one on the right flank of the valley next to the lower course on Stuben sandstone.

history

The source of the fountain of Gutleuthauses Tübingen was in the 19th century Lustenauerstraße denunciation, which led to disputes between Tübingen and Lustnau.

In the 19th century, Karl Eduard Paulus found a wood wasp parasitic wasp ( Rhyssa persuasoria L. ) there.
