The Aubach is a brook in Upper Franconia in the river systems of Mistletoe and Red Main , which flows into the Sendelbach from the left and south in Bayreuth .
Surname
The Aubach must not be confused with the upper reaches of the Tappert , which is also called Aubach in the neighboring towns from its source area to Thiergarten .
The Aubach is referred to as the Aubächel on a map from the 19th century .
geography
course
The Aubach rises in the south of the city of Bayreuth not far from the district Rödensdorf at the northeast foot of the Sophienberg at about 495 m above sea level. NN . It initially flows in a north-easterly direction and reaches today's urban area just below the source. The development of the Destuben district avoids the valley location because of the risk of flooding in spring, but the stream there only carries sparse water in summer. East of Destuben was 2017 to near Tappert About conductor applied. In the event of a flood, water can flow through it to its retention basin near Oberkonnersreuth .
In Karolinenreuth, the Aubach receives more water from an artificial pond in summer than it carries itself. At the Hohlmühle district, it turns to the northwest, here too water comes from a pond drain. In the past, he largely crossed under the adjoining area of the former parade ground south of the allotments of the same name in a closed canal. Apart from the street underpasses, this is open again and the stream in this area has been renatured. The two sandstone canal openings south of Universitätsstrasse and later west of Schwedenbrücke were preserved. The stream runs here for a short stretch from south to north in the ecological-botanical garden and flows into a backwater basin. From this it flows to the north-west, leaves the fenced area and runs along the allotment garden area “Parade ground” on the right bank through a meadow. Behind the old canal mouth, it crosses the gardens of the allotment garden “Schwedenbrücke” in a paved bed, after which it feeds another pond with a branch.
At the confluence of the Finsterweihergraben , which tapers from the south, it swings to the north and flows in the Röhrenseepark through the "C'est-bon-Tal" into the long Röhrensee . This approximately 1⅔ hectare reservoir, fed by the Aubach, is the largest standing body of water in the city. The Rohrweiher , one of its two predecessors, can be traced back to 1611 as a warehouse for wooden water pipes (" dykes "). Today the lake with its surrounding park, a boat rental, freely accessible animal enclosures, a beer garden and a large "cross-generational play area" is a popular local recreation area.
At the northern end it runs over a weir from the Röhrensee and initially flows a good 300 meters in an open direction, accompanied by a tree gallery, northeast. Shortly before the Wittelsbacherring, it disappears into an underground inlet nozzle and flows into it less than 100 meters further on the other side of the street from the left into the Sendelbach , which has been running in a closed canal here since the Wittelsbacherring was built.
Catchment area
The catchment area of the Aubach is about 8.8 km². Its southern tip with a little over 590 m above sea level. The highest point reaching the NHN is on the Sophienberg, its northern tip almost 6 km away at the mouth in Bayreuth; in between it widens like a kite to a width of about 3 km.
A small area around the southern tip is just in the Black Jura , after a narrow transition zone in the Feuerletten ( Trossingen Formation ), which runs close to the southwestern watershed, the vast majority of the catchment area is in the Sandstone Keuper . A fault runs along the Lias-Keuper border.
