The Avenbach - [ ˈaːfn̩ˌbax ], in the dialect [ ˈaːfəˌbax ], so the V is to be spoken voiceless - is a 4.5 km long brook in northeastern Baden-Württemberg that flows into the Bühler from the right at Bühlertann -Kottspiel . Its more important left upper course is the Sauerbach .

geography

Source and history

The Avenbach arises under the upper course name Sauerbach about 0.8 km southeast of the center of the hamlet Bühlertann - Fronrot . Here it flows to about 483 m above sea level. NN from the outlet of a drainage pipe of the Bühl meadow valley between the L 1060 and the Spitalwald , which is part of the plateau of the Ellwang Mountains east of Fronrot. The first about 400 m of its course it pulls west and deepens quickly.

Then it reaches the field boundary to a wider meadow valley south of Fronrot and flows from here in a south-westerly direction. He initially runs on the left foot of the slope to the Sauerberg well above the valley depth line, between the forest edge on the left and right towards a dam towards his valley. Immediately after having passed the three fenced ponds of the Fronrot oxidation sewage treatment plant in the middle of the trough at a distance of about 50 meters, he is led back steeply into his natural bed, on this slope and a little above he has dug himself several meters deep into the terrain and doing so Tree roots washed free. For the next quarter of a kilometer, the left bank follows the edge of the hillside forest at a few paces, which is the municipal boundary between Bühlertann and Bühlerzell .

After more than a kilometer from the source, it takes its first major tributary from the left, the Sauerbergbach , which arises roughly in the middle of the eponymous mountain forest. Then the combined brook turns west to the Bühlerzell area and meanders through a meadow valley between the wooded banks of the river, between the Bühlerzell-Holensteiner Ulrichsberg in the south, whose steep parts on the upper slope today mostly cover the fallen fruit meadows and grassland, which are used for pasture, and the wooded Tollberg in the North.

Km to about 2.5, just switched back to Buhler Tanner municipality, it flows from the right from a small blade between the Toll Mountain and the underlying large plateau of the castle construction of the Great Mountain Trench to, in a humid lowlands about 300 m southwest of Buehlertann-Blashof, after which his name is only Avenbach . Then it divides into two branches, the right one, which turns to the southwest, flows into a 0.9 hectare lake east of the Kirchbühl , the left main branch southwards past the edge of the lake to merge with the one approaching from the direction of Holenstein from the left Braunen Bach , the longest of the Avenbach tributaries. In the corner of the mouth there is another, smaller lake, below this left branch turns to the west. At the Avenmühle it reunites with the right one a little over three kilometers below the origin.

Then the village connection road from Bühlertann-Halden crosses it in the direction of Holenstein. The remainder of the brook meanders between woodland on the banks to the west-south-west. To the right of it lies the long slope of the Laberich , at the beginning of which there is a large arable area in the lower part, followed by meadows that are partly separated by hedges and bushes. At the top, this slope turns into a middle step around the Bühlertanner Heuhof, which is plowed. Set even further back, the long spur on which the Tannenburg stands rises above Bühlertann-Halden .

On the left side of the valley, the slope is flatter and the first level of the terrain is lower, and it is also heavily used for arable farming. From this side, the left tributary Sperberklingenbach approaches from its eponymous forest blade between the forest mountains of Anzenberg and Eichberg rising behind the fields , which flows about 3.7 km below the Avenbach source. Finally, the Avenbach reaches the eastern boundary of the Bühlertanner hamlet of Kottspiel, crosses under the Bühlertalstrasse L 1072 and then runs on its southern edge to the bridge in the hamlet, where it is 4.5 km at about 377 m above sea level. NN flows into the Bühler from the right .

Catchment area

The Avenbach has a catchment area of 8.4 km², which in terms of natural space lies in the lower area of the Ellwanger Mountains of the Swabian-Franconian Forest Mountains . It extends from its 504.9 m above sea level. NN highest point on the wooded Sauerberg on the K 2628 to Kammerstatt to the mouth about 4.3 km to the west, across it it has a width of up to 2.5 km.

Its northern border stretches from the Tannenburg (Bühlertann) at the northwest corner on the Tannenberg , known as the western spur of the Ellwang Mountains, above the Bühlertal, eastwards through the long spur plateau of the castle building and through the largely inner hamlet of Fronrot to a waldeck on Zimmerbühl east of the Bühlertanner village, up to which the Dammbach also drains the other side spur slope westwards and a little further downwards to the Bühler , while east of the hamlet on the wide plateau outside the Forellenbach runs in the opposite direction to the Kocher inflow Blinde Rot .

In Zimmerbühl the border bends and follows the K 2628 first south and then west to Kammerstatt . Here right tributaries to the Blinden Rot from Höllholzbach down to Dollesbach are the otherworldly competitors. From Kammerstatt the further southern border, now following the K 2627, extends to the edge of the forest and then straight ahead on a forest path that begins there past the Bühlerzell farmstead Eichberg to the central Eichberg . On this section, the Bühler brooks Gruppenbach , Pfaffenbach and Dietenbach compete one after the other .

Then the border of the Avenbach catchment area runs northwest over the ridge of the Sefflensrain and through the Kottspiel Taubenäcker to the confluence with the Bühler at the bridge there; there are no significant rivers beyond the Bühler to compete on this stretch. From Kottspiel, the watershed ascends a first step in the terrain over the vineyard at the Bühlertanner hamlet of Heuhof , then turns southeast around the valley bay of the Bühler tributary Elsäßerbach , then crosses the hamlet of Halden to the north and reaches the Tannenburg on the front Tannenberg again in a steep ascent.

The larger part of the catchment area lies on the Bühlertanner district, the smaller on that of Bühlerzell. The hamlets of Fronrot (the larger southern part), Halden (eastern part), Blashof (whole) and Kottspiel (a small eastern sector) are in the catchment area of Bühlertann, as are the farms and single houses Kreidelhaus and Avenmühle. The only Bühlerzell settlement areas in it are the hamlets Holenstein (whole) and Kammerstatt (with the smaller northern part). Directly on the course of the Avenbach are only the Avenmühle on the lower reaches and Kottspiel on the estuary, the upper Sauerbach is completely uninhabited.

geology

Hassberge formation (lower silica sandstone), inclined stratification, directly above the marls of the Lehrberg strata, Sauerbachklinge near Bühlertann-Fronrot

The Avenbach with its tributaries has created a wide, roughly triangular erosion bay in the Mittelkeuper east of the Bühler between the mountain spurs of the Bühlerzeller Eichberg in the south and the Bühlertanner Tannenburg in the north , the north-eastern tip of which is in the western Fronroter Sauerberg . Its south-eastern edge areas are on the edge of the Stuben sandstone layer ( Löwenstein Formation ), which begins around Bühlerzell- Kammerstadt over Kieselsandstein and Oberen Bunte marls ( Mainhardt Formation ), while the northern areas on the southern slope of the silica sandstone plateau ( Hassberge Formation ) between Tannenburg in the west and Fronrot in the east ( Erbishalde and adjoining castle building ). The central part of the catchment area is mostly in the reed sandstone ( Stuttgart formation ); On both sides of the hollow of the Avenbach , which flows in the middle and lower part in the estheria layers of the gypsum keuper, there are large, somewhat curved or hilly areas in the reed sandstone, which are mostly plowed. To the right of the lowest valley, around the Bühlertanner Heuhof, there is an island of Unteren Bunten Mergels ( Steigerwald Formation ) on the reed sandstone , which otherwise stretches as a narrow strip on the slopes to the pebble sandstone surface, but can follow the stream for longer in the upper valleys. The leveling areas south of the lower valley lie in the layers of estheria or on the corbula bank of the gypsum keuper.

Sauerberg and Sauerbergbach arise at the edge of the silica sandstone plateau of the northern Ellwang Mountains , the large tributaries from the southeast ( Brauner Bach and its tributary Reutebach , Sperberklingenbach ) in the transition area between the Stubensandstein and the Upper Colorful Marls ( Mainhardt Formation ) or in these. The only larger right tributary, the Tollberggraben, of the main line from Sauerbach and Avenbach begins its course in the Lower Bunter Mergeln, at times also on the edge of the silica sandstone area. With the exception of the Brauner Bach , all the others reach the lower colored marl, which is rich in blades.
