The Brown Bach is an almost three kilometer long stream of Ellwanger Mountains in the district of Schwäbisch Hall in the northeastern Baden-Wuerttemberg , the majority in the municipality of Bühlerzell runs and just before the Avenmühle the community Buehlertann with the coming from the right Sauerbach the left Oberlaufast of Avenbachs merges .

geography

course

The brown brook arises in the northeast bay of the clearing island around Kammerstatt about 0.8 km from the hamlet on the edge of the forest on the Sauerberg to the Schälbühl Flurgewann at about 490  m above sea level. NHN . The stream initially runs west through a wide, slowly deepening hollow, mostly in the corridor near the edge of the forest in the north. After he has broken away from the forest, a tree gallery begins around him. He is now digging a blade in which the expanding forest will accompany him. It turns slightly to the west-northwest and passes a small waterworks. From the left and then from the right out of the Rappensturz small blade cracks run towards it, after the last open valley floor begins on the right under the first house in the hamlet of Holenstein on the slope. He passes a small fish pond on the right bank and then enters the Holenstein area, where his only significant tributary, Reutebach, flows down from the Frühmessholz from the left at the chapel .

He leaves the place in the course next to the K 2626 leading to Bühlertann- Kottspiel . Before the now sloping spur of the Ulrichsberg he changes the side of the road, passes a pond, there for the last hundred meters it crosses the area of ​​the municipality of Bühlertann and then flows, finally again in a westerly direction, at about 396  m above sea level. NHN with the coming out of the Sauerbach forest in northeastern Sauerbach the left roll call Oberlaufast of Avenbachs together. The right upper branch of the Avenbach drains a little further up a lake that is also fed by the Sauerbach. The branches of the receiving water flow together less than 200 meters further at the Avenmühle .

The Braune Bach ends after a 2.9 km run about 94 meters below its origin, its mean bottom slope is therefore about 32 ‰.

Catchment area

The brown brook drains an area of ​​about 2.2 km², which lies in the northwest of the lower natural area Ellwanger Berge of the Swabian-Franconian Waldberg . Here are the rocks of the Mittelkeuper , from the Stubensandstein ( Löwenstein formation ) down to the Gipskeuper ( grave field formation ). The stream rises in the transition area between the Stubensandstein and the underlying Upper Bunten Marl ( Mainhardt Formation ), a clayey storage layer from which it soon changes into the silica sandstone ( Hassberge Formation ). This is followed near the waterworks in its small forest canyon by the somewhat wider zone of the Lower Colorful Marl ( Steigerwald Formation ), whereupon it runs on reed sandstone ( Stuttgart Formation ) from around the beginning of Holenstein . Only shortly before the confluence in the meadow of the Sauerbach / Avenbach does it reach the Gipskeuper after this.

The greatest height of almost 505  m above sea level. NHN reaches the area at the eastern tip in the forest on the Sauerberg. From there, the right and northern watershed runs westward over the Ulrichsberg spur to the mouth, on the other side the left tributary Sauerbergbach and then the Sauerbach itself drain the other side of the ridge. On the Sauerberg there is a short border section to the Wolfsklinge , which runs roughly in the opposite direction to the Blinden Rot in the east. From the bend in the southern Sauerberg, the left watershed follows the ridge road axis to Kammerstatt (L 2628) and a little further in the direction of Bühlerzell (L 2627); outside the group stream competes with the upper Bühler . The left catchment area boundary then bends from the ridge and the road to the northwest approximately above the Reutebach springs and runs over the Anzenbach in the direction of the confluence with the Sauerbach; The only significant lower tributary, the Sperberklingenbach, of the Avenbach, which also runs to the Bühler, competes on this section .

There is a little more open land than forest in the area. The only place on the bank is Holenstein on the middle course. A small part of Kammerstatt is also on this side of the watershed in the south. Both hamlets belong to the municipality of Bühlerzell , as does almost the entire area, with the exception of just a strip near the mouth in the west of the Bühlertanner district.

Origin of the Brauner Bach at about 490  m above sea level. NHN about 0.8 km northeast of the Bühlerzell hamlet Kammerstatt on the southern edge of the forest on the Sauerberg to the open corridor of the Schälbühl . The stream flows in a slowly deepening hollow, mostly in the meadow, initially about west.

  • (Waldklingenbach), from the left and south to about 444  m above sea level. NHN near the waterworks in the forest east of Holenstein , approx. 0.1 km and approx. 0.1 km². Arises at about 460  m above sea level. NHN near the edge of the valley forest to the Gieß corridor .
    After that, the Brown Brook now flows west-northwest.
  • (Bach from the Rappensturz ), from the right and northeast to 435.6  m above sea level. NHN at the valley forest exit, approx. 0.3 km and approx. 0.1 km². Arises at about 465  m above sea level. NHN at the beginning of its woody secondary blade.
  • RiverIcon-SmallLake.svgFeeds at over 430  m above sea level. NHN a fish pond to the right of the run about 0.1 km before the first house in Holenstein, under 0.1 ha.
  • Reutebach , from the left and south-southeast to about 423  m above sea level. NHN in Holenstein am Wegestern near the chapel, 0.8 km and approx. 0.4 km². Rises at about 480  m above sea level. NHN about 0.8 km west of Kammerstatt in a spring trough protruding into the corridor as a waldeck.
    • (Another source arm of the Reutenbach ), from the right and south-east to about 465  m above sea level. NHN before the start of the steep blade section in the forest, approx. 0.2 km and less than 0.1 km². Arises at about 480  m above sea level. NHN about 0.3 km northwest of the small stone temple on the K 2627 Kammerstatt – Bühlerzell in the edge of the forest. About as long and catchy as the other namesake load.
    • (Muldenrinne at Burgstall Holenstein), from the left and south to about 433  m above sea level. NHN about 0.1 km before the first property in Holenstein, about 0.1 km and less than 0.1 km². Arises inconsistently below 460  m above sea level. NHN in the early measuring wood . In the corner of the mouth of the castle is Holenstein , the lost castle used the low spur of the mouth as a hill.

Confluence of the Brauner Bach from the left and finally east to about 396  m above sea level. NHN next to the K 2626 less than 200 meters before the Avenmühle with the Sauerbach coming from the right to the left upper branch of the Avenbach . The brown brook is 2.9 km long and has a catchment area of ​​approx. 2.2 km².

Nature and reserve

The Braune Bach flows naturally from the onset of its accompanying gallery to the local border of Holenstein. After the hamlet, trees again line its gently meandering course until the side of the road changes a little before the estuary. The eastern third of the catchment area is a water protection area .
