The Bärenbach is a little less than a kilometer long brook in the Sulzdorf district of Schwäbisch Hall in the Schwäbisch Hall district in north-eastern Baden-Württemberg , which flows into the Bühler from the left at the Sulzdorf hamlet of Buch .

geography

course

The Bärenbach arises a stone's throw to the north of the community boundary on the field path at the end of the Bärenbach settlement in the small town of Vellberg on the Sulzdorf district mark at around 392  m above sea level. NN . Here its course begins in a meadow valley basin that is not yet deep as an initially northeastern ditch with no vegetation. This soon turns to the left and then runs along a fairly broad valley floor to the north-north-west next to the K 2602 district road, on the right bank lies herbaceous wasteland, on the steeper left bank the course is accompanied by bushes.

Where it reaches the roadside after a total of almost 400 meters, flows from the left and west-southwest to just under 380  m above sea level. NN a not much shorter left source branch, which is also about 392  m above sea level. NN and on the field path from Buch to Bühlertalstraße L 1060, it is accompanied in sections by a tree or bush gallery.

The combined stream flows resistant northeast, passes under this same county road, happened beyond an old waterfront cottage and then plunges into a narrow, wooded and rocky pathless sword on Bühlertaleinschnitt over limestone benches quickly to the valley. At just under 327.4  m above sea level. NN it then flows across the Bühlertal hiking trail close to the river bank, where it is sometimes quite dry in summer, from the left opposite the Vellberger Lindenberg, which is surrounded in a left loop and a little upstream of the Buch viaduct of the Heilbronn – Crailsheim railway line in the lower section of the Bühler .

The 0.7 km long Bärenbach runs about 64 meters in altitude to its mouth with an average bed gradient of around 90 ‰. On its lower section, which is only about a third of a kilometer long from the district road crossing, it is even over 150 ‰.

Catchment area

The Bärenbach drains about 0.5 km² of the Vellberger Bucht sub-area belonging to the Hohenloher and Haller Ebene natural area , which includes the Keuperstufenrandbucht of the Bühler, approximately northeast of the lower Bühler. The with about 403  m above sea level. NN highest point in the catchment area is located in the far south on the western edge of the settlement of Vellberg in the Kreuzäckern . On the shorter right watershed in the east from here to the mouth, a smaller Bühler tributary competes above the spur of the Vellberger Stöckenburg , which dries up even more frequently in its blade. The left one runs from the highest point to the west-north-west and separates it from the catchment area of ​​the Steinbach , which flows further above at Eschenau , then it moves north-north-east towards Buch and separates from the drainage area of ​​the Hirtenbach , which flows below , both of which are more important Bühler tributaries.

In the catchment area there are geological layers from the lower Mittelkeuper down to the upper Muschelkalk . The Gipskeuper ( Grabfeld formation ) is located on the south and west edge on the ridge in front of Steinbach and Hirtenbachtal and in a tiny layer island on the Bärenberg to the right of the lower reaches. Both spring branches begin their course below in the Lettenkeuper ( Erfurt Formation ) of the Unterkeuper , the layer with the largest area share. The Upper Muschelkalk only sets in in the steep and short blade down into the Bühlertal.

The vast majority of the high plains along the corridor initially only dips slightly towards the edge of the Bühler Valley and is dominated by fields, while the little grassland lies in the valley basin. In the southern Bucher Weichbild there are also old high-stem fruit meadows. Forest only stands in the small blade, which is initially lined with wood.

From its circular road crossing the bear creek running in the landscape conservation area Bühlertal between Vellberg and Geislingen with side valleys and adjacent areas , which then will connect to the blade edge nature reserve Bühlertal lower passes.
