The Baierbach is a three kilometer long creek in the municipality of Michelfeld in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the middle Bibers from the right and west about two kilometers before it reaches the outskirts of Michelfeld .

geography

course

The Baierbach arises at about 477  m above sea level. NHN in a field path fork of an inconspicuous grass ditch east of the local border of the Michelfelder hamlet of Neunkirchen , which runs east-south-east next to one of the field paths, a direction that the water essentially maintains up to the mouth. After just fifty meters, the ditch, which is then partially enclosed with a concrete channel, is accompanied by a wood.

About 300 meters after the start of the watercourse, it reaches the edge of the forest at the Gewann Lochfeld and then flows between the Halmahd tubs on the left and Rotwald on the right in a more and more deepening valley, now as a natural, one to one and a half meter wide, somewhat meandering stream, mostly mixed Forest. It is reinforced by stratified springs on the slope, runs in a bed of rubble to sandy, sometimes muddy, and has flat and steep banks, next to which it is usually accompanied by a strip of deciduous trees.

Links that solves Baier Bacher wood the Halmahd off, then empties after about one and a half kilometers from the southwest from the direction Witzmannsweiler the only significant inflow Verrenbergbach , a self-not even a kilometer long forest stream, the right hand from the high-level foothills of Verrenbergs is accompanied. A little afterwards the forest on the slope to the left of the Baierbach ceases to exist , the Baierwiesen now lying there are grazed, while the Verrenberg, opposite, continues for a while to the bank.

About half a kilometer after the opening of the corridor, the water passes the Baierbach farm in a small pond on its southern edge, after which the now forest-free slopes on both sides quickly drop into the wide valley to the right of the Bibers. Before the foot of the Verrenberg hillside, the brook crosses under the state road L 1046 Gnadental – Michelfeld not far from the Michelfelder Hof Hahnenbusch and then travels its last half kilometer approximately eastwards alongside a somewhat angular field path through the Heimatwiesen, accompanied by rows of trees . At about 362  m above sea level. NHN it flows between the Michelfelder single farms Baumgarten and Mäurershäusle at the nearer foot of the opposite slope of the floodplain from the right into the middle Bibers , a little less than two kilometers before it reaches the outskirts of Michelfeld shortly before the bridge over the Bundesstraße 14 in the village.

After a run of about 3.0 km, the Baierbach flows around 115 meters below its origin, giving it an average bed gradient of about 38 ‰.

Catchment area

The Baierbach has a catchment area of ​​around 1.7 km², which, viewed in terms of natural space , lies in its western and central parts in the Waldenburg Mountains sub-area of the Swabian-Franconian Forest Mountains and with the eastern and estuary in the Haller Bay sub-area with the rose garden of the Hohenlohe and Haller levels .

The 486.3  m above sea level. NHN highest point reached is on the southwestern watershed near Neunkirchen. Beyond this long total watershed section on the plateau of the Waldenburg Mountains, the stream from the Kirschenklinge , the Katzenbach and the Köhlersbach flow from the right to the upper reaches of the Kocher tributary Ohrn from southeast to northwest . In the north, the Schöppklingenbach is the next upper, in the south the Erliner Bächle is the next lower right tributary of the Bibers , which feeds the Kocher far above the Ohrn.

On the plateau in the west, the landscape is open and mixed with fields and meadows. The large central part of the catchment area is mostly in mixed forest. In the small bay along the stream, which begins half a kilometer before Hof Baierbach, there are pastures. The lower course in the Bibers valley is accompanied by grassland, which is bordered by fields at a short distance.

The only settlement in the catchment area is the Baierbach farm just before the Bibers valley plain. Outside close to it are the Hahnenbusch farm on the right foot of the Biberstal slope and the hamlet of Neunkirchen in front of the north-northwest tip of the catchment area on the plateau. The whole area and all named places belong to the municipality Michelfeld .

Tributary and lake

  • Verrenbergbach , from the right and southwest to just under 396.2  m above sea level. NHN at MOUNTAIN, 0.9 km and almost 0.5 km². Rises from a source at about 480  m above sea level. NHN at the tree line of the main fields about 0.5 km northeast of the outskirts of Michelfeld- Witzmannsweiler .
  • RiverIcon-SmallLake.svgFlows through to something below 380  m above sea level. NHN a pond dammed behind a crossing at Michelfeld- Baierbach , less than 0.1 ha.

geology

The Baierbach is a brook in the Keuperbergland, the entire catchment area of ​​which lies in the Mittelkeuper . It arises on the Stubensandstein plateau ( Löwenstein Formation ) around Neunkirchen and, on its course, first penetrates the layers of the Upper Bunten Marl ( Mainhardt Formation ), the silica sandstone ( Hassberge Formation ), the Lower Bunten Mergel ( Steigerwald Formation ) and - before the tributary of the Verrenbergbach - the reed sandstone ( Stuttgart formation ). Where its valley opens on one side for the first time, there is the even deeper Gipskeuper ( Grabfeld Formation ) on the lower slopes , the deepest Mesozoic layer in the catchment area, while on the valley floor there it already runs in a strip of floodplain sediment from much more recent geological times. This also accompanies its lower course in the wide Biberstal, where terrace sediments lie next to it, which the beaver, which today flows hard to the left in its valley level, has left behind in front of the right slopes.

Nature and protected areas

The open valley bay of the Baiersbach with the Baierswiesen and the Geißberg to the left above are located in the Upper Biberstal landscape protection area, including the peripheral areas that the lower reaches of the stream then border in the Biberstal to the south. In the Steigwäldle am Bergsporn immediately northwest of the Baierbach farm, ravines , a forest edge and the hillside forest are designated as a natural monument; in the north on the spur height on the western edge of a clearing there is another natural monument that protects a southward section of the former Haller Landheeg once turned to the east in the Steigwäldle.
