The Tierbach is a 3 km long brook on the municipality marker of Oppenweiler in the Rems-Murr-Kreis in northern Baden-Württemberg , which flows from the right into the middle Murr after a somewhat westerly, generally southern course in the industrial area of ​​Oppenweiler in the floodplain .

geography

course

The Tierbach rises from the so-called source of sighs in the forest at about 429  m above sea level. NN , which is about 0.7 km east-southeast of Wilhelmsheim in the south-east of Waldgewann Greut near a parking lot and about twice as far to the north of the hillside settlement of Reichenberg . The young brook flows for the first half a kilometer west through the forest to a turning turpentine of the road that connects the village of Reichenberg across the upper valley with the central Oppenweiler. There, at around 370  m above sea level. NN , leads the only only about 0.3 km long tributary of some importance, a volatile stream from a short, southward current forest sword , immediately east of the Wilhelm home ground in Won Heiligenbrunnen starts.

At the inflow, the Tierbach turns to the left in the direction of the inflow on the south course through its wooded and steeply torn blade in sections, which only after about two thirds of the run to about 275  m above sea level. NN a little northwest and under the spur of Castle Reichenberg merges into a shallower valley basin. The brook now runs, still with small changes of direction, through orchards in the soft area of ​​the western valley settlement of Reichenberg around Tierbachstrasse and crosses it on a south-eastern course from there. After a short walk through the valley floor made of meadows and fields, he crosses under the Bundesstraße 14 called Sulzbacher Straße and then straightens through the industrial area in the flat right valley floodplain of the Murr between Reichenberg and Oppenweiler. At the bend in the riverside road, it finally opens at about 256  m above sea level. NN from the right into the middle Murr .

The Tierbach is 3.0 km long, has an average bed gradient of around 57 ‰ and flows into the source of sighs about 173 meters below its origin.

Catchment area

The catchment area of about 1.7 square kilometers dehydrated animal Bach is located in the Swabian-Franconian Forest Nature Park and on the western edge of the natural area Swabian-Franconian Forest to the next room Neckarbecken , more precisely to its subspace exterior Backnanger Bay . It is divided into a predominant part in the sub-area of ​​the southwestern Löwenstein Mountains and a smaller, estuary near the Murrtal . The stream is the last tributary of the Murr before it enters the Backnang Bay.

The little over 490  m above sea level. NN highest points in the catchment area are located on the equally high northern watershed to the Lauter tributary Marderbächle , which then descends along the northeast border in a ridge to the southeast to the area of ​​the Sighs, behind which the lowest valley of the largest Murr tributary "Spiegelberger “ Louder lies. Then the border in front of the catchment area of ​​the small Murr tributary Rossstallbach moves southwards on its spur down to Reichenberg Castle, from there steeply into the valley plain and flat to the mouth.

The western watershed, which rises northward over the Schiffrainberg spur , at the end through western Wilhelmsheim and back to the northwest corner on the sheath to the Marderbächle, borders on the neighboring catchment area of ​​the next Murr tributary Rohrbach ; In the lower area the Rohrbach itself competes outside, in the upper area its left tributary Hirtenbach .

The area is divided roughly in half into forest on the one hand and open land with settlement areas on the other. The forest is mainly in the north and northeast as well as in the Talklinge up to the end of the middle reaches. The largest contiguous piece of open corridor lies from a little south of the source of sighs down to the settlement at Reichenbach Castle on the spur wedge that separates the Tierbach valley from the Murrtal valley above the mouth. There is built-up terrain on the bank only on the lower reaches in the form of the western valley settlement of Reichenberg around Tierbachstrasse and the Oppenweiler industrial zone in the valley; Next to it is a large part of the high altitude settlement of Reichenberg, set back behind the castle in the catchment area, a separate group of courtyards in the hamlet of Schiffrain and most of the Wilhelmsheim site, all of which, like the entire catchment area, belong to the municipality of Oppenweiler .

geology

The catchment area of ​​the Tierbach lies in the area of ​​the Mittelkeuper layers of the southern Löwenstein Mountains . The highest layer is the Stubensandstein ( Löwenstein Formation ) on the watershed in the north and east of Wilhelmsheim zu Marderbächle and Lauter. After these upper colored marls ( Mainhardt Formation ), which border the southern edge in a band and in which the fountain of sighs is also located, the southward running spurs settle, in the west to the Schiffrainberg, in the east to the spur with Reichenberg Castle at the top, long southward continues, they are covered by the silica sandstone ( Hassberge formation ). In the Klingental of the creek in between, the lower colored marls ( Steigerwald formation ) are found on most of its area . The foot of the Burg-Reichenberg-Sporn is surrounded by a narrow strip of gypsum keuper ( Grabfeld formation ), then the floodplain sediments of the wide right valley plain of the Murr begin, while the southern tip of the Schiffrainberg, somewhat separated from the stump of the Sporn to the Rohrbach, with that for the neighboring Backnang basin typical loess sediment is covered by quaternary deposits. To the Murr, the Tierbach and neighboring Rohrbach have deposited two cones that merge into one another.

The Neckar-Jagst-Fuche runs through the catchment area from west -south- west to east-north-east , a far-reaching subsidence zone with a corresponding fault line across the valley, which comes from the alder blade west of the Rohrbach, touches the southern end of the Schiffrainberg and then settles in the saddle depression behind the spur tip of Reichenberg Castle continues in the east of the Tierbach; the Hochscholle is here on the south side. Two further, roughly parallel fault lines with reverse steps are suspected further north. A fourth, now west-north-west-east-south-east over the Hahnbühl ( 395.9  m above sea level ) on the rear Reichenberg-Sporn with again stepping from south to north is proven.

Nature and protected areas

Large parts of the catchment area are in the Rohrbachtal and Reichenberg nature reserve .
