The Rotbach is a nearly two and a half kilometer long stream in the Sulzdorf district marking of Schwäbisch Hall in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the lower Schwarzenlachenbach from the left between Sulzdorf and the associated hamlet of Anhausen and altogether west-north-west .

geography

course

The Rotbach arises approx. 350 m south of the outskirts of Schwäbisch Hall- Matheshörlebach between large fields on a group of trees on the west-east moving field path called Hallweg in its ditch at about 386  m above sea level. NHN .

Alongside the path, it flows eastwards and after about half a kilometer it crosses under the K 2601 Matheshörlebach-Sulzdorf in a still very shallow basin with even sparse and sometimes intermittent water. On the other side it continues its course in the same direction as a dirt road for about one and a half times as long between fields, now accompanied by a thin chain of trees, until it has crossed the K 2627 Jagstrot –Sulzdorf in a more noticeable hollow in the terrain.

After that, the dirt road, creek ditch and the now deepening valley bend to the southeast. Half a kilometer further, the cul-de-sac from Sulzdorf to Hohenstadt crosses the course in the northeast. Then the accompanying wood widens to a narrow strip of alluvial forest between a newer settlement area on the outskirts of Sulzdorf around the ring road Am Rotbach on the right and an Aussiedlerhof up on the left Asmusrain slope . On this section, now unaccompanied by a paved path, some drainages run under the tall alders to the creek bed, which is up to meters wide, meandering and up to two meters deep into its valley floor, at the mouth of which sintered limestone has deposited.

This pathless section ends after less than half a kilometer, and the stream then runs to the right of the public connecting road from Sulzdorf to Anhausen, which descends over its valley into that of the Schwarzenlachenbach. There the brook plunges down several times over steps that have become round humpings due to sinter deposits and are up to two meters high. After a good two hundred meters of this steepest section of the valley, the Rotbach flows out at almost 339.9  m above sea level. NHN from the left into the Schwarzenlachenbach , last approaching from the southwest , which flows into the Bühler after less than a kilometer after the remaining eastern course in Anhausen .

After a roughly 2.3 km long run with an average bed gradient of about 20 ‰, the Rotbach flows to the Schwarzenlachenbach about 46 meters below its origin.

Catchment area

The Rotbach has a catchment area of ​​around 1.6 km² which, in terms of natural space , belongs entirely to the sub-area of ​​the Haller level of the Hohenloher and Haller level . The with about 399  m above sea level. NHN highest point in it is on the northeast corner south of Jagstrot. The area, which is quite flat except for the lower Bachklinge, is mostly used for arable farming in large fields, the settlement is limited to a few older houses on the north and north-east edge of Sulzdorf and above all to the newer settlement on the right of the lower course around the street Am Rotbach.

In most of the catchment area, the Lettenkeuper ( Erfurt Formation ) is located, in which the stream arises and remains until the pathless section between Hohenstädter and Anhäuser Strasse, where it then changes into the Upper Muschelkalk , into which it also flows. In the right curve of the stream on the northern edge of Sulzdorf Gipskeuper ( Grabfeld Formation ) is located, with a small loess sediment island from Quaternary deposits on it near the sports hall. A longer strip of loess sediment lies on the flat left slope of the valley from the middle reaches. At the top of the spur leading to the Schwarzenlachenbach stream sits a small, abandoned shell limestone quarry with a five-meter high quarry wall and a small Küstnersgumpen quarry pond . At the bottom of the spur in a noticeably deep valley, the topographic map also shows a dismantling wall; In nature, from the upper quarry down, you see a lot of rock rubble that may hide earlier mining.

The following neighboring streams compete in turn:

Origin of the Rotbach at about 386  m above sea level. NHN approx. 350 m south of the outskirts of Schwäbisch Hall - Matheshörlebach at a group of trees on a west-east moving dirt road. The stream initially flows eastwards.

  • (Ditch from the Jagstroter Strasse), from the right and west to about 376  m above sea level. NHN approx. 200 meters before Hohenstadter Straße, approx. 0.2 km. Arises at about 383  m above sea level. NHN . Inconsistent.
  • (Ditch from the Jagstroter Straße), from the right and west to about 373  m above sea level. NHN a few steps before Hohenstadter Strasse, approx. 0.3 km. Arises at about 385  m above sea level. NHN . Inconsistent.
  • (Slope from the Asmusrain ), from the left and northeast to about 365  m above sea level. NHN at the entrance of the Anhäuser Straße in the Rotbach-Klinge, about 0.1 km. Arises at about 378  m above sea level. NHN east of the Aussiedlerhof on the Ansmusrains. Inconsistent discharge in a field hedge.
  • RiverIcon-SmallLake.svgAt about 365  m above sea level. NHN is located in an abandoned small quarry of the Küstnersgumpen, with no outflow on the surface, on the spur of the mouth of the Rotbach to the Schwarzenlachenbach, under 0.1 ha. According to the official waterway map, it is in two parts, but in nature there is a contiguous pond.

Mouth of the Rotbach from the left and finally northwest to almost 339.9  m above sea level. NHN at next to the road Sulzdorf - Anhausen in the lower Schwarzenlachenbach . The stream is 2.3 km long and has a catchment area of ​​around 1.6 km².

On an older topographical map, a 0.4 km long stream flows into the Rotbach and south-south-west shortly before its bend to the south-east in a strip of meadows, of which, however, nothing can be found in today's fields. Apparently, in connection with the large-scale land consolidation, there was also heavy drainage and this small stream was moved underground.

Nature and protected areas

Almost the entire catchment area of ​​the Rotbach is a cleared arable landscape. The valley basin from Hohenstadter Straße belongs to the Bühlertal nature reserve between Vellberg and Geislingen with side valleys and adjacent areas .
