The Rautwiesenbach is a stream less than a kilometer long on the eastern edge of the village of Sulzdorf in the town of Schwäbisch Hall in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the lower Erlenbach from the left after about north-north-east on Bucher Strasse .

geography

course

The Rautwiesenbach arises less than a hundred meters east of a riding hall on Sulzdorfer Herdstraße at about 383  m above sea level. NHN in a small spring pot with duckweed under a group of willows. This stands in a round, herbaceous overgrown basin; Since the equestrian facilities were built, the growth zone, which stands out especially in autumn, has shrunk towards them. The spring, which is not necessarily strong even in summer, but constantly pouring out, flows northwards at a distance from a wood-working company on the outskirts, accompanied by initially only sporadic and low growth of trees and hedges. Soon the stream running between fields in the Gewann Sauhöhe in fairly flat terrain is followed by an agricultural branch path.

It crosses under the Heilbronn – Crailsheim railway line and turns north-east in front of the younger settlement around the Kresswiesen road. The accompanying vegetation in its now deeper natural hollow widens to a small alluvial forest, at the end of which it is a little below 367.5  m above sea level. NHN on the edge of the L 2602 Sulzdorf– Buch ("Bucher Straße") flows from the left to the Erlenbach , which is much longer here and then continues in the last direction of the Rautwiesenbach.

The Rautwiesenbach flows after a 0.7 km long path with an average bottom gradient of about 22 ‰, about 16 meters in altitude below its source pot. It has no significant inflows.

Catchment area

The Rautwiesenbach has a catchment area of ​​around 0.4 km². With a small uppermost forest gusset, it has, in terms of natural space , part of the sub-area Limpurger Berge of the Swabian-Franconian Forest Mountains , but the far larger remainder and the entire course lies in the natural area Hohenloher and Haller Ebene and more precisely in its sub-area Vellberger Bucht . The highest proportion of the area is in the southwest of a wooded area, up to 427.3  m above sea level. The spurs of the Hehlberg reaching the NHN , on which there is a water reservoir.

The upper and middle catchment area with the origin of the stream lie in the Gipskeuper ( Grabfeld formation ). After about a third of its way, the stream changes to the Lettenkeuper ( Erfurt formation ) below, where it also flows.

In the west and north-west, the catchment area borders on that of the Schwarzenlachenbach , in front of which there are large residential and commercial areas of Sulzdorf without open natural watercourses. In the east, the upper reaches of the Erlenbach , which takes up the Rautwiesenbach and flows into the lower Schwarzenlachenbach, competes .

The whole area belongs to the Sulzdorf district marking. Settlement or development is only to the left of the Rautwiesenbach in the form of the industrial zone around Sulzdorfer Herdweg (K 2627) and the newer district around Kreßwiesen street, both times with a certain distance.

Nature and protected areas

The runoff below the source shows earlier trench-like course, here a grass path crosses it, later a well-developed dirt road before the railroad crossing. On the greater part of its way, however, the Rautwiesenbach shows a comparatively natural picture, measured against the nearby town limits.

The source pot is a natural monument. The smaller upper parts of the catchment area south of the L 1060 are in the nature reserve northern part of the Limpurger Mountains with slopes and parts of terrain between Hessental and Sulzdorf . The valley basin down the railway line is located in the Bühlertal nature reserve between Vellberg and Geislingen with side valleys and adjacent areas .
