geography

Headwaters

The Steinbach arises about 1.2 km north-northeast of Obersontheim- Herlebach on the Sulzdorf district of the city of Schwäbisch Hall on the K 2627 Herlebach-Sulzdorf. The source is about 438 m above sea level. NHN in the Höning forest , which stretches along the eastern slope of the small mountain ridge Birkentöbele . From there it flows in a Mulden valley in the forest between the Burkhart foothills in the north and the first ascent to the mountain plateau a little further south in the east-northeast and is soon accompanied by a forest path. After about 0.6 km it takes its first inflow from the right at a side path confluence, which arises in a similar location only about 0.1 km south of it on the K 2627 and on its somewhat longer path from the right is temporarily fed by some Klingenbach streams .

course

After about 0.9 km, the Steinbach reaches the Dörrenzimmern golf course at the tree line, where it meanders through the Hättelenswiesen, accompanied by a row of gaps in the trees and in a widening meadow hollow that can hardly be called a valley. After about 1.3 km it feeds a 0.3 hectare artificial pond, which is also fed by the flat right-hand slope. After about 2.3 km run - meanwhile it is already on the other edge of the golf course - it turns in front of the L 1060 ("Bühlertalstraße") Sulzdorf – Bühlertann to the south-southeast and then about 0.2 km later takes a 0.7 km long inflow from the right from the Hart , which previously fed a 0.2 hectare pond on the golf course.

Now he runs along the right edge in a slow eintiefenden hollow between the distant L 1060 left and right accompanying dirt road through the pelvic meadows , accompanied, especially right where the river embankment is steep of wood. In this section it was apparently once straightened, at its end it was later placed again in a curve drawn as if with a compass. At this point, the 0.4 km long Ofenbach , which runs along a dirt road and which sometimes reaches a length of almost 1.0 km when it arises further up on the edge of the Sandrain forest, flows to it from the right .

Immediately afterwards, and now 3.2 km below its source, the brook crosses under the L 1060, passes the Vellberg development area around Markgrafenallee on its left slope to the south and is crossed by an asphalt field path. After about 4.0 km, the 0.6 km long Rohrbach flows from the right , which also runs as a ditch next to a dirt road. Around here the Steinbach begins to dig a valley trough between the upper slopes of the slope that is not even 100 meters wide and at the end 50 meters deep.

Soon a hiking trail leads across the Mulde over an old concrete footbridge. Here you can no longer see the upper slopes from the hollow, which is lined with trees on the slope, the stream has now lived up to its name and flows over shell limestone banks, small rock walls then come to its bank and the hollow is filled with forest. A hiking trail branches off from the footbridge and leads a few steps next to the Steinbach to the valley, which is increasingly becoming a gorge, which is called Taubenloch in the lower part .

Behind the right slope, not visible from the natural valley, shell limestone is broken in a large pit, the bottom of which is deep under the bed of the Steinbach, in the Ummenhofen quarry. After a total of 4.7 km a total of approximately eastward, the Steinbach flows out at a little below 348.6 m above sea level. NHN a few steps next to another old concrete footbridge over which the hiking trail continues through the floodplain to Vellberg-Eschenau, from the left into the middle Bühler . The brook empties about 89 meters below its origin and has a mean bed gradient of around 1.9 ‰.

Catchment area

The Steinbach has a nearly 4.0 square kilometers large catchment area, which in nature spatial observation with almost the upper half in the subspace Limpurger mountains of Schwäbisch-Franconian Forest is located, with the remainder in the subspace Vellberger bay of Hohenloh and Haller level . Its highest point is on the southwest corner at just under 480 m above sea level. NHN near an old water reservoir on the southern spur of the Birkentöbeles .

On the upper reaches of the north it borders on that of the Schwäbisch Hall - Dörrenzimmerner Hirtenbach , from the bend after the golf course briefly on that of the small Bärenbach , which runs roughly on the municipal boundary between Schwäbisch Hall-Buch and Vellberg , both move to the nearby Bühler . In the east and southeast this competes itself, in the south the Obersontheim - Ummenhofener Rossbach , which reaches the Bühler via the Obersontheim-Untersontheimer Riedbach . In the southwest and west, the watershed runs over the ridge from Berg and Birkentöbele to Fischach , which stretches across to the upper Bühler.

There is no settlement anywhere directly on the banks of the Steinbach , but the newer parts of Vellberg are to the left before and after the L 1060 has been crossed on the upper slope.

The larger part of the catchment area around the middle and lower reaches lies in the area of Vellberg, the slightly smaller part around the upper reaches in the area of Schwäbisch Hall. Obersontheim only has small spandrels in the south and west, where the municipal boundary deviates a little from the watershed, as well as an approximately 0.1 km² area on the western edge of the Ummenhofen quarry.

Tributaries

List of tributaries and lakes from source to mouth. Length of water, lake area, catchment area and altitude according to the corresponding layers on the LUBW online map. Other sources for the information are noted.

Mouth of the Steinbach to a little below 348.6 m above sea level. NHN from the left in Taubenloch about 0.7 km southwest of Vellberg- Eschenau next to an old Bühlersteg made of concrete from the left into the Bühler . The Steinbach is 4.7 km long and has a catchment area of almost 4.0 km².

geology

View to W into the pit of the Ummenhofer quarry in the Upper Muschelkalk, which with its long side on the right (heaped heap) reaches close to the Taubenloch.

The headwaters of the Steinbach are surrounded in the west and south by the reed sandstone plateaus ( Stuttgart formation ) of mountain and birch pots , the stream itself rises below in the upper Gipskeuper ( grave field formation ). Burkhart in the north and the first step to the mountain in the south are formed by the leveling areas of the Corbula-Bank des Gipskeupers. With its change of direction on the L 1060, the stream reaches the Unterseuper and, for example, at the tributary of the Rohrbach, the Upper Muschelkalk , into which it also flows.

Uphill, in continuation of the stream from the Hart , on the western edge of the Hohenrot forest to the meadow corridor, there is a sinkhole zone in a depression that has no drainage above ground and is covered by a constantly moist meadow in its corridor.

The Ummenhofer quarry to the right of the Unterlauf opens up the Upper Muschelkalk and the Lower Keuper .

Nature, landscape and protected areas

Until it reaches the golf course, the Steinbach and its right source branch flow through a closed forest area, which is followed on a first elevation level right below the mountain over 0.7 km a nowhere 0.2 km wide forest clearing. The wide valley basin is then covered by grassland almost to the bend in front of the L 1060, after which there are fields on the hills on both sides of the now narrower, green valley basin, with the exception of the Vellberger settlement on the left on the hill at the lower middle course and a shorter section on the right between Rohrbach inlet and the quarry, where there are smaller plots with open garden plots. In the narrow gorge of the Taubenloch stands Klingenwald, away from the rocky areas the arum grows on the black soil . The quarry pit accompanying it on the right is almost 0.8 km long in the direction of flow of the brook, its base area is larger due to further excavation despite partial backfilling.

The larger part of the upper Steinbach course up to the corridor boundary, including the entire right source branch, is a semi-natural alluvial forest under biotope protection, as is a forest and hedge bar running right to the bank just before the golf course pond and 0.2 ha of the sinkholes -Depression. A significantly larger area of this is a natural monument, as well as the above-mentioned wood bar and the Kraftsee , a wetland on a flat hill to the right of the middle course on the northern edge of the Hohenrot . A natural monument is also a wooded ravine near Ofenbach in the corridor, street fields as well as the field hedge mentioned in connection with the Rohrbach . The Taubenloch is under biotope and nature protection (nature reserve Unteres Bühlertal ).
