Its left and official upper course is 1.4 km long and has an approx. 1.1 km² sub- catchment area, its right upper course is the Blümelbach .

geography

course

The Rittersbach arises at about 363  m above sea level. NHN on the southern edge of the rose garden hamlet Raibach at a field lane crossing as a ditch next to one of the farm roads. This soon joins the K 2594, which leads from Hohenholz to the B 19 in the direction of Schwäbisch Hall, and the Rittersbach crosses under the county road in an easterly direction. He now begins to initially slowly digging into its cradle, a the stream accompanying tree gallery sets in, the stream crosses also the B 19, then flows constantly about east-north and its valley develops into the forest blade between the bathes Lächleräcker left and Mittelbühl right .

From the blade he emerges into the low-lying corridor landscape around Tullau, which is embedded like an amphitheater in the round of the steep slopes from the high elevations. There, accompanied by a gallery of trees , he soon records the course of his only tributary, Blümelbach, from the right; the bed of both bodies of water is two to three meters below ground level. Then he passes the low hump of the Steinbühl on his left. It reaches the outskirts of Tullaus, where it disappears in a hollow, over the beginning of which a striking, narrow, about two dozen meters long rural garden is laid out.

In the further, the trenching follows the route of Kirchgasse running in the deepest trough and soon passes Tullau Castle on a low hill on the right , a public trough fountain on the left in the corner of the approaching Wirtsgasse and the Wolfgang Church on the right at street level . Finally, it crosses the L 2597, which opens up the hamlet and is called Mühlstraße in the village , and then flows straight to about 287  m above sea level. NHN from the left into the local Mühlkanal to the left of the middle stove .

The Rittersbach has a 2.2 km long run with an average bottom gradient of about 36 ‰ and flows about 77 meters below its start.

Blümelbach

The Blümelbach is the right upper reaches of the Rittersbach, which is even somewhat longer than the Rittersbach. It rises on the eastern edge of the hamlet of Hohenholz next to the K 2594 at about 371  m above sea level. NHN and flows almost northeast to the end. First it follows a dirt road to the B 19, crosses it and a little later enters its Waldklinge between Mittelbühl on the left and the Gewann Blumlenshalde on the right. At the end of this it turns in the corridor southwest of Tullau accompanied by a tree gallery to the northwest and flows about 150 meters further from the right and at about 310  m above sea level. NHN in the Rittersbach. The Blünelbach is about 1.7 km long and thus a little longer than the Rittersbach, which is only 1.4 km long to its mouth, it has an average bottom gradient of about 30 ‰ and flows about 51 meters below its origin. Its catchment area of ​​around 0.9 km² remains under the 1.1 km² of the Rittersbach upper reaches until the confluence.

Catchment area

The Rittersbach has a catchment area of ​​around 2.4 km², which , in terms of natural space , lies in the lower Haller Bay area with the rose garden of the Hohenlohe and Haller Plains . It is highest on the great plain in the west, where at the edge heights up to about 373  m above sea level. NHN can be reached.

It borders in turn in the north on that of the Geißklingenbach , near its mouth in the north-east then on that of its receiving water Luckenbach , which flows into the Kocher just below the Mühlkanal, which receives the Rittersbach . On the south-east side, in front of the northern edge of Uttenhofen, a small stream flows over a blade to the Kocher above. The remaining competitors are all left, successively higher tributaries of the beaver , which feeds the Kocher a long way above the Rittersbach , the Wolfringenbach in the south, the Ritterbach (!) In the southwest and the Kressenbach in the northwest.

The catchment area is divided into two distinctly separate parts, the plateau in the west and the much smaller abandoned Kocher loop around Tullau. On a slope this and the deep blade cuts the streams previously stehr forest, everywhere else is open agricultural landscape, which is used predominantly for agricultural purposes.

The settlement areas in the area are the Mündungsweiler Tullau belonging to the municipality of Rosengarten , which is mostly within, a few buildings of the predominantly outside hamlet of Raibach of the municipality in the north-west and the larger part of the hamlet of Hohenholz in the south-west, which belongs to the district of Bibersfeld of Schwäbisch Hall . With the exception of a small gusset in the Schwäbisch Hall-Bibersfeld district around Hohenholz, the catchment area belongs entirely to the Uttenhofen sub-district of the Rosengarten community.

Tributaries and lakes

Origin of the Rittersbach at about 363  m above sea level. NHN on the southern edge of the rose garden hamlet Raibach at a field path cross. The creek runs first westward around in the ditch next to the long meadow up to the B 19 and then digs after their passing under ENE without accompanying way into his forest sword .

  • Blümelbach , from the right and finally south-east to about 310  m above sea level. NHN shortly after the blade emerges on the upper meadows of the abandoned Tullauer Kocherschlinge, 1.7 km and approx. 0.9 km². Arises at about 371  m above sea level. NHN on the eastern edge of the Schwäbisch Hall hamlet Hohenholz and initially flows northeast for a long time.
    Up to this tributary, the Rittersbach itself is 1.4 km long and has an approx. 1.1 km² sub-catchment area.
  • Less than a hundred meters across from the Blümelbach estuary, a ditch that is quite water-rich from the start is created in the wet Upper Meadows towards the northeast, which flows along the Tullauer Steinbühl on its northwest side and, after Lauf, on the edge of a field on the left on the edge of Tullau's development, permanently in a doldrification disappears. According to the contour line, it should most likely end up following the Wirtsgasse into the twisted lowest Rittersbach, but it could also be led a little further down the Rittersbach into the Mühlkanal. In the first case, this brook is approx. 0.6 km long and has a catchment area of ​​approx. 0.2 km².

Mouth of the Rittersbach from the left and finally west-southwest to about 287  m above sea level. NHN in Rosengarten- Tullau opposite the confluence of Kirchgasse in Mühlstraße (K 2597) in the Mühlkanal to the left of the middle stove . The Rittersbach is 2.2 km long and has a catchment area of ​​around 2.4 km².

geology

The Rittersbach begins its initial trench course in a layer of loess sediment made of Quaternary deposits, which occupies the heights between the Bibers and the Kocher well beyond the catchment area. It soon reaches the Lettenkeuper ( Erfurt formation ) below, roughly at its intersection with the K 2504 from Hohenholz in the direction of the B 19 . This is where it begins to deepen, which is initially still slow, which only intensifies beyond the main road, whereupon it soon cut into one of the forested blades typical of the landscape in the Upper Muschelkalk . This layer also forms the step between the plateau in the west and the abandoned Kocher loop around Tullau, into which he crosses from the blade. In it it runs until the very end in alluvial land and passes the Steinbühl cusp , standing on the left, at most ten meters high , the shell limestone remnants of the former loop. In the lower part of its course there is loess-containing floating earth up close to the stream , as well as on the northern edge of the loop.

On the second upper course of Blümelbach, which flows early into the loop of the river in the Rittersbach, the same sequence of layers can be found along the course, its blade is slightly shorter.

River history

From an orographical and geological point of view, the most conspicuous in the catchment area is certainly the no more than ten meter high Steinbühl cusp , the circular mountain of the old Kocher loop roughly in the middle. On the mountain side of this is the saddle between the two creek troughs to the right and left of it at about 307  m above sea level. NHN , only about 20 meters above the mouth of the Rittersbach. The loop was only broken in geologically more recent times, which is also supported by the earlier mill with the Mühlkanal (today a factory) at the breakout point. Such places were popular mill locations because of the uneven gradient there.

On the stretch of water between Rosengarten- Westheim and Untermünkheim there are several old loops and high terraces of the Kocher, the one in Tullau being the largest.

A map from the first half of the 20th century does not show a continuous Rittersbach as it does today, rather the course ends there shortly after it emerges from its blade. A little further down, for example at the aforementioned point on the saddle, a source is drawn that feeds the following run. The end of the upper and the beginning of the lower run are closer than today's run to the origin of the trench on the left of the Steinbühl, which is missing there. It remains to be seen whether the left-hand trench was fed by the upper Rittersbach at that time (given that the Rittersbach was not so deeply deepened after the blade entered) or whether the map image there is unreliable.

Nature and protected areas

After the tree gallery begins a little earlier, the Rittersbach begins to deepen after the B 19 and to commute easily over a bed that is less than two meters wide. He piles up sand and gravel banks and sometimes the bank breaks off. A little later , when Rumel won his blade, the accompanying trees broadened on both sides up to the upper slope. At the exit into the old Kocherschlee the forest stops abruptly, but a gallery continues to accompany the stream that has apparently been straightened there and initially deepened into the alluvial land. In sections he walks in concrete bowls. From where he passes the Steinbühl on the left, a dirt road follows him, the stream is now less deepened and partly blocked with stones. On the outskirts of Tullau it goes into its Verdolung, in which it remains until its mouth.

The Blümelbach, which runs very close to nature there, but rather straight, is accompanied by a tree gallery in front of the main road. The flow may stop on this section. After the main road it begins to commute a bit and dig in more to a blade. After stepping out of the old Kocher loop and turning to the left, it is also quite straight, deepened and accompanied by a hedge.

The ditch that begins in front of the Steinbühl and runs past it on the left is created in a damp meadow, which apparently arises slightly above the Rittersbach running deep in its channel and so at least today it cannot be fed by it, but apparently from the slope of the river bend, It then runs until it drifts along the northwestern edge of the hamlet as a straight, almost bare ditch, hard along a field.

On both sides of the slopes of the Steinbühl Umlaufhück there are field hedges, on one side there are also lime stones from a very narrow field. So there is shell limestone in the subsurface of the hump, while the deeper terrain to the right and left of it is covered by alluvial land.

The two brook blades in the shell limestone and the slope down into the old Kocherschlinge belong to the nature reserve Kochertal between Westheim and Steinbach including Klingenbach as well as goat and donkey blades . The Mittelbühl between the two brook blades and partly also terrain on the other sides of the brook belong east of the main road to the landscape protection area Kochertal between Westheim and Steinbach with side blades and peripheral areas , and below the slopes of the Kocherschlinge then also a large part of this partly to the outskirts of Tullau.
