The Stiersbach is an approximately 3 km long stream in the area of ​​the municipality of Oberrot in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the lower Fichtenberger Rot from the left and northeast on the eastern edge of the village that gives the municipality its name . Its right upper course is the Erbsenbach .

geography

course

swell

The sources of the Stiersbach are located in the Mainhardt Forest northeast to east-northeast of Oberrot a little away from a high road section of the K 2611, which here in continuation of the northwestern direction of the Kirgelkamm runs from the Schwarzen Lache at the easternmost courtyard of Stiershof over the Suhlbühl-Kuppe to Frankenberg in a strip of land, later in a closed forest.

Upper course Erbsenbach

The peas Bach - with water code 2386474 - is the main strand headwaters and springs from the peas well little northeast of Hohenhardtsweiler hamlet in the forest at about 485  m above sea level. NHN and initially runs south for about half a kilometer under constant deepening until it unites with the Eisbach , which rises from the Klingenbrunnen near Hohenhardtsweiler and runs eastwards through its short blade. Then the Erbsenbach changes to the south-east course and takes two more large tributaries from the left and the above-mentioned Höhenstraße over a longer stretch, soon the Reuterklingenbach , finally the Kohlklingenbach . 1.4 km below its source, it then unites near the edge of the field with the left upper reaches of the Stiersbach .

Upper course Stiersbach

The Stiersbach - with water code 23864744 - rises higher to about 508  m above sea level. NHN between the easternmost and northernmost courtyards of the scattered settlement hamlet of Stiershof in a blade crack surrounded by an upper slope corridor and runs, accompanied by the gallery, to the west-south-west through the Hintergraureut forest . After a run of 1.1 km and without having absorbed a significant inflow except for a short right upper course from a blade beginning at the northern courtyard, it reaches 391  m above sea level. NHN the right pea creek.

Lower Stiersbach

The stream called Stiersbach from here on like its left upper course - with water code number 2386474 - now flows a total of 2.0 km to the south-west. On this path he soon leaves the forest, passes the Stiersbach residential area on the lower left slope, then a group of buildings on the right at the inlet of a short wooded hollow in the Gewann Schlat and then crosses under the Frankenberg – Oberrot road (K 2611), which is from the high road section mentioned here after a further south-western section and a valley climb around the residential area Stiersbach entered the valley floor. Opposite the hollow in the Schlat and further down near the road crossing, two small, temporary tributaries run to it from nearby hillside springs that once apparently fed ponds that have now silted up. Then it pulls straightened through its hollow, which opens more and more to the Rottal, under slopes covered by hedges and dry grass, initially accompanied by a narrow strip of forest on the embankment of the left foot of the slope. In a thin tree gallery it passes a newer settlement area Oberrot on the right slope behind another short creek inlet from this side, then crosses under the Rottalstraße L 1050 and finally flows next to a road bridge on the eastern outskirts of Oberrot opposite the larger part of a large wood processing company in their here quite wide floodplain from the left to about 352  m above sea level. NHN in the lower Fichtenberger Rot .

The brook has a length of 3.4 km on the main strand with the upper course Erbsenbach and a mean bed gradient of 40 ‰.

Catchment area

The Stiersbach drains a catchment area of 3.3 km² in the subspaces Rear mainhardt forest and - already at the lower reaches of the Red Valley - Gaildorfer pool of natural space Swabian-Franconian Forest . From an arch that connects the northernmost and easternmost point a little above the sources of its large source brooks, the Erbsenbach and Stiersbach , it extends about two and three quarters of a kilometer to the southeast to the mouth; across it it is about two kilometers wide at its widest point. Its narrow mouth wedge starts far below.

The north-eastern watershed of the stream catchment area also limits the extensive river system of the Fichtenberger Rot against that of the Kocher below the Rot inlet and is consistently at an altitude of 505  m above sea level. NN and above; it follows near the Höhenstraße section of the K 2611 from northeast Hohenhardtsweiler to Oberrot; the highest point in the middle of the section is the summit of Suhlbühl at 529.9  m above sea level. NN . The catchment area of ​​the Dendelbach , which flows into the lowest course of the Bibers tributary to the Kocher, lies on the outside on the outside until a little after this summit , then shorter to the eastern tip on the edge of the Schwarze Lache forest , where the terrain is at around 522  m above sea level. NN is that of the Mettelsbach , which also runs below the Rot itself to the Kocher. Here the watershed bends to the right and southwest and follows the slowly falling road up to a height of about 495  m above sea level. NN , behind this left watershed, the Diebach, which flows into the Rot at Fichtenberg itself, competes on the longer section in the form of its upper course Steinbach , only then does the border line quickly drop into the Rottal. The right watershed of the catchment area on its northwest side separates after the ascent from the wide Rottal from the drainage area of ​​the Altenbach , which flows over the Söllbach to the Rot above Oberrot and the Stiersbach estuary.

All streams are unpopulated. On the right watershed towards the Altenbach, the hamlet of Hohenhardtsweiler lies mainly on the Altenbach side, close to the upper and then the left the widely scattered courtyards of the hamlet of Stiershof; Scheuerhalde last on the left before the valley descent of the watershed is here just beyond. Above the south-west flowing middle course is the Stiersbach single courtyard near the bottom of the corridor, a little further down on the opposite side of the course there is an unnamed group of buildings. Near the mouth of the Rottal, some of Oberrot's houses are just in the catchment area.

NHN at the beginning of a wooded blade crack between the northern scattered settlement yards of Stiershof. This upper reaches of the name remains in length as the catchment area below the corresponding values ​​of the Erbsenbach of 1.4 km and approx. 1.1 km², the Stiersbach nevertheless continues from here on almost in the direction of its upper reaches to the southwest to the mouth.

Mouth of the Stiersbach from the left and northeast to about 352  m above sea level. NHN on the eastern edge of the village of Oberrot opposite the large sawmill and next to the red bridge on Eugen-Klenk-Strasse in the lower Fichtenberger Rot . The brook is 3.4 km on the main line with the right upper course, Erbsenbach, but on the secondary line with its name upper course, it is only 3.1 km long and has a catchment area of ​​3.3 km².

Fichtenberger Rot river system

geology

The brook and catchment area of ​​the Stiersbach are in the Mittelkeuper . The highest geological layer that occurs is the Stubensandstein ( Löwenstein Formation ), which lies in a fairly wide and almost uninterrupted strip on both sides of the northeastern watershed and whose border to the underlying Upper Bunte Mergeln ( Mainhardt Formation ) initially follows the watershed in the northwest. The south-western one, on the other hand, soon runs in a long and thin strip of this upper colored marl, then, as opposite, still on the plateau in the silica sandstone ( Hassberge formation ). In the further sequence of layers on the slopes above the Lower Bunter Marls ( Steigerwald Formation ) and the reed sandstone ( Stuttgart Formation ) down into the Gipskeuper ( Grabfeld Formation ), the reed sandstone appears only as a very narrow band. The gypsum keuper on the middle and lower slopes and in the valleys almost to the mouth covers most of the catchment area. The flat Rottalgrund is traversed by a wide floodplain sediment band, a narrow one also follows the two large upper reaches from their change into Gipskeuper.

The asymmetry of the stratification on the right and left watershed is probably explained by the fact that, for example, on the Eisbachklinge – Reutenklinge line, the outer peripheral fault on the south-south-east side of the Neckar-Jagst furrow runs through the catchment area, the deep floe of which is towards Hohenhardtsweiler; the tectonic lower elevation brings the geologically higher parallax sandstone layer to about the same height as the deeper layers on the left watershed.

The highest source of the Stierbach-Oberlaufzweig arises at the lower limit of the Stubensandstein, the Erbsenbachquelle geologically deeper in the Upper Bunter Mergeln or even the silica sandstone.

At two points down from the Stiersbach residential area, there are former marl pits in the valley.

Nature, landscape, protected areas

The catchment area of ​​the Stierbach lies entirely in the Swabian-Franconian Forest Nature Park , the greater part of the corridor on both sides of the creek after it emerges from the forest in the Fichtenberger Rot-, Murr- and Fornsbachtal landscape protection area with adjacent mountain ranges .

Its upper reaches, its forest and its corridor up to the first road crossing of the K 2611 are very close to nature. The upper course blades of the Stiersbach show the typical picture of the Keuperberge of the Swabian-Franconian Forest: watercourses rich in rubble, over which the steep slopes show a tendency to slide, especially in the marl sections. In some places the beds merge flat into the slopes, in others they are clearly deepened. On the forked spring blade of the name run there are bare rock walls, beneath which are boulders and fallen tree trunks. In the Reutenklinge you can find grotto-like undercrowded silica sandstone overhangs, from which the usually low water flow of the brook falls. Towards the end of its forest section, there are small sand and gravel banks in the one to two meter wide bed.

At the exit of the forest, where the brook meanders more strongly, there is a reed bed in an adjacent wetland. In the corridor section, there are several field hedges on the slope where there are several dry grass areas.

A little at the road crossing of the K 2611 begins the straightened lower section up to the mouth, which was planted with gray alders, which are now renewed by stick movements. On the left bank there are wet meadows in two places.
