The Stettbach is a nearly 5 km long brook in the municipality of Frankenhardt in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the middle Speltach from the left and south-west just above the hamlet of Unterspeltach .

geography

course

The Stettbach arises at the eastern foot of the highest elevation in its catchment area, namely under the small plateau of the Mörder mountain in a shallow valley next to the lower forest path from Birkhof to Landesstraße 1066 . It rises at about 474 m above sea level. NHN and runs approximately east-northeast for the first half of its course. It already reaches the edge of the forest after about 200 meters, from which it then detaches itself after another distance. In a still shallow basin, it runs about 150 meters south of the state road to the K 2637, which branches off from this at the Gründelhardter Schützenhaus and leads south to Vorderuhlberg. In a more deeply deepened trough, it flows after the county road towards the hamlet of Hellmannshofen , which it then crosses. At the end of the village he passes an old chapel next to the road bridge of the L 1068 that has been built over him, which also branches off the state road at the Schützenhaus and leads through Hellmannshofen to Honhardt . As before, there is only sparse tree or shrub growth below the village on the banks, which are initially mostly lined with fields.

A quarter of a kilometer northwest of the Reishof flows into the first tributary Brechbach from the southwest, which rises in the local area of Vorderuhlberg over a slope and runs down in a corridor. About 0.4 km after this, the Ghaiwasenbach joins the Stettbach from the east. After this it flows further in a narrower valley in a north to north-westerly direction, initially briefly at the foot of a wood on the now much steeper right slope and from now on accompanied by an almost uninterrupted tree gallery. From the left and west-south-west, the Niederbach reinforces the water, which with its two upper reaches drains more than half of the Stettbach catchment area, together with its right upper course Madenbach is also its longest tributary. The left upper course of the Brunnenbach of the Niederbach runs through the largest village of Gründelhardt in the catchment area. From now on the meadows completely replace the fields on the banks.

A little below the Stettbach passes the Stettmühle on the left bank and soon afterwards it passes through the hamlet of Stetten itself, which is largely also on the left; At the end of the village, the K 2641 crosses it from Gründelhardt to Unterspeltach. The valley has become more tired and flatter again and is now slowly expanding. The brook passes the Eulenhof, which is a little further away from a wood on the left, and then enters the wide Speltachaue. About 0.3 km below the river bridge of the Sträßchen from Stetten in the direction of Crailsheim, the Stettbach finally empties at about 416 m above sea level. NHN from the right and southwest into the middle Speltach.

The Stettbach is the largest tributary of the Speltach both in terms of its length of 4.9 km and the extent of its sub-catchment area. On its course it has an average bottom slope of about 12 ‰.

Catchment area

The Stettbach drains an area of 8.4 km², the vast majority of which is part of the sub-area Burgberg-Vorhöhen and Speltachbucht of the natural area of the Swabian-Franconian Forest Mountains . Only a narrow marginal strip in the southeast around Vorderuhlbach is part of the adjacent sub-area Ellwanger Berge . The predominant deeper parts of it are attributed to the Speltachgrund , which includes more than just the often quite wide floodplain of the Speltach itself.

Beyond the entire south-western watershed, the catchment area borders on the roughly opposite Nesselbach , which, like the Stettbach, does not drain over the Speltach to the Jagst , but over the Bühler to the middle Kocher ; in its course , the one at 515.1 m above sea level lies on the killer . NHN highest point that drains to the Stettbach. Behind the entire northern watershed, which is 502.5 m above sea level. NHN reaches the highest point on the summit of the Nonnenkappel a little northwest of Gründelhardt, competes with the Bühlbach, Taubbach and finally Betzenbach , which flows into the Speltach a little above the Stettbach.

Beyond the eastern catchment area border near the mouth, only the little Schmindbach flows through Unterspeltach to Speltach. In the southeast, the upper reaches of the Honhardter Bach of the Jagst tributary Steinbach drains the outlying area. The watershed section against him begins in the forest at about 503 m above sea level. NHN , then follows the route of the L 1068 from Honhardt to Hellmannshofen for a long time , where it is hardly noticeable in the terrain, then it rises again steeply to the terrain step to the Ellwanger Mountains to a height of over 510 m above sea level. NHN near Vorderuhlberg. In less than half a kilometer of the catchment area in the very south, the catchment area meets that of the Blind Rot , which is the most important of the competing waters outside and flows into the upper Kocher. This is followed by the already mentioned catchment area of the Nesselbach, which competes here over its large left upper reaches Schenkenbach.

Apart from the highest areas and the steep slopes below, on which there is mostly forest, the area is an open, agriculturally used meadow landscape, the middle layers of which are mostly plowed, while the meadows dominate the meadows. The Stettbach, otherwise mostly straightened like its tributaries in the flatter area, shows near-natural meanders on the course for only one kilometer between the Stettmühle and the edge of the Speltachaue .

Localities

The entire catchment area is in the area of the community of Frankenhardt in the district of Schwäbisch Hall .

The Stettbach itself flows through the hamlet of Hellmannshofen , which is predominantly on the left, on the upper course ; on the lower course, the brook passes the Stettmühle on the left bank in quick succession and then crosses the hamlet of Stetten, which is mostly on the same side. The individual property Eulenhof, which is a little further to the left of the course, is a little further from the water.

The hamlet of Vorderuhlberg lies a little above the slope spring of the Brechbach inflow, to which it drains, and which on its lower course passes the Kleinweiler Reishof, which is slightly above the basin on the right. The hamlet of Altenfelden lies on the banks of the Ghaiwasenbach. The hamlet of Brunzenberg is located near the source of the Niederbach main upper course Madenbach, while the largest place in the catchment area, the village of Gründelhardt, is predominantly on the left on the slope of the Brunnenbach valley up to the Nonnenkappel, but with a small newer part of the settlement is also outside the Stettbach catchment area and drained to the Betzenbach. The hamlet of Birkhof, also known as Birklein, stands in the southwest close to the watershed to the Schenkenbach, which drains over the Nesselbach to the Bühler.

geology

The catchment area of the Stettbach, located in the Keuperbergland zone of the south-west German stepland , has a share in the south of the Ellwang Mountains , in which plateaus in the silica sandstone ( Hassberge Formation ) dominate, but lies with its predominant share in the so-called Speltachgrund in the clearing area of the one at the mouth in Gipskeuper ( Grabfeld Formation ) flowing Speltach outgoing erosion.

To the north of the edge of the step, for example on the Vorderuhlberg – Mainkling line, for tectonic reasons, some pebble-sandstone witness mountains have formed in the western ( Murderer , Gemeindewasen bei Gründelhardter Schützenhaus, plateau around Brunzenberg), northern ( Nonnenkappel bei Gründelhardt) and eastern ( Forst east of Stetten) The watershed is preserved, which is explained by the reversal of relief in the area of the Neckar-Jagst-Furche subsidence zone , which runs through the northern catchment area and extends far-reaching from the west-southwest to east-northeast , from which some brief transverse faults move into the interior of the catchment area.

The highest springs in the catchment area (Brechbach near Vorderuhlberg, Madenbach near Brunzenberg) arise near the layer boundary of the silica sandstone to the lower colored marls ( Steigerwald formation ), which broadly surround the hilltops on the slopes. The Stettbach itself arises a little deeper in the area of a small loess derivative island, the source rock of which was Quaternary deposited in the lee at the eastern foot of the Murderer . In terms of area, the reed sandstone ( Stuttgart Formation ) under the colorful marls is the dominant formation, especially in the western catchment area. In the floodplain of the Brechbach-Unterlaufs and along the Stettbach-Mittelllauf from its inflow to the bend at the inflow of the Ghaiwasenbach stream below in the Gipskeuper, especially on the right-hand side, its layers of Estheria and the Corbula-Bank are flat out. The lower Stettbach crosses a small tectonic ditch bordered by two suspected west-northwest-east-southeast running faults from below the Niederbach inflow to near the edge of the Speltachauen, where it now flows again in the reed sandstone. After the change back into the Gipskeuper, the estuary lies in the wide floodplain sediment band of the Speltach.

Geotopes in the reed sandstone are two ravines near Hellmannshofen, a ravine on the northern edge of Stetten and an abandoned quarry east of the hamlet on the ascent to the forest . Another geotope at the northern end of Altenfelden opens up the layers of estheria of the uppermost gypsum keuper.
