The Eltershofer Bach is a little less than a kilometer long brook in the district of Gelbingen in the city of Schwäbisch Hall in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the middle Kocher in the village of Gelbingen from the right and approximately east-northeast .

geography

course

The Eltershofer Bach arises on the edge of the Gelbingen district marking at the beginning of one of the shell limestone typical for the region sounding a little to the west and below the town of Breitenstein, which is just in the Eltershofen district , at around 350  m above sea level. NHN . The start of the run is in the forest in the head arch of the Alte Steige , which leads down from the K 2573 near Breitenstein to Gelbingen and is no longer used as a road , from which a hiking trail leads along the upper Kochertal slope towards the Schwäbisch Hall city center, and a good 10 meters below the next houses from Breitenstein. There is a spring version nearby.

The brook runs southwest through the Klingenwald and then continues in a narrow forest wedge that protrudes into the Gelbingen settlement area. After about half of its run, it then enters a hollow between Blumenweg and Hofsteige and at its intersection with Bergstrasse, after about half of the run, in which it crosses the rest of the Gelbingen. It flows a little north of the confluence of the Hofsteige in the B q9 under the federal road mentioned in Untermünkheimer Straße and then roughly follows the route of the streets Im See - Wiesentalstraße. A few meters down the bridge of Wiesentalstrasse over the river and a little before its arch in Gelbingen it then flows from the right to about 267  m above sea level. NHN in the middle cooker .

The Eltershofener Bach flows after a 0.8 km long run with a mean bottom gradient of about 99 ‰, about 83 meters in altitude below its start.

Catchment area

The catchment area of ​​the Eltershofener Bach is about 1.3 km². In the natural area of the Hohenlohe and Haller Plains, it is predominantly in an arc from north to northeast to east at the level of the Haller Ebene sub-area , while the blade in the west with the entire course belongs to the Haller Bay sub-area with rose garden . The greatest heights are about 404  m above sea level. NHN in the Bürgäckern a little west of Eltershofen on the northern edge and with about 409  m above sea level. NHN south-east of Breitenstein in the Gachtäckern near the Haller northeast bypass (K 2673).

Compete in turn

  • in the north an unstable Klingenbach from the Tannenberg , which flows to the Kocher below the valley loop, which stretches far to the west, below Gelbingen :
  • in the east the Diebach , an even deeper and more important tributary of the Kocher;
  • in the south the next upper right secondary blade of the cooker reaches the river at the nurses cemetery near the Gottlob-Weiser-Haus of the Diakonie-Klinikum , there is only very unsteady flow.

On the plateau, which is dominant in terms of surface area, there are almost only fields in the corridor, from where it slopes more steeply to the edge of the brook and down to the nearby edge of the forest, also meadows and orchards. On the very steep slopes below, which make up less than 10% of the total area, there is forest. The only places in the catchment area are the estuary village of Gelbingen in the district of the same name, which was built in the right Kocheraue and on the alluvial cone of the Eltershofer Bach, but today also continues up the slope opposite the northeastern Gelbingen Kocherbogen, which was only founded in the 20th century Place Breitenstein in the Eltershofen district directly above the beginning of the Klingen, both to the town of Schwäbisch Hall , to which the entire catchment area belongs, the western part of it to Gelbingen, the eastern part to Eltershofen, a smaller part in the south to Weckrieden .

Tributaries

The Eltershofer Bach has only a slightly more significant tributary in its blade, apart from small slope channels. Between the Gewannen Mähderwasen in the east and Steinhaus in the west, a forest blade emerges on the plateau a little over half a kilometer north-west of Breitenstein, which crosses the K 2573 on the middle slope and continues to wedge into the outline of Gelbingen's settlement, accompanied by trees. It only carries water periodically, this only flows into an underground hollow near house no.14 on Untermünkheimer Straße (B 19), which - after the hollow in the area that continues the blade in Gelbingen - in the area of ​​Wiesentalstraße into that of Eltershof brook must open, so very close to its own mouth. This only temporary stream is up to 0.5 km long and drains around 0.3 km².

Tube ride

On the northeast edge of Breitenstein in the Gewann Masselter , in Breitenstein and at the very beginning in the edge of the Eltershofer Bach there are some water catchments. In earlier times, the route of today's hiking trail from the beginning of the Klingen towards Hall's city center used to be a pipe journey , the drinking water from the springs at the Breitenstein residential area, which was only built in the second half of the 20th century, was mostly gently sloping south-south-west along the Kocherhang and above today's deaconess -Hospital headed over to town. In later times the water was evidently led in a stone channel, because you can still find isolated building stones with the characteristic semi-cylindrical hollow groove along the way. On the path, which shortens small sloping gutters in partly rather dilapidated viaducts, lies a number of shafts covered with sandstone slabs. Already near Hall's old town, neom the upper Nikolai cemetery, the line crossed the Wettbach on a viaduct in a very low location . This bridge, which is now used by the hiking trail, was restored towards the end of the 20th century; the characteristic semi-cylindrical channel also runs along its center line.

geology

The highest Mesozoic layer in the catchment area is the Lettenkeuper ( Erfurt Formation ) of the Unterkeuper , which still covers the shell limestone in the subsoil on the Haller level above the Kocher valley cut . in the highest elevations north and east of Breitenstein, it is overlaid by Quaternary loess sediment . At least today, the after itself only arises in its blade in the Upper Muschelkalk , which reaches down to the village of Gelbingen, where some Middle Muschelkalk then spreads out on the lower slope . However, since the stream has deposited a rubble fan near its mouth, it is often covered. The old Gelbingen, like many places in the middle valley of the river, was built on the rubble cone of a razor tributary, quite safe from flooding of the Kocher.

The blade follows a short fault line running from northeast to southwest.

Nature and protected areas

The Eltershofen brook and its only significant tributary only carry water at times in their blades. The Eltershofener Bach is about two meters wide in its own and built across the upper course with gabions , otherwise more natural, its bed is rocky and covered by rubble. The path down between Breitenstein and Gelbingen is dug into the slope, next to it, up to two meters high, mussel beam banks are visible.

The bed of its only significant tributary is usually less than a meter wide, and in its narrower blade there are sections of low rock walls next to the stream.

The blades and the steep slopes in the northeast on the part of the Gelbinger Kocherschlinge that drains towards the brook down to the edge of the village of Gelbingen belong to the Kochertal landscape protection area between Schwäbisch Hall and Weilersbach with side valleys .
