The Bröckinger Bach is a creek almost three kilometers long in the Unterrot district of the small town of Gaildorf in the Schwäbisch Hall district in north-eastern Baden-Württemberg . It flows into the middle Kocher from the right opposite the northern edge of the Unterroter settlement Arwatal .

Despite its name, the stream does not run through the Gaildorf-Unterrot hamlet of Bröckingen , but flows beyond a ridge that juts out north of Bröckingen to near the Kocher in the west, on which the Kieselberg residential area stands.

geography

course

The Bröckinger Bach arises on the upper northwest slope of the wooded ridge of the Limpurger Mountains called Kieselberg , which stretches south-southeast between the Eisbach valley in the east and the Kocher valley in the west. There are at least two, at the top only periodically water-bearing spring streams. The source of the somewhat longer one rises at about 475  m above sea level. NHN approx. 150 meters north-northeast of the Schönen Wappenstein , a historical boundary stone on the hiking trail from Sulzbach-Laufen to Gaildorf, marked with a red cross . The young brook runs in a furrow in the terrain, initially northwest, after a hundred meters crosses a forest path at the upper bend in the slope and then digs a deep and steeply sloping blade between the Konradsreute on the left and the Ho (c) hwälzle on the right, in which it takes a good hundred meters to just a little below 430  m above sea level. NHN the even more unstable right source stream runs towards it.

The blade and the brook swivel to the west, about half a kilometer after the source mentioned, it flows through at a little over 400  m above sea level. NHN a pond dammed behind a forest path and then runs along the edge of the forest between the Hinteren Reute on the left slope and a less steep pasture slope on the right. From the north-east towards the Ladstatt, another small stream runs to the valley, at the end accompanied by a field path at the end of a valley trail down the Ladstatt. At below 380  m above sea level NHN , this side stream, about half a kilometer long, flows into a fork in the field. Initially very close to the westward path, the stream continues with small changes of direction under a gallery of trees. For the last time, the forest reaches down from the left slope to the creek bank, then it leaves it completely behind at a tiny pond on the wooden meadows .

While the mountain spur that accompanies the course a little further away on the left sinks ever deeper, the tree and shrub gallery along the stream, which continues with small changes in direction for a good kilometer to the west-southwest through an open meadow landscape, now and then repeatedly breaks. It crosses the federal highway 19 on its section between Bröckingen and Münster , on the other side in the very flat floodplain, the stream, which has always been less than two meters wide, soon flows into an altar stump of the Kocher , from which it finally flows to about 362  m above sea level. NHN from the right and finally northeast opposite the northern edge of the Unterroter settlement Arwatal flows into the middle Kocher.

The Bröckinger Bach is 2.9 km long from the source mentioned and falls on this route by about 113 meters, its mean bottom slope is about 40 ‰. It flows in its upper reaches partly under rocks, partly under clay slopes, from the edge of the corridor then mostly deepened in small meanders and over a sandy-gravelly, at most one and a half meter wide bed. In the lazy old arm, in front of which it deposited a small sediment island, the course then widens to around ten meters wide. Until the 19th century, the estuary was a little further down the kocher.

Catchment area

The Bröckinger Bach drains an area of ​​1.8 km², the higher parts of which in the east and south-east naturally belong to the Limpurger Berge sub-area , the deeper parts in the west to the Gaildorf Basin sub-area of the Swabian-Franconian Forest Mountains .

The inconsistent headwaters in the east are still in the silica sandstone ( Hassberge Formation ) of the plateaus of the Kieselberg or Ladstatt or in the transition area to the lower colored marls ( Steigerwald Formation ) below , into which the upper courses have cut steep blades. The gypsum keuper ( Grabfeld formation ) begins around the edge of the forest at the foot of the slope , in which the stream remains in a wide flood sediment band around the Kocher up to its mouth. Apart from these Quaternary deposits, there are layers of the Middle Keuper in the entire catchment area . Only somewhat downwards in the Kocher sets for the first time to the sub keuper computing Lettenkeuper ( Erfurt Formation a).

The highest watershed runs on the wooded ridge of Kieselberg and Ladstatt in the east, where at the southeast and northeast corner heights of just over 490  m above sea level. NHN can be reached. Behind this divide the Eisbach flows southeast to the higher Kocher. The upper catchment area is bordered by two western spurs of the Limpurger Mountains, over which the watershed to the next, partly less than 200 meters away, Kocher tributary Argersbach runs west to the river, on most of the route here in the lowlands. The spur in the south, also called Kieselberg , stretches for a longer time at a great height and only drops down to the river valley at the Gaildorf mineral swimming pool . Behind him, a stream that is emerging east of the hamlet of Bröckingen in the rafter blade and also runs westwards leads the drain to the Kocher above.

The banks of the Bröckinger Bach are free of settlements. Only the Kieselberg residential area on the spur of the same name drains to it , which, like the entire catchment area, is in the Unterrot district of the city of Gaildorf . Forests cover the mountain parts of the area in the east and south, with the exception of the flat plateau of the Kieselberg spur accompanying the left , where there are fields around the Kieselberg residential area. In front of the foot of the mountain there are initially only pastures and meadows, later more and more fields mix into the surrounding fields, which, however, avoid the run.

The inconsistent springs of the Bröckinger Bach are at around 475  m above sea level. NHN in small blades on the northwest slope of the wooded mountain ridge Kieselberg ( 490.4  m above sea level ), still above a forest path at the bend in the slope; The source of the main branch, which is hardly longer and has a richer catchment area, is located about 150 meters north-northeast of the beautiful Wappenstein on the Sulzbach-Laufen - Gaildorf hiking trail . With slight fluctuations, the stream flows roughly west and swings a little to the right.

The Bröckinger Bach is 2.9 km long and has a catchment area of ​​around 1.8 km².
