The Ziegelbach is a nearly 2 km long, south to west running brook in the area of ​​the small town of Langenburg in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the middle Jagst in the village of Bächlingen from the right .

Surname

On the topographical map only the lower reaches of the Ziegelbach on the slope of the Jagsttal under the L 1036 are labeled with this name. The official river map suggests his left upper course under the same name. Since the Langenburg brickworks presumably gave the stream its name, but it is located close to the right and not the left upper course, according to local opinion the right upper course branch could have been or will be included in the Ziegelbach.

geography

course

The Ziegelbach-Unterlauf arises less than 100 meters east of the serpentine of the valley climbs of the L 1036 state road, which leads down from Langenburg to Bächlingen, in the lower edge of the forest in the upper Jagsttalwald. Here unite at about 366.4  m above sea level. NHN is the left upper course running westwards and the right upper course coming from the northeast, both of which flow down the valley for the last few hundred meters in one of the typical shell limestone blades .

Left upper course

The somewhat longer left upper course arises at about 470  m above sea level. NHN on a group of trees next to the L 1033 from the Gerabronner village of Michelbach an der Heide to Langenburg about half a kilometer before the Langenburg outskirts. Opposite the north side of the road is a well-developed dirt road, 200 meters to the northeast lies a medium-sized forest island above the source of the creek, which initially runs in a ditch between the field boundaries to the southwest. After just under 300 meters, the ditch turns to about 460  m above sea level. NHN to the west. About 100 meters east of this turn, a short stream sinks into a shrinkage, which runs westward in a natural hollow and whose bed is completely suspended after the shrinkage.

For the next almost 300 meters, the stream crosses under the road from Langenburg in the northwest to the Gerabronner hamlet of Binselberg in the southeast on the plateau above the Jagst and separates the Breber corridor on the left and Spitzäcker on the right. Then he steps on just 450  m above sea level. NHN enters its steep Waldklinge, where it flows under the newer development of a tourist hotel complex on the Sporn Roseneck on the right for the next half a kilometer to the valley.

The left upper course is about 1.0 km long and has a catchment area of ​​about 0.7 km².

Right upper course

The first section of the right upper course arises at about 475  m above sea level. NHN about a hundred meters east of the Langenburg outdoor pool, which it then runs towards along the border between a field and a meadow with little vegetation on the bank. This section ends at the Bad, the creek flows from there apparently underground about southwest towards the former brick hut, which is now used as a church parish hall, and there crosses the L 1033. Beyond, the section that is open again begins in a forest blade that borders the Roseneck spur on the left and is only about 300 meters long.

The right upper course is about 0.9 km long and drains just over 0.4 km².

Lower course

The lower course runs in a tree-lined railing channel between open terrain on both sides initially in the west direction of the left upper course and immediately crosses the path of the L 1036. Then it turns more and more to the south-west and flows under the lower path section on the left and the old path on right slope towards Bächlingen, the outskirts of which he reached about halfway along the way. Apart from driveways and road crossings, it also flows openly in the village. At about 291  m above sea level. NHN it flows a little above the river bridge from the right into the only 0.2 km long mill canal of the Mosesmühle of the village, which itself flows back just a stone's throw further down into the middle Jagst before the bridge .

The Ziegelbach is approx. 0.9 km long from the confluence of the two upper reaches and approx. 1.8 km from the origin of the left upper reaches. On this entire way from the source on the state road it loses about 179 meters in height, its mean bed gradient is about 98 ‰; the upper reaches are steeper again in their blade sections by half.

Catchment area

The Ziegelbach has a 1.5 km² catchment area, which in terms of natural space belongs to the Kocher-Jagst plains . The upper reaches and the Ziegelbach half way between the Jagsttalhangwald and the Bächlinger outskirts are in the lower area of Bartenstein-Langenburger Platten , the remainder of the lower reaches in the lower area of ​​the Middle Jagsttal .

The with about 489  m above sea level. NHN's highest point of the catchment area is at its northeastern tip near the Höhweg from the eastern edge of Langenburg to the forest island of Grund, which is beyond the catchment area borders . The eastern watershed from there to 482.6  m above sea level. The Ritterhöhe reaching NHN borders the catchment area of ​​the Michelbach , the last major tributary of the Brettach . Beyond the adjoining southern watershed from the Ritterhöhe to the estuary, the Jagst , which also includes the Brettach, experiences only an intermittent inflow from the Binselberger Klinge and from a few, even less constant, short slope channels further downstream. Behind the northwest side of the catchment area stands the Langenburger Bergsporn, from which no constant tributaries reach the Jagst on this side. Beyond the Bergsporn ridge in the north, the Schindbach flows westwards to the Jagst below its Langenburger valley loop.

There is only a little forest in the catchment area, it stands in the less than 500 meters long blades of the two upper courses and on the upper valley slope of the Jagsttal on the left and in a small gusset in the east, where part of the prehistoric Langenburger Viereckschanze lies on this side of the Scheide. To the left of the Ziegelbach on the Jagsttal slope lie meadows, everywhere else in the open corridor almost exclusively fields.

The eastern parts of the city of Langenburg to the outdoor swimming pool on the outskirts and to a tourist hotel complex (previously a holiday home area) in the south-east of the city center have been occupying part of the heights of the western catchment area since the second half of the 20th century, while previously only at the beginning of the Klinge the brickworks stood isolated on the right upper course. A large part of the estuary village of Bächlingen is also within. At the Ritterhöhe in the southeast corner of the catchment area, about 12 hectares of it belongs to the Michelbach an der Heide district of the small town of Gerabronn , the entire remainder to the small town of Langenburg .

Confluence of the two headwaters of the Ziegelbach at about 366.4  m above sea level. NHN less than 100 meters east of the serpentine serpentine crossing the blades of the L 1036 Langenburg - Bächlingen under the spur Roseneck between the two upper course blades . The brook flows in continuation of the left upper course initially west and then more and more southwest in a natural terrain channel between the lower section of the Landesstraßensteige left and the Alte Steige right.

  • Left upper course, approx. 1.0 km and approx. 0.7 km². Arises at about 470  m above sea level. NHN at a group of trees about half a kilometer before the entrance to Langenburg, left of the L 1033 Gerabronn - Michelbach an der Heide - Langenburg.
    The stream, which initially flows in a ditch between fields, initially runs southwest.
    • At about 460  m above sea level. NHN bends the Bachgraben, shortly before hitting the Binselberger crosses way about Western run; about 100 meters east of this point lies in a valley basin coming from the east in a field hedge at at most 465  m above sea level. NHN the sinkhole of a short, very short and unstable brook approaching the valley line, the bed of which then stops there.
  • Right upper course, approx. 0.9 km and over 0.4 km². Arises at almost 475  m above sea level. NHN about a hundred meters east of the Langenburg open-air swimming pool, to which it runs, and then bends in its area, which is now underground, to about a south-westerly run. Open run again only after crossing under the L 1033 near the Ziegelhütte in its lower course.

Mouth of the Ziegelbach from the left and finally northeast to about 291  m above sea level. NHN from the right and finally northeast to about 291  m above sea level. NHN a few meters before its mouth at the river bridge of the L 1036 Langenburg - Braunsbach in Langenburg - Bächlingen in the mill canal of the Moses mill next to the middle Jagst . The Ziegelbach is approx. 0.9 km long from the confluence of the two upper reaches, approx. 1.8 km from the origin of the left upper reaches and has a 1.5 km² catchment area.

geology

The two upper courses arise on the plateau to the right of the Jagst in the Lettenkeuper ( Erfurt formation ), which covers a large part of the region . In the troughs of the two strands, which were initially only slightly deepened, there was a small alluvial band almost from the beginning. The Upper Muschelkalk below begins at the beginning of the two forest blades and ends roughly at the confluence of the upper courses. In the area of ​​the Middle Muschelkalks below, the brook almost reaches the local boundary of Bächlingen. From there to the confluence on the left on the lower slope Unterer Muschelkalk and on the right on the flatter opposing slope and in the village of Bächlingen, terrace sediments of the Jagst, which probably formerly extended further east, lie. Some short faults are suspected in the subsurface, running approximately north-south and perpendicular to it, the latter including approximately on the valley axis of the lower left upper course and upper lower course.

The sinkhole mentioned for the tributaries a little east of the kink of the right upper course, in which a small stream sometimes disappears, shows karst formation of the Upper Muschelkalk, which begins only a few meters below the surface. This relative position in the strata profile is typical for the sinkholes in the region.

Nature and protected areas

From the beginning of the two razor branches, the Ziegelbach and its upper reaches are steep and sometimes raging brooks that fall over numerous steps and whose water flow fluctuates greatly. Your bed is about 2–6 meters wide and there is a lot of rubble on the rocky bottom in places. After the floods in 2016, the blade slopes showed landslides with bare, bare earth in some places. The mixed forest on the slopes consists mainly of ash, sycamore maple, hornbeam and red beech, spruce are rarer. The blade of the eastern upper course shows remains of bank construction and crossbars made of stone blocks, which either fell into disrepair before the storm or were destroyed by it.

Below the Landesstraßensteige a strip of wood accompanies the brook, which now runs outside the forest to the outskirts of Bächlinger, like a trench in a railing channel, which is bordered by barriers.

The two upper courses in their lower blade sections already flow in the landscape protection area Mittleres Jagsttal with side valleys and adjacent areas , as does the lower course afterwards to the local border of Bächlingen, which re-enters it the last meters before the Mühlkanal.

Heavy rain in 2016 and protective measures

On May 29, 2016, heavy rain fell in the region, which also attracted a lot of national attention due to the pictures of the devastation from similar Klingenbach brooks to the Kocher in Braunsbach , about 7 km southwest of Bächlingen . In Bächlingen, the Ziegelbach threw rubble between the houses, and the flooded masses of water washed a small car into the creek bed. The first protective measures were taken in June 2016 at a cost of 120,000 euros. In the meantime, the wall of a scree retention basin stands a little in front of the village across the incision of the creek, further upwards near the Ziegelbach crossing of the L 1036 another protective wall for scree trapping is currently (Easter 2019) before completion. The protective measures are designed for a hundred- year flood, with an additional "climate surcharge" of 15–20%. From the foundation up to the trapezoidal overflow recess, this barrier is about a man's height or slightly above it, has a narrow central slot for the normal drain and is around 10 meters wide.

Langenburg has spent a total of 1.1 million euros on flood protection, 83% of which came from state grants. The Jagst crosses the area of ​​the small town over a length of 9 km with its deeply cut shell limestone valley, which is joined by other steep side cliffs here.
