The Furtbach is a creek almost one and a half kilometers long in the area of ​​the municipality of Bühlertann in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the middle Bühler from the left and west at the last dirt road bridge before the village of Bühlertann .

Surname

According to two locals, the name of the stream is Furtbach . In the water database of the responsible state office it is listed as Keimenkling e bach , presumably this is a new formation after the (written) valley name Keimenklinge recorded on maps , according to which the written form for the brook name would then normally have to be Keimenkling en bach . This formation inconsistently transcribes the unstressed final wording syllable en , which is only realized as Schwa in the local dialect , which occurs here in the designation as en at the front and as e at the end with the same pronunciation .

geography

course

The Furtbach begins its course at about 401  m above sea level. NHN in the rearmost seed blade in the vicinity of three small forest islands on the slope of the valley end. Overall, it runs eastwards in an arc that swings slightly to the left. From a single tree in a damp meadow at the top, a trench channel in the middle of an overgrown meadow wedge runs eastwards to the first pond in the valley. After about 50 meters, a second, wider herbaceous wedge of this type joins it , coming from a tip of the forest of the Kohlhölzles in the southwest . Its rivulet apparently leads the greater part of the pond inflow from a waterlogged first terrain platform on the rise to the Leippersberg (up to 447.6  m above sea level ) in the south. More recent aerial photos (as of summer 2017) show this dining area terrace at a little below 420  m above sea level. NHN about 300 meters further south three fresh ponds with even just lying crumb on the banks, which until about 2005 sure did not exist. The water from both spring branches at a fish hut flows into the upper, a little over 0.2 ha large and elongated fish pond via a connecting small pre-pond.

A hundred meters further on, this drains via a second short dole into the lower fish pond, about 0.2 hectares in size. The Furtbach leaves this in an approximately east-northeast run for a long time. Right after this pond he inflow along an unpaved dirt road from a small wood blade , the close attaches to the right terrain level at the east end of the above waterlogged area, but they are not dehydrated usually superficial, because then put the bed in the blade and this itself towards the top.

The Furtbach now flows in a wide and deep meadow hollow. This is bordered between the eastern Hohenberg mountain spur in the north, under whose narrow plateau (fairly constant approx. 423  m above sea level ) up to half a dozen field hedges, some of which are long, run along rain areas of meadow terraces lying one below the other, and the Leippersberg in the south Forest partly reaches down to the lower edge of the slope and its spur foothills Sennenberg (up to 424  m above sea level ) accompanies the run longer on this side. The stream, which is hardly ever overgrown by trees or bushes, passes twice a shed with an adjacent storage area on its way towards the end of its valley. From the first, from the now quite flat left slope in front of the Spornspitze of the Hohenberg, fields reach down to the shore. On the second of Bach passes under, while to the right kinking, Bühler valley road L 1072 Kottspiel -Bühlertann and then accompanied on his last quarter kilometers a dead straight asphalt field southeastward until the last river bridge before Bühlertann. In the first half of this section, after 2000, there was still a gapless row of poplar trees, all of which have since been cut. At the bridge, the Furtbach then flows to about 373  m above sea level. NHN from the left into the middle Bühler, which flows very slowly here .

The Furtbachlauf ends after its 1.4 km long run from its origin in the upper Keimenklinge about 28 meters lower at the Bühler; its mean bottom slope is therefore around 20 ‰.

On an older official map from 1936, the Furtbach is still uneven and more irregular after the bridge on Bühlertalstrasse in the Bühleraue, but the confluence with the Bühler, which was much more winding at the time, was roughly at the same point as it is today. The dirt road with the associated river bridge and the avenue that has since disappeared did not exist back then.

Catchment area

The Furtbach drains an approximately 1.0 km² area eastwards to the central Bühler , which in natural terms belongs to the Hohenloher and Haller plains with the upper and western parts in the lower area of Fischachbucht and edge heights of the Swabian-Franconian forest mountains , with the eastern and lower parts of the Vellberger Bay .

The vast majority of the catchment area lies in the Gipskeuper ( Grabfeld Formation ), the step-forming Corbula layer in the shape of the narrow Hohenberg spur (up to a little over 423.4  m above sea level ) on the left and the first level to the Leippersberg on the right . Towards the Leippersberg in the south lie the estheria layers of the Gipskeuper on the second ascent and at the top the reed sandstone cap ( Stuttgart formation ) of the 447.6  m above sea level at the summit . NHN high Leippersberg , the highest point in the catchment area. On the rear Sennenberg there is a wooded small round hill (up to a little over 424  m above sea level ) with a reed sandstone island. Recently while crossing the wide Bühleraue the creek running after these tertiary layers in which only in the Quaternary seasoned flood sediment strip of the river.

The northern watershed on the narrow Hohenberg borders the catchment area of ​​the next Bühler tributary Seegraben in Bühlertann, which is similar in size to the Furtbach. Behind a wider plateau in the west, the terrain slopes down to the large upward Bühler tributary Fischach , which in this area only absorbs insignificant channels from the sheath. Also behind the Leippersbergs summit, over which the, like the western, also only short southern border of the catchment area runs. The again longer south-eastern watershed runs over the right Sennenberg spur to the mouth, behind it two unstable channels from small valley blades drain to the Bühler between Fischach and the Furtbach itself.

On the slopes of the Leippersberg there is predominantly forest, on its cap there are fields in a clearing, as well as on the plateau in the west and to the left of the course in the flatter slope in front of the Hohenberg-Sporn. In the valley floor and on the steep ascent to the Hohenberg, which is stepped up through a few long bushes, there are almost only meadows.

There is no settlement anywhere, but the hamlet of Leippersberg stood exactly on the southern watershed for half a millennium , which in 1852 still had 21 inhabitants and completely disappeared in the 20th century without any recognizable building remains.

The Mittelfischach suburb of the Obersontheim municipality has a very small share of the total area on the western plateau . The vast areas of the Leippersberg above the first elevation level mainly belong to the Geifertshofener suburb of Bühlerzell . However, the vast majority of the area covered by the three municipalities is in Bühlertann , in whose area the entire stream is located.

At that time, next to an unpaved field path, close to the edge of the terrain step down to the Keimenklinge, in whose deep channels the water stood even in midsummer, there was an area rich in pools with scattered tree roots that were gray in the sun. The dry, steeper slope above was partly only covered by low brambles.
