The Buchbach is a little more than four kilometers long, fine material rich, carbonate low mountain range in the district of Schwäbisch Hall in north-eastern Baden-Württemberg . It flows a total of approximately eastwards and almost entirely in the area of the municipality of Frankenhardt and unites on the southern edge of the village of Oberspeltach of the municipality with its left, approximately equal upper course Lanzenbach to Speltach .
Surname
On the official waterway map, the left of the two upper reaches of the two upper reaches, which begins on the Kohlsteige, is calculated as the creek on the lower reaches of the Buchbach . However, the official topographic map labeled in contradiction to the catchment richer right upper reaches, on the waters and map here as a soul Bach called - the name probably comes from the dialectal diminutive soul of the word lake - as Buchenbach . Since no remains of a lake dam can be seen anywhere on the Seelesbach-Lauf or a relevant name is given, but the Buchbachlauf crosses a Gewann Schwarzsee and also passes two small ponds near the mouth, the names could also have been mixed up. We are sticking with the naming of the official waterway map.
geography
course
The Buchbach arises on the wooded northeast slope of the Hackenberg called Kohlsteige in the lower slope area at about 473 m above sea level. NHN . It runs from its source about 0.7 km northwest of the Frankenhardt hamlet of Steinehaig from about eastwards and is initially a border stream between the town of Vellberg in the south and Frankenhardt in the north. After less than 150 meters, it passes under the K 2665 district road from Vellberg- Kleinaltdorf to Steinehaig in a hollow that is only a few meters deep . There it changes over entirely to the Frankenhardt area, where it now remains up to the mouth. It runs a little further through the Karrenhalde forest and then north of Steinehaig for almost half a kilometer through the Schwarzsee Flurgewann . before it separates the Klinge tub in the south and Greut and See in the north in a final ledge through the forest . From now on, permanently in the open corridor, it runs in a shallow meadow hollow up to 100 meters in front of the few houses at the lower foot of the slope of Waldbuch and kinks in the area of two small ponds on the right bank to the northeast.
Between the houses mentioned and the Bonolzhof in the north, which stands on a flat bump in the terrain, at the edge of the road that connects the two, the Seelesbach, a little over two kilometers long, flows from the southeast towards him. Less than 400 meters further down the valley in its now continuously widening meadow hollow, it is reinforced by the Seebach , which is also around two kilometers long and arises in the west-northwest in the forest. Afterwards, the Buchbach swings in a few, flat curves on its last almost two kilometers eastward run through a wide grassland floodplain. 400 meters before its end, opposite the Frankenhardt village of Overspeltach, which already occupies the left bank, the Birkbach, which is just over a kilometer long, joins it from the southwest . Along the southern edge of the village, it crosses the K 2665 Waldbuch – Oberspeltach and joins immediately afterwards at around 422 m above sea level. NHN with the left upper course Lanzenbach to Speltach coming from the northwest, which reaches the Jagst in a further seven kilometers long east course .
The approximately 4.3 km long Buchbach run flows about 51 meters below its source and has an average bed gradient of about 12 ‰.
Catchment area
The Buchbach has a catchment area of 6.7 km², which in terms of natural space lies entirely in the lower area of the Burgberg Vorhöhen and Speltach Bay of the Swabian-Franconian Forest Mountains . Its highest point is the flat summit of the Hackenberg at 511.2 m above sea level. NHN , to which a western corner of the catchment area runs out less than 400 meters southwest of the source of the stream.
On the left and north side it meets the catchment area of the left Speltach upper reaches Lanzenbach . Behind the right and south-eastern part of the longest part of the next large right tributary Betzenbach leads to the Speltach, the drain on the other side of this. In the far south-west, on the plateau around the Geschäufelte Marsh, the catchment area borders on the short Hahnenbach , which donates its water to the Bühler tributary over the Nesselbach . The prominent and hydrologically most important watershed in the west borders the catchment area of the Bühler receiving water, Kocher , because in the west- south-west a (different!) Lanzenbach also feeds the Bühler, in the west the Echtbach and in the northwest the Steppach its tributary Aalenbach .
On about a third of the catchment area, almost only in the northwest and north, there is forest, which surrounds two somewhat larger meadow clearings. In the open corridor there is mostly grassland in the valleys, and more arable land on the accompanying plateaus.
With the exception of a forest gusset on this side of the Hackenberg slope and part of the forest area in the northwest, both of which are unpopulated and belong to the urban area of Vellberg , the significantly larger part of the catchment area is in the municipality of Frankenhardt . Settlement is limited to the hamlet of Steinehaig , which stands on the western watershed, Waldbuch right above the middle course and a little downhill Bonolzhof on the flat mouth of the Seebach. Also from the village of Oberspeltach , where all of the above-mentioned are located, a small part on the left bank of the Buchbach drains to it. The hamlet of Spaichbühl is located close to the edge of the southeastern scabbard in the Gründelhardt district mark .

geology
The catchment area of the Buchbach lies entirely in the Keuper . The small high plateau on the Hackenberg a little above the source is covered by the silica sandstone ( Hassberge Formation ), below on the slope are Untere Bunte Marl ( Steigerwald Formation ), in the border area between this and the even deeper reed sandstone ( Stuttgart Formation ) the Buchbach rises. Around where the brook crosses the Steinehaig – Kleinaltdorf road, it changes to the Gipskeuper ( Grabfeld formation ), which is present in most of the catchment area, except only
- above the upper reaches of the large right tributary Seelesbach in the vicinity of the Hahnenberg , where the same sequence of layers is present on the slope downwards;
- left of the Buchbach upper course on the spur light oaks and on the Höcker Himmelreich right of the Seelesbach upper course near Spaichbühl, on which reed sandstone lies;
- on sections of the upper runs that are surrounded by areas of redistributed and weathered rock and
- in the ribbons of floodplain clay that accompany the three big runs from the middle run at the latest.
In some places the Gipskeuper shows a clear step formed by the thin, but dolomitized and therefore erosion-resistant Corbula Bank (formerly: Engelhofer Platte ), especially above the Seelesbach and on the lower reaches from the Bonolzhof, where there is one on both sides over the broad and flat valley basin sharp upper slope edge is formed.
Nature and reserve
The Buchbach, classified according to the type of flowing water as a fine-material, carbonate low mountain range , has only sporadic tree and shrub growth on the bank and a slightly winding course outside the two forest sections on the upper reaches. Two older maps show that the lower course between the inflow of the Seebach and the confluence with the Lanzenbach used to be quite winding and must have been straightened sometime between the mid-19th century and the mid-1930s.
Part of the area of the natural monument Geschäufelter swamp on the plateau of the northern Hahnenberg is just in the southwest corner of the catchment area above the origin of the Seelesbach. The center of the natural monument is a little deep still water surrounded by bushes and then high forest in a former farmer's sand pit, over which dragonflies sometimes stand in summer . The pond drains only periodically southwards over the Hahnenbach to Nesselbach and Bühler.
