The Dietelsbach is a 3 km long brook on the municipal markings of Obersontheim and Bühlertann in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which, coming from the west-south-west, flows into the middle Bühler from the left at the boundary of the district .

geography

course

The Dietelsbach arises a few meters next to the hill saddle, over which the state road 1066 leads from its sub-town Mittelfischach to Obersontheim, in an often very dry, loamy channel of the western Enslinshalde at about 414  m above sea level. NN . The gully runs to the east, like the stream itself for almost the first half of its way. For the first two to three hundred meters it steps out of the forest to the edge of the corridor, changes completely to the open corridor and then has a constant flow. At about the level of the first field, the profile of its meadow hollow shows a former small pond. Completely without woody vegetation, it moves next to the irregularly undulating, flat hills of the Galgenwasens to the left, on which there are often fields, in a few lazy turns through the soon-to-be-quite flat meadow further below the higher rising Enslinshalde. His bed here is narrow but deeply furrowed, but numerous shrubs rise from the trough; in spring the marsh marigold blooms here in a bright yellow . About 1.2 km below its uppermost origin, the stream runs after Grabenlauf with a long backwater in an almost flat meadow, at about 391  m into a 0.1 hectare pond at the east end of the Enslinshalde , which is on three sides by the forest and one Field hedge is enclosed and has a small island.

After flowing out of the pond under an unpaved field path, the brook strives to the northeast, now a little further on the Bühlertanner district, initially in a flat meadow in a drawn, deep ditch until it crosses under the state road 1060 Obersontheim- Hausen -Bühlertann . Behind the two to three meter high road embankment, on the left bank, there is an approx. 0.2 hectare large pond, which was artificially created in the first decade of the 21st century as part of the industrial development of the left hill. The Dietelsbach soon flows in a deep, natural meadow bed in a wide hollow between the slope with the Obersontheimer Gewann Steinich ( 397.4  m ) on the left on the ridge and the Bühlertanner Alten Galgenberg (approx. 397.4  m ) on the right, on which the pit a plaster quarry that was abandoned in the second half of the 20th century is exposed. From then on, the course, which follows the municipality boundary with deviations, also shows natural windings and repeated vegetation with bushes, especially from willows. This is followed by a section in which a 0.9 hectare swamp sedge runs along the brook on the left bank. At some point around the turn of the 21st century, a very irregular pond area was created in the lower part by means of clay dams. The entire reed area is said to be in the area of ​​an ice pond of a local microbrewery that was used until the 20th century.

Below there is an allotment garden zone, about two hundred meters long without a fence, on the left, which rises flat to moderately towards the slope, while the opposite valley flank becomes significantly steeper. The stream passes the first residential building on its bank, 50 meters later it runs in a pipe under the K 2612 Bühlertann – Obersontheim and beyond under a second residential building. At the end of its small property garden, it steps outside again and flows a stone's throw further, last of all again on the east run, from the left on the boundary of the neighboring communities at about 368  m into the middle Bühler , which flows slowly here , only 50 meters downstream through the weir former mill is dammed.

The Dietelsbach is approx. 3.0 km long from its highest source, it has a bottom falls of approx. 46 m in absolute terms and approx. 15 ‰ in relative terms. It has an open inflow only from short trenches. Almost nowhere do paths follow him.

Catchment area

The Dietelsbach drains about 1.3 km², predominantly in the lower area of ​​the Vellberger Bucht of the Hohenloher Ebene natural area, east and northeast to the Bühler, which drains the bay. The smaller part is on the upper reaches in the lower area of Fischach Bay and edge heights . The watershed to the adjacent catchment areas is nowhere very high. In the north, the Obersontheimer Schießbach competes with the downward, in the south the Eierbach, which flows out at the Bühlertanner Niedermühle, competes with the upward Bühler. The southwestern watershed over the Tannenberg ( 441.1  m ) at the height of the Enslinshalde forest slopes runs towards the valley of the much more important Fischach , which also flows much further upwards to the Bühler. The highest point in the catchment area is here on the Tannenberg, which is quite flat at the top.

Forest stands on less than a quarter of the area, mainly on the Enslinshalde slope . In the corridor, the meadows dominate, fields are mainly to the left of the upper course in Galgenwasen , in the hilltop Steinich to the left of the lower course and on the slope there. Obersontheim and Bühlertann share the catchment area. The already mentioned two houses shortly before the estuary and a third one near the estuary are the only settlements on the run and at the same time in the catchment area, they are isolated south of the Obersontheim locality on this side, on and on the other side of the municipality boundary.

geology

The Dietelsbach begins its course in the Gipskeuper ( Grabfeld Formation ), a few meters below its layers of estheria, which spread out over the top of the Tannberg and often elsewhere in the wider area. The small hills along its upper course show the restless shape typical of the plaster keuper. In the long-abandoned gypsum quarry on the Galgenberg to the right of the middle course, the layers from the border dolomite of the underlying Unterkeuper to the base gypsum once exploited here and up to the lowest dark red marl of the Gipskeuper are exposed. The base gypsum shows subrosion, and the loamy marl layers above it showed that it had previously warped. The Unterkeuper begins in the valley shortly before crossing under the L 1060, the stream remains in this layer position up to the mouth. A few dozen meters north of this, the Upper Muschelkalk appears for the first time in the Bühlertal . Floodplain sediments accompany the stream from about the onset of the Unterseuper.
