The Mühlbach is an almost one kilometer long stream in the Großaltdorf district of the small town of Vellberg in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows south into the Aalenbach from the right between Kleinaltdorf and the Aussiedlerhof Sonnenhof .

geography

course

The Mühlbach arises on the south side of the Kerlewecker Weg approximately opposite the Aussiedlerhof in Mönchswiesen on the other side of the road at about 399  m above sea level. NHN . It runs its first almost one hundred meters between a meadow on the left and a field on the right under a loose field hedge to the south and then crosses under the Crailsheim – Heilbronn railway line, which is accompanied by dirt roads on both sides, with hedges growing on both sides of the dam. On the other side of the railway, for almost half a kilometer, it follows a field path that stretches to the west in its valley through the Mühlenbach field and south to the L 1040 Großaltdorf– Talheim . After crossing under the main road, it flows for the next hundred meters between a meadow on the left, which is bordered on the other side by a municipal road that is also lined with hedges and connects the main road with Kleinaltdorf, and a field on the right to the southeast. On the access road to the Sonnenhof in the south, which is then reached, the brook flows out of its ditch into a hollow, in which it runs southwards for the rest of its course under the narrow meadow meadow of the small river, known here as blue meadows, before it rises to about 373  m above sea level. NHN below Kleinaltdorf and above the Sonnenhof leads from the right into the Aalenbach, which is accompanied by a gallery .

The Mühlenbach flows after a 0.9 km long run with an average bottom gradient of about 30 ‰ about 26 meters below its origin on Kerlewecker Weg. Apart from ditches along the L 1040, it has no open tributaries.

Catchment area

The Mühlenbach has a catchment area of ​​around 0.5 km², which in terms of natural space lies in the lower area of ​​the Haller level of the Hohenloher and Haller levels . The area is open and is mainly used for arable farming. The little over 420  m above sea level. NHN highest point is a little northeast of the Aussiedlerhof at the origin next to the K 2665.

In turn, the catchment areas of the following neighboring waters are adjacent:

  • In the north, a little behind the watershed, the upper course of the high plateau of the stream runs through the Kappisklinge westwards to the Bühler ;
  • in the east, the settlement area of ​​Groß- and Kleinaltdorf, which slopes down to the south, borders on, in which there are no open waters to the Aalenbach ;
  • in the southwest a nameless stream runs through the Gewann Unteres Breitfeld , now below the Mühlenbach estuary, also to the Bühler tributary Aalenbach;
  • in the west the Binsenwiesenbach arises near Kerleweck , which feeds the Bühler between Aalenbach and Kappisklinge near Neunbronn .

The entire area lies within the boundaries of the Großaltdorf district of Vellberg .

geology

In the area of ​​the northern watershed, on which roughly the K 2665 Großaltdorf- Oberscheffach runs, lies a narrow strip of loess clay from Quaternary deposits. To the south of it, almost to the Aussiedlerhof at the source of the stream, Gipskeuper ( grave field formation ) covers the higher elevations. In the vast majority of the remaining and deeper catchment area, Lettenkeuper ( Erfurt formation ) is due. On the bottom of the creek hollow soon after the railway crossing, a strip of alluvial land stretches, near the mouth of the Aalenbach run, then its floodplain. Its floodplain is possibly even deepened into the Upper Muschelkalk , because this is proven to be both a little above and a little below the Mühlenbach inlet on the lowest slope of the Aalenbach.

history

A measuring table sheet before the land consolidation from the first half of the 20th century shows two sources of the brook still north of the Kerlewecker Weg in the area of ​​the overbuilding of today's Aussiedlerhof and one of these two sources from the east, about 0.3 km long, which has now disappeared Upper course to the present origin. According to this map, on the section between the railway line and the state road, the Mühlenbach ran in a jagged course in a strip of meadow in the middle of its natural hollow; on the other side of the main road it already had its current route back then, but there it was still open over its entire length and accompanied by meadows on both sides.

The name of the creek, which is completely uninhabited today except for the Aussiedlerhof, near the origin, suggests that a mill could once have stood on it. However, this is neither entered on the relevant sheet of the map of the Kingdom of Württemberg from 1858 nor on the sheet of the measuring table from 1931. The Oberamtsbeschreibung from 1847 only mentions one mill for the then community of Groß-Altdorf, which was located in Kleinaltdorf half a kilometer above the Mühlenbach tributary on the significantly more water-rich Aalenbach.
