The Sperbersbach is a 4.4 km long brook on the Hohenlohe plain in northern Baden-Württemberg , which joins the left and northern Heiligenbach near Untermünkheim in the district of Schwäbisch Hall to form the short Dobelbach , which then soon flows from the left into the middle Kocher in the village flows out.

geography

course

The Sperbersbach arises about 2.0 km northwest of the center of Schwäbisch Hall - Gailenkirchen on the eastern slope of the Waldenburg mountains to the Hohenloher level below the Kreuzstein at about 440  m above sea level. NHN . It flows quickly down about 20 meters in altitude to the edge of the meadow and then in the meadow always close to the southern edge of the eastern forest ledge around the copper moor in the north to the east. After about 2 km it dissolves at about 370  m above sea level. NHN from the edge of the forest, which is now field-bounded, and then first crosses the Heilbronn – Crailsheim railway line , then the Schwäbisch Hall western bypass K 2576.

In a constant westerly course, it touches the southern edge of the Untermünkheim hamlet of Wittighausen. Here, at about 355  m above sea level. NHN , he crosses the Alttrasse the K 2576 and enters, accompanied by the K 2575 after Untermünkheim, abruptly into its steep and narrow forest sounded one. To the left above this is the Wittighausen quarry, not visible from the blade. After about 1.3 km east of the gorge, during which the county road crosses it once, it flows to 288.3  m above sea level. NN a little before the outskirts of Untermünkheim with the Heiligenbach to Dobelbach , also coming from a forest blade last from the northwest . After crossing the village, this flows into the middle stove about a kilometer further from the left .

The Sperbersbach is longer than the Heiligenbach, but has less catchment area, which is why the Heiligenbach is regarded as the main hydrological source of the Dobelbach.

Catchment area

The Heiligenbach has a catchment area of ​​2.7 km², which extends from the eaves of the Waldenburg Mountains in the far west about 4.0 km to the confluence in the east; across it it widens to a maximum width of about 1.1 km. Beyond the prominent and short watershed in the west, the Altenhaubächle flows to the upper Bibers . The northern borders the catchment area of ​​the upper copper . In the south, the Gailenkirchener Schmiedbach drains in a roughly parallel eastward course to the Kocher, which is also the receiving water of the others, but which reach it much further up or down.

The highest point in the catchment area is in Alten Hau on the edge of the plateau of the Waldenburg mountains at a little over 510  m above sea level. NHN . About 1.0 km² of the area are forests, four fifths of which are on the slope of the Waldenburg Mountains on an arc that begins earlier in the north to the west around the Auwiesen bay (forest basin Auwald and Wieselesrain in the north, Hebsack in the south), the remaining fifth is in the underflow blade. The open and flat hilly corridor is almost entirely under the plow.

The only settlement area is the hamlet of Wittighausen, which, like around half of the catchment area, belongs to Untermünkheim. Almost all of the remainder in the west is in the Schwäbisch Hall district, with the exception of only around 0.1 km² of the uppermost forest slope in the west, which is part of Waldenburg.

Tributaries and still waters

Source of the Sperbersbach at about 440  m above sea level. NHN . on the forest slope under the Kreuzstein and above the western meadow bay of the expulsions . The Sperbersbach has inconsistent water for about the first 1.5 km.

  • RiverIcon-SmallLake.svgFeeds three small ponds at 410  m above sea level. NHN at the entrance to the meadows , a total of 0.1 ha.
  • RiverIcon-SmallLake.svgRuns through a pond below 390  m above sea level. NHN on the edge of the meadow to the alluvial forest , 0.2 ha.
  • Inconsistent inflow, from the left and west-northwest at the edge of the forest at 376.6  m above sea level. NN , approx. 0.4 km. Arises in the alluvial forest at about 385  m above sea level. NHN
  • Inconsistent field edge ditch , from the left and west-northwest just before Wittighausen at 358.8  m above sea level. NN , approx. 1.1 km. Arises in the eastern tip of the alluvial forest at over 370  m above sea level. NHN
    • Meadow branch, from the left and east to 366.8  m above sea level. NN next to the western bypass, approx. 0.7 km. Arises at about 380  m above sea level. NHN in the Bühläckern on the old route of the K 2576 north of Wittighausen.

Confluence of Sperber creek on 288.3  m above sea level. NN about 300 meters west of the outskirts of Untermünkheim with the left Heiligenbach to Dobelbach.

geology

The Sperbersbach rises on the Keuperschicht stage slope in the west in the Gipskeuper ( Grabfeld Formation ) and only changes after the inflow from the alluvial forest to the Lettenkeuper ( Erfurt Formation ), which soon occupies the entire width of the catchment area, with the exception of only two overlying Quaternary loess sediment areas to the left of the Middle course. The run in the Upper Muschelkalk begins with his blade near Wittighausen . It only reaches the Middle Muschelkalk shortly before the confluence .

When the western bypass was being laid, an old tunnel in Lettenkeuper was cut near Wittighausen, which contains pyrite here and was mined in the 19th century to produce vitriol . The Wittighausener Muschelkalk quarry opens up the layers from the Upper Main Muschelkalk to the Lettenkeuper Main Sandstone. A sinkhole, created by leaching in the underlying Middle Muschelkalk, led to severe bending of the layer in the quarry area.
