The Heiligenbach is a 3.7 km long brook on the Hohenlohe Plain in northern Baden-Württemberg , which joins the right and western Sperbersbach near Untermünkheim in the Schwäbisch Hall district to form the short Dobelbach , which soon flows from the left into the middle Kocher in the village flows out.

geography

course

The Heiligenbach arises in an unsteady course on the K 2565 from Braunsbach -Herdtlingshagen to Untermünkheim-Gaisdorf about 300 meters south of its bridge over the A 6 at about 430  m above sea level. NN . At first only very slowly deepening, it runs for about two kilometers, accompanied by a very patchy wood gallery, between the cleared arable land to the southwest. Then he occurs at about 385  m above sea level. NHN in its steep and forested limestone - blade one, here for the first time it performs quite resistant to water. The blade deepens on the first kilometer to about 320  m above sea level. NHN a. Then the B 19 crosses it , which emerges from a small right-hand side cliff from the plateau into the valley and follows it on the left slope, then also the Dobelbach to its mouth. On the remaining 700 meters of its course, Heiligenbach and its blade make an arc to the left, on a south-east course it then runs with the Sperbersbach, approaching from a blade from the west, at 288.3  m above sea level. NN at the lower edge of the valley forest and shortly before Untermünkheim together. The resulting Dobelbach continues to flow in the direction of the Heiligenbach and flows into the middle Kocher after about a kilometer through the village.

The Heiligenbach is shorter than the Sperbersbach, but has more catchment area, it is seen as the main hydrological source of the Dobelbach.

Catchment area

The Heiligenbach has a catchment area of ​​4.2 km². Beyond the watershed in the northwest, the upper copper drains , in the north the Eschentaler Bach , in the east to southeast of the catchment area two smaller razor tributaries (Geißklingenbach, Enselbach) and otherwise only short gullies and slope channels like the other competitors mentioned to the Kocher.

The largest elevation in the catchment area is a flat hilltop, marked by a power line mast, at its northeastern tip near the A 6 at 436.8  m above sea level. NN . Most of the area is open land on the flat hilly Hohenlohe plain, which is predominantly plowed; the proportion of forest is limited to a little over 0.4 km² of sea ​​wood on the northern watershed, a little over 0.3 km² of Klingenwald on the lower reaches and the Krappenholz forest island, only about 4 hectares in size, on the right above the middle course.

Settlements in the catchment area are only the northern end of the hamlet of Gaisdorf and the rest of the house Steigenhaus at the upper end of the side blade used by the B 19, they both belong to Untermünkheim as well as almost the entire area . Otherwise only the community of Braunsbach has a tiny share, about 2 hectares of arable land on the northeast corner with the highest point belong to it.

Tributaries and still waters

About one kilometer after its origin, the Heiligenbach runs from the left to a ditch from the direction of Gaisbach; it, like the entire course of the Heiligenbach up to its entry into the blade, only carries inconsistently water. The tapering riser blade of the B 19 is steeply buried, but the main road that fills the entire base of the blade is only accompanied by mostly dry trenches. At the northern edge of the Krappenholz lies on a flat knoll against the upper copper to a pond of less than 0.1 ha without a clear direction of drainage.

geology

The Heiligenbach arises in a Quaternary loess sediment layer of the Lettenkeuper ( Erfurt Formation ), in which it then runs in a wide hollow next to the ridges covered with loess sediment until it enters the ridge. There it reaches the Upper Muschelkalk and only shortly before the confluence then the Middle.
