The Hirtenbach is a four kilometer long stream on the Sulzdorf district marking of Schwäbisch Hall and on its edge in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the Bühler from the left before Sulzdorf-Anhausen .

geography

Source and history

The source area of ​​the Hirtenbach is located southeast of the Hehlberg and northeast of the Birkentöbele ridge , near the road K 2627 Sulzdorf – Herlebach, at around 435  m above sea level. NHN in the Höning forest area . From there the young brook flows between Heidelberg in the north and Burkhart in the south through the Winterklinge towards east-northeast. After about a kilometer, it reaches the corridor boundary, where it feeds a pond less than 0.1 hectare in size and crosses the grounds of the Dörrenzimmern golf course.

In the same direction, it crosses this, spanned by a small stone arch bridge at the club building, then crosses under the L 1060 and flows through the hamlet of Schwäbisch Hall- Dörrenzimmern . After that, in the meantime in a small depression in the terrain, which is particularly noticeable on the right-hand side, it moves on in a north-easterly direction and past the Haller hamlet of Buch on the right ridge, after which it crosses the Crailsheim – Heilbronn railway and the K 2602 Sulzdorf– Buch at a former stationer's house .

Less than 0.6 km later, it feeds an almost 0.1 hectare fish pond and abruptly turns north-northwest. On its last 0.3 km it deepens in a wooded ridge by almost 30 meters in altitude and then flows, about 300 meters southeast of Sulzdorf- Anhausen , on a poorly accessible southern impact slope of the same at about 318  m above sea level. NHN from the left into the Bühler . In the Middle Ages, the castle of Buch stood on the pointed mouth to the right , of which hardly anything can be seen in nature today.

The Hirtenbach flows after a 3.9 km long run with an average bottom gradient of about 30 ‰ about 117 meters below its origin.

Catchment area

The shepherds Bach has a catchment area of 2.1 km², the natural area considered at the top of the subspace Limpurger mountains of the Swabian-Franconian Forest Mountains counts, with the middle and lower catchment area for subspace Vellberger Bay of Hohenlohe and Haller level . The 504  m above sea level. NHN's highest point is on the northwest corner on the Hehlberg plateau .

The catchment area is in the form of a tube of little fluctuating width around the stream running to the northeast. On the left, northwest side it borders on that of the Sulzdorf Schwarzenlachenbach ; Across the first two thirds of the run, beyond the watershed, which in the area of ​​Dörrenzimmern is sometimes less than five meters above the bed of the Hirtenbach, competes with its right tributary, the Erlenbach . Only in the far north does a tiny Klingenbach, which begins as a ditch alongside the field, push itself directly to the Bühler.

On the other, right-hand side, no other tributaries compete with the Bühler from the mouth up to Buch on the right, there are only temporary sloping channels here. Above Buch, the catchment area of ​​the short Bühler tributary Bärenbach borders in the east , and further upstream the Vellberger Steinbach , which also flows into the Bühler and rises just a little south of it in a similar location to the Hirtenbach. Beyond just a short stretch of western watershed on the Birkentöbele ridge and part of the Hehlberg that still rises above it, the Fischach to the Bühler flows much further upstream.

geology

The source area of ​​the Hirtenbach lies on one of the typical damp slopes in the upper Gipskeuper ( Grabfeld Formation ) below the reed sandstone ( Stuttgart Formation ), which covers the Birkentöbele ridge in the far west. Above this, in the Hehlberg sector, which is still just in the catchment area, there are Obere Bunte Marl ( Mainhardt Formation ) on the slope and silica sandstone ( Hassberge Formation ) on the plateau.

The two mountain foothills framing the Hirtenbach upper reaches of Heidelberg in the north and Burkhardt in the south are covered by the leveled areas of the Corbula Bank of the Gipskeuper. The Hirtenbach then reaches the Unterkeuper around the end of Dörrenzimmern at the beginning of its basin, the Upper Muschelkalk between the railway line and the fish pond on the lower reaches.

Between its exit from the forest and Dörrenzimmern, the stream has deposited a partly wide zone of much younger Quaternary floodplain sediment above the Gipskeuper . With the bend in direction at the fish pond below Buch, the brook follows the so-called Vellberg fault, which moves northwest; a little before that, a small parallel disturbance crosses the creek trough.

Nature and protected areas

The upper course lies in a fairly flat forest valley in which the coniferous forest dominates. From the field boundary, the stream flows through meadows, mostly accompanied by bushes on the banks. The brook runs through drying rooms in an open course between houses and farmsteads that are not very close together. The small valley basin between Dörrenzimmern and the railway line is mostly used as animal pasture, here you can sometimes see small forests of glandular balsam between the overgrown bank area . The accompanying hills are plowed. Before crossing the railway line, there is a small spring moor on the right, which is protected as an extensive natural monument . The remaining open area on the lower reaches belongs to the protected landscape Bühlertal between Vellberg and Geislingen with side valleys and adjacent areas to the following brief Forest blade portion from around the fishpond to the nature reserve Lower Buhlertal .

Inflow system

Except for the often dry, depending on the season of the year, small valley hollows from the two mountain ridges on both sides, the longest of which begins not far from the hiking car park under the Hehlberg on the L 2627, the Hirtenbach only has an inflow from nearby sources on the middle and lower reaches.

Localities

The Hirtenbach with its bed and catchment area is located in the Sulzdorf district of the city of Schwäbisch Hall , with the exception of the right side of the Bach and Mündungsklinge, which is part of the Vellberg district. The Vellberg part of the catchment area covers less than 1.4 hectares and borders the lowest course on only about 0.2 km.

The only settlement on the stream itself is the hamlet of Dörrenzimmern .
