The Harbach is a half-kilometer forest stream with approximately southwestern running on the municipal boundary of Rosenberg in Ostalbkreis to Frankenhardt in the district of Schwäbisch Hall in the northeastern Baden-Wuerttemberg , which close the yard Hochtänn of Rosenberg from the right in the Eisenbach flows.

This Harbach runs on the southern edge of the great Frankenhardt Waldgewannes Harbach about southwest and drains to Blinden Rot , while another Harbach runs almost on the northern edge of the same Gewann eastward; this other is the uppermost main line section of the Sulzbach, which drains to the Jagst .

geography

course

The Harbach arises at about 505  m above sea level. NHN approx. 0.4 km northwest of the entrance to the forest of the road Hummelsweiler - Willa in the Eisennagel coniferous forest on the Rosenberg district. It flows a quarter of a kilometer westwards and then bends to about 491.1  m above sea level. NHN on a long south-westerly run, during which it is Grenzbach between Rosenberg and the Eisennagel forest on the left and Frankenhardt and the Harbach on the right. On this approximately one-kilometer-long section of its course, it flows over a sandy bed up to one and a half meters wide, winding through what will soon be a very wide valley heir. The main hiking trail 4 of the Swabian Alb Association , which is bundled with the Franconian-Swabian Way of St. James, crosses it on the stage between Burgberg and Hohenberg on a specially constructed wooden walkway. Where the forest ends at the clearing island around Willa , it turns left at the Forchenwäldle and then flows a quarter of a kilometer in a ditch between pastures to the southeast. It then flows 0.3 km northeast of the Rosenberger Hof Hochtänn at about 469  m above sea level. NHN from the right into the middle Eisenbach , which has just left the iron nail here.

The Harbach is 1.5 km long, flows out about 36 meters above sea level below its origin and thus has an average bed gradient of about 24 ‰. It has no significant inflows. In comparison with the Eisenbach-Oberlauf up to the confluence, the Harbach lies after both its length (1.5 km to only 1.0 km), its catchment area (approx. 1.0 km to only approx. 0.8 km) and its source height ( 505  m above sea level to only approx. 495  m above sea level ) on the main line of the Eisenbach, but is officially regarded as its inflow according to its water body number .

Catchment area

The Eisenbach drains an area of ​​about 1.0 km² in the northwest of the lower natural area of ​​the Ellwanger Mountains of the Swabian-Franconian Forest Mountains . In this keuper bergland are here the layers of exchange sandstone ( Lowenstein formation ), the upper Bunte marl ( Mainhardt formation ) and at the bottom of the quartz sandstone ( Hassberge formation ) to. About 90% of the area is covered by forest in Gewann Eisennagel and Harbach , only the lowest catchment area near Hochtänn is open.

The with about 518  m above sea level. NHN's highest point is its northernmost point near a water reservoir. From there on, the watershed to the right of the Harbach in the north-west separates the watershed from the direct catchment area of ​​the pre-receiving waters Blinde Rot , which runs to the Kocher . Behind the left watershed in the southeast, the upper reaches of the Eisenbach outflow drains the adjoining area. The hydrologically most important border lies in the east, beyond it, the left upper course of the Glasbach flows over the Orrot to the upper Jagst .

There is no settlement on the bank or in the catchment area, around half of which belongs to Rosenberg and Frankenhardt.

Nature and protected areas

The small open land area near the mouth of the river belongs to the nature reserve Upper Blinde-Rot-Tal .
