The Eisenbach is a brook less than two kilometers long in the area of Rosenberg in the Ostalbkreis in northeastern Baden-Württemberg , which flows into the upper Blinde Rot from the left and northeast just before Hof Willa of the municipality .

geography

course

The Eisenbach flows together from two source streams running in small Keuper sound . Both origins lie a little west of the Hummelsweiler –Willa road in the Eisennagel forest at around 500– 495  m above sea level. NHN at the section between the forest entry of the road and the Judenbrückle , where this reaches the old route of the L 1060. The blade on the right, about 0.4 km longer, runs southwest, while the left, about 0.3 km shorter, runs westwards. A few steps before the source streams meet, they each pass through a pond dammed behind the embankment of a forest path; Main hiking trail 4 of the Swabian Alb Association , which is bundled with the Franconian-Swabian Way of St. James, runs along the forest path . The combined stream continues to flow in a south-westerly direction and soon crosses another, noticeably larger, reservoir.

After a good half of its total run, the Eisenbach leaves the forest into the clearing island of Willa, where the Harbach runs to it from the right , also a forest stream that is even a little longer than the Eisenbach to this point. The border between the Harbach forest of the Frankenhardt community on his right and the Rosenberg iron nail on his left runs along it for a long time . Near the left bank of the Eisenbach river, the forest continues to the slope opposite the Hochtänn farm . After a short underground run under the newer agricultural buildings of the soon to be followed hamlet of Zollhof , a tree gallery begins, which accompanies and expands from there. A quarter of a kilometer later it flows between Zollhof, which occupies the front mouth spur, and the Willa, which lies slightly downwards, in a deeply buried bed at about 457.8  m above sea level. NHN from the left and northeast into the upper blind red .

The Eisenbach flows about 37 meters below the origin of the left upper course after a total of 1.7 km, its mean bottom slope is about 22 ‰.

Catchment area

The Eisenbach drains an area of ​​2.0 km² in the northwest of the lower natural area of ​​the Ellwanger Mountains in 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. Forest in Gewann Eisennagel extends over about five sixths of the area and beyond the Harbach also in Harbach , only the lowest catchment area around Hochtänn and Zollhof is open.

The with about 518  m above sea level. NHN highest point is its northernmost point. From there to the mouth, the watershed runs to the right of the Eisenbach in the northwest towards the approaching Blinde Rot , who runs to the Kocher . Behind the left watershed in the southeast, its next left tributary Kaltenbach 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 .

Settlement is limited to the Hochtänn farm and the part of the small hamlet of Zollhof in the Rosenberg community , to which three quarters of the catchment area also belong, the rest to the right of the Harbach lies entirely in the Harbach forest of the Frankenhardt community in the neighboring district of Schwäbisch Hall .

  • Harbach , from the right and finally northwest to about 468  m above sea level. NHN at the exit of the Eisenbach forest east of Hochtänn, 1.5 km and approx. 1.0 km². (The Eisenbach itself has a length of only 1.0 km up to this point and a partial catchment area of ​​approx. 0.8 km².) Arises at around 505  m above sea level. NHN in the northern Eisennagel and flows in a somewhat to the right sweeping arc southwest.

Mouth of the Eisenbach from the left and northeast to about 457.8  m above sea level. NHN between Zollhof and Willa in the upper Blinde Rot . The Eisenbach is 1.7 km long from the beginning of its left upper course and has a catchment area of ​​2.0 km².

Nature and protected areas

After its unification, the Eisenbach flows mainly near-natural below the large reservoir and deeply deepened at the lower reaches, it has the sediment of sand and gravel that is typical of the Sandkeuper.

The open lower basin part, except for the settlement areas, for the conservation area Upper blind Red valley .
