The Amsbach is a two-kilometer long stream in the district of the town of Gaildorf and the municipality of Obersontheim in the district of Schwäbisch Hall in north-eastern Baden-Württemberg , which flows into the Bühlbach from the right near the Obersontheimer Höfe Rappoltsau and from the west-southwest .

geography

course

The Amsbach arises about one kilometer north of the Gaildorf hamlet of Winzenweiler on a very flat, damp part of the wooded plateau of the Limpurg Mountains at about 500  m above sea level, with drainage ditches in the terrain, often of unclear drainage direction . NHN . The run begins about 200 meters west of Haspelsee and, with small changes in direction, moves eastwards to the 1.3 hectare reservoir, which is managed by a fishing club and popular with forest visitors in summer, which it then flows through. At the dam in the west next to the coal road , it leaves it through a small alder quarry, flows a little further on after crossing the forest path, whereupon at about 490  m above sea level. NHN begins its steep course through a narrowly incised forest blade .

In this it changes after less than half of its length to the Obersontheimer district. Half a kilometer later the slope becomes flatter to less than 440  m and the stream first comes out on the right edge of a narrow meadow tube and then into this, whereupon it moves along with almost no woody vegetation and right next to a gravel farm road. Even after a quarter kilometers runs up again at the left edge of the corridor forest inlet along, where he soon an elongated pond of less than one Ar feeds surface. While the valley floor opens to the right more and more to the flat agricultural plain around Rappoltsau , the stream turns through the last Spöck forest spur to the north. Two hundred meters further on, the stream reaches the edge of the forest on the other side to a damp meadow lowland on the right bank, after another hundred meters the Amsbach flows out at about 424  m above sea level. NHN from the right into the Bühlbach , which then on its eastward course a little downhill crosses the Engelhofen - Rappoltshofen road (K 2622) near Rappoltsau in a pipe.

The Amsbach is about 2.1 km long and has a bottom gradient of about 76 m in absolute terms, relative to about 37 ‰. After a few drainage ditches with an almost stagnant flow that reach him or the Haspelsee on the plateau, apart from temporary sloping channels, it no longer has any significant inflows.

Catchment area

The Amsbach drains about 1.1 km² in the east-north-east to the Bühlbach, most of which is in the Limpurger Berge natural area at up to 514.4  m above sea level. NHN reaching plateau around the Haspelsee and on the western slope of the low mountain range, to a lesser extent in the upstream nature area Fischachbucht and edge heights of the lowland, which is also part of the extensive Keuper landscape natural area of ​​the Swabian-Franconian forest mountains . It borders the immediate catchment area of ​​the receiving stream Bühlbach in the north and the Engelhofener Breitenbach in the southeast via its inlet Klingenbach , both ultimately draining east into the Fischach . The competitors still following in the district around the catchment area are all tributary to the Kocher without detour via Fischach and Bühler , namely in the south-west the left upper reaches of the Rotklingenbach of the Eisbach flowing from Winzenweiler to Sulzbach-Laufen and in the west of the Eutendorfer Bilmersbach , which flows into the Steppach there as well as the left upper course of the steppach itself in the goat blade .

The highest point in the catchment area is on the northwest tip on the plateau, which is mostly over 500  m , in front of the Geißklinge at about 513  m . The area, with the exception of only a narrow corridor around part of the lower reaches, is forested and nowhere populated. Once there was a place Haspelhausen in the area of ​​the Haspelsee , but it disappeared centuries ago. Over two thirds of the area belong to the town of Gaildorf, the rest on the slope in the east to the municipality of Obersontheim .

geology

The Amsbach runs entirely in the Mittelkeuper . Its origin lies on the silica sandstone plateau ( Hassberge Formation ), its blade barrel quickly cuts through the underlying layer package up to the gypsum keuper ( grave field formation ), in which it also flows.

Protected areas

After its blade emergence, the Amsbach flows in the Fischachtal landscape conservation area with side valleys and adjacent areas between Herlebach and Kottspiel .
