The Eichelbach is a 4 km long brook in the Rems-Murr-Kreis in northern Baden-Württemberg , which flows into the middle Murr from the left at the hamlet of Aichelbach in the municipality of Oppenweiler after a very precise western run .

geography

course

The Eichelbach arises about 0.6 km west-northwest of the Eschelhof hiking home on the plateau of the Murrhardt Forest around the hamlet of Ittenberg in the municipality of Sulzbach an der Murr at about 476  m above sea level. NN in the forest near a clearing around a forest house. He consistently flows in a westerly direction and cuts soon in Won Einsiedel in a forest sword . After about 800 meters, it flows into this from the south to only about 387  m above sea level. NN a steep, only periodically water-bearing blade crack from the Gewann swamp forest , the bed of which follows the municipal boundary to Oppenweiler, which the Eichelbach now crosses.

After a further 700 meters, which is now followed by a farm road to the right, the Eichelberg right slope opens into an orchard landscape in which numerous rows of trees pull down this southern slope of the right Köpfle spur , while the Greut forest is still adjacent to the left. The brook now mostly runs close to nature in an initially very wide tree gallery, which then narrows after the end of the Greutwald, consisting mainly of black alder and ash to the outskirts of the Oppenweiler hamlet of Aichelbach (!). There it is twisted, crosses the Schwäbisch Hall-Hessental-Waiblingen railway line and then the Zeller Straße and then flows open again in the local area. After it has crossed under the valley path at the end of the village on the river side, it flows for about 200 meters between two fields, accompanied by trees, over the left flood plain and finally flows out at about 243  m above sea level. NN from the left and east into the middle Murr ; Opposite is the Staigacker nursing home in Backnang on a hilltop .

After its distance of 3.9 km, covered with a mean bed gradient of about 60 ‰, the Eichelbach flows about 233 meters below its origin.

Catchment area

The Eichelbach has a catchment area of ​​2.3 km², which is mainly in the sub-area Murrhardter Wald of the Swabian-Franconian Forest Mountains natural area , with the part near the mouth in the sub-area Outer Backnanger Bay of the adjoining natural area Neckar basin . The highest elevation in it is the folding rule ( 543.7  m above sea level ) on the southeast corner, beyond which the catchment area of ​​the Brüdenbach , which drains further downstream into the Murr via the Weißach, borders only briefly . Behind the southern border, the next left Murr tributary, Frauenklingenbach, flows roughly parallel to the Eichelbach, a little below Zell. In the north, the border separates from the drainage area of the opening into the Weiler Reichenbach next upper tributary Reichenbach der Murr, while the area beyond the eastern, mostly only on the activities Berger Bach , from Eschelbach drained to this.

A good third of the catchment area are forest areas in the east and on the narrow spur of the Köpfles in the north, in the area of ​​the municipality of Sulzbach am Kocher , the rest with the only place Aichelbach in it is on Oppenweiler municipality marker . In the Oppenweiler part, the open parts in the Murrtal and on the northern valley slope below the Köpfle dominate slightly opposite the forest on the middle course and on the left mountain spur. The Eichelsberg southern slope of Köpfles called down to orchards move into the upper valley to mix on the Murr in the agricultural corridor meadows and fields.

Tributaries

The Eichelbach has only one major tributary:

  • (Unstable forest stream), from the left and south to about 386.6  m above sea level. NN in the forest area of Einsiedel , approx. 0.4 km and approx. 0.3 km². Arises at about 510  m above sea level. NN in the Gewann swamp forest . The main stream upper course of the Eichelbach is more stable, up to this point about 0.8 km long and has a catchment area of ​​about 0.4 km².

This brook running in a steep ridge is the border between the communities Sulzbach an der Murr and Oppenweiler, in whose area the flowing Eichelbach crosses the loop of a farm road that opens up the forest from below on both sides of the slope.

geology

The Eichelbach runs through the Mittelkeuper from the Stubensandstein ( Löwenstein Formation ) on the plateau of the Murrhardt Forest down to the Gipskeuper ( Grabfeld Formation ) in the Murrtal; A little further down from the estuary, at the next valley town of Zell am Lauf der Murr, the Lettenkeuper ( Erfurt formation ) of the Unterkeuper begins . After a reasonably long stretch on the Stubensandstein, the stream cuts through the strata from the Upper Bunten Marl ( Mainhardt Formation ) immediately below it to the last layer above the Gipskeuper, the reed sandstone ( Stuttgart Formation ), relatively quickly before it between the blade inflow from the south in the Einsiedel forest and its exit in the Gipskeuper the flatter lower over two thirds of its course begins.

Shortly before the exit of the forest, on the left and shortly after this on the right, there is an island of slipped material from higher layers on the lower slope. Shortly afterwards, the loess sediment from Quaternary deposits typical of the Backnang Bay covers the tertiary gypsum keuper layer. In the hamlet of Aichelbach, the brook created a confluence fan in the area of ​​the floodplain sediment band next to the Murr, which flows south here, which caused the river to give way to the west in an arc.

On the slope debris island to the left of the Eichelbach, a geological fault line pulls into the catchment area from the southeast, with the deep floe in the northeast, which, however, apparently no longer crosses the stream itself.

Protected areas

The entire catchment area lies in the Swabian-Franconian Forest Nature Park . The largely open hillside below the glans Köpfle-spur is right as a conservation area Eichelsberg reported.
