The Eckertsbach is a brook mainly in the urban area of Backnang in the Rems-Murr district in Baden-Württemberg , which flows into the middle Murr from the right after a good 6 km long run to the south opposite the old town of Backnang .

geography

course

The Eckertsbach arises in the northeast of the Backnang basin at the transition to the Löwensteiner Mountains , which run out in a corner in the area of ​​the Pfaffenklinge towards the Backnang village Strümpfelbach . In this forest run quick succession of steep sides seem some all less than 0.4 km long small streams together, their sources at altitudes around 350  m above sea level. Arise from NHN . The one furthest from the mouth, which usually has a drain, is located a little east of the Strümpfelbacher Weg forest road . The Quellbach, which initially flows east of the Backnang city limits to the area of ​​the municipality of Oppenweiler bordering here to the north , soon turns south into the interior of the urban area and takes on the other spring brooks.

Then the Eckertsbach reaches the small Vorsee of the three immediately following forest lakes to the west under the Eulenberg- Sporn ( 385.8  m above sea level ). These four from fed at its western edge flowing past Eckert Bach and dehydrated, accumulated Heppseen are having together about 1.8 ha in size even at altitudes of about 320- 300  m above sea level. NHN . After the last, a meadow begins on the lower left slope of the valley, into which orchards mix. Soon the closed forest on the right bank also breaks out. A quarter of a kilometer further, the stream briefly runs through the enclosed Ottenseehau Park around Katharinenhof Palace , where it passes a small pond of less than 0.1 ha. After the end of the park, an approx. 0.4 km long open ditch with a partial catchment area of ​​approx. 0.3 km² runs from the west-northwest, which begins inconspicuously in front of the Trinkhau in Gewann Tobelt ; it is the only significant open inlet below the source branches.

Then it stretches almost free of trees and bushes on the bank in a meandering course towards the village of Strümpfelbach for over half a kilometer and then moves along the edge of the Weichbild of its old part of the settlement to Bundesstraße 14 from Sulzbach an der Murr to Backnang, under which it is located Junction of the district road K 1904, called Ludwigsburger Straße in the village , changes under the B 14 to its east side. He continues to follow the road to the south, the left bank touches the forest island of Seehau shortly before the first houses in the closed development of Backnang .

At the beginning of this industrial area in the Lerchenäckern, the long Sulzbacher Straße branches off from the main road that turns to the south-west towards the city center, which is followed by the stream behind the one row of houses on the east side. After less than ten buildings, the Eckertsbach then disappears in a doldrums in which it flows the remaining 2 km to the mouth in the first slowly, then more deeply deepening valley. Over the last three quarters of a kilometer, the built-up valley, which has been cut into an almost blade-like shape, even curves to the left.

After a 6.2 km long path, the Eckertsbach finally flows in Backnang under the bridge of Sulzbacher Straße to the old town at about 242  m above sea level. NHN and thus not quite 110 meters below its origin from the right into the middle Murr . It has an average bottom slope of around 17 ‰.

Catchment area

The Eckertsbach drains an approximately 6.3 km² area to the Murr, which extends about 5.5 km from the Höhenwald Forst northeast of Rietenau southwards to the mouth. Across from it, it is almost 2 km wide at the widest point in the local area of ​​northern Backnang. The with about 416  m above sea level. NHN highest point is at the northern tip in the forest above a mostly dry northern source brook blade; on both sides of the entire Pfaffenklinge there are still a few forest peaks over 370  m above sea level on the left and right . NHN , down from the forest outlet, the edge heights then remain consistently below 320  m above sea level. NHN .

In terms of nature , the area is divided into two parts. The north, roughly to where the closed forest breaks, is part of the southernmost Löwenstein Mountains , a sub-area of ​​the Swabian-Franconian forest mountains . The Backnanger Bay , a sub-area of ​​the Backnanger Bay, begins downwards . There, the fields in front of the meadows dominate the open corridor, there are also large areas with high-stem or espalier fruit meadows. The proportion of settlement with Strümpfelbach and above all a sector of the closed settlement area of ​​the central Backnang is also considerable.

Behind the eastern watershed, the Rohrbach drains successively from the northern tip of the catchment area to the Eulenberg-Sporn above the Eckertsbach to the Murr, then in its longer and flatter section this itself or its smaller right tributaries Froschbach, Dinkelbach and Kreuzhausbach drain the landscape. On the west side of the catchment area, the Forstbach over the Klöpferbach to the downward Murr, and then on the largest section of the Krähenbach, compete in the more mountainous northern part .

The northern catchment area down to the Großaspach – Strümpfelbach road is part of the Swabian-Franconian Forest Nature Park .

Localities

Politically, almost the entire area belongs to the city of Backnang and most of it belongs to the district of Strümpfelbach; on its west side there is a snippet on the edge that lies in the area of ​​the neighboring municipality of Aspach , in the far north one in the forest is part of the municipality of Oppenweiler . The only settlement areas in it all belong to Backnang: Katharinenhof Castle and Staigacker on the eastern watershed only partially, Strümpfelbach entirely on both sides of the central reaches, the hamlet of Seehof east of the beginning of Backnang on the left slope and finally with most of the settlement area a wedge of the town of Backnang itself, where the brook near Sulzbacher Straße soon turns underground.

geology

The highest geological layer in the catchment area is the silica sandstone ( Hassberge Formation ) of the southern Löwenstein Mountains, which covers its northern tip and extends southwards to the spur of the Eulenberg and the mountain spur opposite the lakes in the Pfaffenklinge in the Berghau in the west . On the Klingenhang, the lower colored marls ( Steigerwald Formation ) and the reed sandstone ( Stuttgart Formation ) spread out below . Farther to the south, on the south-facing hills on both sides of the not very deep valley basin Gipskeuper ( Grabfeld formation ) down to the settlement gap between Strümpfelbach and the northern edge of the central Backnang, wider on the left, eastern side of the valley than on the right. Below, in the valley basin after the lakes at the end of the Pfaffenklinge, on the hills there is loess derivative from Quaternary deposits, wider on the right with narrower gypsum keuper strips, probably because the loess was sedimented here in the lee of the dominant wind direction from the west. The Upper Muschelkalk only sets in superficially in the steeper valley where the buildings in Backnang also rise on the left slope. In this layer, the Bachtal finally creates its only half meander, after which the brook also flows into the Upper Muschelkalk.

The extensive subsidence structure of the Neckar-Jagst furrow with partly proven, partly only suspected fault lines runs through the upper catchment area from west-southwest to east-northeast in the area of ​​the Pfaffenklinge . Also further south in the catchment area, shorter disturbances aligned at an acute angle to this direction are suspected.

Near the Strümpfelbacher Weg in Backnang lies at an altitude of about 290  m above sea level. NHN and thus about 30 meters to the right above today's valley floor a largely built-up rock wall made of limestone from the Upper Muschelkalk, it is probably a former impact slope of the now deeper Eckertsbach; this shows that the loess derivative already covers the Upper Muschelkalk, which first appeared on the valley floor, at a higher elevation.
