The Harbach is a forest brook in the Murrhardt Forest in the Rems-Murr district in north-eastern Baden-Württemberg , which flows into the small town of Murrhardt from the right of the upper Murr after more than 6 km south of the hamlet of Harbach .
geography
course
The Harbach begins its fairly constant southern course on the still flat upper southern slope of the Hohen Brach , at 586.9 m above sea level. NHN highest mountain of the entire Swabian-Franconian forest mountains . Its origin is about a quarter of a kilometer south-southwest of the Großerlach hamlet of Hohebrach on the edge of its clearing island to the hillside forest at about 540 m above sea level. NHN on the municipal boundary of Sulzbach an der Murr , which follows its course for a long time. On its first one and a half kilometers, it digs up a steep slope, repeatedly taking up short and inconsistent tributaries from small secondary blades, down to below 450 m above sea level. NHN sounds into his forest before his first 0.8 km long tributary flows from the right ridge, which arises on the slope of the right ridge northeast of the Sulzbach hamlet of Eschenstruet. Shortly afterwards, for the first time, the open corridor extends from the left ridge around the Großerlach hamlet of Frankenweiler down to almost the bottom of the valley.
In the middle reaches in the area of the Waldgewanns Hölle, in a six-footed valley spider , the half-kilometer Steinbach from Zwerenberg on the right ridge and the slightly longer Rehbach from the left, which runs through its forest blade a good bit south of Frankenberg; the two are the first named tributaries. After the Rehbach, which is the border brook to the district of the small town Murrhardt , this replaces Großerlach as a left-hand neighbor. After the Harbach has flowed past the Murrhardter Höhenweilern Kieselhof, Hinter- and Vordermurrhärle on the left-hand side, it flows into the city limits and then, about one and a half kilometers from its mouth, enters the open corridor of its now noticeably widening valley funnel. Here it reaches the outskirts of the hamlet of Harbach and then flows between Harbach on the right bank and the hamlet of Gaisbühl on the left under the L 1066 , which accompanies the northwestern Murrlauf. Down from the roundabout of the state road, it crosses the right Murraue and then flows across from the Murrhardt sewage treatment plant at about 278 m above sea level. NHN from the right and, last but not least, northeast into the upper Murr .
No public road runs through or crosses the Harbach valley; There are mostly forest trails on the lower slopes.
Catchment area
The Harbach drains a 6.8 km², about 5.5 km long and nowhere more than 1.6 km wide strip between the 586.4 m above sea level. NHN- reaching summit of the Hohen Brach in the north and the confluence in the south with the upper Murr. In terms of natural space , it belongs to the Swabian-Franconian Forest Mountains , initially and largely to their sub-area Hinterer Mainhardter Wald , and finally to the sub-area Murrtal . The catchment area of the upper Fichtenberger Rot borders the highest northern watershed on the Brach, which runs south-east to the Kocher and drains over it to the Neckar , while beyond the other borders the drainage flows to this over the Murr . On the east side, the left competitor Trauzenbach runs to this, on the west side of the Haselbach , both roughly parallel to the south and at a distance of mostly less than two kilometers.
The landscape is dominated by the narrow valley cut of the creek, which is almost completely on the ground and on both flanks mostly forest, which is why the forest portion in the catchment area dominates. Its course follows on the two ridges in front of the neighboring valleys on the left and right winding high roads near the watersheds, which open up small agricultural settlement areas in clearing islands, which are connected in the west and separated in the east. Its parts on this side of the Scheiden are, besides the hamlet Hohebrach above the source, the only settlement areas in the area of the Upper and Middle Valley. The majority of the settlement areas of the hamlets Harbach and Gaisbühl are located in the estuary.
The brook arises in the transition area from the large Black Jurassic plateau, which lies on the Hohe Brach, to the upper and above all middle Keuper strata below. The Gipskeuper ( grave field formation ) is only reached from the creek bed about at the foot of the Kieselhof, after which the valley widens noticeably. It then still flows at the level of the Gipskeuper in the wide floodplain sediment band of the Murr. In the middle area, the Neckar-Jagst-Senke crosses the valley at the mentioned valley spider at Hell from west-south-west to east-north-east, a far-reaching subsidence zone from which a fault line has been proven on the north side. Where it runs over the eastern ridge in Feldgewann Hart , a small Black Jurassic island lies between the mountain hamlets of Frankenweiler and Kieselhof at an altitude of only about 510 m above sea level. NHN .
Tributaries
In addition to the two tributaries on the middle course listed here alone, at least another dozen or so periodic watercourses flow into the Harbach, all of which are less than a kilometer long.
- Steinbach , from the right and west to 384.7 m above sea level. NHN in hell , 0.5 km and approx. 0.2 km². Arises at almost 460 m above sea level. NHN north of Sulzbach-Zwerenberg.
- Rehbach , from the left and northeast to about 330 m above sea level. NHN in hell , 0.6 km and approx. 0.3 km². Arises at about 485 m above sea level. NHN on the western slope of the Hart between Großerlach-Frankenweiler in the north and the Murrhardter Kieselhof in the south.
natural reserve
A little north of the hamlet of Harbach, on the left lower slope between the brook and the lower edge of the forest, there is the 0.6 hectare nature reserve Harbacher Quellsumpf , a hillside spring moor in the Gipskeuper, which shows tuff formations.
