geography

Source and history

The Mühlbach flows about 450 m southwest of the town center of Grab at about 491  m above sea level. NN under the name Götzenbrunnenbächle a small pond in the flour mowing . From here it moves the first hundred meters of its long eastern course through a small northern corner of the forest to the east. Then it leaves the forest and then flows for almost a kilometer through an almost woodless meadow in the same direction, between the Gewannen Heide in the north and Einschlag in the south. At the entrance to the forest between Morbach in the south and Schönbronn in the north, it reaches the southern edge of the Schweinetanne forest , then turns to the northeast and digs a forest blade .

After another 0.6 km it reaches it in the eastern Schweinetanne from the left and at 429.6  m above sea level. NN the Schweinetannbach , whereupon it becomes the Aschenbach and moves on in the direction of its tributary in its forest valley about one kilometer to the southeast. Then he steps out of the forest into the open meadow and from the right reaches him at 402.4  m above sea level. NN the Morbach . Immediately afterwards, the approximately 0.2 km long Mühlkanal branches off to the left to the Marhördter Mühle, which feeds two ponds with a total of approximately 0.1 hectares before it reaches it  . From here on it's called Mühlbach .

After passing the mill and running for another 0.3 km, the K 2674 from the direction of Marhördt crosses it from the left, which accompanies it in the rest of the way up to its mouth. At 383  m above sea level NN opens out again about the same flow path from the right was the 1.9 km long Heidebach , then rich on a short piece of the forest slopes on both sides again down to the shore. After the reopening of the floodplain, the 0.3 km long Mühlkanal branches off to the left to the Marhördter Säg mill and a 0.7 km long blade tributary through the Bronnklinge down from Konhalden flows into the stream itself from the right.

The Mühlbach flows after the Marhördter Sägmühle between the almost adjoining Lower Kornberger Sägmühle and Badhaus and then flows out at 367.9  m above sea level. NN after 4.9 km run from right in the Fichtenberger red .

Tributaries

List of source branches and tributaries, also of a higher order, each indented below the superordinate body of water, as well as the RiverIcon-SmallLake.svglakes through which it flows . Line up from the source to the mouth. Raised from LUBW-FG10 / LUBW-SG10 and TK25. Where possible and sensible, with name, mouth side, mouth location and length. Water courses, lengths and areas preferably according to LUBW, names preferably according to TK25. Lengths to a full hundred meters, areas rounded to a tenth of a hectare. Water body names in italics are used as proper names in one of the sources used, otherwise a descriptive name is used as a substitute, of which only the italicized parts (valley names, mountain names, common names, etc.) are proper names from the sources.

The official origin of the Mühlbach according to LUBW-FG10 is that of the Götzenbrunnenbach

  • Götzenbrunnenbächle , right source branch, approx. 1.6 km. Arises approx. 400 m southeast of the center of Grab at the edge of the forest as the outflow of a RiverIcon-SmallLake.svgpond of less than 0.1 ha in the flour mowing .
  • Schweintannebach , left source branch, 1.0 km. From the confluence, the stream is called Aschenbach for the next approx. 1.0 km .
    • (Inflow from the northern edge of the Beckenwäldles ), from the left in the Schweinetanne , approx. 0.3 km.
    • (Inflow from the golf course), from the left in the Schweinetanne , approx. 0.4 km.
  • Morbach , from the right west of the Marhördter Mühle, 1.9 km. Develops a little south of Morbach. From here the stream bears the name Mühlbach .
    • (Inflow from the slope of the Butzberg ), from the right on the K 1809 Morbach – Marbächle, 0.1 km.
    • (Inflow from the Baier down), from the right, 0.4 km.

    • (Inflow from the edge of Platte), from the left, 0.2 km.
    • (Mühlkanal from the Heidenbach ), from the right a few steps before the confluence of the Morbach and Aschenbach , 1.3 km. Only after LUBW-FG10, the TK25 does not know this channel.
      • (Inflow through the Wolfsklinge down the Morbachhalde ), from the right 0.1 km before the canal confluence with the Morbach , 0.2 km. The TK25 lets it flow its last 0.1 km from there 0.3 km over the LUBW-FG10 common section of the otherwise missing canal into the Morbach .
  • (Exit of a canal), to the left to Marhördter Mühle, municipality of Oberrot, approx. 0.2 km, which successively crosses two ponds of approx. 0.1 ha. No obvious backflow.RiverIcon-SmallLake.svgRiverIcon-SmallLake.svg
  • (Inflow from the direction of Marhördt), from the left in the area of ​​the Marhördter Mühle or shortly afterwards, at least 0.7 km. The watercourse is the outflow of a RiverIcon-SmallLake.svgpond in Marhördt of less than 0.1 ha in size.
  • Heidenbach through the Heidenklinge , in the upper reaches of and around the municipality of Großerlach Forchenbächle , from the right at the junction to Marbächle from Talstraße K 2674 at 383  m above sea level. NN , 2.3 km. Arises on the eastern Mannenweiler plateau.
    • Immediately flows through a RiverIcon-SmallLake.svgpond of less than 0.1 ha on the border of the plateau to the hillside forest.
    • Forchenbächle, from the right in the direction of the valley axis below, 0.3 km. The unified brook is initially also called Forchenbächle .
    • (Exit of a mill canal) - but only after LUBW-FG10 - to the left to just under 430  m above sea level. NN , 1.3 km long. The canal initially runs with a slight gradient on the left Heidenbach slope, then bends around its mouth and then flows against the Mühlbach direction to the last right tributary of the Morbach , which it is at just 410  m above sea level. NN takes up to then flow into the Morbach . See also there. The TK25 does not show this canal run.
  • RiverIcon-SmallLake.svg Flows through a pond under 0.1 ha.
  • Exit of the Mühlkanal to Marhördter Sägmühle, to the left, 0.3 km.
  • (Bach from the Bronnklinge ), from the right just before the Marhördter Sägmühle across from its Mühlkanal in the Mühlbach itself, 0.8 km.

Mouth of the Mühlbach after a total of 4.9 km run - calculated from the confluence of the upper reaches of the Aschenbach and Morbach it is only about 2.1 km - and at 367.9  m above sea level. NN at the Lower Kornberger Sägmühle of the municipality of Oberrot from right into the Rot .

Half a dozen ponds with a total area of ​​almost 1 hectare are located on the Marhördt golf course with a partially plausible but not obvious flow direction on the map sources.

Catchment area

The Mühlbach has a catchment area of ​​8.2 km². The western tip of it is on the southwestern outskirts of Grab. The border runs from here roughly on the route of the Sulzbacher Straße through the village to the northeast and further to a little south of Schönbronn; on the other side the Schöntaler Bach drains to the Fichtenberger Rot . From there the border continues east-northeast along the route of the Alte Straße to the Dicken Wald ; here in the north the short red tributary Katzenbach competes first , then above all the nearby Rot itself. In the thick forest the watershed bends to the southeast and then runs northeast past Marhördt through the hamlet of Ofenberg and over the mountain spur of the same name down and through the terrain the Lower Kornberger Sägmühle to the confluence with the Rot ; on this section, too, the nearby Rot itself - after its south bend at Wielandsweiler - is the immediate competitor.

From the estuary, the catchment area border runs southwest through Badhaus and then up the eastern Konhalden , on the first step behind it on the outside of the hamlet of the same name and then up the spur of the Buhl . At the top she keeps to the forest road from Konhalden in the direction of Wolfenbrück and then climbs a small hump in the Buchreute immediately north of the Wolfenbrücker Steinbühl ; here on the other side only a short slope stream flows southeast of Badhaus and then the long Maßlesbach to the Rot, called Heiligenbach in the upper reaches .

The area beyond the watershed in the south to the west drains into the Trauzenbach flowing to the Murr . On the first, westward piece of the catchment area border to the south of the Mannenweiler Liasplatte, only the Trauzenbach tributary Siegelsbach is the opposite competitor. Just south of the hamlet the watershed bends to the northwest, runs through the west of Mannenweiler and sharply in the south of the Schweizerhof up to the Hohbühl and then over the Heidenbuckel to the southwest outskirts of Grab. It touches the catchment area of ​​the Katzenbach up to the Hohbühl , behind it up to the Heidenbuckel of the Fröschlochbach and on the last part that of the uppermost Trauzenbach itself.

The catchment area of ​​the Mühlbach consists roughly of half of the forest and the other half of the open corridor, in which the green corridor dominates. There is a golf course between Schönbronn and Marhördt. Smaller arable areas are on plateaus at 480– 520  m above sea level. NN east of Grab, around Morbach, Marbächle and Marhördt and on the Liasplatte from Mannenweiler up to almost 540  m above sea level. NN .

Localities

The Mühlbach rises in the community of Großerlach ( Rems-Murr district ) and flows into the community of Oberrot ( district of Schwäbisch Hall ). The slightly larger western part of the catchment area belongs to Großerlach, the eastern part to Oberrot.

The largest settlement in the catchment area is the southeast part of the village of Grab; in addition, the hamlets of Mannenweiler and Morbach as well as the residential areas Schweizerhof, Butzbach and Platte belong to Großerlach. The hamlets of Marhördt, Marbächle, Konhalden and the residential area of ​​Ofenberg belong to Oberrot. All of the above are located on plateaus, on the stream and in the valley, on the other hand, only the Oberroter Höfe Marhördter Mühle and Untere Kornberger Sägmühle and its settlement areas Marhördter Sägmühle and Badhaus.

Grab, the Untere Kornberger Sägmühle, the Badhaus and Mannenweiler are on the watershed, the Schweizerhof close by. For the respective other direction of drainage see under catchment area .

geology

The course of the Mühlbach and most of its larger tributaries begins and ends in the Mittelkeuper, the Heiligenbach- Oberlauf Forchenbächle arises above it in the Lias.

The southern part of the Mühlbach catchment area is criss-crossed by a number of geological faults in the Neckar-Jagst furrow system , which run parallel to this basin line to the east-northeast, but also east-southeast. Their deep clods are located in the south, which is why there are extensive marl ( Trossingen formation ) on the dominant Stubensandstein ( Löwenstein Formation ) and even lower Jurassic layers in two isolated plateaus around Mannenweiler and southwest of Konhalden .

On both sides of the Mühlenbach valley, roughly from the entrance to the forest of the uppermost Götzenbrunnenbächles , there are deeper layers of the Mittelkeuper down to the Gipskeuper ( grave field formation ) near the mouth. To the left of its south-south-eastern valley from the Aschenbach , around Marhördt and on the spur of the Ofenberg, there is a leveling area in the silica sandstone ( Hassberge Formation ), further north in the Thick Wald there are large areas of Obere Bunte Marl ( Mainhardt Formation ). Sliding masses shifted in association occur below the Lias surfaces and on the left slope of the valley below the Marhördter Mühle.

Landscape and nature

Landscape image

About half of the catchment area of ​​the Mühlbach is made up of forest, the other half is a sparsely populated open field in which the grassland dominates. It is cut by the middle and lower blade valleys of the watercourses in corridor islands on plateaus, which mostly only partially drain to the Mühlbach: In the northeast, on the spur between Mühlbach and Rottal lies the Marhördt clearing island between Ofenberg and Marhördt; in the northwest the Schönbronn, in the west the Graber and in the southwest the Morbach clearing island, which have grown together into one; in the south the small Mannenweiler and north-east of it the similarly large Marbächler clearing island and further east the one around Konhalden. The Schweizerhof is located near Hohbühl on the watershed in a small snippet of this side of the island around the Murrhardter Gutmachhof.

These plateaus at mostly over 480  m above sea level. Most of the NN allow arable farming only to a limited extent due to unsuitable soils, unlike the Lias area around Mannenweiler, which is almost 540  m above sea level. NN reached. The forest, which also fills the upper valleys, usually begins at the edge of the valley. The Mühlbach only has an open floodplain again from the Marhördter Mühle to the mouth of the Heidenbach , which finally also flows at the edge of the meadow, and then again in its mouth into the Rot.

In the eastern tip of the Schönbronn Flurinsel begins a 57 hectare golf course, which stretches from here south-southeast past Marhördt to Ofenberg on the tip of the spur between Mühlbach - and Rottal .

Protected areas

The valley and catchment area of ​​the Mühlbach are part of the Swabian-Franconian Forest Nature Park . To the southwest of the road from Grab to Morbach, an edge of the catchment area belongs to the Trauzenbachtal conservation area . The nature reserve Fichtenberger Rot-, Murr- and Fornsbachtal with adjacent mountain ranges includes the valley of the Mühlbach in the narrower sense, the lower valley of the Aschenbach half way up to the confluence of Götzenbrunnenbächle and Schweintannebach as well as the valley section of the Heidenbach downstream of the Marbächle-Konhalden road.

Half a dozen trees around the church in Grab are protected as a natural monument, as well as an oak tree at the edge of the Götzenbrunnenbächles forest and another, which is very lost on the woodless meadow that follows.

On the Alte Straße east of Schönbronn there is a structure-rich forest edge under biotope protection . The floodplains of Götzenbrunnenbächle, Aschenbach, Morbach, Heidenbach and a stream from Marhördt that are not shown on the maps are protected as biotopes. In the open country, too, a large part of the biotopes classified in this way is located in the vicinity of the watercourses, which include several spring areas, wet meadows, litter meadows and the like. In addition, many field trees and hedges are under protection in the corridor.
