The Maulach is a - depending on the source branch with which you want to start the stream - eleven to under twelve kilometers long stream in the area of ​​the city of Crailsheim in the district of Schwäbisch Hall in north-eastern Baden-Württemberg . It arises southwest of the hamlet of Maulach in the town in the high forest north of the Burgberg , which it leaves in a short run approximately northwards, and then in a long, low-slope and approximately southeastern run to the Jagst between Jagstheim and Ingersheim an der Jagst , into which it moves from the left something flows in after the Speltach .

geography

Upper Maulach

The upper course with the name Maulach arises in a long meadow bay in the Rennschlag forest in the northern Burgberg forest at about 449  m above sea level. NHN , about 800 meters south of the Crailsheim hamlet Ölhaus . In this the source stream runs northeast. Where the bay opens, it flows through the Bauernsee and then flows after about 0.9 km a little before the edge of the Burgbergwald forest at about 433  m above sea level. NHN with the longer right upper course together.

Upper course Buchklingenbach

The Buchklingenbach rises deeper in the forest about 1.1 km north-northeast of the Burgberg tower on a forest path star opposite a small pond at about 468  m above sea level. NHN , about a quarter of a kilometer west of an abandoned quarry. On the north run it runs through the initially narrow book blade . After the valley basin has widened , it runs through the three Buchklingen lakes one after the other in a clearing , and after another run in the forest it flows into the Maulach after 1.6 km before the forest . This source branch is not only longer, but also somewhat richer in catchment area than the Maulach up to the confluence and is therefore hydrologically the main upper reaches.

course

The Maulach now begins a small curve to the right over the flat floodplain and crosses under the Heilbronn – Crailsheim railway line . One kilometer further it takes you to 429  m above sea level. NHN on the Gaumannseebach between the railway line and the L 2218 accompanying it at a great distance , the first of only two northern tributaries from the Reußenberg area . From here it flows steadily in a wider floodplain to the south-east, only between the two traffic routes south past the hamlet of Maulach, after which the Schwarzlachenbach feeds the runoff of most of the lakes on the Reußenberg. Passing the village of Roßfeld a long way to the southwest , it changes to the other side of the railway line and then, close to the remains of the Flügelau moated castle, is fed from the west by the Herrenbach , its longest tributary, which arises a little north of the Burgbergkuppe.

It now touches the western edge of the industrial area Flügelau, there arises just a stone's throw to the left of it in the wide valley plain that runs parallel to it for one and a half kilometers , with which it later joins, and now flows a little further south towards Onolzheim . Until there, the Brenntenwasenbach and the Aspenbächle, their last two major tributaries, have flowed from the eastern edge of the Burgbergwald. In Onolzheim it is crossed by the L 1066 . At the end of the village, the long Mühlkanal branches off to the left to the Hammerschmiede , which after this runs back a good kilometer further downstream. From there it flows eastwards, crosses under the Obere Jagstbahn and flows between the Jakobsburg farmstead and the Stöckenhof after a short north run from the left and at 402.6  m above sea level. NHN in the upper Jagst .

The Maulach is 11.7 km long from the origin of the Buchklingenbach, 11.0 km from its own, of which about 9.1 km is accounted for by the section from a little before Maulach on which it runs to the southeast. The mean slope of the bottom corresponding to these running routes is between 6 and 5 ‰, around 4 ‰ and around 3 ‰.

Catchment area

The catchment area of ​​the Maulach is 24.9 km², it includes on the two upper reaches and also later on the right to the floodplain then the mostly wooded north-eastern edge of the lower natural area Burgberg-Vorhöhen and Speltachbucht of the Swabian-Franconian Forest Mountains , next to it in their foreland only a small portion in the Haller level and a large one in the Crailsheimer Bucht , both sub-areas of the neighboring natural area Hohenloher and Haller level .

Almost everywhere in the catchment area there is the Gipskeuper ( Grabfeld Formation ), which is only covered by the reed sandstone ( Stuttgart Formation ) on the Burgberg plateau and a nearby plateau . Due to embedded dolomitic, erosion-resistant layers, the gypsum keuper shows a stepped profile in many places on the edge of the Einkorn forest towards the shallow water basin. Below Onolzheim, a small area with Lettenkeuper ( Erfurt formation ) begins in the floodplain . For most of its course, the Maulach shows the south-eastern direction of flow of the old Danubian river system before the Rhenish river tapping and reversal.

One by one border the catchment area of ​​the Kirchberg- Lobenhausener Grundbach briefly in the north, then the Schmiedebach , the Lindenbach , the Sauerbrunnenbach and progressively smaller left tributaries upstream of the Jagst in the urban area of Crailsheim from north to east. The watershed runs from its southeasternmost foothill, Ehberg near Jagstheim , on the southeast side over the ridge of the Burgbergwald forest to a little northwest of the Burgberg itself and separates it from the larger drainage area of ​​the Speltach on the opposite side, which the Jagst meets shortly before the Maulach. Beyond the adjoining, very short western border, the Aalenbach arises , beyond the somewhat longer northwest border from the Burgbergwald to the Reußenberg, the Schmerach , both of which drain over the Bühler to the Kocher . The last-mentioned section of the total watershed is less noticeable in nature, the left one, which runs from Reußenberg to Onolzheimer Kreuzberg, typically 450– 455  m above sea level. Reaches NHN and then runs out quite flat, but mostly the right one, in the course of which the small high plateau on the top of the castle hill at 534.1  m above sea level. NHN towers highest at all.

The Maulach runs entirely within the boundaries of the city of Crailsheim. Only the neighboring community of Frankenhardt also has a share of the catchment area with only small fringes on the Burgberg heights .

Sights and buildings

  • The Burgbergwald, from which all the right tributaries to the Maulach originate, is a popular hiking area. A large part of the catchment area can be overlooked from the tower on the Burgberg .
  • North of the hamlet of Maulach lies the gypsum erosion landscape of the Reußenberg , a predominantly forested, very restless hilly landscape, characterized by swampy hollows and sinkholes filled with pools.
  • At the mouth of the Herrenbach, south of Roßfeld, lies the ruin of the Flügelau moated castle , easily recognizable from the terrain profile.
