The Aalenbach , called Äulesbach in the lower reaches , is a 9.6 km long body of water in north-eastern Baden-Württemberg , which flows into the Bühler from the right not far from Vellberg- Valleyheim .

geography

Origin and course

The Aalenbach rises in the tip, which the Burgbergwald extends northwest towards Ilshofen - Eckartshausen , at about 450  m above sea level. NHN in a blade a few steps south of the intersection of the forest path from Ilshofen-Eckartshausen to Burgberg with the forest path from Crailsheim -Ölhaus to Vellberg - Lorenzenzimmern . The slightly larger neighboring waters of Schmerach (to Bühler) and Maulach (to Jagst ) also arise in the Burgbergwald, not a kilometer northwest or southeast of this point . From its source the brook runs in a south-westerly direction, which it largely maintains until its mouth.

After a distance of about 700 m and a slope of about 30 m, the brook emerges from its forest edge and into a wide and flat bay, then takes the slightly longer brook from the badger's blade from the left and then passes the gypsum open pit in Gänswasen on its right slope , with another inlet from the Devil's Blade probably with the name Ackersbach reaching him from the left . A little later it crosses the hamlet of Vellberg- Lorenzenzimmern in an almost imperceptible hollow , in which it also cuts the L 1040 Oberschmerach-Vellberg, shortly afterwards a short ditch leads to it from the right, then the Brühlbach from the left . Its valley basin is now more pronounced, it takes up the Emersbach and the Razenbach one after the other from the right , then the Zimmerbach from the left .

On its right slope there are already the first houses of the village Vellberg- Großaltdorf , which has grown together with the adjoining Vellberg- Kleinaltdorf , their common southwestern settlement boundary follows the brook for almost 2 km halfway above the valley basin. This first crosses under the L 1040 again, then takes on the Steppach from the left , its longest tributary on the upper reaches, and finally the K 2665 from Spaichbühl reaches Kleinaltdorf on a road embankment across the valley basin. After the local border, the Vogelsbach soon flow in from the left and the Mühlenbach from the right, and then a little further down the valley from the right the Breitfeldgraben ', which borders the Vellberg industrial area on the upper reaches.

While it flowed on its route in the corridor until now, largely straightened, sloped in and holding the center of its hollow, it now begins to lay in narrow meadow meanders. In this way, crossing under the L 1040 again, it reaches the Vellberg suburb of Talheim, where its longest tributary ever reaches it from the left, the Echtbach . It still passes to the right at the foot of the Talheimer Siedlung and then turns abruptly for the last 300 m of its course to the west, then to about 334  m above sea level. NHN flow into the Bühler from the right. To his left on this last section is the small mountain of the Vellberger Stöckenburg with the mountain hamlet of the same name.

Between the source blade exit of the Aalenbach and Kleinaltdorf, at best, sparse bank trees accompany the stream. The valley is sparsely populated and characterized by agricultural use.

Catchment area

The catchment area of ​​the Aalenbach covers 19.2 km² and, from a natural point of view, lies in the transition area from the Swabian-Franconian forest mountains to the Hohenlohe and Haller levels . The source blade of the water and the blades of the left inlets, including some parts of their erosion bays, are located in the lower area of ​​the Burgberg Vorhöhen and Speltach Bay , where the higher heights are also, including the one at 511.6  m above sea level. NHN highest point on the southeast corner on the Hackenberg . The larger remaining part of the area in the northwest, with almost the entire course, is in the Hohenloher and Haller level, up to between Kleinaltdorf and the industrial area Talheim-Kleinaltdorf in the sub-area of ​​the Haller level upstream of the mountainous area , then - because the Aalenbach is at an obtuse angle to the Bühler runs - in the lower area Vellberger Bucht , the exit bay of the Bühler from the Swabian-Franconian forest mountains.

In the north-west and north the catchment area borders on that of the Schmerach , in the north-east briefly on that of the Maulach , in the east the Speltach competes , in the south the ( Schneckenweiler ) Lanzenbach, which flows into the Bühler at Vellberg- Eschenau . To the west of the watershed, some rather short bodies of water strive straight to the Bühler, especially the Binsenwiesenbach and the stream through the Kappisklinge .

The Aalenbach is a step edge water that runs close to the north-western edge of the Burgbergwald . It therefore receives most of its inflow from the left, above all from three relatively long tributaries (brook through the Teufelsklinge / Ackersbach, Steppach , Echtbach ) that have dug wide bays or steep blades into the adjacent highlands. The Steppach taps more and more of the ( Frankenhardt -Bonolzhofer) Seebach from above , a branch of the right upper reaches of the Buchbach of the Speltach. From the northern slope of the Hackenberg down to the southern Echtbach-Oberlauf Seebach slope parts slide from time to time; The severe erosion on the northern Echtbach-Oberlauf Hilpertsklingenbach is easy to see from a forest road on the upper right-hand side of the Klingenhang.

Parishes and places

After the first half a kilometer in the forest, which is in the Crailsheim district, the Aalenbach only runs on the Vellberger district. Frankenhardt still has a small share of the catchment area east of Vellberg-Talheim, with the mountain and forester's house Neuberg ; to Ilshofen include insignificant gusset in the west and northwest.

The following towns in the small town of Vellberg are located directly on the run :

geology

The Aalenbach rises in the Gipskeuper ( Grabfeld Formation ) of the Burgbergwald forest and then from around Vellberg- Lorenzenzimmern for the most part in the Lettenkeuper ( Erfurt Formation ). At Kleinaltdorf, the stream bed cuts into the Upper Muschelkalk over a distance of about one kilometer . At the bend shortly before its mouth, the Vellberger Fault crosses it , where it finally changes to the Upper Muschelkalk.

Above the immediate valley basin on the left side and on the elevation to the Keuperbergland of the Burgbergwald forest there is predominantly Gipsleuper, in some elevations it is still covered by reed sandstone ( Stuttgart formation ) and on the south-east corner even over a slope of lower colored marls ( Steigerwald formation a Small layer island of silica sandstone ( Hassberge Formation ). The lower slopes on the right-hand side reach the Hipsleuper after the blade exit of the stream, which in turn is largely covered with loess sediment from Quaternary deposits between Lirenzenzimmern and Vellberg .

On the slopes or the mountains on the edge of the Aalenbach there are several places where gypsum was or is still being mined: To the east of Lorenzenzimmern on the right foot of the slope in the "Gänswasen" is a smaller, active break. To the northwest of Lorenzenzimmern lies an abandoned gypsum quarry, which is now a shrubbery nature reserve. Between Großaltdorf and Talheim, west of the valley on the west side of the Äulesberg-Kuppe, there is an open-cast mine that can be seen from afar; anhydrite is mined from a tunnel at the Kreuzhalde on the left side of the valley .

In the local area of ​​Talheim, a now enclosed, short tributary of the Echtbach follows the little road from Hilpert, it rises in the border area of ​​Gipskeuper and Lettenkeuper and has created a longer lime sinter bank there .
