geography

course

The hamlet of Bach arises in the Limpurger Mountains not far from the forest path branching off from the coal road to Göbelsrain in Schenkengeren at about 495 m above sea level. NHN . In the forest between the mountain foothills of Göbelsrain to the east-northeast and Raitelsberg to the northeast, it runs in a right quarter arc to the valley, where it receives an inflow from a branched inflow system of forest streams and channels, and then changes after less than a kilometer at two fish ponds southwest of Weiler into the hallway. Then it flows northeast, first past the few farms of Weiler on the left slope. Down from it, its valley widens and it takes to about 395 m above sea level. NHN at the junction of another from the field path that now accompanies it, joins its only major underflow tributary from the left, the half-kilometer-long Kappelbach. It now draws fairly flat towards Unterfischach, crosses it at the waist of its settlement contour and then follows a field path that leads northeast to the Leippersberg above the opposite slope of the Fischach valley. Less than 200 meters after the outskirts, it joins a dirt road bridge from the right and south-east to just under 377.5 m above sea level. NHN in the lower Fischach .

On its 3.8 km long course, the hamlet of Bach does not lose quite 115 meters in height, its mean bed gradient is almost 30 ‰. After its near-natural upper course right in the forest, through which its sandy-gravelly stream bed winds, mostly deepened, the lower forest slope of the Göbelsrain continues to border on the section to the right near Weiler, here the stream is usually accompanied by a tree gallery Hamlet clears past. To the east of Weiler, the brook runs again briefly under the right leather heap next to a narrow strip of forest. Then in the flat lower reaches it runs on the side of a field path as an almost bare ditch, also crosses Unterfischach without any trees and then flows out as a straight ditch without galleries next to an asphalt field path.

Catchment area

The hamlet of Bach has a catchment area of 4.1 km². It extends roughly from the Kohlenstraße in its section between the Engelhofen – Sulzbach road and the former military depot in Haselbühl, about 3.7 km northeast to the confluence. Across it, it is a maximum of about 1.5 km wide. After the initial curve to the right, the stream runs quite centrally in it.

Beyond the northwestern and then northern watershed on the left Raitelsberg spur of the Limpurger Mountains, the Stielbach and its lower course Breitenbach run almost parallel to the Fischach . The southeastern watershed on the Göbelsrain- Bergsporn initially delimits the catchment area of the smaller and last significant Fischach tributary, the Schaufelbach , and further upwards, briefly, from that of the Kochklingenbach , which now drains via the Schleifseebach to the Fischach receiving waterway in the same way as the longer adjacent catchment area of the upper Klingenbach . At the southern tip of the drainage area, there is a short one from the Irsbach , which is near the origin of the hamlet, and then from its receiving water, the Eisbach , which the Limpurger Mountains run to the Kocher , which borders them on the opposite side .

The highest point is 511.5 m above sea level. NN on the southern edge in the collective forest just a little beyond the coal road on the rather flat plateau of the Limpurger mountains. As far as the middle reaches, the plateau falls on the narrower mountain spur Raitelsberg that accompanies it on the left to around 470 m above sea level. NN , on the wider right Göbelsrain ridge up to about 480 m above sea level. NN from.

Around half of the catchment area is forested, in the area of the plateau and on the slopes of Göbelsrain and Raitelsberg. The open corridor with the settlement areas belongs to the sub-area Fischachbucht and Randhöhen (No. 108.61), the mountainous forest part to the sub-area Limpurger Berge (No. 108.60) in the natural area Swabian-Franconian Forest Mountains (No. 108).

About 0.2 km² of the catchment area in the forest near the Göbelsrain ridge belong to the Geifertshofen district of the Bühlerzell community , the vast majority of the remainder to the Mittelfischach district of the Obersontheim community . This is where the only two settlement areas in the area are located, namely two hamlets, one with the proper name Weiler with a dozen house numbers on the left on the middle course and the larger Unterfischach with five dozen on both sides of the lower course on the edge of the Fischachaue.

Origin of the hamlet brook at about 495 m above sea level. NHN in Schenkengehren northeast near the coal road about 1.5 km southwest of Obersontheim- Weiler . Initially runs roughly north.

(Very symmetrical forest valley spider with left and right tributaries), from the west and east to about 440 m above sea level. NHN at the foot of the Schenkengeren , approx. 0.4 km and approx. 0.2 km². Arise at about 475 m above sea level. NN on the slope of the Göbelsrains and the Raitelsberg .
Passed at almost 430 m above sea level. NN immediately after entering the corridor, two ponds on the right, together 0.1 ha. At least one with a short slope spring inflow. From about here the stream runs northeast after a long bend in direction.
Passes a pond at almost 420 m above sea level. NN southwest of the hamlet , 0.2 ha.
Kappelbach, from the left and west to about 395 m above sea level. NN between Weiler and Unterfischach , 0.8 km and approx. 0.5 km². Arises at about 425 m above sea level. NN on a dirt road. which branches off a little north of Weiler to the east of the access road K 2623 from Engelhofen . Ditch along the whole length.
(Inconsistent ditch), from the left and west to about 389 m above sea level. NN less than 200 meters from the outskirts of Unterfischach , approx. 0.8 km and approx. 0.2 km². Arises at about 420 m above sea level. NN little next to the K 2622 Engelhofen – Unterfischach.

Mouth of the hamlet brook from the right and south-west to 381.5 m above sea level. NHN next to the bridge of the field path from Obersontheim - Unterfischach to Leippersberg from the right and southwest into the lower Fischach . The stream here is 3.8 km long and has a catchment area of 3.9 km² behind it.

geology

The hamlet of Bach runs in Keuper . The uppermost spring arises just below the layer boundary between the Stubensandstein ( Löwenstein Formation ) and the Upper Bunte Marln ( Mainhardt Formation ) below . Then it passes through the silica sandstone ( Hassberge Formation ), in which the nearby secondary sources arise. In the following transition area to the lower colored marls ( Steigerwald formation ), small sintered limestone surfaces have formed, in the lower colored marls the small upper courses collect. The reed sandstone band ( Stuttgart formation ) crossed in the following is not very wide, after which the stream enters the gypsum keuper ( grave field formation ) about 800 meters down from its top source near the edge of the forest , in which it will remain until the mouth . On the first section it runs in the only gently sloping layers of estheria of the Gipskeuper to near Weiler, after which the gradient increases again briefly past the settlement area. In the further gypsum keuper, the floodplain sediment band of the hamlet brook expands significantly before, after crossing Unterfischach, it joins the Fischach .

Above all to the left of the eastern slope of the Raitelsberg , the estheria layers of the gypsum keuper spread out over a large area. On the spur in front of the Breitenbach , which continues to the north-east , the erosion-resistant Corbula layers of the gypsum keuper have leveled at 420 m above sea level. NHN and a little below that, which extends on a spur finger up to about 200 meters from the Unterfischach border.
