The Echtbach , together with its longer upper course, is over 3 km long in the Schwäbisch Hall district in northern Baden-Württemberg . It arises itself at the western foot of the forest area around the Neuberg castle ruins , in which its two upper courses arise. After a little less than 2 km west-southwest of its own course, it flows into the lower Aalenbach from the left in Talheim in the small town of Vellberg .

geography

The origin of the Echtbach itself is at about 382  m above sea level. NHN less than 200 meters south of the Hilpert farm in Vellberg . There, at the already open foot of the mountain forest around the Höhensporn Neuberg, the somewhat longer right upper course Hilpertsklingenbach, coming from the northeast, and the somewhat shorter, but somewhat more catchable, left upper course Seebach, come together from the east . Both upper courses arise in forest blades typical of the landscape , have a noticeably steeper gradient than the common lower course, are often dry at the top around summer and also have low flow rates further downwards.

Hilpertsklingenbach

The Hilpertsklingenbach rises up to about 472  m above sea level. NHN near the Steigenkopf of the K 2665 from Vellberg- Großaltdorf to Frankenhardt - Steinehaig in a steeply incised blade crack. Between the mountain forest Rosswart on the accompanying height on the right and the Bergsporn Neuberg on the left it flows southwest, reaches the edge of the corridor near Hilpert and then unites with the Seebach.

The Hilpertsklingenbach is 1.4 km long, falls on this route by about 90 meters and has a mean bottom gradient of about 65 ‰.

Seebach

The Seebach rises lower at about 445  m above sea level. NHN in Waldgewann Hengstnest between the slope of the cul-de-sac on the Neubergsporn in the north and the Hackenberg in the south. It flows roughly westwards, runs halfway through a small forest pond under the Frankenhardt residential area Neuberg on the spur of the same name. After a short walk through the Seewiesen corridor , it unites with the Hilpertsklingenbach to form the Echtbach.

The Seebach is 1.2 km long, falls on this route by about 63 meters and has an average bed gradient of about 51 ‰.

course

The at about 382  m above sea level. The Echtbach river, which originated from the NHN , flows approximately in the direction of the west-south-west through its valley to the left of the last tip of the wooded Hackenberg, to the right of the Rosswart , which is wooded down to the foot of the mountain and whose floodplain is largely occupied by fields. There are mostly tree galleries and field hedges near the shore. After a good 200 meters, the only major tributary flows out of the Brunnenklinge from the right and finally north-west, which drains a large part of the northern, widely wooded catchment area; In the lower corner of the mouth there is a sinkhole which, after heavy rains, damms the water into a more or less wide pool. After this stream flow from the fountain blade of the well wooded at the top Hackenberg in its deeper spur spurs left comes at the height Schlegelsberg over whose little incident plateau above the steep hillside forests including stands Upturned, while on the right the real Bach of limiting on the west side of the fountain blade Binselberg only a little later moves towards the stream. Old orchards run down the slope under the upper bend of the Binselberg, marked by a field hedge. On the lower slope of the Binselberg, the first houses from Talheim am Sträßchen von Hilpert will soon be built. Only late, however, does the brook, which now runs in a deep basin, enter the development contour of Talheim, where it also largely flows openly. It crosses under the L 1040 Großaltdorf – Vellberg and then flows behind the courtyard property on the other side of the road at 342.5  m above sea level. NHN from the left in the lower eels , of which it is the last and largest tributary.

The Echtbach, which is 1.8 km long on its name run, falls by around 40 meters in altitude on this route, its mean bottom gradient is around 22 ‰. If you add the longer right upper reaches of the Hilpertsklingenbach, then the brook is 3.2 km long, flows about 130 meters below its source and has an average bed gradient of about 41 ‰.

Catchment area

The Echtbach has a 3.9 km² catchment area. From a natural perspective, it is located with its higher and middle proportions mainly in the lower area of ​​the Burgberg Vorhöhen and Speltach Bay of the Swabian-Franconian Forest Mountains and only with the Untertal and just under one sixth of the area in the sub-area of Vellberger Bucht of the Hohenloher and Haller levels . It is a feathered erosion bay of the Keuperbergland , which is framed and structured by spurs and mountains.

The northwestern watershed climbs the Binselberg near the mouth of Talheim , which is far to the north at about 455  m above sea level. NHN Höhe merges into the Streich forest , which slopes northwards to the higher Aalenbachtal near Kleinaltdorf ; the runoff on the other side is taken up by the Aalenbach , which drains via the Bühler to the Kocher, via its left tributaries, of which only the unstable Vogelsbach that arises in the Streich forest is worth mentioning. Behind the subsequent short piece of northeastern watershed over the local with about 483  m above sea level. NHN's highest point in the Rosswart forest is the path of the K 2665 Großaltdorf – Steinehaig in the catchment area of ​​the Steppach , the other large left Aalenbach tributary.

At the Steigenkopf, the catchment area boundary reaches the district road close to the origin of the Hilpertsklingenbach and, based on its route, winds southwards until it finally reaches 511.6  m above sea level. NHN high Hackenberg , whose summit on the southeast corner is the highest point of the catchment area; east of this hydrologically most important section, the Seebach drains to the Buchbach and the Buchbach itself to the Speltach , a tributary of the Jagst .

The west-south-west long drawn-out Hackenberg and its deeper spur foothills Schlegelsberg (down to about 425  m above sea level at the water reservoir on the foremost spur) follows in the opposite neighboring valley roughly parallel to the Lanzenbach , now again a tributary of the Bühler, which itself on most of the spur tip is the closest permanent water body beyond the catchment area boundary.

The largest part of the catchment area is forest, less than a third of it is open, mostly it is the valley basin at the confluence of the upper courses, plus only short and one-sided lower valley sections of the upper courses as well as narrow ridges on Binselberg and Schlegelsberg and a very small clearing the Neuberg

About one-sixth of the catchment area belongs to the Oberspeltach submarket of the municipality of Frankenhardt , essentially unpopulated forest area on the Neuberg-Sporn and on its slopes as well as parts of the lower rear Hackenberg-slope. The Neuberg detached house is the only settlement that is now uninhabited in the front on the spur of the same name next to the Neuberg castle ruins . The rest of the catchment area is in the urban area of Vellberg , including the inhabited individual Hilpert estate near the foot of the Neuberg and part of the Talheim estuary .

NHN in the forest on the upper Schlegelsberg slope and flows, initially unsteadily, initially northeast to north to near the ice path. A right branch of the upper course rises at about the same height about 0.5 km further north-east next to the rise of the ice path up to the Schlegelsberg a layered spring .

Mouth of the Echtbach from the left and east-northeast to 342.5  m above sea level. NHN on the southwest edge of the old town center of Vellberg - Talheim in the lowest Aalenbach . The Echtbach and its upper reaches, the Hilpertsklingenbach, are 3.2 km long, on the course with its name from its confluence with the Seebach it is 1.8 km long and has a 3.9 km² catchment area.

geology

The two upper reaches Hilpertsklingenbach and Seebach as well as the only large tributary from the Brunnenklinge all arise in the Gipskeuper ( Grabfeld Formation ) directly or slightly below the reed sandstone border ( Stuttgart Formation ). Only at about the inflow of the last does the Echtbach change into the Lettenkeuper ( Erfurt formation ), in which it remains up to the mouth. The mountains bordering the catchment area and the inner spurs Neuberg between Seebach and Hilpertsklingenbach and Rosswart between this and the Brunnenklinge are predominantly leveled areas in the reed sandstone; Only the Hackenberg on the southeastern watershed to the Lanzenbach rises over the upper slopes in the Upper Bunter Marls ( Mainhardt Formation ) to a narrow, but again flat plateau in the silica sandstone ( Hassberge Formation ), while on the northwestern watershed the flat one Slope southwest of Talheim, the narrow plateau spur of the Binselberg soon no longer has reed sandstone cover.

There are two geotopes in the Gipskeuper, a sinkhole on the right side of the brook from the Brunnenklinge shortly after its exit from the forest, about 8-10 m wide and overgrown with wood, and a chain of sinkholes on the left above the lower Echtbach on the wooded and steep upper left slope of the Schlegelsberg . Some other sinkholes in the catchment area are not designated as geotopes. The most striking of these is probably one in the lower corner of the mouth of the stream from the fountain blade, which is covered by a fairly wide puddle of water after heavy rainfall.

In the northern catchment area, anhydrite and gypsum are mined in the Kreuzhalde anhydrite mine. The mine access tunnel is located on the Kreuzhalde on the left slope of the Aalenbach valley and leads into the Sporn Binselberg. The area of ​​the concession, which is partly being dismantled and partly open, is located, for the most part, within the catchment area, under the Binselberg, the Streich, the Rosswart and the Neuberg.

Nature and protected areas

The foremost onere Schlegelsberg above Talheim: belongs to the Bühlertal nature reserve between Vellberg and Geislingen with side valleys and adjacent areas . There are a few natural monuments in the catchment area, namely the under →  Geologist mentioned covered sinkhole next to the wood exit of the stream from the fountain blade, a Dolinenkette in the forest of Schlegel mountainside between the two spring arms of the stream from the Heiligenwiesen , a lean grass at the edge of the settlement of Talheim Schlegel mountainside and the Talheimer Eiche at the junction of the ice path from the Talheim – Hilpert road.
