The Seebach is the left upper course of the Echtbach in the Schwäbisch Hall district in northern Baden-Württemberg, just over a kilometer long . It arises in the forest area around the Neuberg castle ruins on the edge of the municipality of Frankenhardt and, after running approximately westward, near the individual farm Hilpert in the small town of Vellberg, merges from the right with the right Hilpertsklingenbach .

geography

The Seebach arises at about 445  m above sea level. NHN in Waldgewann Hengstnest below the loop of a gravel path from the K 2665, which then merges into an earth path on the lower slope of the Hackenberg . It flows westward with little change of direction. About halfway through its run, it runs through at about 404  m above sea level. NHN has a pond with a size of less than 0.2 hectares, dammed behind a dam with a farm road on the Krone, above which the now uninhabited house of the Frankenhardt residential area Neuberg stands close to the Neuberg castle ruins on the right height above the forest slope on the Neuberg- Sporn . From the lake on the right on the lower slope, a farm road accompanies the stream. A short channel from a slope notch runs from the left immediately after the dam, a little afterwards from the same side a 0.6 km long Hangklingenbach, which at about 480  m above sea level. NHN rises from a source on the upper Hackenberg slope; Around the year 2010, in a late winter, its lower brook notch was buried in sections with slipped soil down to the Seebach, which was dammed up one to two meters high. Soon afterwards, the Seebach changes from the forest to the Seewiesen corridor . Finally it flows to about 382  m above sea level. NHN together with the Hilpertsklingenbach to 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 ‰. It is up to 1.5 m wide and has little flow, its bed is sandy to muddy and covered by fine-grain rock gravel, in places seepage springs in the forest on the lower slope have created small cushions of limestone sinter . Sections of the course of the brook indicate that it was straightened earlier, but the brook has now broken out again, swinging. On its last stretch in the open corridor of the Seewiesen , the slightly winding stream, about a meter wide, is partly accompanied by a gallery of alders and willows.

Catchment area

The Seebach has a catchment area of ​​around 0.9 km². From a natural perspective, it is located in the lower area of ​​the Burgberg Vorhöhen and Speltach Bay of the Swabian-Franconian Forest Mountains . The highest point is on the southeast corner at up to 511.6  m above sea level. NHN reaching flat plateau of the Hackenberg .

The area is almost entirely covered with forest, the less than a tenth of the open area is near the mouth of the lake meadows and mainly on the left on the lower slope above this and to a lesser extent as a narrow strip on the right on the plateau of the Neuberg spur.

The catchment areas of the following neighboring waters border in turn:

  • In the north, beyond the Neuberg spur, lies the blade of the other Echtbach upper course, Hilpertsklingenbach ;
  • then in the north and in the east another Seebach takes up the outflow of the shallower sloping slope to the other side, which flows into the Buchbach ;
  • on the south-east side, the Buchbach itself, which arises on the eastern slope of the Hackenberg, competes against the right upper reaches of the Jagst- tributary Speltach ;
  • Behind the long southern watershed on the narrow Hackenberg plateau, the Lanzenbach , which takes in only small tributaries from the right, flows westwards to the Bühler , which then also takes in the Aalenbach stream receiving water further down .

A little over half of the area of ​​the catchment area in the north-east with the Neuberg-Sporn and most of the Hackenberg-Slope on the other side of the upper reaches lies in the municipality of Frankenhardt ; This also includes the Neuberg residential area on the mountain spur of the same name , which is uninhabited today (2020) . The remaining part without any settlement and with only the lower reaches of the Seebach belongs to the urban area of Vellberg .

  • RiverIcon-SmallLake.svgFlows through at about 404  m above sea level. NHN a reservoir, under 0.2 ha.
  • (Bach vom Hackenberg ), from the left and south to about 400  m above sea level. NHN opposite the front spur of the Neuberg below the debris cone of the Neuberg castle ruins on the spur height, 0.6 km and below 0.1 km². Rises at a little over 480  m above sea level. NHN a source on the upper slope of the Hackenberg .

geology

The Seebach rises and flows into the Gipskeuper ( Grabfeld formation ), which is present throughout the central part of the valley. Right over it on the up to about 464  m above sea level. NHN high and narrow plateau of the Neuberg -sporn, which barely dips towards the top, there is a narrow strip of reed sandstone ( Stuttgart formation ), which also spreads out on the opposite side of the valley on the central slope of the Hackenberg. There the slope then rises over the Upper Bunter Marl ( Mainhardt Formation ) to a narrow, but again very flat plateau in the silica sandstone ( Hassberge Formation ) with a maximum altitude of 511.6  m above sea level.
