The Hintere Breg is a 4.5 km long low mountain range in the urban area of Furtwangen in the Black Forest in the Black Forest-Baar district of Baden-Württemberg , which flows into the upper Breg from the right in the city center .

geography

course

The Hintere Breg rises south of the Rothansenhof at about 1000  m above sea level. NN . It soon flows northwest through the Mäderstal. Then it slowly changes to northeast. In Furtwangen on the university grounds, it finally flows in an east-northeast direction at about 853  m above sea level. NN into the upper Breg, which is not twice as long here . Overall, it therefore makes an almost semicircular arc to the north to the left around the local mountain ( 1028.8  m above sea level ). Your sole falls on this route with an average of about 32 ‰.

Catchment area

The Hintere Breg has a catchment area of ​​10 km², which is naturally included in the sub-area of ​​the Southeastern Black Forest of the Black Forest . In the longest extent it extends from its maximum point to about 1110  m above sea level. NN southeast of the Hinteren-Breg-Quelle at the Rothansenhof near the summit of the Kohlwasens ( 1112  m above sea level ) almost 6.0 km north-northwest to about the Raben; across it it is at most just over 3 km wide.

In the north and east it borders on the catchment area of ​​the receiving Breg . The Linach rises in the southeast just across the watershed, and for a short stretch a tributary of the Urach rises . Both ultimately drain into the Breg and with it the Danube , the following ones into the Wilde Gutach and thus over the Elz to the Rhine , which is why the western watershed is part of the European main watershed between the two large rivers. In the southwest, the right upper course of the Heubach competes with the Wilde Gutach, further north its own tributary Bregenbach , most recently the Wilde-Gutach tributary Teichbach .

The entire catchment area lies in the urban area of ​​Furtwangen. The greater part of it is forested. Newer settlements take up a large part of the left slope from the inlet of the Staatsbergbach.

Tributaries and lakes

Hierarchical list of tributaries from source to mouth. Length of water, catchment area and altitude according to the corresponding layers on the LUBW online map. Other sources for the information are noted.

Origin of the rear Breg at about 1000  m above sea level. NHN almost 200 meters southeast of the Hansen farm on the edge of the forest. The stream initially flows northwest through the Mäderstal .

  • Schnabelstalbach, from the right and east to about 894  m above sea level. NN am Sägehof, 2.0 km and approx. 1.5 km². Arises at about 1040  m above sea level. NN east of the Upper Schnabelshof in the forest.
  • Hohtalbach, from the left and south to about 881  m above sea level. NN at Gurbeleck, 1.7 km and about 1.9 km². Flows at about 965  m above sea level. NN at the house level yard a pond. From here about north-northeast.
  • Staatsbergbach, from the left and northwest to about 873  m above sea level. NN at the beginning of the closed development of Furtwangen north of the valley sports fields, 1.5 km and approx. 1.3 km². Arises at about 1000  m above sea level. NN on the southern slope of the Staatsberg ( 1059  m above sea level ). AB here about northeast.
    • Dorerhofbach, from the right and southwest to less than 880  m above sea level. NN at the intersection at the foot of the residential development on the southeastern state mountain slope, 1.0 km and about 0.8 km². Arises at over 960  m above sea level. NN below a pond at the Staatsberghof.
  • Ganterhofbach, from the left and northwest to about 864  m above sea level. NN immediately in front of the bath, 2.4 km and about 1.5 km². Arises at about 998  m above sea level. NN south of ravens in the forest sounded Ganterloch .
  • Ilbenbach, from the left and northwest to about 860  m above sea level. NN after the bath, 1.6 km and about 0.7 km². Arises at about 950  m above sea level. NN at the ski jump next to the road from Raben to Furtwangen

Mouth of the Hinteren Breg from the right and finally west-southwest to about 853  m above sea level. NN in Furtwangen in the Breg . The stream here is 4.5 km long and has a catchment area of ​​10.0 km².

geology

Metamorphic paragneiss can be found almost everywhere in the catchment area . On the dividing ridge between the valleys of the upper Hinteren Breg and its first right tributary Schnabelstalbach there is Heller Gang magmatite from the Paleozoic . The north-westerly moving upper course of the stream roughly follows a suspected fault line.
