The Tünken Bach is a two hundred meter long low mountain range in the area of ​​the Hattingen district of Blankenstein in the North Rhine-Westphalian Ennepe-Ruhr district .

geography

course

The Tünken Bach arises from three spring branches in a wooded area south of Blankenstein Castle and south of the Alte Ruhr-Katzenstein nature reserve .

The northern branch rises from the source pond at Kielschem Haus , Im Tünken 4 . The previous building was a school building. In 1798, the teacher Johannes Bockhack reported: “The school is at its outer end, even outside the city located on a high mountain, in the depths and directly at a dangerous pond into which several people have already fallen.” The middle branch rises at an altitude of about 101  m above sea level. NHN and joins after a few meters with the northern branch. A third forest ditch then flows a little downstream from the south.

The unified brook now flows in a wide arc in a north-easterly direction through a wooded Kerbtal , then enters the nature reserve and shortly afterwards seeps into the ground in a marsh area west of the tracks of the Hattingen-Hagen railway line .

It finally flows into the area of ​​the Old Ruhr at an altitude of about 72  m above sea level. NHN underground and from the left into the Pleßbach approaching from the southeast .

The 243 m long course of the Tünken brook ends about 29 meters below its source, so it has a mean bed gradient of about 12 ‰.

Catchment area

The catchment area of ​​the Tünken Bach is drained through it via the Pleßbach, the Ruhr and the Rhine to the North Sea.

Most of it is forested and there is a wetland in the area of ​​the estuary.

  5. ↑ According to the DGK5 and the OSM, the stream seeps into a wetland, but according to the water quality report it should flow into the Pleßbach . The entire area around the Pleßbach is a swamp area, so that indirect drainage will take place via the swamp into the Pleßbach.
