The Blüßengraben , formerly Pliesengraben and Blöse-grave is a two kilometer long river in Eastern Hintertaunus in the district of Ober-Mörlen in Hessen Wetterau , which from the south coming from the right in the United States opens.

geography

course

The Blüßengraben begins at a height of about 240  m above sea level. NHN in a field on the southern edge of a small deciduous forest around six hundred and fifty meters southeast of Ober-Mörlen and on the southwestern flank of the Eichberg ( 269  m above sea level ), on the southern slope of which the Bad Nauheimer Alte Schanze is located. To the north-east of the spring there is a wild cherry orchard, which is followed by a wood rich in fruit trees to the north. East of the headwaters is the 268  m above sea level. NHN high Johannisberg , which has a number of archaeological cultural monuments .

The Blüßengraben reappears through a passage under the A5

The ditch initially runs just under three hundred meters south-south-west on the edge of a field path through an agriculturally used corridor, then turns north-west of the glider airfield of Ober-Mörlen to the west, and shortly thereafter takes a north-west direction. It now flows through the Blüßen corridor , after which it got its name, under the A 5 / E 451 . A little to the south there is a small apple orchard. A good hundred and fifty meters down the stream it is then fed on its left by a small field ditch. The Blüßengraben then runs in the inflow direction to the north northeast with a small rough pastures - habitat over and achieves after two hundred and fifty meters, the southeast corner of Upper Mörlen.

There it flows under a new building area and the Nauheimer Straße , then moves to the one and two-family houses of the settlement area to the fields adjoining to the east, first the corridor Holzweise and then the corridor Kirchfeld about seven hundred meters north-northwest and finally flows at a height of about 160  m above sea level NHN and at river km  10.9 from the south and right into the USA coming from the west .

Catchment area

The catchment area of ​​the Blüßengraben is drained to the North Sea via Usa, Wetter , Nidda , Main , Rhine .

The headwaters, the upper and middle reaches are in the Nauheimer Taunussporn and only the lower reaches with the mouth area in the Mörlener Bucht . The entire trench extends within the district upper Moerlen.

The highest point is 269  m above sea level. NHN high Eichberg.

Its catchment area borders

  • in the south to that of the Usa tributary Deutergraben
  • and in the west to that of the Hainbach , also a tributary of the USA.

In the catchment area east of the Bachaue, largely cleared arable land dominates, which in the border area of ​​the catchment area merge into grassland with larger orchards with numerous old trees (mainly apples) on mostly narrow plots . The hills are covered with deciduous and mixed forest. Settlement areas predominate in the western area.

Geology and soils

The source area and upper course belong geologically to the Taunus ridge and the lower course with the mouth area to the Wetterau valley .

In the source area of the Blüßengrabens on the slopes of Eichbergs dominate quartzites , shales and sandstones of the Taunus quartzite formation of the Pragian - Group of the Lower Devonian - Series of Devon . Over a meter thick, loess loam rich pseudogley - parabraunerden - soils have deposited over this substrate . In the following stretch to approximately the inflow of the field ditch below the motorway, the Blüßengraben flows through a petrographic zone with undivided Quaternary floating earth made of clay , silt , gravel and sandstone . This is followed by an area with Lower Devonian slate and sandstones of the Emsium group with superimposed mighty loess soils from the Pleistocene. The soil types show a spectrum from pseudogley parabrown soils to gleyified parabrown soils. In the area of ​​the mouth there are undivided sandy and gravelly terraces of the Pleistocene.
