The Elsäßerbach is a brook in the municipal area of Bühlertann in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the upper Bühler from the right above the eponymous capital of the municipality after a west-northwest run of about one kilometer in length .

geography

course

The Elsäßerbach arises in a valley to the west of the Bühlertanner hamlet of Halden, which stands on a central land platform below the Tannenburg . The longer left source branch begins as a ditch a little north below the hamlet of Heuhof at an altitude of about 420  m above sea level. NN . From here the stream flows continuously in the corridor west-north-west, but initially quite unsteadily in an only moderately steep terrain notch. After less than 300 meters, coming from Halden from the east-northeast, the somewhat shorter, but somewhat more catchment-rich, but naturally inconspicuous right source branch flows at about 398.7  m above sea level. NN to. This is followed by a section of over 400 meters on which the now quite natural course of the stream shows weak meanders and is accompanied by a sparse, then partly covered with forest trees and denser, then again exposed wood gallery. For the last 400 meters or so, the stream runs straight and bare between fields and meadows in a field ditch at the wedging right Bühlertal foot and through the very flat right flood plain to the confluence with the middle Bühler at about 376  m above sea level. NN , which it reaches about 500 meters downstream of the isolated willow mill of the village of Bühlertann, which begins about twice as far downstream.

Catchment area

The Elsäßerbach drains an area of ​​about 0.6 km² west-northwest to the Bühler. The highest point in the catchment area is on the northeast corner on the spur of the Tannenberg an der Tannenburg at around 485.7  m above sea level. NN . From the estuary in the north-west to there, the watershed rises uphill in two steeper stretches, on the other side lies the drainage area of ​​the lower Bühler tributary Dammbach . Behind the eastern and southern, most of which run on the central terrace, the Avenbach drains the landscape above the Bühler.

The Elsäßerbach occurs on the western edge of the Franconian-Swabian Forest Mountains counting natural environment Ellwanger Mountains and flows into the Vellberger Bay Keuper exit bay called Buhler, a subspace of Hohenlohe plain . The two streams begin in the estheria layers of the upper Gipskeuper ( Grabfeld formation ) a little below the step of the terrain surrounding the valley on the reed sandstone ( Stuttgart formation ), on which Halden and Heuhof stand. At Heuhof there is still an island of Unteren Bunten Mergels ( Steigerwald Formation ) above it, which stretches out as its western spur on the ascent to the Tannenberg. The castle above occupies the western tip of a flat wedge on the silica sandstone ( Hassberge formation ). The two upper courses of the brook unite in the middle gypsum horizon of the Gipskeuper, after which the brook then runs over a narrow estuary that it has filled up to the edge of the Bühleraue, crosses the wide floodplain sediment band in it and then flows out.

The catchment area is in the municipality of Bühlertann and includes the southern half of the Tannenburg, the western part of the hamlet of Halden and the hamlet of Heuhof.
