The Erlenbach is a flatland brook about one kilometer long in the area of ​​the city of Crailsheim in the district of Schwäbisch Hall in northern Baden-Württemberg , which flows approximately to the west across from the Upper Jagstbahn and the Jagstheimer Stöckenhof from the right and east into the Upper Jagst .

geography

course

The Erlenbach arises at about 414  m above sea level. NHN in Gewann Erlensee between Crailsheim- Jagstheim and - Ingersheim , a damp flat meadow triangle on the west side of the B 290 that is often frozen over in winter , which here after changing to the right side of the Jagst near the Jakobsburg farmstead at the foot of the slowly rising north-east from the river Lerchenberg hill ridge runs along. Other nearby district names suggest that there was once a small lake district with different directions of flow.

The Erlenbach runs in a straight line from near one of the few larger bushes next to the main road in a grassy ditch about westwards and initially has sporadic bushes on the bank. It is mostly accompanied by a strip of meadow. On the lower half of its course its bank is bare, on the last 30 meters it runs underground. It flows out to about 403  m above sea level. NHN and opposite the Upper Jagstbahn and the Jagstheimer Stöckenhof from the right and east into the Upper Jagst .

The Erlenbach is 1.0 km long and experiences a mean gradient of about 11 ‰ on this route. It has no tributaries.

Catchment area

The Erlenbach drains an area of ​​about 0.4 km², whose with about 444  m above sea level. NHN is the highest point on the Lerchenberg ridge in the far east. Behind this, the Seeäckergraben predominantly drains the area on the southeast side of the Jagst above Jakobsburg. On the northeast side, the Alte Seebach leads the drain beyond the watershed, which is barely noticeable here and in the entire western part, over the Tümpfelbach to the Jagst below.

The geological layers in the catchment area are the Gipskeuper ( Grabfeld Formation ) in the upper, south-eastern catchment area , then down below the Lettenkeuper ( Erfurt Formation ) and finally in the vicinity of the Jagst, which flows here with very little gradient, its accompanying floodplain sediment strips. The damp headwaters at the foot of the Lerchenberg around the main road and the Erlensee lake are not very rich in profile, but appear restless on a small scale. The reason for this could be uneven leaching of the gypsum keuper in the subsoil, but also the construction of ponds in earlier times, of which, however, no remnants of the dam can be seen in the area.

The almost completely open area, comprising grassland and fields, lies on the southern edge of the lower natural area Crailsheimer Bucht of the Hohenloher and Haller level to the lower natural area Crailsheimer Hardt of the Frankenhöhe . It belongs to the urban area of Crailsheim and is completely uninhabited.

Protected area

The drainage area of ​​the Erlenbach is located in the Jagsttal landscape protection area with adjacent areas between the district border towards the Ostalbkreis and the bridge of the federal highway 290 over the Jagst near Wiesmühle .
