The Lanzenbach is a brook in the district of Schwäbisch Hall in northeast Baden-Württemberg , which flows into the Bühler from the right and northeast in front of the hamlet of Eschenau in the small town of Vellberg .

course

The Lanzenbach rises south of Frankenhardt -steinehaig at about 458  m above sea level. NN at the edge of the forest of the Hanglich and begins between the Hanglich and Egerten its course to the southwest, on which it soon crosses to Vellberger district. It reaches the foot of the path of the L 1064 Vellberg - Gründelhardt and takes the Hanglichbach from the left , and immediately afterwards the Egertenbach from the right in an already open corridor . In a further hollow it flows next to the L 1024 towards the hamlet of Schneckenweiler , before which the Lindenbach reaches it from the left and the Stockäckergraben from the right . Below Schneckenweiler it passes Merkelbach , where it crosses the K 2619 Merkelbach - Untersontheim branching off from the main road. Below Merkelbach it runs through the Eschenauer Muschelkalk quarry and then reaches about 355  m above sea level. NN and after 3.8 km from the right the Bühler.

Catchment area

The catchment area of ​​the Lanzenbach covers around 4.7 km² and, apart from the narrow marginal strips towards the Frankenhardt area, lies mainly in the Vellberg district. It is a wide hollow in Gipskeuper and Unterkeuper , which only reaches the Upper Muschelkalk in the area of ​​the quarry and on about the first half of two western mountain ledges, on the right Hackenberg , which follows the Vellberger Schlegelsberg downhill , and on the left Hahnenberg , which ends in the Hammerberg , is accompanied, which at least reach up to the silica sandstone. On the upper Hackenberg , a clod of slope has torn off in a line and slid down into the valley. On the upper ascent to the silica sandstone there is forest everywhere, on the lower you can see the typical restless slopes of the Gipskeuper with sinkholes, furrowed hollows, crooked fruit tree trunks and on the map oscillating contour lines. In the upper valley, on the left on the middle slope above the Corbula bank of the Gipskeuper, the two small plateaus Lindenbühl and Birnbach , which are plowed, lie like platforms . In the area of ​​the quarry in front of the mouth, the brook crosses the fault line of the Vellberg Fault, the north-eastern floe of which lies dozens of meters lower than the south-western one, which is why the brook changes abruptly into the shell limestone. The fault is currently (as of 2010) at the edge of the edge of the quarry in front of the Hammerberg clearly recognizable by a shift in layers (deep clod to the northeast).

character

The course of the stream up to the entrance to the open corridor is quite natural, even at the tributaries. In the wide basin, the further down the valley, the more human intervention can be seen in the course and bed profile. The Lanzenbach runs underground or inconspicuously in a recessed channel next to a service road through the quarry, the bottom floor of which is deep below the level of the stream. Settlement in the valley is limited to the two Vellberg hamlets mentioned. Besides these, only Steinhaig is touched by the catchment area.
