The Steinbach is a creek less than two kilometers long in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the Mühlkanal next to the central Jagst from the right and east just before the hamlet of Mistlau in the small town of Kirchberg an der Jagst .

About four and a half kilometers further downstream, the Jagst in the same urban area runs into a larger Steinbach, also from the right.

geography

course

The Steinbach rises inconsistently about 1.1 km northeast of the center of the Satteldorf hamlet Bölgental on the southern edge of the Anhäuser forest to Feldgewann Langenloh at about 450  m above sea level. NHN and runs steadily approximately westwards. After about 500 meters to the west, at a crossing of the brook through a road from Bölgental to the Aussiedlerhöfe Im Morgen from Kirchberg an der Jagst from the northern Anhäuser Wald, a second, about a third longer source branch flows south-westwards. Here the stream reaches the municipal boundary to the town of Kirchberg, and also the notch of the shell begins sword of the stream. In this forest-covered, narrow gorge, the stream falls on its middle course, which is also about 500 meters long and about 440.3  m above sea level. NHN at about 390  m above sea level. NHN .

Then the stream, initially accompanied by wood on the banks, runs through the lower part of the open, flat, sloping valley floor of an old hunting loop, between the 20 meter high Umlaufberg on the left and the 50 meter higher old Krallhang Kropfberg on the right, both of which are overgrown with forest. After about 700 meters on this lower section, the Steinbach flows a little below the weir at about 350.2  m above sea level. NHN in the outgoing canal of the Mistlauer Mühle to the right of the middle Jagst , which runs back less than 300 meters down from the river bridge of the hamlet.

The Steinbach is 1.7 km long and has a mean bed gradient of around 58 ‰ on its entire course .

Catchment area

The catchment area of ​​the Steinbach covers around 1.5 km². In the north, the neighboring catchment area borders on a nameless brook, which sinks into a sinkhole and ultimately drains into the Jagst over the next sideline of the river in the center of Mistlau. In the east two streams run in the area of ​​the ruins of the Anhausen monastery eastwards to the Flinsbach , which flows into the larger Jagst tributary Gronach further up the river. On the south-east side, the Rotbach also drains beyond the watershed to the Gronach. Between the southern border of the catchment area and Bölgental, another nameless stream runs through the hamlet of the Jagst.

The predominant eastern part of the catchment area is naturally in the sub-area Bartenstein-Langenburger Platten , the western only with the old Jagstschlinge in the sub-area Middle Jagsttal of the Kocher-Jagst plains . The somewhat larger part of the catchment area in the southeast belongs to the municipality of Satteldorf , the rest to the small town of Kirchberg an der Jagst . The only settlement in it is the Aussiedlerhofgruppe Kirchberger Im Morgen near the northern watershed.

geology

The stream arises between a fairly high remaining layer of old river gravel in the Anhäuser forest and an adjacent layer of loess sediment , both of which are of Quaternary origin. Soon it changes to the Lettenkeuper ( Erfurt Formation ), which covers large parts of the surrounding plateau, which is built up by the Upper Muschelkalk , into which the brook subsequently cut its blade. He then crosses another layer of river gravel on the bottom of the old hunting loop. On the low Umlaufberg, as on the slopes up to today's Jagsttal, there is Upper Muschelkalk.

In the loop of the valley there are two abandoned small quarries, on the Umlaufberg and on the right slope of the Kropfberg , both of which are geotopes. At the quarry at Kropfbergfuß a bioherm of mussels and crinoids is opened. The well-preserved Bonifatius pennies , which were still very common decades ago , now show strong weathering and destruction by hammering.

Nature and protected areas

Around a third of the plateau is forested, the open land consists mostly of fields. The Steinbachklinge and most of the old Jagstschlinge belong to the landscape protection area Jagsttal with side valleys between Crailsheim and Kirchberg , the smaller part of the loop with the Umlaufberg and the Kropfberghang belong to the nature reserve Jagsttal with side valleys between Crailsheim and Kirchberg .
