The Cröffelbach is a creek a little over a kilometer long from its blade run in the area of ​​the municipality of Wolpertshausen in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows into the lower Bühler from the right and east in the hamlet of Cröffelbach .

geography

Upper course

The initially flat hollow of the Cröffelbachtal begins on the plateau around Wolpertshausen a little east of the village. A ditch that only carries water intermittently is created in a field barn a few hundred meters east of the local border at about 443  m above sea level. NHN . This ditch runs almost dead straight next to fields and then past the southern edge of Wolpertshausen to the west-south-west. At the edge of Reinsberger Straße (K 2569), he takes a less than 0.7 km long, also only periodically water-bearing field path ditch from the left, which shortly before drained a 0.2 hectare square pond on the roadside, probably a fire extinguishing pond for the municipal seat on the karst plateau. Then it crosses under the road and immediately on the other side of it, after a total of about 1.2 km of inconsistent run, it is lost in a fallow, herbaceous slab at the edge of the meadow at about 423  m above sea level. NHN .

The trough center lines continue approximately to the southwest over predominantly fields. At the southern tip of the Wolpertshausen development, it reaches the beginning of the Lochklinge after another 0.6 km ,

course

There now begins at about 415  m above sea level. NHN , accompanied by a tree gallery, which widens as it deepens to a forest of blades , the bed of the Cröffelbach, which initially still carries inconsistent water. In this then steep, initially west-south-west pulling hole blade , up to 25 meters high rock walls stand next to the rubble in the valley floor, to which small rivulets from the valley sides run from sinter springs. At about 330  m above sea level. NHN the Bühlertal slope becomes flatter and the valley floor initially opens to the left to the corridor, the stream now flows westward. Passing two loops on the right-hand side of the Cröffelbacher Steige north of the Cröffelbach, the stream reaches about 290  m above sea level. NHN the outskirts of the valley hamlet Cröffelbach. There it crosses the Bühlertalstrasse (K 2667) on the right of the river and then flows a stone's throw below the weir of the river at around 265  m above sea level. NHN from the right and east into the lower Bühler .

On its approximately 1.3 km long open section from the beginning of the Lochklinge, the Cröffelbach loses about 150 meters in height with an average bottom gradient of 110 ‰.

Catchment area

The Cröffelbach has a catchment area of ​​2.5 km², which is largely on the plateau. It begins in the east at the striking Wolpertshausen water tower at the highest point a little over 450  m above sea level. NHN and extends about 3.2 km west-southwest to the mouth.

The longest stretch of the catchment area of ​​the Klingenbach borders on the north-northwest watershed from the mouth to the water tower, which flows into the Bühler just a hundred meters below the Cröffelbach, and finally that of the Haßfelder Grimmbach over a short stretch , the west over the lower Grimmbach drained to the cooker . At the water tower the catchment area boundary bends southwards, now the Urtelsbach drains in a strongly karstified landscape over the Schmerach into the Bühler above, before it bends north of Reinsberg to the west, now the creek also competes with the Bühler through the cress blade .

The catchment area is part of three natural areas : At the very top, the upper course rises in the east wing of the Haller level , also known as the Ilshofen level , a sub-area of ​​the Hohenlohe and Haller levels . Its shrinkage is already in the Kocher-Jagst plains in the sub-area of Eastern Kocher-Jagst-Riedel , in which, further down, the origin of the Cröffelbach itself and the upper perforated blade lie. The remaining part belongs to the sub-area Middle Kocher and Lower Bühlertal .

The upper trench is formed in the transition area between the well to the natural environment which gradually forming limestone still lying under Keuper ceiling and in the most catchment shares is still covering Lössderivats that on quaternary back deposit. Half of the left watershed runs in this younger layer. The Cröffelbach itself arises at the beginning of the blade in the Unterseuper, in the perforated blade it reaches the underlying layer of shell limestone, in which it forms its gorge-like valley in the upper shell limestone . The gradient is lower in the Middle Muschelkalk , it finally flows into the Lower Muschelkalk , which begins a little above Cröffelbach on the valley floor of the Bühler. To the left of the lower reaches, on the west spur Eichelberg of the plateau, there is an 8-hectare field of sinkholes with a crevice.

On the plateau the landscape is largely open; there are only small woods on two knolls at the edge. From the perforated blade and up to the city limits of Cröffelbach the creek in running conservation area Bühlertal between Vellberg and Geislingen with side valleys and adjacent areas .

The entire catchment area belongs to the municipality of Wolpertshausen.
