The Wettbach is a four kilometer long stream in the urban area of Schwäbisch Hall , which flows into the Kocher from the right and east . Its lower gorge valley is the Wettbachklinge .

geography

Course and geology

The betting Bach created between fields on quaternary loess - sedimentary north of the airfield Schwäbisch Hall Weckrieden next to the southward current leg of a field Crossroads between long meadows and armed Busch . Accompanied from the beginning by a row of trees, it flows a few meters to the south towards the airfield and then turns into a curve to the west, crosses under the northeast bypass of the city and behind it runs as a deep, straight ditch with sparse trees through the damp meadow hollow of the Eichwiesen , here now in the Lettenkeuper edition ( Erfurt formation ) of the Haller level . At the crossing under the L 2216 Schwäbisch Hall – Ilshofen two kilometers below the source, it crosses the settlement contour of the city and touches the soft image of the Weckrieden district with the right bank, while the development of Hall stops on the middle slope on the left. It turns to the southwest and after another three hundred meters begins a new type of valley section.

Here he reaches the Upper Muschelkalk and enters the Wettbach klinge , a wooded gorge that deepens rapidly and steeply, in which he falls over limestone banks and where a sidewalk accompanies him on the right along the entire length, while to the left, behind trees and the The edge of the slope hardly ever visible, the Haller Kreuzäckersiedlung draws to it. After almost a kilometer, it turns abruptly in front of the Galgenberg (up to 360.3  m above sea level ) to the northwest. On the less steep right slope there are some more or less overgrown garden plots, the partial terracing of which suggests earlier viticulture. At the foot of a stone arch bridge that crosses the valley from half slope to half slope, he enters the settlement area of ​​the city in the street "Wettbach". Here he turns to the west, briefly passes the old Nicholas cemetery on his left in a brick trough open to the outside wall and then disappears into an underground canal on the southern edge of Heilbronner Strasse ( B 19 ). In this it runs through Salinenstraße to its south bend and then after a few meters in the brick building of the district heating plant flows into the open channel from the right into the cooker , whose bed is already in the Middle Muschelkalk .

Tributaries and catchment areas

The Wettbach has a few ditch inflows from the trough sides in the upper reaches, but these often dry out. In the further course there is no manifest inflow. In summer it itself often dissolves in the blade on puddles standing in a chain.

The Bet Bach drains a 3.0 square kilometers large catchment area, the nature spatially predominantly in the subspace Haller level of Hohenloh and Haller plane is located, with the muzzle near the western part in the subspace Haller bay with rose garden . The 410  m above sea level NHN's highest point is on the northern border in the Gewann Heide on the L 2219 between the roundabout at the north-east bypass Schwäbisch Hall and the hamlet of Veinau .

In the east in the area of ​​the airfield, the Otterbach competes behind the barely recognizable watershed in the opposite direction to the Bühler , all other competitors flow to the Kocher . This is in the south-east on a short stretch of the Waschbach through Hessental and Steinbach, then the Badersklingenbach and finally in the south-west the Schuppach , of whose completely twisted course in the city area today only the gorge-like incision of the Crailsheimer Strasse testifies. In the west, the narrow Galgenberg separates the lower Wettbachtal from the Kocher valley. In the north, the catchment area of ​​the Wettbach only touches the other reasonably constant Kocher tributaries far from the Kocher valley edge in the area of ​​the upper reaches, namely that of the Eltershofer Bach for a short time and a little longer and in the northeast that of the Diebach .

River history

At the bend of the blade there is an old valley floor about 40 m above today's valley level in an upward continuation of the lower reaches. Rebuilt at the turn of the 21st century with the residential street An der Ziegeleihütte , this wide hollow, also known as Langenfeld in earlier times, flowed towards the Wettbach between Galgenberg in the west and the slope of the Kreuzäckersiedlung in the east of the Schuppach . The route can be traced for almost half a kilometer in the area, at its end the mentioned Schuppach flows in its younger lower reaches through the steep blade south of the Galgenberg to the Kocher used by the Crailsheimer Steige . He's completely perverted today. The old brickworks that can be heard in the street name used the deposited floodplain.

history

The bridge structure, which stands at the exit of the Wettbachklinge to the settlement area of ​​the city in the valley, was formerly an aqueduct, over which the imperial city of Hall was supplied with spring water in a natural gradient, initially through a tube drive and later in a stone channel. The sources were about one and a half kilometers from here at Breitenstein in the north, the route, which a hiking trail follows today, fell fairly steadily on the right slope of the Kocher in the direction of the city. Next to it there are sometimes gutters to be found. A semi-cylindrical channel was restored on the center line of the accessible aqueduct during a repair with hollow stones laid one behind the other.

environment

The Wettbachklinge and the northern Galgenberg are part of the Kochertal nature reserve between Schwäbisch Hall and Weilersbach with side valleys . In the area of ​​the Wettbachklinge some hedge biotopes are under protection as well as parts of the natural stone walls between the hiking trail and the gardens on the right slope. On the northern Galgenberg, three English oaks are protected as natural monuments.
