The Wethbach is a 5.7 km long brook on the northeast Hohenlohe plain in the far west of the Ansbach district , which flows into the upper Tauber in Gebsattel from the left and west-southwest .

geography

course

The brook arises about 1.3 km southeast of the Rothenburg town of Bettenfeld next to the district road AN 6 from Insingen - Lohr in the southeast to Bettenfeld in the northwest. From there it runs very steadily in an east-northeast direction. In a fairly flat and almost cleared landscape and initially with almost no wood on the banks, it is on two sections of the district boundary from Rothenburg on the left to the municipality of Insingen on the right bank. After a little over a kilometer, the state road 1040 crosses it from the direction of Rothenburg to Rot am See in Baden-Württemberg (there L 1040), after which it flows at a distance of about 300 meters past the village of Herrnwind in the north-north-west and then briefly crosses into the Insinger district . From here a wood gallery accompanies its shallow hollow, which is only about 20 meters below the level of the edge heights.

Less than a kilometer later, state road 2419 crosses it from Rothenburg in the north to the Insinger district of Lohr in the south; here it finally passes over to the municipality of Gebsattel and soon passes through a 0.3 hectare pond. On his way he then passes a nameless group of houses on the left bank, where he feeds a pond of less than 0.1 hectares and from which he reaches a floodplain ditch about 0.3 km downstream. A little later it touches the southern outskirts of Gebsattel, where it makes its only narrow loop of brook. Then it separates the line of settlements along Hirtengasse in the south from the rest of the Gebsattel in the left Steamer region and flows at the river bridge of Weißenstrasse from the left and finally west into the upper Tauber , just a stone's throw above the mouth of the Kirnberger Mühlbach at the Dorfmühle opposite.

Catchment area and tributaries

The Wethbach has an elongated catchment area of ​​about 5.2 km² in which it runs at most 0.4 km from the right watershed, while the left is up to 1.2 km away on the middle course. Therefore it only has left tributaries. In addition to the aforementioned Auengraben near Gebsattel, only a 0.7 km long ditch is quite permanent, which arises north of Herrnwinden, runs right next to fields and flows southeast of the village; the other tributaries are drying ditches that often accompany dirt roads.

The catchment area lies between those of the other left Tauber tributaries Lohrbach on the right and in the south and the Schandtauber on the left in the west and north. In addition to the lower reaches, the small catchment area of ​​the Wethbachgraben in the north squeezes in front of the Schandtauber.

The highest point in the flat, hilly, eastward sloping, almost forest-free and largely field-covered catchment area lies on its western edge close to the Wethbach origin at about 450  m above sea level. NN high hill; also on its north-west corner between Bettenfeld and Herrnwinden are 449  m above sea level. NN reached.

geology

The reason for the low inflow from tributaries is likely to be the karst formation of the northern Hohenlohe plain. This is where the Upper Muschelkalk, which is susceptible to subrosion, lies in the subsoil . In the wider valley of the brook it is covered by a thin layer of Lettenkeuper ( Erfurt Formation ) and this in turn is covered by Quaternary loess sediment in the ridge layers, especially on the watershed to the Schandtauber in the north .
