The Baiersbach is a nearly one kilometer long eastern and right brook to Nagold on the eastern edge of the Black Forest to the Oberen Gäuen and flows in the urban area of Calw in the Calw district in western Baden-Württemberg .

geography

course

The Baiersbach usually rises at about 475 m above sea level. NHN in the Waldgewann Baiersbach on the border of the Calw districts of Stammheim and Holzbronn and runs from there westward through a wooded Kerbtal, first on, later near this border on Stammheim area. After 0.9 km it flows below 350 m above sea level. NHN from the right into the east loop of the Nagold around the spur of Waldeck Castle and just before the Waldeck courtyard under it on the opposite side of the river.

Catchment area

From a natural point of view, the eastern part of the approximately 1.6 km² catchment area lies in the lower Würm-Heckengäu area of the Upper Gau , while the more consistent course lies in the Black Forest fringes of the Black Forest . The natural boundary follows the boundary between the shell limestone of the Gäue and the red sandstone of the Black Forest. The highest point in the catchment area nn its northern tip near the summit of the summit Thumb reaches about 603 m above sea level. NHN .

The rivers that compete on the other side of the watershed also drain directly or indirectly to the Nagold. In turn there are:

in the northwest the brook through the Rehgrundklinge ;
in the north the Winkelbach , which initially feeds the Schlittenbach ;

in the east the Fischbach , which initially feeds the Agenbach ;

in the south the brook through the Xander blade .

Tributaries

In the catchment area, near the district road K 4302 from the B 296 down into the Nagoldtal, there is an even higher spring in the main line trough at around 535 m above sea level. NHN . Downstream of its usual source it has a left and a longer right tributary, both of which are volatile and at heights of up to 540 m above sea level. Arise from NHN .

character

The water is a mountain stream, the higher sources of which lie in the shell limestone and which has torn a small gorge into the red sandstone below on its more permanent section. On its first two hundred meters, the run disappears in deposited calcareous sinter . Then it runs over many terraces and basins that were formed by the larger chunks of fallen sandstone here. In the lower valley, too, the stream can dry up at times.

The middle and lower part of its valley lies in the Nagoldtal conservation area around the course of the Black Forest river.
