The Würzbach is a stream in the north-eastern Black Forest in the Baden-Württemberg district of Calw , which flows from the right into the lower Kleine Enz after an approximately 8 km long, approximately northwest run on the southern edge of the Calmbach district of Bad Wildbad .

geography

course

The Würzbach arises a good one and a half kilometers south of the church in the Oberreichenbach village of Würzbach at around 689  m above sea level. NN in the horn forest . The stream initially flows north-northeast and after just under half a kilometer it enters the cleared island around the village. After crossing under the road to Rötenbach ( Bad Teinach-Zavelstein municipality ) less than a kilometer further and having passed the first houses in the southern part of the village of Würzbach on the left bank, he turned to the northwest for most of his course.

Near the center of the village it crosses the K 4325 leading from Oberreichenbach to Agenbach (municipality of Neuweiler ). Only a little later the stream enters a small valley forest on the edge of the northern part of the village, where it is met by the Seltenbach, which is only slightly smaller in length and catchment area feeds. Now, for almost half a kilometer, the Würzbach separates the hamlet of Naislach on the left from the village named after it on the right in its now steeper, forest-filled hollow . Thereafter, opens at the northern edge of the first major right inflow Front Rotenbach , the part of the Moors Bruck had dehydrated in the Northeast.

In his now more and more deepened, on the slopes and in most cases on the valley floor wooded V-shaped valley of Würzbach passed the art and then the Lower Mill . After the village's sewage treatment plant, it passes under the former Havelsburg on the upper right slope. In the next small clearing a nearly a kilometer long side channel branches off to the right, the right to come up Föhrenbächle in the forest area Wake Hart receives and at the inlet from the source rocks Höllbrunnen runs back in the Würzbach on the right foot of the slope. Two more times in the Würzbach valley, old canals also branch off to the right, then the forest opens into a triangular small valley with a fish farm made up of numerous small ponds, in which now at around 448  m above sea level. NN which is accompanied on the right slope by the federal road 296 from Calw and with a length of 4.2 km, the most important tributary, the Blindbach, flows out of its Kerbtal from the right and east-southeast.

Then the valley forest closes again between the mountain forest ridges Heimenhart left and Kälbling right. In the soon following, widening estuary clearing, there are further fish ponds on its course. Between the first houses in the south of the Bad Wildbad district of Calmbach , the Würzbach reaches the edge of the lower valley of the Kleine Enz , into which it finally descends after crossing the federal road 294 at about 410  m above sea level. NN flows into the valley from the right and south-east, which is now more than 250 meters deep.

After its 8.4 km long run with an average bed gradient of about 33 ‰, the Würzbach flows about 279 meters below its origin.

Catchment area

The Würzbach has a catchment area of ​​21.6 km², which is inscribed in a rectangle, which extends in north-south direction about 7.5 km and perpendicular to it about 4.5 km. With about 746  m above sea level. NN highest point of the catchment area is about 2.5 km southwest of Würzbach in the Fronwald . From here, its border stretches northwards to the mouth, beyond which the water flows over short streams to the west to the upper course of the Kleine Enz receiving water . The northern and northeastern border section adjoining the mouth runs over the separating ridge Kälbling to the edge of the clearing island around Igelsloch and separates from the catchment area of ​​the Calmbächles, which flows slightly downwards in Calmbach into the Kleine Enz . The competitors behind the remaining long border section in the east and south back to the highest point, the Kollbach , the Schweinbach , the Rötelbach and finally the larger Teinach with its left tributaries, all drain eastwards to the Nagold .

The highest in the catchment area is its southwest corner, here the terrain reaches about 745  m above sea level. NHN . The upper catchment area is naturally part of the sub-area of ​​the Black Forest-Randplatten , the lower from the beginning of the Unterlauftal after the two places on the run to the sub-area Grindenschwarzwald and Enzhöhen of the Black Forest .

There are open corridors in the catchment area mainly in the approximately 3 km² clearing island around Würzbach, while the small Untertal and even smaller Mitteltal and plateau clearings together remain well below 0.5 km². The municipality of Oberreichenbach has the dominant share in the area, and the mouth triangle with an area of ​​around 2.5 km² belongs to the Calmbach sub-district of the city of Bad Wildbad . The only localities are the village of Würzbach and the hamlet of Naislach opposite it west of the Würzbach in the common clearing island and at the mouth a small gusset near the mouth of the Calmbach district of Bad Wildbad.

Natural spaces and geology

In terms of nature , the area in the northern Black Forest is divided into two parts. The south and a wide strip in the east, a total of slightly less than half of the area, belong to the Black Forest edge plates , a low-profile plateau with flat and only short upper streams. The entire other part lies in the natural area of Grindenschwarzwald and Enzhöhen , this is where the longer, heavily cut valley sections of the Würzbach and its large tributary Blindbach lie .

The Würzbach cuts into the three great layers of the red sandstone . The Upper Buntsandstein stands on the southern plateau and extends far towards the mouth of the three wedging mountain ridges between Upper Kleiner Enz and Würzbach, between Würzbach and Blindbach and between Blindbach / Würzbach and Calmbächle. Even before entering the settlement areas of Würzbach and Naislach, the Würzbach and its not much smaller upper left inlet Seltenbach enter the Middle Buntsandstein , similarly early the Blindbach. This layer first stretches down into the valley as a broad strip, then continues as a double band on the slopes. The lower red sandstone reaches the Würzbach soon after the inlet of the rear Red Bach, in it - or possibly in the underlying Zechstein - it flows into the Little Enz Three sites are parts of larger ones. Quaternary flat ground, Forest Moor islands on flat saddles to neighboring valleys of the Upper Bunter on. More information about the moors under →  Protected areas and biotopes

Protected areas and biotopes

The entire catchment area belongs to the Black Forest Middle / North Nature Park , the portion west of the Würzbach stream below the village of the same name is part of the landscape protection area Großes and Kleines Enztal with side valleys . The area is characterized by a number of not very deep bogs, called Müssen in the region , partly because of their typical saddle location over the less prominent watersheds into neighboring catchment areas. The largest contiguous must areas are

  • the Hesel-, Brand- and Kohlmüssen in an arc from southwest to west about 1 km from Naislach; Strangely enough, on the map and in aerial photos they have no noticeable course towards the Würzbach;
  • the Bruckmüsse similarly far northeast of the village of Würzbach drains over the Vorderen Rotenbach into the Würzbach, in the center it is even an upland moor , which is, however, severely disturbed by former peat extraction ;
  • The origin of the largest tributary, the Blindbach, lies in the Lachenmüsse, which is mainly drained by it .

The first two of the three areas are nature reserves , the Bruckmüsse is with little different demarcation under the name Waldmoor-Torfstich also a protected forest. Elsewhere, too, smaller musts are at least under biotope protection, at the corridors of Seltenbach and Würzbach there are also some wet meadows and in the surrounding corridor there are several field hedges.
