The Xander blade is a little more than one kilometer long, west-southwest of the right to Nagold running forest sword of the northeastern Black Forest . It is mainly located in the urban area of Calw in the Calw district in Baden-Württemberg . The stream that runs through it is already a little above the Klinge on the plateau and is almost two kilometers long until it flows into the Nagold.

geography

course

The stream through the Xanderklinge is created in a permanently open course at the northern exit from Calw- Holzbronn the K 4301 at about 498  m above sea level. NHN as a ditch next to a soon grassy farm road and runs its first 300 meters between fields approximately to the west. Then it is dammed into a 0.4 hectare extinguishing water pond with a wooded edge and a small tree island. From here it flows out in a west-southwest direction from now on and plunges into its forest gorge, which has cut picturesquely into the red sandstone of the Black Forest. With a steep gradient it flows down to the Nagold over several small waterfalls. At the edge of the floodplain, the floodplain, it is crossed by the Nagold Valley Railway and the federal road 463 , less than a hundred meters afterwards it flows out at about 353  m above sea level. NHN from the right into the middle Nagold below the valley mill at the foot of Holzbronn.

After a 1.7 km long run with an average bottom slope of about 145 meters above sea level, the stream flows below its start.

Catchment area

The stream has a catchment area of ​​around 2.0 km². which is mainly located on the plateau around Holzbronn, is mostly open and forms a wide and tub-shaped natural hollow that slopes down towards the Xanderklinge. In the extreme northeast there is already a 594.2  m above sea level in the forest . NHN high, apparently nameless elevation, the summit of which is the highest point of the catchment area. Behind this and behind the southeastern watershed, Fuchtbach and Eulenbach collect the runoff on the other side and lead it over the Fischbach and then the Agenbach further up to Nagold near Wildberg. Closer to the south, the catchment area of ​​a smaller right brook, which flows closer to the Talmühle, borders the Nagold. In the north, the Baiersbach drains the next right forest blade to the Nagold. From a natural point of view, the entire area lies in the sub-area of ​​the Black Forest fringes of the northern Black Forest . In the catchment area, from its highest point in the very north-east to Nagold, the layers of the Middle and Lower Muschelkalk as well as the Buntsandstein follow one another down to the corner formation . The course begins in the Lower Muschelkalk and changes a little below the lake over a fault line into the red sandstone of the Xander blade.

The catchment area belongs mainly to the Holzbronn district of the city of Calw ; inside lies the greater part of the village of Holzbronn, the only place in the catchment area. On the Nagoldtalhang in the south, a completely wooded strip of the partial boundary of the small town of Wildberg stretches to the left bank of the stream in the lower Xanderklinge.

Tributaries and lakes

Above the point where the creek ditch arises on the northern edge of Holzbronn, there are a few ditch courses up to 0.8 km away in its valley basin that continues upwards to the north-east, but none of them have a continuous open course ; the longest of the trenches begins at about 530  m above sea level. NHN on the northern edge of the Garweiden to the forest. There are no other significant tributaries besides these.

The aforementioned extinguishing water pond is 0.4 hectares in size, its water level is over 490  m above sea level. NHN .

Nature and protected areas

The lower part of the deep, V-shaped gorge is accessible and indicated in several hiking guides. There are small steep and large sloping drops in the middle blade. There is rubble there and there are pools in the bed . Partly steep rock faces rise up on both sides, also with overhangs and small caves. A large part of the Klingengrund is designated as a forest biotope. At the height above the gorge there is a viewing platform that offers a view over the Klinge and the Nagold Valley.

The brook runs completely within landscape protection areas, on the lower reaches through the landscape protection area Nagoldtal , in the upper part through the landscape protection area Validlinger and Holzbronner Heiden . Large parts of this on the heights belong to the nature reserve of the same name; these are dry grasslands typical of the Heckengäu and a remnant of a pine forest . Near the highest point, a fragment of the edge of the water protection area mountain, valley, bush and Fuchtbach springs protrudes into the catchment area
