geography

Source and history

The Sanzenbach rises about 7.5 km southwest of Schwäbisch Hall on the eastern slope of the Mainhardt Forest above the southwestern tip of the Rosengarten hill landscape . About one kilometer to the west is the Schwäbisch Hall hamlet of Sittenhardt on the plateau (up to 512.5  m above sea level ), about one and a half kilometers east-northeast of the hamlet of Sanzenbach in the municipality of Rosengarten (around 360  m above sea level ). The source itself is located on the forest slope at about 442  m above sea level. NN between the Geißklinge in the north and the Spitalhalden in the east.

In a northeasterly direction the young stream runs down its forest blade and occurs after about 0.6 km and at about 384  m above sea level. NN in a shallow course into the wide bay, about 100 m later you pass three tiny ponds, opposite which the Zimmershaus is on the left slope. After this, a small stream flows from the right from the Spitalhalden , which enters the meadow at the foot of the forest slope from the top of a hedge ledge. 400 m further down the valley, the Sanzenbach passes an herbaceous pond on its left and then turns east. From the Büschelberg to the west of the Zimmertshaus, a forest blade runs out at the edge of the floodplain, in which there is a tiny pond that, depending on the topography, drains not noticeably to the Sanzenbach. After 1.8 km, the stream flows into the Hellenklingenbach from the right at the level of the first houses in the hamlet of Sanzenbach , which emerges from a forest ridge between the Spitalhalden in the southwest and the communal forest in the south and initially runs through a 0.3 hectare pond at the corridor boundary. Here the Sanzenbach already flows in a small but clear basin at the foot of the hamlet of the same name and 100 meters later takes a shorter tributary this time from the left from the Büschelwiesen .

After 2.2 km it runs under the K 2593, which runs from the hamlet of Sanzenbach to Bibersfeld in the northeast; here are a few houses of the settlement in the Mulde and to the left of the run. A hundred meters after that, an inconspicuous body of water drains from the right into the Sanzenbach, which arises on the northern edge of the community forest and has previously touched the site of the former moated castle Sanzenbach on the low land terrace above the Sanzenbach-Mulde; However, depending on the situation, it must have supplied the water, from which wet zones have been preserved on the south and west edges of the castle stable. 2.7 km below the source there is another 0.1 hectare pond to the right of the stream, which now runs in a much deeper hollow. After he himself has passed an Aussiedlerhof on the left slope, the Langwiesenbach flows into him after a total of 3.1 km from this side . After a total of 3.6 km, the Sanzenbach enters between old quarries on the right and left mouth spur and also opposite in a valley in the uppermost shell limestone and pours into it shortly before the Riedener Bad from the left at a pedestrian ford in its creek bed at about 247  m above sea level. NN in the beavers.

Catchment area

The Sanzenbach drains an area of ​​4.5 square kilometers west of its lower reaches into the Bibers. The greater part of it lies in the slightly hilly landscape of the rose garden , the smaller part on the layered slope in the west and south up to the Mainhardt Forest . The first is in the open field, there is mostly forest on the ascent.

The western tip of the catchment area lies on the Hartäcker hill on the eastern edge of the plateau around Sittenhardt, which drains in the northern part via the Sittenhardter Bach and the Rötenbach to the Fichtenberger Rot . From here the watershed runs in an east-northeast direction over the promontory of the Büschelberg down into the hill country and to the confluence with the Bibers at its eastern tip. The otherworldly competitor here is the roughly parallel Bibers tributary Sülzbach . From the mouth the watershed runs to the southwest over the Sanzenbacher level and then between the hillside forests of Bülz and the community forest on the steep layered slope up to the western Lichten Platte . Here the outlying area drains via the smaller thatched roof, which is also parallel to the lower Sanzenbach, also to the Bibers. At the top of the plateau, the border of the catchment area runs in a slight curve to the west and then to the north-west approximately on the route of the connecting road between Sanzenbach and Sittenhardt back to the Hartäckern . Other competitors on this route are first the largest beaver tributary Dendelbach and then on the longer stretch the Söllbach, which in turn drains to Fichtenberger Rot .

The settlement in the catchment area is low and avoids the proximity of the brook bank. In addition to the village of Sanzenbach with three or four individually standing, nameless courtyards in the outside area, there is only the Zimmerhaus residential area. Apart from a small snippet of the Bibersfeld district of Schwäbisch Hall in the west, the entire catchment area belongs to the municipality of Rosengarten , which also includes all settlement areas.

The mouth of the Sanzenbach 3.6 km below its source above the Riedener Bad from the right into the Bibers .

geology

The Sanzenbach arises in the transition area between the reed sandstone ( Stuttgart formation ) and the gypsum keuper ( Grabfeld formation ) below. The stream reaches the Lettenkeuper ( Erfurt formation ) at its eastern bend , in which it then runs until shortly before the mouth. In the valley floor there are boggy soils . The cone into the Biberstal is cut into the Upper Muschelkalk .

Its catchment area begins at the edge of the silica sandstone plateaus ( Hassberge Formation ) east of Sittenhardt or in the south on the Lichten Platte . Under a narrow edge of the steep slope in the Lower Bunter Marl ( Steigerwald Formation ) there is only one point in the west of a strip of reed sandstone of noticeable width. On the Mittelkeuperhang in the south up to the silica sandstone there is widespread block debris. Loess is located on the ridge between the Unterlauf and the Riedach on the right .

history

On the northern edge of the Lichten Platte , next to a farm road heading west from the Beilberg, just before a fork is the overgrown heap of rubble of the former Sanzenbacher Landturm der Haller Landheeg . A section of the Heeg, coming from the Dendelbachtal, ran above the Spitalhalden and the Geißklinge to the west and later to the north, roughly along the eaves of the Mainhardt Forest.

In the hospital dumps , some abandoned ravines are steeper than today's road with its serpentine up the rather loamy slope, today they are largely impassable due to overgrowth and debris.

Landscape image

The landscape surrounding the Sanzenbach is of course divided into the hillside forest in the south and west of the catchment area, which takes up a little more than a third of its total area, and the hilly rose garden landscape at its feet. The latter consists on the one hand of grassland, which also takes up large areas outside the narrow valley basin in the flatter areas, and on the other hand of fields, which in some places also extend down to the banks of the stream.

There are a number of protected biotopes on the Sanzenbach and its surroundings. Many are wetlands, such as the natural surroundings of the small stream that flows into the Sanzenbach from the right from the Birkach ; the small pond in a forest blade on the eastern slope of the Büschelberg ; the pond at the east bend of the stream, lined with a strip of wood, in which there is reed; a wet meadow in a clearing on the slope in the south between the Waldsteige to Sittenhardt and the Hellenklingenbach ; an accompanying strip of wood after the forest exit of the Hellenklingenbach itself; a wetland to the south and west of the former moated castle; and a near-natural section at the mouth of the Langwiesenbach with wood. The Sanzenbach itself mostly runs in a straight V-ditch below the hamlet, where a tree or bush rarely stands.

In addition to the ravine section in continuation of the Kiesbergweg from the hamlet to the water reservoir in the community forest , there are also protected field trees in other places: North of the Spitalhalden , a wood spike protrudes into the Birkach corridor , from which the aforementioned small stream flows. On the eastern edge of the hamlet, close to the "Wasserschlossbach", there is another field hedge and to the left of the lowest course, a strip of hedge stretches from the tributary of the Langwiesenbach to almost the mouth of the very pronounced upper slope bend and separates farmland above from the grazed slope below. In the lower half of this section of the stream another and wider strip of hedges runs to the left of the stream in the hollow.

The entire catchment area up to the Bibers is part of the Swabian-Franconian Forest Nature Park.
