The Seitenbach is a 9-10 km long, approximately east-north-east flowing brook in the district of Böblingen in central Baden-Württemberg , which flows from the left into the middle Aich in the town of Waldenbuch .
Surname
The Seitenbach has different names on its sections. The uppermost waterway name that can be found on the maps is Totenbach , which is used at least for the section between Weil im Schönbuch and the associated Totenmühle, probably even to a little below the Segelbach (!) Flood retention basin that soon follows it up to the inlet of the Reishaldenbach; It remains to be seen whether the stream previously in and also in front of Weil on its right source branch bears a different name.
The Totenbach section is followed by the Segelbach section in the forest, presumably to the tributary of the Greutbach. Only then, on the last less than one and a half kilometers through the remaining forest and the settlement area of the city of Waldenbuch, is the brook Seitenbach called.
In the following, the official line name Seitenbach is used uniformly .
geography
course
The Seitenbach flows about 300 meters northeast of the Holzgerlinger Domain Schaichhof at about 495 m above sea level. NHN on the other side of the B 464 already on the ground of the neighboring community of Weil im Schönbuch the approximately one quarter hectare large Schaichhofsee in a north-northeast direction and immediately runs along a newer settlement of Weil. Soon he enters the building area of the municipality in the area of a commercial zone. In it, the Seitenbach crosses under the Schönbuchbahn, close to its Weil im Schönbuch-Troppel stop, and on the other side from the left and west-northwest, the Lachentalbach , its other spring brook, which slightly exceeds it in terms of length, catchment area and source height.
In the same direction, however, it runs through the elongated village of Weil between the town center on the right and the newer settlement areas on the left, and passes another quarter-hectare-sized lake on Seestrasse. Already a little before the last houses in Weil it flows open and accompanied by wood with ever stronger short changes of direction about eastward in a meadow-shaped hollow, past the town's sewage treatment plant and later the Totenbachmühle almost 100 meters to the left of the course, whose formerly open mill canal is today no longer exists and where the forest begins on this side of the stream. Immediately after this it flows through the 1.1 ha large flood retention basin Segelbach , with the dam also crosses the L 1050 leading from Weil to Waldenbuch and then runs longer through a forest area that extends from the upper Aich in the north over the ridge of the Weiler Berg (up to 438.2 m above sea level ) to the left of the Seitenbach up over it and up to the rice heap on the slope of the Horn on the right ( 479.1 m above sea level ).
Immediately after entering the forest, the Reishaldenbach, which mostly still runs in the open corridor, flows in from the southwest, a little after which the stream, which then flows in a narrow meadow, turns back to east-northeast. Right lead from the hillside forest four more, short and usually only unstable water-carrying blades brooks. The next larger tributary, Greutbach, from the south-south-west, on the other hand, has a valley on the middle and lower reaches, it flows into a lonely property.
About half a kilometer further down the valley, the forest breaks out on the right slope, the stream reaches the outskirts of the small town of Waldenbuch and the forest also ends on the left slope. At the end of the sack of the street Im Seitenbach, a mill canal goes off to the left, which leads through the town to a canal that also runs to the right of the Aich. A little after the stream has crossed Tübinger Strasse (L 1208), it also disappears underground and then takes on the previously mentioned covered Aich side canal from the left under Bahnhofstrasse, here already on the east side. In its last few meters, Immenbach, which will soon be ruined in the urban area, flows into it from the south . Then the Seitenbach flows across from the fire department store in Bahnhofstraße from the right and at about 343 m above sea level. NHN into the Aich, which ends its north loop around the Waldenbuch city center and then continues eastwards .
The Seitenbach flows after its 9.4 km long course with an average bed gradient of around 16 ‰ about 152 meters below its origin in the Schaichhofsee.
Catchment area
The Seitenbach has a catchment area of 12.6 km², which naturally lies around the upper and middle reaches in the lower area of the Holzgerlinger Platte and around the lower reaches in the lower area of the Nördlicher Schönbuch of the Schönbuch . His at 518.3 m above sea level. NHN reaches the highest point at its western tip just in the area of the municipality of Altdorf on the summit of the field hill Hohloh , which overlooks the origin of the longer left upper course Lachentalgraben in the area of the town of Holzgerlingen .
A large part of the catchment area on both sides of the upper and middle runners belongs to the municipality of Weil im Schönbuch , with the exception of the already mentioned peripheral gussets of Altdorf and Holzgerlingen in the west and also a peripheral gusset of Dettenhausen in the south. There is almost no forest in this entire area and, in addition to fields, there is a large proportion of settlements. To the east of this, beyond the natural boundary to Schönbach, begins the closed forest and the area of the city of Waldenbuch , about as large as that of Weil and in its lower half again dominated by open fields and settlement areas.
The catchment areas of the following neighboring water bodies border on that of the Seitenbach, which, with the exception of one, are also tributaries of the Seitenbach receiving stream Aich :
- In the northwest the Eschelbach flows as the first significant tributary to this;
- in the north the Aischbach drains to her;
- in the northeast of the Fäulbach ;
- in the east the Brunnenbach ;
- beyond the entire southern border, the runoff reaches the largest Aich tributary, the Sheikh, partly via its left tributaries . This flows - in the southwest often very close, in the southeast rather far away - in about the same direction as the Seitenbach.
- Only in the west borders the catchment area of the Erlesgraben for a short section , a tributary of the right upper reaches Altdorfer Würm of the Würm , which flows over the Nagold and the Enz far down the Aich into their receiving water Neckar ; this section of the total watershed across the Hohloh is hydrologically the most important.

geology
Geologically, the catchment area shows a clear dichotomy. The Black Jura of the Holtgerlinger Platte lies in the west as well as in the central part on the heights surrounding the valley, while the Keuper of the Northern Schönbuch lies in the east, near the mouth . The two source brooks that merge in Weil run in strips of Holocene runoff masses, around which loess sediment (loess loam) from Quaternary deposits is superimposed on the Black Jurassic. From the center of Weil im Schönenbuch is then available in the basin the Angulatensandstein formation of the black Jura, the same in the area of the lake Psilonotenton formation follows. A little after the end of the village, the third hollow wedge of the tuber marl ( Trossingen formation ) begins , which further and further deviates from the valley floor, on which Holocene floodpillings now lie on the left as far as the Segelbach flood retention basin. Earlier on the left side of the basin the Stubensandstein ( Löwenstein formation ) sets in , above which the marl ends at the top, while on the right slope of the valley there is still long loess sediment under the marl layers on this side of the ridge down to the run. From the Greutbach inflow, the Stubensandstein dominates on the right, the floodplain clay band surrounding the stream merges into the wider band on the right of the Aich in Waldenbuch.
Nature and protected areas
From its origin at the Schaichsee until shortly after Weil, the Seitenbach is classified as rich in coarse material , then as a carbonate low mountain stream rich in fine material up to its mouth . A gallery forest accompanies it from the lower settlement boundary from Weil to the Segelbach retention basin on its winding course, which is very close to nature. From there, the stream bed has gravelly to sandy sediment and shows some pools in the course. After the reservoir, the bed is two to six meters wide and mainly accompanied by black alder and ash. One of the spring streams from the right slope forest running into this area has formed tufa limestone steps.
The majority of the lower catchment area is in landscape protection areas . The Glemswald conservation area begins below Weil in the valley basin, which then expands to the ridge heights on both sides. At the municipal boundary from Weil to the town of Waldenbuch on the lower Reishaldenbach, it meets the nature reserve Waldenbuch / Steinenbronn , which from there encompasses the area on the right side of the Seitenbach up to the settlement boundary of Waldenbuch.
