The Sulzbach ( ) is a less than 4 km long creek in the middle of Baden-Württemberg , together with the main left upper course Planklingenbach . The course of the name lies entirely in the district of Böblingen and in the north of Schönbuch , it flows from the left at the Obere Rauhmühle in the municipality of Steinenbronn and roughly northwest into the upper Aich , the above-mentioned upper course in the southern Glemswald also borders the district of Esslingen .
geography
Upper course Planklingenbach
The left main headwaters plan Klingenbach springs on the training area in the east of Böblingen just east of the hill Burnt hump ( 502.3 m above sea level. NHN ) in Won Red Steigle near the outgoing from Musberger way Streitweg to about 485 m above sea level. NHN . It runs its entire length in the forest, initially to the southeast. From the right, he takes in the stream that arises from the drainage of the heaped mountain near the American school complex on the on-site exercise area and is then fed by the Mönchsbrunnen , an almost as long source branch of the Planklingenbach. The Sulzbach (!) Flows further down from the northeast , after which the Planklingenbach runs southwards for a good half of its 1.1 km long remaining course to the confluence of the Kaisereichenbach from about west. After the last stretch from there on again to the southeast, it flows to 401.2 m above sea level. NHN at the southeastern tip of the Böblingen urban area merges with the other upper reaches of the Gehrklingenbach, which finally approaches from the west.
The Planklingenbach is 3.2 km long and drains an approximately 4.9 km², predominantly forested area without any settlement, predominantly in the Glemswald heights. The mouth, reached with a mean bed gradient of about 26 ‰, is about 84 meters below its origin.
Upper course Gehrklingenbach
The right tributary upper course Gehrklingenbach rises in the Gehrenklinge or Gerenklinge a little south of the school complex mentioned at about 468 m above sea level. NHN and runs, also in the forest, on almost half of its way south-east to the inlet of the approximately equally long source branch Ziegenbach from the south-west. From there, a little north of the sports fields on the Schönaicher Eisenhalde , it flows eastwards to the junction with the Planklingenbach.
The Gehrklingenbach is 2.9 km long and drains an area of only 3.0 km². On the left of the course there is almost exclusively forest of the Glemswald-Randhöhen, while on the right there are also large parts in the clearing island around Schönaich and include built-up areas on the Böblinger Roten Kapf , on the northern edge of Schönaich and in particular the industrial area on the Eisenhalde . The Gehrklingenbach flows with a mean bottom gradient of about 23 ‰ only about 67 meters below its origin.
course
The Sulzbach , combined from both upper courses , soon flows southeast and through a valley direction, on the right tree line of which the small Schönaich residential area Sulzbach is located. Towards the end of the open meadow, the Badrainbächle , which tapers from the left, has pushed the course against the right foot of the slope. Immediately before the Sulzbach crosses under the L 1051 Schönaich– Steinenbronn again in the forest, the Klingenbach flows from the last nearby place , where the creek bends towards the south. Still in the valley forest, it crosses a fore-lake quite far in front of this and then the permanently dammed, about half a kilometer long flood retention basin Sulzbach with a normal lake area of almost 4 hectares. Below the lake dam it flows for almost half a kilometer in open valley floodplain and then flows into about 361 m above sea level NHN at the Obere Rauhmühle von Steinenbronn from the left into the upper Aich coming from the west , which then continues south-west.
From the confluence of its upper courses, the Sulzbach is 3.7 km long, together with its main course upper course Planklingenbach 6.9 km long and has a 14.8 km² catchment area. The mean bed gradient between the origin of the Planklingenbach, which is about 124 meters above the mouth, and the Sulzbach mouth is around 18 ‰, for the only 40 meters between the confluence and the mouth it is around 11 ‰.
Catchment area
The Sulzbach has a 14.8 km² catchment area. The northern parts with the two upper reaches and their partial catchment areas are, from a natural spatial point of view, almost completely in the lower area Glemswald-Randhöhen of the Glemswald , the southern in the sub-area Nördlicher Schönbuch des Schönbuchs . The highest point on the heaped mountain in the training area near the northwestern watershed reaches over 540 m above sea level. NHN , the naturally highest point nearby in the Hunnenbühl or Hennenbühl 519.8 m above sea level. NHN .
The streams competing in turn across the watershed are:
- in the north the Mahdenbach , the right upper course of the Reichenbach , which flows significantly deeper than the Sulzbach from the left into the Aich ;
- further right tributaries of the Reichenbach compete in the northeast up to about down to the Leinfelden-Echterdingener Schlösslesmühle ;
- Beyond the southern watershed, streams run from the left to the Aich, smaller ones below the Sulzbach, larger ones above the estuary up to the Krähenbach :
- the area behind the western watershed is drained by the Murkenbach via the stream of water from Schwippe , Würm , Nagold and Enz far below the mouth of the Aich to the Neckar ;
- in the northwest, the left upper course Goldbach takes on the runoff beyond the catchment area border.
The hydrologically most important section of the watershed is therefore on the west and north-west side.
The course of the name of the Sulzbach is, with small deviations on both sides, the border between the communities Schönaich on the right and Steinenbronn on the left. Schönaich also extends right to the lower reaches of the Gehrklingenbach, while the larger upper reaches of Planklingenbach and further up its left tributary Sulzbach separates the town of Böblingen and the training area in the west from the forest area of Leinfelden-Echterdingen in the Esslingen district in the east. The other municipalities with a catchment area are all in the Böblingen district .
Only the small residential areas Sulzbach von Schönaich, shortly after the confluence of the brook and Obere Rauhmühle von Steinenbronn , are located on the course of the Sulzbach or close to it . Also in the catchment area are most of the village of Steinenbronn, the northern edge of Schönaich and part of the Roten Kapf settlement and the development on the training site, including the school center that has recently been built there, both of which belong to Böblingen. The predominant central part of the catchment area is almost closed with forest.

geology
The main part of the catchment area is the Stubensandstein ( Löwenstein Formation ) of the Middle Keuper, which also forms the valleys of Planklingenbach, Gehrklingenbach and Sulzbach, the latter only up to the retention basin on the Unterlauf, where the valley floor meets the Upper Bunten Marl ( Mainhardt Formation) ) of the Mittelkeuper reached. To the left of the valley axis from (its left tributary) Sulzbach, the lower Planklingenbach and lastly the main water Sulzbach rise the heights around the Hohenwart ( 497.6 m above sea level ) over the uppermost Keuperschicht tubers ( Trossingen formation ) into the Black Jura , initially up to the Psilonotenton and Angulate sandstone formation , in the local area of Steinenbronn there is even the Arietenkalk formation at the top . On the eastward sloping slopes to this valley axis ( leeward position of the westerly winds) lies a mostly narrow strip of loess sediment from Quaternary deposits.
The catchment area is parallel of two, up to half a kilometer wide tectonic trenches crisscrossed from northwest to southeast, ie in the rough direction of Plan Klingenbach and Sulzbach. The northeastern one enters the area between the hollows of the Planklingenbach and its first left tributary past the Mönchsbrunnen and ends on the left side of the Planklingenbach in the area of the Hohenwart ridge. On top of its deep floe there are mostly layers of the Black Jurassic, here even up to the Obtususton formation . The second ditch begins at a transverse fault to the right of the lower Gehrklingenbach and runs a little to the right and parallel to the upper half of the Sulzbach, crosses its Untertal before the retention basin and then continues beyond through the southern local area of Steinenbronn; In the last section, there are also subjurassic layers in part, while these were previously mostly covered by the loess deposits mentioned on the left side of the Sulzbach.
On the western edge of Steinenbronn, the Sulzbach tributary Klingenbach runs in a blade crack, where the Oberkeuper layer of the Exter formation in the upper stream bed is also exposed above the marl . In the catchment area this occurs at best as a narrow band between Mittelkeuper and Jura.
Nature and protected areas
The forest in the catchment area, minus the large training area and with additional small peripheral zones, is part of the Glemswald landscape protection area that extends over both districts . Large parts of the left valley slope between the upper course confluence and the southern bend of the Sulzbach belong to a forest protection area.
The stream, which is close to nature in parts, is 2–3 meters wide, at widenings even up to 5 meters wide. Planklingenbach and the following Sulzbach are carbonate low mountain streams rich in fine material, the substrate of which is stony to muddy. There are sandbanks in the partly steeply dug-in stream, which sometimes falls over small garbage into pools, while elsewhere the bed is gravel. The banks are sometimes boggy, the floodplain often swampy, stratified springs emerge on the slopes. The flowing side streams have partly deposited wide alluvial cones.
