The Saulbach is a 2 km long right tributary of the Erms in the district of Reutlingen in Baden-Württemberg , which flows between Dettingen an der Erms and the Neuhausen an der Erms district of Metzingen from the right and about north.

geography

course

The highest source of the Saulbach is about 480  m above sea level. NHN on the west side and under the L 1241 opposite the outskirts of the village of Kappishäuser in the municipality of Neuffen in the Esslingen district . First it flows almost half a kilometer west in a ridge into the forest, absorbs two small tributaries from the right and then turns around at the border between Neuffen and the city of Metzingen in the Reutlingen district on a very steady southern course. First further in the Hofwald it takes in further tributaries from Seitenklingen, then outside in a tree-rich open corridor, soon one after the other, the Gelbenhäldlesbach from the right, the Spadelbach from the left, the Sackbach from the right and finally a creek from the left from the Rössleshalde , all less than a kilometer are long. Then it crosses under the Ermstalbahn , ends its course on the flat right slope of the river and then flows out at about 372  m above sea level. NHN from the right into the middle Erms .

The Saulbach flows after a 2.3 km long run with an average bed gradient of about 48 ‰ about 108 meters in altitude below its top source.

Catchment area

The catchment area of ​​the Saulbach is 1.9 km² and, in terms of natural space , is almost entirely in the sub-area of ​​the Neuffen-Vorberge of the Middle Alb foreland ; only a small gusset in its north-east corner just extends to the south-western side summit of the Jusi spur of the Middle Kuppenalb , where the 642.5  m above sea level. NHN is the highest point.

The catchment areas of the following neighboring waters are adjacent in turn:

  • In the north lies the headwaters of the Autmut , which flows into the Neckar after the Erms ;
  • in the east, near the Nitzenbach, it flows a little parallel to the Erms;
  • the area beyond the western watershed is predominantly drained by the Spalerbach to the downstream Erms;
  • in the northwest, a tributary of the Lindenbach , an even deeper tributary of the Erms, competes .

One with only 510.3  m above sea level. NHN significantly smaller height achieved the Hofbühl the southwest corner of the basin above the Ermstal. Like its bigger brother Jusi, this hilltop is a volcanic hardy from the time of the Swabian volcano in the Miocene , the core of which is a solidified volcanic vent. Apart from the volcanic basalts, which have been identified or suspected there and in a few other places, there are mostly layers of the Brown Jurassic in the catchment area . From the lower Jusihang down through the village of Kappishäuser, Ornatenton-Formation , Dentalienton-Formation , Hamitenton-Formation and Ostreenkalk-Formation follow in quick succession , in the border area of which the uppermost spring is to the underlying Wedelsandstein-Formation , few other sources in the Wedelsandstein itself Most of the course and almost all of its tributaries lie in the even deeper Achdorf formation , which is found in most of the catchment area. On the flat lower river slope and in the Ermstalgrund there are terrace sediments of the river, overlaid over a large area by Holocene washoff masses.

The upper catchment area is in the Kappishäuser district of Neuffen in the Esslingen district , the lower in the Reutlingen district , predominantly in the Neuhausen an der Erms district of Metzingen , and to a lesser extent in the Dettingen an der Erms district . After the district boundary, the stream first flows through a larger piece of Neuhausener, then a smaller piece of Dettinger district and is finally Grenzbach between the two. The only settlement in the catchment area is the village of Kappishäuser.

  • (About a dozen blades inflows), from left to right at about 495- 405  m above sea level. NHN in its northern continuation in the Kappishäuserner district and then in the Hofwald , all under 0.4 km. Most of the springs are located at an altitude of around 450  m above sea level. NHN and often near the edge of the forest to the corridor.
  • Gelbenhäldlesbach , from the right and west to about 395  m above sea level. NHN across from the southern tip of the Hofwald , 0.4 km and less than 0.2 km². Arises at about 435  m above sea level. NHN and delimits the hillside corridor Gelbenhäldlesbach in the south.
  • Sackbach , 0.3 km and approx. 0.1 km². Arises below 420  m above sea level. NHN near some large stables on the east-south-east slope of the Hofbühl
  • Spadelbach , from the left and northeast to 387.7  m above sea level. NHN less than a hundred meters after the previous one under the northern Rössleshalde , 0.8 km and approx. 0.3 km². Arises at about 470  m above sea level. NHN in the long fields south of Kappis houses.
  • (Bach from the Rössleshalde ), from the left and east to about 385  m above sea level. NHN even before the foot of the farm road from the stables mentioned, over 0.2 km and under 0.1 km². Arises at about 420  m above sea level. NHN on the Rössleshalde .

Mouth of the Saulbach from the right and north to about 372  m above sea level. NHN on the municipality boundary Dettingen an der Erms to the district mark of Metzingen - Neuhausen an der Erms in the middle Erms . The Saulbach is 2.3 km long and has a 1.9 km² catchment area.

Flood protection

To improve flood protection, the creek passage below the Ermstalbahn was enlarged and the creek renatured.
