geography

course

The Schwalbenbach rises between Hagau, still in Swabia , in the east and Polsingen in the west, at an altitude of 496  m above sea level. NHN in the limestone hillside forest of Polsingen. The stream flows mostly canalised and with only small changes of direction in a west-north-westerly direction. Even before the local border of Polsingen he feeds the local natural pool . Within the parish village, the river flows canalised parallel to Schwalbenbachstraße a little south of the Polsingen moated castle . Then it crosses the state road 2384, which runs through the village, and flows from the left on the western edge of the village and below the church village Trendel, which is opposite and also at the height, at about 437  m above sea level. NHN in the Rohrach. The Schwalbenbach is around 2.1 kilometers long.

Catchment area

The approximately 2.9 km² catchment area, in terms of natural space , belongs with its eastern and middle part to the lower area of ​​the Döckinger plateau of the southern Franconian Alb , with the western part near the mouth to the sub-area of Oettinger Riesvorhöhen of the foreland of the southern Franconian Alb . The greatest height is in a bulge in the catchment area southeast of Hagau near the water reservoir on the Wemdinger Berg and reaches 586  m above sea level. NHN , while the second largest Hipfel Döttinger Berg closer to Polsingen is only 562  m above sea level. Reached NHN . The north-western watershed between Döttinger and Wemdinger Berg drains over the Westenbrunnenbach and the Möhrenbach to the Altmühl , while behind the subsequent southern watershed the area feeds the Riedbach for a long time, which flows into the Wörnitz below the Rohrach , then the Rohrach below the Schwalbenbach , closer to the mouth, via the Federwiesgraben as well as another small Rohrach tributary near the mouth. To the north and upstream of the Schwalbenbach, where the Albtrauf moves closer to the course of the Rohrach, the Rohrach has not had a left tributary for a long time.

Tributaries

The Schwalbenbach flows on the western edge of the settlement of Polsingen against the Rohrach an approximately 1.1 km long tributary stream with a 0.7 km² sub-catchment area. It arises a little east of the castle, first flows northwest on the outskirts to the row of houses around the St 2384, there goes into a hollow and in this follows the street on the Rohrach side to its mouth only about a hundred meters before that of the Schwalbenbach.
