Lein

The Lein is a river of Baden-Württemberg, Germany. It is a left tributary of the Kocher. Its source is near Kaisersbach. It passes through Welzheim, Täferrot, Leinzell and Heuchlingen, and flows into the Kocher in
Abtsgmünd.

From its source at Kaisersbach–Eulenhof, the river Lein flows quite steadily to the south and in the east past Welzheim. At Alfdorf–Haghof its course bends off to the east and maintains this direction with slight fluctuations until Heuchlingen, from where it reaches Abtsgmünd and the Kocher in northeastern direction. Its catchment area is mainly on its left side, because in its southern upper valley it has a strong competitor on the right side in the nearby Wieslauf and its tributaries with a clearly deeper erosion base, in the eastern middle course to Heuchlingen the Rems tributaries dig the water out of it so much that the watershed follows the Lein itself closely in the south, often only a few hundred meters away from the river itself. Only in the northeast-oriented lower course from Heuchlingen it has any noteworthy right tributaries at all, here it shares the ridge around Dewangen with the Kocher in about equal parts. Its tributary system has roughly the shape of a ridge: In the south and west the Lein itself is situated, from the north the larger tributaries are parallel to it.
