# Starzel (Neckar)

Starzel is a river of Baden-Württemberg, Germany. It is a right tributary of the Neckar west of Rottenburg am Neckar.

## Geography
### Course

Starzel is being built directly at Albtrauf at the European watershed, about three kilometres south of Hausen im Killertal. (a district of Burladingen), a few dozen meters north of the hamlet Neuweiler, which belongs to Albstadt.
For historical reasons, the valley created by the Starzel, about 14 kilometres long on the northern edge of the Swabian Alb from its source to Hechingen is called Killer Valley. It is named after the village Killer, whose parish was responsible for the whole valley. The name Killer is historically composed of church and hamlet.
Near Hechingen the Starzel is fed on the left side by the Reichenbach. It now flows more to the west and is then at Stauffenburger Hof again strengthened from the left side by its longest tributary, the Zimmerbach.
After the passage of Rangendingen it turns to the north and finally flows into Bieringen at a height of 354 m above sea level, from the right into the Neckar.

## Geology and geomorphology

near Hechingen-Stein with border outcrop between Jura and Keuper]
From the White Jurassic to the Muschelkalk the Starzel passes through all layers of the Jurassic and about two thirds of the Triassic. Its valley was formed by retrograde Erosion, in that the stream from the northwest cut deeper and deeper into the strata of the Swabian Alb and its foreland. The valley of the Starzel river intervenes eleven kilometres into the plateau of the Swabian Alb and is bordered in the west by the 957 high Raichberg and in the east by the up to 840 meter high hayfield. It begins with the source area of the Starzel and its tributaries at the watershed between the river system of the Rhine and that of the Danube. A special feature are the so-called waterfall layers, a hard sandstone, which is bedded over leafy shale clays. Between Jungingen and Schlatt the Starzel has formed an eight meter high waterfall, the Junginger Gieß. For long stretches it moves in a near-natural stream bed. Between Jungingen and Hechingen it has deepened like a canyon.

## Starzel flood 2008

In the evening of 2 June 2008, a thunderstorm caused heavy rainfall and flooding, as a result of which three women drowned, two in Jungingen and one in Hechingen. The "Killer valley" made international headlines like this. Around 3.4 million euros have been paid out to those affected to repair the material damage (1.5 million from donations, 1.8 million from the state of Baden-Württemberg). Thus, the entire notified need has been covered.
As a result of the disaster, the Zweckverband Hochwasserschutz Starzeltal was founded in 2013.
