geography
course
The Agbach rises in its valley basin on the eastern edge of Herrnsberg, which is about one kilometer long and about 40 meters deep, opposite the plateau, from two sources whose outflows quickly merge. In an increasingly dug-out valley, it flows under forest on the slopes in south-east to south-west directions. In the Untertal, it passes a long, newer part of the Gredings settlement on the left bank, passing Hintermühle , Lanzmühle , Mittelmühle and Vordermühle . At the Kripferturm in the old town, the Agbach divides into two branches. The western one flows through the tower and the old town of Greding to the Blasiturm, where it leaves again, the eastern one, on the other hand, flows in an arc outside the town wall around the old town, and then flows back again at the Blasiturm; it was created to keep floods away from the city. About two hundred meters further on, the reunited Agbach flows into the Schwarzach from the left at the footbridge to the Achmühle opposite .
After a 5.1 km long path with an average bed gradient of 19 ‰, the Agbach flows about 96 meters below its source.
Catchment area
The surface catchment area of the Agbach is 15.4 km². Its highest point on the north-eastern edge near the village of Österberg in Greding is about 563 m above sea level. NHN . From a natural spatial point of view, the area belongs largely to the sub-area Western Sulzplatte of the northern part of the Southern Franconian Jura and, with the small part near the mouth, to the lower area of the Schwarzach-Thalach valley funnel of the Altmühlalb .
It borders in turn on the catchment areas of the following neighboring waters:
- behind the short north-western border at Österberg drain the Kreuzfeldbach , another tributary at Obermässing and the moat near the Rotheneichmühle far above Greding zur Schwarzach ;
- the long north-eastern watershed runs to the trout stream , initially called Rothengraben , which flows into a remnant part of the Sulz , a tributary of the Altmühl , which also receives the Schwarzach ;
- in the southeast flowing thistle millstream right after and after Agbach Greding in the Schwarzach
- on the south-west side the Hirlbach , the Kuhbach and the Schmiedackerbach drain one after the other and upstream to the Schwarzach.
The course of the brook belongs entirely, the catchment area mainly to the town of Greding , a fringe of the area in the northeast in and on the mountain forest of Buch to the town of Berching , and an even smaller one on the eastern edge to the town of Beilngries .
