The Aurach is a year-round flowing water of the 2nd and 3rd order in the Lower Franconian district of Haßberge in northern Bavaria . It is a left 9.5 km long, north-northeast and left tributary of the Nassach .

geography

course

The 9.5 km long Aurach arises north of Eichelsdorf from the confluence of two source streams . These arise from karst springs on the southern flank of the Haßberge in the Rottensteiner Forest. From there it flows largely in a southerly direction, past the southeastern edge of the city of Hofheim , crosses under the B 303 to the northwestern edge of Ostheim . There the river swings in a south-westerly direction and flows from the left into the Nassach, a tributary of the Main , on the northern outskirts of Rügheim .

The sources are in the Haßberge landscape protection area, the further course of the river is in the NSG Geißleraue and Aurachwiesen near Ostheim of the Natura 2000 project.

There, near the northernmost point in the area of ​​the Schwedenschanze , is at 487  m above sea level. NHN highest point. The western watershed mostly runs much deeper, towards Nassach, which receives the Aurach near the southwestern tip of its catchment area. The entire catchment area is in the area of ​​the municipality of Hofheim in Lower Franconia .
