The Petersbach is a brook in the Graz districts of St. Peter and Liebenau .
The Petersbach rises in a swamp area at the foot of the Lustbühel and flows southeast towards the Mur , into which it flows north of the Puntigamer Bridge. The most important tributary of the Petersbach is the right feeder from the Paierlhang, which joins at the intersection of Peterstalstraße and Weiherweg .
In addition to the Andritzbach and the Schöckelbach , the Petersbach is the most flood-prone city of Graz. The areas at risk of flooding extend along Peterstalstrasse and Banngrabenweg. One problem area is St. Peter Hauptstrasse , where the Petersbach runs 450 meters below the road. In recent times there have been several major floods because of the bank zone construction with a discharge capacity of only 2 m³ per second - a flood of the century is calculated at 16 m³ per second.
