The Wolfsbach is an orographically right tributary of the Vilicher Bach in Bonn and Sankt Augustin , North Rhine-Westphalia . It has a length of 3.5 km, its catchment area covers 1.3 km².

course

The source of the Wolfsbach is located in the Holzlar district of Gielgen within the 13 hectare nature reserve Wolfsbachtal . From there, the water flows off in a north-westerly direction and, after leaving the protected area, enters the urban area of ​​Sankt Augustin, where it passes the Hangelar district . In Hangelar the watercourse bends in a south-westerly direction, runs for around 700 meters along the federal highway 56 and finally flows into the Vilicher Bach on the right at Pützchen-Bechlinghoven again in Bonn .

The Wolfsbach overcomes a height difference of 87 meters during its flow path, resulting in an average bed gradient of 24.9 ‰.

Characteristic

Within the protected area of ​​the Wolfsbachtal, the watercourse has a meandering and natural structure and enables rare plant communities to settle there . The water quality report 2002 determines water quality class II for this section and therefore only moderate pollution. The lower course of the Wolfsbach, on the other hand, is in a straightened and only slightly near-natural state; In the area of ​​the B 56, the Wolfsbach runs like a canal through a concrete bed. The normal flow rate of the body of water is 3–18 liters per second, but can reach a maximum of 1,024 l / s during floods.
