geography
course
It rises in Höntrop near the suburb of Eppendorf not far from the street "Am Ahbach". Initially in a north-easterly direction, it flows along a forest through the fields of the Krummen Ecke to Engelburg as an open stream. It is piped on under the Wattenscheid-Bochum Hbf railway line, re-emerging at the tennis halls and running along the Sauren Wiese until it is again led underground behind Essener Straße. In a wide arc north rotationally it is under the Thyssen Krupp - plant Höntrop forwarded until it appears after the A 40 as a channel back to the surface. A few meters afterwards, at the height of the Bochum-West motorway triangle , it flows into the Kabeisemannsbach , which is also canalized and later flows into the Goldhammer Bach . This flows into the Hüller Bach , which empties into the Emscher.
The upper reaches of the Ahbach (in the area of the former Marianne colliery ) no longer has any springs. The dry weather runoff begins a little behind the lane opening in the Saure Wiese area, a little below the tennis club, through an attached former hereditary tunnel.

Renaturation
The stream was renatured in its lower reaches in 2009 as part of the project for the reconstruction of the Emscher system , as was the Saure Wiese area crossed by the stream. The costs for a sewer amounted to 15 million euros, the redesign of the stream was 9 million euros.
In the renatured area along the Am Ahbach road , among other things, the yellow juggler flower grows naturalized .
