Geography
Course
The Armuthsbach rises about 1.5 km southwest of Tondorf at a height of 531 m above sea level (NHN). Its spring lies on the territory of Blankenheim. Flowing in a mainly easterly direction the Armuthsbach passes through the village of Rohr. Below the settlement the stream reaches the state border with Rhineland-Palatinate. As it continues to its mouth, there are no further villages along its course. About 400 metres north of the stream is Hümmel, about 900 metres south is Wershofen. About 800 metres west of Schuld the Armuthsbach empties into the Ahr from the left at an elevation of 245 m above NHN.
The Armuthsbach flows through the North Rhine-Westphalian nature reserve of the Armuthsbach and Tributaries (Armuthsbach und Nebenbäche).
The stream descends through 286 metres and has an average riverbed gradient of 15.5 ‰. Its catchment area covers 60.526 km² and its waters drain via the Ahr and Rhine into the North Sea.
