The Hambach is a creek about 8.3 kilometers long in the Central Franconian districts of Weißenburg-Gunzenhausen and Ansbach , which flows into the Wurmbach from the left and west near Unterwurmbach .

geography

course

The Hambach rises in the forest area Unterer Wald from the Buchbrunnen (source name), which is about a kilometer southeast of the center of Arberg in the community-free area Unterer Wald. From here on, the Hambach flows very steadily in an east-south-east to south-east direction. After about two kilometers (as the crow flies), it emerges from the forest east of Goldbühl , after which it moves in a meandering course through a very flat valley in which it divides Oberhambach , touches Unterhambach and passes the Unterhambacher Mühle . For its last 300 meters, it bends to the northeast and then flows a little west of Unterwurmbach at the edge of the L 466 from the left into the Wurmbach approaching in the north , which at the inflow then changes almost to the last direction of the Hambach.

On its fairly constant east-south-east to south-east path, the Hambach feeds several smaller ponds, especially at the inlet of the Grundgraben and at Unterhambach.

Catchment area

The Hambach has a catchment area of ​​almost 21 km². It has roughly the shape of a triangle with a west-northwest corner on the summit of the Eichelberg between Arberg and Kemnathen, on the summit of which less than half a kilometer west of the source also at 522  m above sea level. NN the greatest height in the catchment area is reached. The east-south-east point is at the mouth, the third, obtuse-angled corner southeast of Kleinlellenfeld on a hill crowned with a radio mast.

Beyond the long northeastern watershed lies the Altmühl catchment area and insignificant tributaries from it. In the southeast, the Wurmbach running to the Altmühl and absorbing the Hambach itself competes mostly over the Filchenharder Graben . In the rest of the south, as on the entire west side, the Lentersheimer Mühlbach running to Wörnitz drains the adjoining area, into which the Cronheimer Kröttenbach flows initially in the south , while the direct competitors west of the watershed absorb its large inflow, Schwaninger Mühlbach, from the left. In the northwest there is a short catchment area on the other side of the Wieseth , which in turn flows to the Altmühl.

From a natural perspective, the uppermost catchment area lies in the sub-area Hahnenkamm-Liasgürtel of the foreland of the southern Franconian Jura , the entire rest in the sub-area Dinkelsbühler hill country of the Central Franconian basin .
