The Heggraben is a right tributary of the lower Hambach after the Unterhambacher Mühle in the urban area of Gunzenhausen in the Weißenburg-Gunzenhausen district . The course of the stream, which still rises in the Central Franconian district of Ansbach, is around three and a half kilometers long and runs approximately eastwards.
geography
course
The Heggraben rises east of Kleinlellenfeld in the Gewann Letten on the edge of the Cronheim Forest at an altitude of about 465 m above sea level. NN . The stream first flows next to a narrow tube along the northern edge of this forest and then crosses other forests in two smaller sections one after the other. Then it flows through a wide open landscape on its lower reaches to the mouth . It crosses under the district road WUG 24 . The Heggraben flows after a run of around 3.5 kilometers at an altitude of 420 m above sea level. NN southeast of Unterhambach and the Unterhambacher Mühle from the right into the Hambach. The course of the Heggraben has an average bottom slope of about 13 ‰.
Catchment area
The approximately 3.2 km² catchment area is located with the western part in the sub-area Hahnenkamm-Liasgürtel of the natural area foreland of the Southern Franconian Jura , with the eastern part in the sub-area Ornbau-Gunzenhäuser Altmühltal of the Central Franconian Basin . It has roughly the shape of a long, consistently thick tube, always less than a kilometer wide, which extends almost four kilometers from the Kleinlellenfeld area east to the mouth. The with about 503 m above sea level. NN highest point in it is south of Kleinlellenfeld on a small plateau.
The route of the Limes roughly follows the ridge of the ridge on the left that accompanies the little deep valley, behind it the Zochagraben competes with the Hambach a little further up in Unterhambach . Beyond the southern border, in the lower reaches of the Filchenharder Graben runs to the Wurmbach , further to the west in the Cronheimer Wald the catchment area of the Kröttenbach borders, which drains via the Arrabach and the Lentersheimer Mühlbach to the Wörnitz . Two smaller bodies of water to the west of the catchment area also feed this Wörnitz tributary via the Dennenloher See and its outlet.
Around half of the catchment area is forested, while the open fields are dominated by agriculture. Part of Kleinlellenfeld is in the catchment area that is otherwise completely uninhabited.
