The Wurmbach is an almost 13 km long brook in the central Franconian district of Weißenburg-Gunzenhausen in Bavaria , which flows into the middle Altmühl opposite Gunzenhausen from the left and south-southwest .

geography

course

The Wurmbach rises about 1.8 km north-northwest of the center of the parish village Ostheim of the Westheim community at about 512  m above sea level. NHN at the northeast foot of the Wachtlerberg ( 587  m above sea level ) and is immediately fed by another left spring. Along federal highway 466 , which he crosses twice under after exiting the forest on a north-east course to the eponymous capital of Markt Gnotzheim , he reaches there and briefly runs under its western tip. Then straight away again in the open, he passes the Letzleinsmühle on the right bank, now flows north between the Galgenberg on the right and the last wasteland Simonsmühle von Gnotzheim on the left and then changes to the town of Gunzenhausen on the right slope just below the hamlet of Steinacker .

At the level of the village of Nordstetten , which lies in the mouth of the tributary valley, it takes up the border ditch from the left opposite the town's sewage treatment plant . Then he runs north-northwest towards the village of Maicha ; On the left edge of the wide floodplain, a floodplain runs alongside paths from Nordstetten. At Maicha, the Wurmbach running at the foot of the right slope bends around the western Wurmbacher Berg to the northeast. Halfway from there to Oberwurmbach , the mentioned left Auenbach runs towards it, which has received a tributary from the slope at Maicha. At Oberwurmbach the Filchenharder Graben flows from the west through the place built on the flat spur and into the tapering valley. Even before the larger Unterwurmbach , the stream reaches the western edge of the B 466 and follows it a little to the north, while it runs under the bridge of the Nördlingen – Gunzenhausen railway line, which is now used as a museum railway . Then, coming from the left and from the north-west, the Hambach, the most important tributary of around 8.5 km in length, flows into it . In the east-north-east course, the Wurmbach then crosses under the B 466, passes Unterwurmbach on its northern edge, reaches the museum railway that has meanwhile been merged with the Treuchtlingen – Würzburg railway line, runs along its dam and crosses under the B 13, which branches off from the other federal road, across from the northwest corner of the Gunzenhausen town center then flows into the Wurmbach at the Altmühlbrücke of the railway after 12.9 km from the right and south-west into the middle Altmühl , which flowed around the Altmühlsee just above .

Catchment area

The Wurmbach runs through the natural areas of the foreland of the southern Franconian Jura (sub-areas Hahnenkamm-Vorberge and Hahnenkamm-Liasgürtel ) and the Central Franconian Basin (sub-areas Dinkelsbühler Hügelland and Ornbau-Gunzenhäuser Altmühltal ). The watershed drains 43.6 square kilometers, which apart from the abovementioned natural areas also the right of the upper reaches one corner of the southern Franconian computing Hahnenkamm belongs, where the with 642.4  m above sea level. NHN is the highest point on the Hahnenkamm-Nordwestsporn Spielberg .

Behind the eastern watershed from the estuary up to this Spielberg lies the downstream catchment area of ​​the Altmühl with its right tributaries down to the Schlangenbach as direct competitors. The catchment areas of the left Wörnitz tributaries, "Westliche" Rohrach in the southeast, Bruckbach in the south and Grundbach in the southwest, border on the rather short southern watershed . The western watershed is the longest, the runoff on the other side ultimately also reaches the Wörnitz via the Lentersheimer Mühlbach . To the north of the Wurmbach catchment area, the Altmühl feeder and the Altmühlsee , which it feeds, are very close to the edge of which the Walder Altmühl leads not only seepage water from the lake but also the water of smaller tributaries from the watershed to the Altmühl.

  • Funkenhardgraben , from the left and west to about 472  m above sea level. NHN a good 200 meters after the previous one, approx. 2.0 km and approx. 1.3 km². Rises at about 519  m above sea level. NHN on the lower northern slope of the Wachtlerberg .
  • Grenzgraben , from the left and southwest to about 433  m above sea level. NHN near Nordstetten , approx. 2.6 km and approx. 4.7 km². Arises at about 466  m above sea level. NHN southwest of Nordstetten just beyond the city limits in the Gewann Hoffeld of the Wassertrüdinger parish village of Obermögersheim .
  • Filchenharder Graben , from the left and west to about 420  m above sea level. NHN near Oberwurmbach , approx. 3.2 km and approx. 2.5 km². Arises at approx. 439  m above sea level. NHN a little west of Filchenhard .
  • Hambach , from the left and from the northwest to about 418  m above sea level. NHN on the edge of the B 466 near Unterwurmbach , approx. 8.5 km and approx. 15.4 km². Flows at about 497  m above sea level. NHN the Buchbrunnen on the eastern slope of the Eichelberg near the Arberger village of Kemmathen .

Little Wurmbach

From Unterwurmbach in the flat floodplain, nowhere more than a few hundred meters away in the south does the Kleine Wurmbach, which is emerging on the north-western edge of the village, run roughly parallel to the lower reaches of the Altmühl downstream. It's only about 2.1 km long. From its lower course, a course called Augraben goes off to the right in the Altmühlaue, which after about 1.6 km runs almost parallel to the river shortly before the road bridge of the B 13 flows into a right Altmühl oxbow lake.
