geography

Spring streams

Confluence of Hügelsbach (back left) and Sangenbach (back right) to Altenbach

Hügelsbach

The Hügelsbach rises south of Aschaffenburg- Schweinheim near the barbecue area on Ebersbacher Straße. The source area is still a restricted area due to the risk of detonation and is only grazed by sheep. The Hügelsbach runs in a southerly direction and is reinforced from the right by the outflow from the Breitenbrunnen. The Hügelsbach is about 1 km long, the shorter, but much richer spring stream.

Sangenbach

The source of the 2.8 km long Sangenbach, also called Reichenbach , is located south of Gailbach between the mountains Spießknückel (358 m) and Stengerts (347 m). It runs through the Viehruhgraben and receives the inflow from the Goldgraben, which rises from the Reichenbacherbrunnen. From here the Sangenbach runs through the Lichten Sanggraben and reaches the former military restricted area. It fills the artificially created sand lake above Ebersbacher Straße and unites at the lower end of the Honiggrund in the approximately 14 hectare Altenbachgrund nature reserve .

course

Shortly after the confluence of the source streams, the Altenbach is additionally reinforced by the Elbertsbrunnen . This spring was taken in 1935 by the Obernau and Schweinheim hiking clubs . The Altenbach runs in a southerly direction and runs in a south-west curve as a border stream to the Miltenberg district around the Obernau glider airfield . There he ran the Altenbachsmühle until the beginning of the 20th century . After flowing through some fish ponds, the Altenbach passes under the state road 2309 and the route of the Aschaffenburg-Miltenberg railway line and flows north of Sulzbach from the right into the Main .

  • At the confluence

  • The Breitenbrunnen

  • The Elbertsbrunnen

Catchment area

It borders

  • in the north and northeast to the catchment area of ​​the Hensbach , which flows into the Main
  • in the southeast to that of the Wachenbach , which drains over the Sodener Bach into the Sulzbach
  • in the south to that of the Sulzbach itself, which flows into the Main
  • and in the northwest to that of the Main directly.

Altenbachgrund nature reserve

The Sandsee in the Altenbachgrund nature reserve

The Altenbachgrund nature reserve is located in the 2.4 km long and narrow forest valley of the meandering Altenbach. It includes the valleys of Hügelsbach, Sangenbach, Fichtenbach and Wachenbach. The 14.6 hectares large nature reserve Altenbach reason was expelled in 1985 and 2010 by the FFH area of the former military training area Aschaffenburg extended and other adjacent areas. The nature reserve, which is now around 295 hectares in size, was given the new name of the former training site Aschaffenburg and Altenbachgrund and the new number 00748.01 (previously 00235.01).

There are partly swampy floodplains with large occurrences of the giant horsetail and larger reeds in the remains of alluvial forests . There are bird species such as red backed killer , woodlark , little owl and goat milker , amphibians such as yellow-bellied toads , fire salamanders , natterjack toads and tree frogs, as well as reptiles such as sand lizards and smooth snakes .
