The Stadelbach is a creek over five kilometers long in the Enzkreis in Baden-Württemberg , which rises as a Seegraben east of Friolzheim and flows into the Würm from the right below the village of Mühlhausen an der Würm von Tiefenbronn .

geography

course

The Stadelbach rises as a ditch on the northwestern slope of the Dünnberg, the northeasternmost branch of the Betzenbuckel in the nature reserve named after it in the Heckengäu . Over a length of approx. 4 kilometers, it flows canalised from there, partly underground, in a trough on the northwest side of the range of hills of the nature reserve, past the Tiefenbronner Seewiesen . There it crosses under the Tiefenbronner Straße (K 4653) and then flows in the same south-westerly direction under the name Stadelbach, until it flows into the Würm from the right just below the Tiefenbronn village of Mühlhausen an der Würm .

  • (Ditch from the direction of the Mühlhof), from the right to about 425  m above sea level. NHN after crossing under the L 1176 Friolzheim – Heimsheim, 0.7 km
  • Seegraben (!), From the right to about 415  m above sea level. NHN in the Tiefenbronner Seewiesen, 0.6 km
  • RiverIcon-SmallLake.svgPasses a pond on the right of the run at about 400  m above sea level. NHN at the entrance to the forest ridge of the lower reaches, over 0.1 ha.

nature

In the middle of the 20th century, the bed of the Seegraben was straightened and partially covered with concrete half-shells, its embankments paved with natural stones. The aim was to make the Seegraben, a third-order body of water, more suitable as a receiving water for draining and relieving the rainwater and mixed water system of Friolzheim. However, this led to the fact that the water, unlike at the time of its freely meandering course before, drained faster and now, especially in late summer, often has a very reduced flow or even falls completely dry.

According to a report from 2014, Friolzheim had problems with flooding due to an insufficiently dimensioned sewer system, which should therefore be upgraded. Since the Seegraben receiving water running along the edge of the village absorbs the water that is then carried away more quickly, this measure would, however, increase the already existing tendency to flood in heavy rain. Therefore, a relief by a retention basin or a widening of the trench cross section of the sea trench was considered.
