The Wälzebach is a 9.0 km long, orographically left , western tributary of the Schwalm in northern Hesse . It rises near Odershausen , a southern district of Bad Wildungen in the Waldeck-Frankenberg district , and flows into the Schwalm near Bad Zwesten in the Schwalm-Eder district . Its catchment area is 19.5  km² , and the mean water discharge ( MQ ) at the estuary is 156 liters / second.

course

The source of the Wälzebach is in the Kellerwald and in the Kellerwald-Edersee Nature Park at 350  m above sea level. NHN on the eastern edge of Odershausen in the small village park there on Wildunger Strasse. It is located directly on the watershed between Schwalm and Eder , because the Sonderbach with the Kaltebornsbach, which runs just 400 m further west on the western edge of the village, drains north to the Wilde and thus to the Eder.

The stream initially flows about 350 m to the east, then turns to the southeast and after another 100 m passes under the B 485 / B 253 . Shortly afterwards it turns to the south and then after 400 m again to the southeast. It now flows around 1.35 km in a long right-hand bend that gradually bends to the south, around the right (west) village of Braunau , a district of Bad Wildungen. At the eastern end of the village, the stream crosses under the B 485 to the south, immediately afterwards takes on the Kirschenbach coming from the west and then runs another 450 m to the south. Then at the Braunau sewage treatment plant it enters a narrow, ravine-like valley bordered on both sides by forest, which it follows in a generally south-easterly direction over a length of about 3.7 km in several turns to the outskirts of the core town of Bad Zwesten and the confluence there of the Gersbach coming from the west . The B 485 accompanies it on its left bank for the entire route, 150 m south of the Gersbach estuary takes up state road L 3296, which also comes from the west, and then bends to the east.

The Wälzebach, which most recently curved around the Treisberg (311.6 m) to the west, crosses under the L 3296, enters the Löwensteiner Grund from the Kellerwald , passes about 150 m further south the location of the long-gone mill " uff dem Weltzebache " and turns there to the east. After about 1000 m it reaches the southern residential areas of Zwesten and disappears into the underground sewerage on Bachstrasse. It passes the historical center of the village with the church and only comes back to the surface about 330 m further east. After about 270 m of flow in an east-southeast direction, between Raiffeisenweg and Brunnenstrasse (B 485), it crosses under the B 3 ( Marburg - Kassel ) and takes in the Paulbach coming from the west immediately before the underpass. Finally, it winds in four large curves the last 750 m to the southeast, past the Zwesten sewage treatment plant and the Bruchmühle, to its confluence with the Schwalm on the western slope of the Altenburg (432.7 m).

prehistory

Today the Schwalm runs through the Löwensteiner Grund and leaves it in the northeast through the Schwalmpforte . As Schmidt-Döhl has convincingly demonstrated, it took over this river landscape from the Gilsa , Urff and Wälzebach, which drained the Kellerwald to the east in the Pliocene , and redesigned it further. The Wälzebach once had a much larger catchment area, therefore also carried significantly more water and formed the breakthrough valley of today's Schwalmpforte. However, due to the retrograde erosion of the Sonderbach near Odershausen, its two original source rivers Talgraben and Kaltebornsbach were lost to the Eder river system, and the Urff, which now flows directly into the Schwalm, previously flowed to the Wälzebach. The very steep north-west slope of the Altenburg, along which the Schwalm runs today, is an original impact slope of the Wälzebach.
