The Rhünda (pronounced as /de/), also called the Rhündabach, is a 12.9km (08miles) long, eastern tributary of the River Schwalm in the Schwalm-Eder-Kreis, North Hesse, Germany.
The Rhünda rises in the northern foothills of the Knüllgebirge. Its source is in the village of Dickershausen, part of the town of Homberg (Efze), at 327.5m (1,074.5feet) above sea level.
Initially the Rhünda flows northeastward through Sipperhausen and then after turns away from the Stöpplingskopf, towards north-northwest. In this direction it flows through, approximately parallel to the Bundesautobahn 7 to the east, Ostheim, then flows west past the Geschellenberg hill (324m (1,063feet)) and then just to the east of the town of Mosheim.
The river meets a small stream close to Hilgershausen then flows southwest down to Helmshausen. After passing a mill, and two basalt quarries, the Rhünda reaches the Felsberg district of Rhünda, after it crosses under Bundesstraße 253, just before reaching the Main–Weser Railway at about 159m (522feet) above sea level. There it opens into the River Schwalm, which, in turn, just after passing again under the railway line, flows in the River Eder.
The tributaries of the Rhünda are all, orographically, on the left. They are:
See main article: Rhünda Skull. In 1956, a severe storm caused the Rhünda to wash away its bank near the town of Rhünda, close to the present-day sports area.About 80cm (30inches) down a villager found a 12,000 years-old skull of a human, now known as The Rhünda Skull.
