Sauer (Rhine)

The Sauer is a river in France and Germany, a left tributary of the Moselle.

Geography and Course:

The Sauer rises in the Vosges Mountains in France, near the village of Fontenoy-le-Château in the département of Vosges. It flows generally northwards, passing through the département of Bas-Rhin in the Alsace region. After crossing the border into Germany, it continues through the state of Rhineland-Palatinate. The Sauer ultimately flows into the Moselle near Wasserbillig, on the border between Germany and Luxembourg.

Hydrology:

The river is approximately 173 kilometers (107 miles) long. A significant portion of its course forms the border between Germany and Luxembourg.

Significance:

The Sauer valley is known for its scenic landscapes and is popular for hiking and other outdoor activities. The river also plays a role in local agriculture and supports a diverse ecosystem. The German-Luxembourg Nature Park (Deutsch-Luxemburgischer Naturpark), which straddles the border, encompasses a large section of the Sauer valley, highlighting its ecological importance.

Etymology:

The name "Sauer" is believed to be of Celtic origin, likely derived from a word meaning "acid" or "sour," possibly referring to the water's properties.
