Upper Rhine
Upper Rhine (German: Oberrhein [ˈoːbɐˌʁaɪn] ⓘ; French: Rhin Supérieur is the section of the Rhine between the Middle Bridge in Basel, Switzerland, and the Rhine knee in Bingen, Germany. Representing kilometres 167 to 529 of the river it is surrounded by the Upper Rhine Plain (Oberrheinische Tiefebene). Most of its upper section marks the France–Germany border.
The Upper Rhine is one of four sections of the river between Lake Constance and the North Sea, and is succeeded downstream by the Middle Rhine and Lower Rhine; only the High Rhine and Alpine Rhine lie above it. The countries and states along the Upper Rhine are Switzerland, France (Alsace) and the German states of Baden-Württemberg, Rhineland-Palatinate and Hesse. The largest cities along the river are Basel, Mulhouse, Strasbourg, Karlsruhe, Mannheim, Ludwigshafen and Mainz.
The Upper Rhine was straightened between 1817 and 1876 by Johann Gottfried Tulla and made navigable between 1928 and 1977. The Treaty of Versailles allows France to use the Upper Rhine for hydroelectricity in the Grand Canal d'Alsace.
On the left bank are the French region of Alsace and the German state of Rhineland-Palatinate; on the right bank are the German states of Baden-Württemberg and Hesse. The first few kilometres are in the Swiss city of Basel.
Around 35 million years ago, a rift valley of about 300 kilometres (190 mi) long and 50 kilometres (31 mi) wide came into being between the present cities of Basel and Frankfurt. This was due to tensile stresses in the Earth's crust and mantle, which resulted in lowering the earth's surface. The moat has been partially filled up again by sedimentation. On the edges we find mountain ridges, the so-called "rift flanks". On the eastern side, they are the Black Forest and Odenwald mountains, in the west the Vosges and Palatinate Forest. During the Tertiary, the High Rhine continued west from Basel and flowed via the Doubs and the Saône, into the Rhône. The rift diverted the Rhine into the newly formed Upper Rhine Valley.
The Rhine knee at Basel marks the transition from the High Rhine to the Upper Rhine with a change of direction from West to North and a change of landscape from the relatively small-chamber high-Rhine cuesta landscape to the wide rift zone of the Upper Rhine Rift Valley. The two largest tributaries come from the right: the Neckar in Mannheim, the Main across from Mainz. In the northwest corner of the Upper Rhine Valley, at Rhine-kilometre 529.1, near Bingen, where the Nahe flows into the Rhine, the Rhine flows into a gorge in the Rhenish Massif and thereby changes into the Middle Rhine.
Tributaries are listed in direction of flow (bottom to top), with the nearest settlement to their confluence given in brackets.
