Editing Rhine (section)

===Countries and borders===

During its course from the Alps to the North Sea, the Rhine passes through four countries and constitutes six different country borders. On the various parts:
* the Anterior Rhine lies entirely within Switzerland, while at least one tributary to Posterior Rhine, ''Reno di Lei'' originates in Italy, but is not considered a part of the Rhine proper.
* the Alpine Rhine flows within Switzerland till [[Sargans]], from which it becomes the border between Switzerland (to the west) and Liechtenstein (to the east) until [[Oberriet]], and the river never flows within Liechtenstein. It then becomes the border between Switzerland (to the west) and Austria (to the east) until [[Diepoldsau]] where the modern and straight course enters Switzerland, while the original course ''Alter Rhein'' makes a bend to the east and continues as the Swiss-Austrian border until the confluence at [[Widnau]]. From here the river continues as the border until [[Lustenau]], where the modern and straight course enters Austria (the only part of the river that flows within Austria), while the original course makes a bend to the west and continues as the border, until both courses enter [[Lake Constance]].
* the first half of ''Seerhein'', between the upper and lower body of Lake Constance, flows within Germany (and the city of [[Konstanz]]), while the second is the German (to the north) – Swiss (to the south) frontier.
* the first parts of the High Rhine, from Lake Constance to [[Altholz]], the river alternates flowing within Switzerland and being the German-Swiss frontier (three times each). From Altholz the river is the German-Swiss border until [[Basel]], where it enters Switzerland for the last time.
* the Upper Rhine is the border between France (to the west) and Switzerland (to the east) for a short distance, from Basel to [[Hunningue]]. Here it becomes the Franco (to the west) – German (to the east) frontier until [[Au am Rhein]]. Hence, the main course of the Rhine never flows within France, although some river canals do. From Au am Rhein the river flows within Germany.
* the Middle Rhine flows entirely within Germany.
* the Lower Rhine flows within Germany until [[Emmerich am Rhein]], where it becomes the border between The Netherlands (to the north) and Germany (to the south). At [[Millingen aan de Rijn]] the river enters the Netherlands.
* all parts of the Delta Rhein flows within the Netherlands until they enter the [[North Sea]], [[IJsselmeer]] ([[IJssel]]) or [[Haringvliet]] ([[Waal (river)|Waal]]) at the Dutch coast.
