*The border follows one of the river banks, often in reference to a low-water mark. The exact location of the border is defined in a clear way - but one of the territories will lose terrain through {{w|erosion}}. When the river bends, erosion occurs at the outer bank and much less at the inner bank. | *The border follows one of the river banks, often in reference to a low-water mark.

| β | *The most usual definition of a riverine border uses the {{w|talweg}}. The talweg (German for "valley path") always follows the line of the deepest points in the water body. Especially at river bends, the talweg is rarely in the middle of the river. Incidentally, the talweg also signifies the navigable zone of a river. In terms of {{w|natural border}}s, one counterpart of a talweg is the {{w|drainage divide}}, but these divides are hard to recognize on a map and | + | *The most usual definition of a riverine border uses the {{w|talweg}}.

The Mexican-US-Border that follows the Rio Grande is one of the most prominent examples of an international border that needs meticulous regulation. Thus, the {{w|International Boundary and Water Commission}} was created. This commission was involved when the two nations rectified the course of the river, ceding equal amounts of land to each other. The Canada-US-Border is overseen by a similar commission. There is also a strange section on the border to Canada, which Randall mentions in the comic [[1902: State Borders]]. | The Mexican-US-Border that follows the Rio Grande is one of the most prominent examples of an international border that needs meticulous regulation.
