The rivers of North-West Europe are good examples of

The rivers of North-West Europe are frequently cited as classic examples of a barbed drainage pattern. This pattern is characterized by a discordant junction where tributaries appear to flow upstream before joining the main river, often resulting from river capture that reverses the main stream's direction while tributaries maintain their original orientation [2]. In North-West Europe, particularly in the context of the Rhine and its historical evolution, tectonic activity and glaciation have significantly altered drainage lines [3]. The Rhine system, which drains large parts of Germany, France, and the Netherlands, has undergone complex changes due to the European Cenozoic Rift System [3]. While trellis patterns are common in folded mountains like the Chotanagpur Plateau [1] and radial patterns occur in hilly regions like Amarkantak, the specific historical river captures in the North-West European plain make the barbed pattern a distinctive feature of the region's geomorphology.
