Consequently, the Paraguay-Cuiabá confluence is able to shift from an obtuse-angle working mode to a confluent meander bend working mode according to the hydrological conditions. In the Pantanal wetlands, the strong flood wave is responsible for significant variations of the discharge and momentum-flux ratios within the confluence. A single bend might or might not be calla meander, just a bend. Here we analyze a confluence with an obtuse-angle planform-the tributary enters the confluence at an angle higher than 180°-that abruptly curves to join the main river. Where Any group of bends describes a meandering stream.

As a river makes its way through an area that is relatively flat, it often develops bends as it erodes. A meander is when water flows in a curvy, bendy path, like a snake. For this Find-A-Feature challenge, we challenge you to look around you for examples of a meander. However, most investigations have concentrated on the junction of two straight channels, and few studies have focused on confluent meander bends or obtuse-angle confluences. A meander is another name for a bend in a river. A meandering channel commonly is about one and. Meanders, named from the Menderes (historically known as the Maeander) River in Turkey, are most often formed in alluvial materials (stream-deposited sediments) and thus freely adjust their shapes and shift downstream according to the slope of the alluvial valley. Junction planform plays a pivotal role in the confluence hydrodynamics. meander, extreme U-bend in the course of a stream, usually occurring in a series. The results are compared with the classic theories of the processes in meander bends. The spatial patterns of erosion and deposition over meander bends are analysed relative to the measured and modelled flow field and sediment transport. River confluences are notable features in the drainage system with complex hydrodynamics, bed morphology, sediment transport, and mixing processes. the flow-based changes and formations over meander bends and to build the computational models.
