Rates and patterns of temperature mixing at a small stream confluence under variable incoming flow conditions
River confluences are locations in the fluvial network where two incoming flows, often with distinct chemical, thermal, and physical properties, converge and start to mix. The degree of mixing that occurs within a confluence influences ecological and water quality conditions locally as well as …

Measuring flow and mixing at stream confluences using large-scale particle image velocimetry, in-stream techniques, and small unmanned aerial systems
Confluences, locations where two rivers flow into one another, are characterized by the mixing of water, dissolved nutrients, chemicals, pollutants, and sediment. The process of mixing at confluences is inherently related to patterns of confluent flows, yet the complex nature of confluence …

Flow structure of an asymmetric large river confluence
… and confluence morphodynamics at a large river confluence with an asymmetrical planform. Five sets of field measurements of three-dimensional velocity components and bed topography at the confluence of the Wabash River and Embarras River along the Illinois-Indiana border reveal a complex …

Numerical, field and laboratory studies of three-dimensional flow structures at river channel confluences
… nature of three-dimensional flow structures at river channel confluences. Previous work has shown that junction angle is an important control on the flow patterns at channel junctions since it affects the degree of curvature of flow from each tributary and sets up secondary circulation cells …

Satellite remote sensing of mixing dynamics at a large river confluence
… are detectable on remotely sensed images of rivers downstream from confluences, no systematic methodology has been developed for assessing mixing over distance of confluent flows with differing suspended sediment concentrations. In contrast to field measurements of mixing below confluences, …

The fluvial dynamics of confluent meander bends
… sediment transport, and bed morphology at river confluences. Previous experimental, field, and modeling studies of confluence dynamics have focused mainly on junctions formed by straight approach channels that meet at angular configurations before entering a straight receiving channel. In …
