Confluences are integral features in rivers characterized by complex 3D changes in flow
hydrodynamics and bed morphology and provide important ecological functions. This paper …

Confluences are a classic feature in riverine networks with important ecological and
morphological functions. A method to characterize the hydraulic complexity of a river based …

Morphology and dynamics of the confluence environment of the Paraná and Ivaí Rivers
(South Brazil) are studied using echo-sounding and velocity profile surveys (ADCP) with …

Confluences are common components of all riverine systems, and characterized by
converging streamlines and potential mixing of separate flows. The fluid dynamics of …

Habitat connectivity is considered a central factor shaping ecological communities, and the
effects of waterway barriers such as natural waterfalls on fish movements are expected to …

The confluence of the Paraná and Paranapanema Rivers is studied according to
morphology and dynamics. It is probably the only example of this type of fluvial environment …

Dams reduce the longitudinal connectivity of rivers and thereby disrupt fish migration and
the spatial distribution of species, impacts that remain poorly studied for some Neotropical …

Large river channel confluences are recognized as critical fluvial features because both
intensive and extensive hydrophysical and geoecological processes take place at this …

Hydrodynamic features of the confluence zone of large rivers are complicated because of
their three-dimensional flow structure. The confluence between the Rio Negro and the Rio …

The confluence phenomenon between the Rio Negro, with is black waters, and the Rio
Solimões, with its suspended white sediments, is well known and attracts thousands of …
